Nano Micro perforation - archipelagos of technical possibilities

optical porosity and dyne - surface tension - vision control at fast moving webs

Nano Mikroperforation von Warenbahnen

Für unterschiedlichste Applikationsbereiche werden Materialbahnen wie Zigaretten-, Mundstückbelag, Filter, beschichtete Spezial, Kraft-, Sack- oder Verpackungspapiere, Vliesstoffe, spun-bonded Non-Woven, technische Textilien, Fabrics, Laminate usw. mit Flächengewichten von 20 g/m2 bis zu 150 g/m2 Elektrostatisch – ESP – Nano Mikro oder Laser- oder mechanisch Mikro oder Makroperforiert.

Unter elektrostatischer NANO MIKRO PERFORATION sind statistisch unregelmäßig verteilte, in der Größe um ca. 50 % variierende und analog hierzu unter LASER oder Mikro/Makro mechanische PERFORATION, gleichmäßig angeordnete und im Durchmesser etwa gleichgroße, nach Möglichkeit runde, gradfreie Löcher und Lochreihen verschiedenster Anordnung zu verstehen.

Die mit dem menschlichen Auge unsichtbaren, elektrostatischen ESP Nano oder Mikroperforationen können flächen- wie auch zonenförmig in bestimmten Abständen innerhalb der Bahnen verteilt sein, wobei erzielbare Lochgrößen sich im Bereich von 1 - 120 um Durchmesser und Lochsequenzen von 1.5 – 16 Million Poren pro Sekunde bewegen. Zonenanordnungen sind in der Regel in Breiten von 2 bis 6 mm und mit Porendichten von 150 - 250 Poren pro cm2 ausgeführt, wobei Flächenperforationen Lochdichten bis zu 2 Million Poren pro m2 generieren. ESP Perforationen ermöglichen Porositätsbereiche von 80 – 2500 C.U., Bahnbreiten von 100 bis 2000 mm bei Bahngeschwindigkeiten bis zu 500 m/min, abhängig von der Porosität und Materialkonsistenz zur Perforierbarkeit.

Respektive durch gepulste oder auf geweitet sowie fokussierte Laserstrahlen sind Lochgrößen von 60 - 200 um bei Lochdichten von typischer Weise 10 – 30 Löcher pro cm, Lochsequenzen von 100.000 bis 500.000 Löcher pro Sekunde, bei maximal 32 Laserlochreihen über die Bahnbreite verteilt, möglich. Deren Porositätsbereiche bewegen sich zwischen 100 – 3000 C.U., in der Regel mit Bahnbreiten von 100 – 500 mm bei Bahngeschwindigkeiten bis 600 m/min, abhängig von der Porosität und Materialkonsistenz zur Perforierbarkeit.

Eine wesentliche Kardinalforderung, die für viele Applikationsbereiche und Produkte mit Vliesstoffen, Sack- oder Verpackungsbahnen, Non-Woven usw. mit einer Gas- oder Wasserdampfdurch- ABER Wasserundurchlässigkeit verbunden ist, finden sich im Anwendungsbereich der ELEKTROSTATISCHEN NANO MIKRO PERFORATIONSTECHNIK wieder, da Wasser aufgrund der höheren Oberflächenspannung die relativ kleinen Nano- oder Mikroporen nicht durchdringen kann. Diese und weitere physikalische Vorteile der relativ kleinen Poren fordern regelrecht den Einsatz der ESP Perforationsmethode, da die Applikationserfüllungen mit anderen Perforations- oder Prozessverfahren NICHT machbar, zu teuer oder unwirtschaftlich sind.

Perforation von Mundstückbelag oder Zigarettenpapierbahnen zur Ventilation von Filterzigaretten

Die elektrostatische ESP Perforation ist seit mehr als 25 Jahren zur Ventilation von Nichtfilter - oder Filterzigaretten eingesetzt, um einen gezielten und gesteuerten Luft Bypass, zu erzeugen. Hierzu wird das Zigarettenpapier für wenige Nichtfilter- oder bei fast allen Filterzigaretten das Mundstückbelagpapier elektrostatisch ESP OFFLINE oder mit Laserstrahlen in Zonen oder Lochreihen OFFLINE oder ONLINE perforiert, um Schadstoffanteile wie Nikotin und Kondensate für die Raucher auf vorgegebene Werte zu reduzieren und im Weiteren den Ventilationsgrad der Zigaretten gesteuert zu beeinflussen.

