Multiple online ESP or LASER perforation at cigarette making machines
- OESP-1

Perforation of tipping/cigarette paper webs for filter cigarette
ventilation
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.

IPM - International Perforation Management - ONLINE ESP technology and
former patents EP 0460369 A1 - DE 4018209 A1 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.

To archive that immense ESP demands IPM developed, designed, patent
grant 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 15 µs, 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 MAX-S, MARK-9, Protos 80, etc.
*	porosities from 50 up to 400 C.U.
*	pore densities from 25 up to 300 pores/cm2
*	zone width form 2.0 - 6.0 mm
*	porosity profile in cigarette length, relation 1 : 20
*	hole sizes from 30 up to 80 µm
*	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., 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 control/PLC
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 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.

New ranges of applications will be made accessible as new products
with special features will be developed.
