Perforation of tipping and cigarette paper webs for ventilation of filter cigarettes
The electrostatic ESP perforation has been used more then 25 years for ventilation of non filter or filter cigarettes to create a directed and guided air bypass. For this purpose, cigarette paper for some non filter cigarettes and almost every kind of filter cigarettes tipping papers are perforated electro-statically ESP OFFLINE and in zones from 2.0 – 6.0 mm width or rows ONLINE or OFFLINE by the use of lasers in order to reduce the harmful substances such as nicotine and condensate down to allowed values. Another effect is the possibility of guiding and controlling the degree of ventilation of the Cigarettes.
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.
Optical online permeability or porosity 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.
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/controlled without intermediate stops and certificated in quantity und quality on their end.
Future prospects
The electrostatic ESP nano or micro perforation usually applies within ranges of the refinement of fine paper, packaging webs, bonded fabrics, non woven, filter paper, bag or force paper as well as special paper webs of most diverse kind especially when additionally treating course materials for achieving special characteristics which for physical or process reasons cannot be achieved by other process technologies.
Our highly modern, industrially approved ESP perforation technology operation which even can be relied on when operated 24/7 can be integrated into existing rewinding course devices or other course devices. Also, they can be used as completely independent perforation devices.
New ranges of applications will be made accessible as new products with special features will be developed.

Multiple online ventilation at cigarette making machines OLP-1
Perforation of tipping or cigarette paper webs for filter cigarette ventilation
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 carbon 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.
IPM – International Perforation Management – ONLINE ESP technology and former
patents EP0460369, DE4018209 enables cigarette/tipping paper perforation while
cigarette making processes to reduce nicotine/condensate levels for non-filter
cigarettes. The electrostatic online multiple perforation process OESP-1 open
new possibilities for cigarette/tipping paper ventilation during cigarette
manufacturing by full integration of perforation equipment/cassettes.
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.
To archive that immense ESP demands IPM developed, designed, patent grand new electronic perforation circuits which working as upward converters with IGBT, MOSFET or HVFET for power pulses from 1 up to 15 micro seconds, high current peaks up to 300 Amps, base frequencies up to 200 KHz on ferrite transformers to generate the special high voltage peaks into the shielded sparking case cassettes.
Advantages of cigarette manufacturing
Small all-over-dimensions, direct mechanical integration of perforation units, their functional interfacing and accepted EMI level in order international standards archiving high production efficiencies and controllable ventilation grades on highly automated cigarette machines.
Powerful dual IGBT electronics and multiple perforation performances across the web, here the circumference of each cigarette, allows problem less perforations on high-speed cigarette making machines up to 12.000 cpm as MAXS, MK9, Protos 80, 90, etc.
porosities from 50 up to 600 C.U. pore densities from 25 up to 300 pores/cm2 zone width 2.0–6.0 mm porosity profile in cigarette length with relations up to 1:20 hole sizes from 30 up to 80 microns cigarette ventilation grades up to 70 %are archive able
Advantages for production and cigarette product
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. All necessary perforation, production parameters are stored and controlled by microcomputer operation, i.e. geometrical and synchronized positions of perforation lines, zones, etc., pores 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 across the cigarette paper web for non-filter or tipping paper web for filter cigarettes are possible. All stored parameter sets are interfaced to the computer PLC control system at cigarette machine. Online insertion of different positions of across areas and porosities of each cigarette brand are very flexible to define and controllable during perforation process. Air ventilation level through the cigarette can be 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 on-line laser macro, micro perforation processes.
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
An online porosity control system OPSS-1 monitor continuously the air permeability, called optical online porosimeter, with a state-of-the-art technology to obtain a close-loop feed-back to the perforation unit to keep the 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.
New ranges of applications will be made accessible as new products with special features will be developed.

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.
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.

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, inline 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, 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 dyn up to 60 dyn 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.

CONCLUSION
Described is a
method and device for opto-dynamic in-line surface-tension measurement in which
a substrate web running vertically through a measuring gap is subjected to a
chromatic light transmission from two opto-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