IPM – International Perforation Management – hat verschiedene Laser- und Elektrostatische Perforationsverfahren, insbesondere auch für neue Produkteigenschaften, entwickelt, deren Systeme und Produktionsmaschinen weltweit im Einsatz sind.

Optische online Permeabilität oder Porosität Messung

Da die naturporösen oder zu perforierenden Bahnmaterialien mit Bahngeschwindigkeiten bis zu 600 m/min bewegen und in Bahnbreiten bis zu 2000 mm und mehr vorhanden sind, gestaltet sich eine pneumatische, also bahn berührende Porositätsmessung, exorbitant schwierig. Hinzukommend sind diese Messmethoden mit den Nachteilen der Bahnzugserhöhung, des Materialabriebs, Faltenbildung, Undichtigkeit im Messkopfbereich, starken Verschmutzungen, Nichtlinearitäten und Kalibrierungsschwierigkeiten stets verbunden.

Daher bieten sich optische Messverfahren zur Transmissionsmessung als Funktion der pneumatisch-statischen Gasdurchlässigkeit für naturporöse oder Nano, Mikro bzw. Makro perforierte Bahnen an. Dabei sind die gestellten Anforderungen aufgrund der eingangs genannten Produktverarbeitung und online Kontrolle, extrem kleinen geometrischen Porenabmessungen, relativ hohen Bahngeschwindigkeiten und guter Messwertreproduktion mit der optischen Porositätsmesstechnik in idealer Weise zu lösen.

Hierzu hat IPM International Perforation Management eine Reihe neuer, patenangemeldeter optischer Messverfahren und Systeme in stationärer oder traversierender Ausführung entwickelt, die weltweit im Markt eingeführt sind.

Zukunftsperspektive

Die elektrostatische ESP Nano- oder Mikroperforation findet vorzugsweise ihre Anwendung in Bereichen der Veredelung von Feinpapieren, Verpackungsbahnen, Vliesstoffen, Non-Woven, Filter-, Sack- oder Kraft- sowie Spezialpapiere verschiedenster Art, insbesondere bei der zusätzlichen Behandlung von Bahnmaterialien zur Erzielung besonderer Eigenschaften, welche aus physikalischen oder prozesstechnischen Gründen NICHT mit anderen Verfahrenstechniken erreichbar sind.

Die state-of-the-art, industrietaugliche und im Dreischichtbetrieb zuverlässig arbeitende ESP Perforationstechnik, deren Integrationsmöglichkeit in vorhandene Umroller- oder sonstige Bahnlaufanlagen sowie auch als völlig eigenständig arbeitende Perforationsmaschinen möglich sind, wird zukünftig neue Anwendungsbereiche erschließen und Produkte mit besonderen Eigenschaften entstehen lassen.

Zusammenfassung

Nur die elektrostatische Mikroperforation ermöglicht durch fein dosierte Energieeinkopplung und Funkenkanalerzeugung eine nano oder mikrofeine Ventilation für Packmittel mit erhaltenen Barriereeigenschaften, Schaffung von Atmungseigenschaften für Domestik- und Massenprodukte, industrielle oder medizinische Nano oder Mikromembranen mit Mikrocluster, Vliesstoffe und insbesondere Papierbahnen verschiedenster Art bei relativ großen Bahnbreiten und Transportgeschwindigkeiten, welche aus physikalischen oder prozesstechnischen Gründen nicht mit anderen Verfahrenstechniken erreichbar sind.

