Electrostatic online multiple perforation at cigarette making machines
- OESP-1
former patents: EP 0.460.369 A1 - DE 40.18.209 A1
Patent classification: B 26 F 1/28

Summary description
The ESP technology enables cigarette or tipping paper perforation in
cigarette making processes to reduce nicotine and condensate levels
for non and filter cigarettes.
The electrostatic online multiple perforation process OESP-1 open new
possibilities for cigarette or tipping paper ventilation during
cigarette manufacturing by the fully integration of the electrostatic
perforation equipment/cassettes into the cigarette machine.
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, patented 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
· porosities from 50 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
Advantages for production and cigarette product
All necessary perforation/production parameters are stored and
controlled by microcomputer operation, i.e. geometrical and
synchronized positions of perforation lines, zones etc., pore
densities, 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 control/PLC
system of the 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 online laser
macro/micro perforation processes.
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.