Dieser Trend wird sich für spezielle Produkteigenschaften und Anwendungen fortsetzen. Die state-of-the-art, industrietaugliche und im Dreischichtbetrieb zuverlässig arbeitende Nano Mikrocluster Perforationstechnik, deren Integrationsmöglichkeit in vorhandene Umroller- oder sonstige Bahnlauf- und Materialbewegungsanlagen sowie auch als völlig eigenständig arbeitende Produktionsmaschinen möglich sind, wird zukünftig neue Anwendungsbereiche erschließen und Produkte mit besonderen Eigenschaften entstehen lassen.

Durch Weiterentwicklungen von hybriden, modularen Schaltungstopologien mit IGBT, MOSFET, FRETFET oder HVFET zur Erzeugung stromgesteuerter Hochspannungsentladungsimpulse im Zeitfenster von 10 ns bis 15 µs und Pulsendladungen von 0.1 bis 3 mJ hat die Nanotechnologie und Submikroperforation auch im Bereich der Feinpapierveredelung und Verpackungsstoffverarbeitung Einzug gehalten. Auf die anderen zuvor genannte Applikationsbereiche ist dies für die beschriebene Mikroclustertechnologie übertragbar.

Nano micro perforation of diverse running webs

Material webs such as cigarette-, mouthpiece tipping paper, filter-, coated special papers, force papers, bag papers or packing papers, bonded fabrics, spun bonded non-woven, technical textiles, fabrics, laminate, etc. with base weights from 20 g/m2 to up to 150 g/m2, up to 20 g/m2 LPDE coating films, are perforated electro-statically – ESP – nano/micro or laser or mechanical micro or macro for different application purposes.

For a better comprehension: Electrostatic NANO MICRO PERFORATION are statistically irregularly distributed, varying by size up to 40 %, and analogically, under LASER or micro/macro mechanical PERFORATION, evenly arranged in diameter about the same in size, at best non-inclined holes und rows of holes of diverse arrangement.  For the human eye invisible electrostatic nano or micro perforations may be arranged in areas as well as in zones with specific distances within its web. The sizes of the holes range from 1 to 120 µm in diameter and hole sequences from 1.5 to 16 million pores per second. 

Arrangements of zones are usually carried out in width from 2 to 6 mm and pore density of 15 to 250 pores per cm2 whereas the perforation of areas results in pore densities of up to 2 million pores per m2. ESP perforations allow for porosity levels from 80 to 2500 C. U., width of webs from 100 to 2000 mm at web speeds of up to 500 m/min, depending on the porosity and material consistency in relation to its ability to perforate.

Laser perforation

Possible to perforate by pulsed or enlarged and focussed laser beams are hole sizes from 60 to 200 µm at density of holes of typical 10 to 30 holes per cm, hole sequences from 100,000 to 500,000 holes per second at a max. of 32 punctured rows by laser distributed over the width of the web with traditional systems or machine. Their porosity levels range from 100 to 3000 C. U., normally with web widths from 100 to 500 mm at web speeds of up to 600 m/min, depending on the porosity and material consistency in relation to its ability to perforate.

IPM owns development of LASER PERFORATION technology LPM-1 is patent grand and operates with quadruple beam inputs to a high power CO2 laser beam multiplexer to generate up to 200 individual laser perforation rows across the web, combines automatic laser perforation head positioning, focus setting, web speeds up to 400 m/min, web widths up to 2,000 mm, up to 4,000,000 holes per second, jumbo-roll-by-roll production, optical online permeability and perforation line positioning control, porosity feedback and other features. Each laser perforation lines are archive able from 100 up to 2,000 C.U.

The conception of high-power laser beam multiplexers enable many possibilities in other industry application fields as cutting, cut-offs, welding, surface finishing, drilling, polishing, forming, surface treatment, roughness improvement, etc.

Each of the 200 single perforation head can be positioned across the running web or static positioned material. The automatic processes, equipments and devises opening completely new possibilities in industry, science, military or space laser application.

A new patent pending Micro Laser Line perforation technology MLL-1 generates sinus, waves, zigzags or other kinds of perforations designs as multiple pairs of micro laser lines in the web direction. Provide for tipping, cigarette, packaging or other kind of paper webs.

These special features of micro laser line perforation enables fundamental new product characteristic in perforation scripts, e.g. for mouthpieces with tipping paper on cigarette filters, products indication with visible perforation holes as brand name or company logo, anti counterfeiting designs, perforation cryptogram, etc. As well is that process to use by other material, industry and application field.

Ventilation of mass products

Electrostatic perforation has been used since 30 years for ventilation of non filter, RYO or filter cigarettes to create a directed and guided air bypass or Lindstroem principle. For this purpose, cigarette paper for some non filter or RYO cigarettes and almost every kind of filter cigarettes tipping papers are perforated electro statically OFFLINE in zones from 2.0 – 6.0 mm width or in rows with ONLINE or OFFLINE by use of slow, fast flow, sealed-off or SLAB CO2 gas or diode laser in order to reduce the harmful substances such as nicotine and condensate down to allowed values. Another effect is the possibility to control the degree of ventilation of Cigarettes.

Online micro perforation, porosity profiling

Many years ago IPM had developed a multiple online electrostatic micro perforation OESP-1 units at cigarette making machines which was patent applied with EP0460369 and DE4018209.

http://www.freepatentsonline.com/EP0460369.html

The method and the device for electro-erosive perforation of cigarette paper basically operates with at least two pairs of electrodes which are ignited at the same time in such a manner that each perforation section is treated twice in order to provide a corresponding intensity of perforation, taking into consideration the duration of ignition and the web speed. In particular, the invention operates with at least four pairs of electrodes (I to IV), between which the web (10) of cigarette paper to be perforated is moved through. The cigarette paper is moved in the longitudinal direction of the cigarette to be produced later, the width corresponding to the circumference of the cigarette plus an overlap section for bonding. Perforating is carried out transversely to the direction of movement, that is to say an accurately defined zone section is produced around the circumference of the cigarette. The pairs of electrodes are arranged at a distance which corresponds to half the cigarette length (a, b, c) when four pairs of electrodes are used. The first and the third pair of electrodes are ignited simultaneously. A distance dependent control causes the second and fourth pair of electrodes also to be ignited simultaneously when the previously perforated sections have traveled the distance of half a cigarette length. Each section is perforated four times, the speed at which the web (10) can be moved being determined not by the spacing (half a cigarette length) of the pairs of electrodes but by the spacing of the pairs of electrodes in each case simultaneously ignited (one cigarette length). This provides for uniform, intensive and very powerful perforation and the cigarette paper treated can be continuously supplied to the cigarette machine for further processing in the longitudinal direction of the cigarette.

That electrostatic micro perforation process enables cigarette or tipping paper while cigarette making processes to reduce nicotine and condensate levels for non-filter and filter cigarettes as well. The OESP-1 devices opens fully new possibilities for cigarette or tipping paper ventilation during cigarette manufacturing by entire perforation cassettes integration into cigarette making machines as Max-S, Protos 80, Protos 90, Mark-9 etc.

Advantages during manufacturing

Compact all-over-dimensions, direct mechanical integration of perforation units, easy functional interfacing and full EMI acceptance in order of EN or NEC standards archiving high production efficiencies with controllable ventilation grades on highly automated cigarette making machines.

• Patented, powerful, dual high frequency switching electronics and multiple perforation performances of the circumference of each cigarette enables problem less perforation on high-speed cigarette making machines up to 12.000 cpm

• Porosity ranges from 50 up up to 400 C.U.
• pore densities from 25 up to 300 pores/cm2
• hole size from 30 up to 80 micron
• cigarette ventilation grades up to 45 % are archive able.
• All necessary perforation, production parameters are stored and controlled by microcomputer operation, i.e. geometrical and synchronized positions of perforation lines, zones etc., pore density, perforation zones width and distributions, perforation profile and porosity ranges for each cigarette brand
• Porosity profiles over the length of each non-filter cigarettes are possible.
• Furthermore single, multiple, different or equal groups of single perforation zones around the circumference of each cigarette for non-filter, RYO even tipping paper for filter cigarettes are possible.
• All stored parameter sets are linked to the PLC system.
• Different micro perforation designs and porosities of each cigarette brand are flexible to define and controllable during all production processes.
• Air ventilation levels are exactly defined and, due to online feedback, can be kept constant by means of perforation system design and porosity distribution.
• For non filter cigarettes for example, perforation can be effected over the entire length and circumference of the cigarette.

Liability and system investment

The ESP process OESP-1 has a high liability and is realizable with low investments and low running costs when compared with online macro or micro laser perforation processes. An online porosity control system OPSS-1 monitor continuously the air permeability, called optical online porovision or porosimeter, with a state-of-the-art technology to obtain a close-loop/feed-back to the perforation unit to keep ventilation grades constant.

Conclusion: Online micro perforation processes are possible to use for other mass products and application fields with full system integration in entire production lines as bag, sack, packaging manufacturing etc.

Special applications and product properties with ESP electrostatic perforation

One of the foremost postulation which can be applied to many application purposes and products containing bonded fabrics, bag- or packaging papers, non-woven, etc. with gas or steam permeability but water impermeability will be found at the application stage of the ELECTROSTATIC NANO/MICRO PERFORATION TECHNOLOGY.  Which means pore sizes from 0.5 up to 10 µm diameter by up to 5 million per m2. This is due to the water’s greater surface tension which hampers the permeation through the relatively small nano or micro pores. These and other physical advantages of the relatively small pores necessarily demand the application of the ESP perforation method because alternative perforation or processes are NOT feasible, too expensive or simply uneconomical and would not lead to a successful application.

To archive new ESP demands IPM developed/patent grand new electronic perforation circuits which working as upward converters with IGBT’s, MOSFETS’s or HVFET’s for power pulses from 1 µs up to 25 µs, high current peaks up to 300 Amps, base frequencies up to 200 KHz on ferrite transformers to generate 50 KVss to each sparking electrode.

Sophisticated multi functional optical online sensor systems 

IPM has developed a number of new, patent pending, stationary, scanning optical control processes, devices and systems for fast moving webs or fabrics to detect very precise and reproduce their specified product properties in online operation during production.

Introduction

OPSS-1 OPRL-1 vision control systems are equipped with multiple IR, NIR, VIS monolithic spectral color sensors, precision line lasers, CCD imagine devices, DSP, ATMEL and INFINEON sensor internal controllers, own firmware, high speed data link, at scanning speeds from 20–500 mm per second, at web widths up to 5000 mm, measuring gaps from 2.0-5.0 mm, optical inline detection of permeability, porosity, spectral transmission, opacity, extinction, particle absorption, porosities ranges from 80 up to 5000 C.U. (Coresta), respective from 50 down to 3 Gurley, position control of micro perforation lines with 0.1 mm accuracy, nano micro pores from 50 nm up to 200 micron diameter by up to 300 pores per cm2. With real time data determining of certain parameters, optical transmission, spectral grades, porosity integrals, envelope curves, internal calculated measuring values.

Thus direct with close loops and feedbacks to the power electronics of fabrics treatment units. Micro perforation or other system makes it possible to compensate any changes in web treatment parameters and their partial locations so that each jumbo roll as well single, quad bobbin sets can be produced quantity and quality controlled without intermediate stops in order of ISO 9001/9002 certifications.

Thus sophisticate, precise, liable, repeat accuracy, easy visualized, optical online measurement techniques archives perfect ways to control and convert pneumatic, fluid, gas, jet streams, static permeability, naturally porous grades, filtration levels, breathable or ventilation effects, etc. at fast moving webs. Their conditions can be easily met by using optical transmission technology thanks to described processing in fully online stationary or scanning control units, extremely small pore dimensions, high fabric speeds up to 1000 m/min by high repetition rates. That completely independent from base material properties as consistency, coloring, density, formation, pin holes, smoothness, stretching, shrinking, brightness, opacity, optical spectral property, gauging thickness weight, moisture content and other known influences.

Application

The electrostatic nano or micro perforation, including Co2 slab fiber yag excimer diode laser, other material going trough or surface treatment, as well for micromachining and nanotechnology, is usually used depending on quality at fine, rotogravure or offset printing, holographic or publishing paper, writing, magazine, newspaper, packaging, bonded fabrics, non-woven, filter, coffee, tea, bag, sack, craft, food, fresh fruit, force, reinforce, tipping, cigarette, plug wrap, fiber, facial tissues, toilet, decoration, wallpaper, gift, watermark, towels, bleached dyes shiny or clay, recycling, booklet, bible or other special paper, certain plastic films, foils, coating, laminating, extruding, Polyofine, Polysulfone, Elastomer, textile, Polymer or most of that varied types.

It is also used especially for additionally treating materials when aiming special characteristics by physical or regular process reasons cannot be achieved by other process technologies. Material base weights from 10 up 150 grams per m2 by thickness from 5 up to 100 micron are possible to use. Including defect inspection, process automation, moisture vapor transmission rate, abrasion resistance for lamination of waterproof and breathable fabrics.

Our state-of-the-art, industrially approved, sophisticated, compact, multi functional, optical online sensor scanning systems together or without electrostatic, laser perforation technology operates precise and reliable 24/7, are integrate able into existing rewinding, slitting, spooling, spreading, printing, labeling, complex production lines or other machines and other production processes as well. Also, they can be used as completely independent micro surface-all-over or zone perforation units. Fully new ranges of applications will be made available total new products with special features.

Optical online permeability or porosity vision control

Since naturally porous web materials or web materials to be perforated are processed with speeds of up to 600 m/min and web widths of up to 2000 mm are used, a pneumatic porosity measuring, hence measuring whilst touching the web are highly difficult. Further difficulties of pneumatic measurements are the disadvantages of rising of web tension, material abrasion, folding, leakage at measuring head, impurities, non linear processing and calibration problems.

Thus, optical measuring offers better ways for transmission measuring the pneumatic static permeability for naturally porous or nano, micro or macro perforated webs. The conditions mentioned above can be easily met by using the optical porosity measuring technology thanks to the mentioned product processing and online control, extremely small pore dimensions, relatively high track speeds and a good value repetition.

That full independent from principle material facts as consistence, thickness, weight, colouring, formation, smoothness, brightness, opacity, and other influences.

Therefore, IPM – International Perforation Management – has developed a number of new, patent pending, stationary and transverse optical measurement processes and systems which working with multiple colour sensors, a precision line laser, scanning speeds from 20 – 200 mm per second, porosity ranges from 80 up to 3000 C.U., perforation lines detection by 0.1 mm, nano micro holes sizes from 0.5 up to 2000 µm diameter and up to 250 holes/cm2 to determine all data in real time with an internal controller unit in order of multiple light transmissions and perforation profiles to determine envelope curves as well porosity integrals.

Optical online OPSS-1 porosity permeability vision scanning systems

Patent pending DE10251610 – China patent grand 200310104764

Introduction

A German-Thai high-tech, engineering company has developed an optical online porosity or permeability scanning system. It works with two different multiple sensors units, i.e. precise line laser, colour sensors and internal controller unit for real-time positioning and porosity control in light transmission mode whilst scanning across the fast running webs up to 600 m/min.

The main advantage compared to existing technologies is the measurement of perforation zone/line positions and porosity levels in the same time while the scanner system across the running material web up to 2000 mm width.

Science, R&D, Universities, industrial partners for a licence agreement and / or technical co-operation are sought.

Working principle

The porosity control of natural porous and/or perforated web material in laser or electrostatic perforation systems which are produced in speed ranges up to 600 m/min and web widths up to 2000 mm is difficult to measure with pneumatic systems because of following disadvantages: web tangency, web toughing, material flaking, formation of folds, dust and dirt entering the system.

These difficulties can be overcome with stationary or scan, optical porosity measurement systems for porosity ranges from 80 up to 5,000 Coresta units (ml/2cm2/min) respectively 3 to 50 l/m2/Sec. (Franksystem) by nano, micro or macro holes sizes from 0.5 up to 500 microns and hole densities from 10 macro holes per cm up to 400 holes per cm2

The optical online porosity control technology is designed to scan perforation zones with a multiple sensor and their positions with a precision line laser to determine all data in real time with an internal controller unit. It controls roll material or bobbin formats, either as a stand-alone unit or mechanically coupled with existing scanning units which measure the material weight, thickness, opacity, density, brightness, smoothness, formation, etc.

By laser and electrostatic perforation in bobbins and wide paper web formats optical online control processes and their devices are indicated with transverse movements across the web and simultaneously collections of perforation positions and porosities by two different sensor systems.

Both measuring systems move transversely between 50 up 400 mm/Second over the fully web width. They consist of a line laser detect the quality and position of single holes, groups of holes or defined perforation zones into the measuring gap of 5.0 mm. At the same time, the multiple light transmission sensors monitor all porosity profiles and determines envelope curve and calculate the integrals.

Applications and Advantages

Thus direct feedback into the perforation system makes it possible to compensate any changes in terms of porosity and perforation locations so that each jumbo production roll up to 25,000.00 meters as well single or quadruple bobbin sets can be produced and controlled without intermediate stops and certificated in quantity und quality on their end.

Natural porous or perforated web material as cigarette, tipping, plug-wrap, filter, packaging, non-woven, flees, coated paper as well micro or macro perforated plastic films as BOPP, LDPE, PP, EVA, HDPE, etc. are controllable with the OPSS-1 scanning system.

Optical properties

Material specific wavelength selection between 1200-1800nm, material specific finger prints, molecular spectral properties, transmission grades, optical angle scanning, Lambert Beersche law determining, ultra low level stray scatter light detection, polarization, slot diaphragms, transverse displacements control the light beams along/far from the optical X and Y axes.

Specific information by website links and patent resources.

The former patent application DE19542289 A1 concerns a method and device for optical dynamic, i.e. a non-contact, in-line surface-tension / surface-energy measurement for running substrates whereby the detection can be in the transverse-direction or in the running-direction of the web.

In the context of this invention, running substrates or moved web material is to be especially understood as being plastic films like PE, PP, LDPE, HDPE, BOPP, LLDPE, EVOH, PTFE, PET, PS, PMMA, PBMA, PVC, PA and also laminated or coated film or paper webs which still show a measurable optical transmission in the wavelength range of 1200 to 2200 nm.

A higher material wetting capacity, respectively, a higher material adhesion capacity, which can be achieved by increasing the surface tension, is demanded in many application cases for better printability, coatability or adherence capacity during the manufacture, finishing, printing and processing of running substrate webs.

Described is a method and device for optical dynamic in-line surface-tension measurement in ranges from 30 dyne up to 60 dyne in which a substrate web running vertically through a measuring gap is subjected to a chromatic light transmission from two optical channels displaced by 90° to each other. This light transmission is detectable by two optical detection systems located on the other side of the web.

Material specific wavelength selection, light transmission angle changes, polarisation slot diaphragms and transverse displacements of the light beam feeder along the optical X-axis result in extreme scattering and diffraction of the IR light photons in the boundary layer area on both sides of the sub-nano layer within the substrate web. Their transmitted light intensity enables, after detection and evaluation, the determination of a direct relationship to the absolute surface tension.
And this entirely independent of the material-specific influences like: material and surface consistency, crystallinity, thickness, density, structure, polar grouping, temperature and type of pre-treatment.

Introduction
Non-contact, realtime and in-line operation surface-tension or surface-energy dyne - measuring systems for running webs as like plastic films in general, coatings, laminates etc. does not exist world-wide. Due to the broad application field of surface-treated or surface-non-treated webs of plastic film, non-woven fabric, laminates or coated paper, there is unimaginable market potential here in respect of the in-line process measuring of the surface tension - dyne - and an in-line control of the dyne treatment level and moderate quality control.
