Description

OESP-1, OLP-1 ventilation for mass products at cigarette makers or packers development with a Chinese firm consortium, uses of IPM laser multiplexer and hollow fibers up to 3,000 mm length, see above patent, designed for 4 or 8 laser perforation lines, sealed-off laser source 400 Watt, 48-64 mm bobbin width, precise perforation round or oval holes from 60-150 microns, porosities from 100 up to 900 C.U., cigarette ventilation levels from 10-80% by twin or quad lines at each bobbin strip side, up to 14,440 holes/s in total, up to 12,000 cpm or 150 m/min.

OESP-1 OLP-1 multiple ventilation of mass products
Electrostatic perforation has been used since 30 years for ventilation of non-filter cigarettes to create a directed and guided air bypass. For this purpose, cigarette paper for some MYO or RYO and almost every kind of filter cigarettes tipping papers are perforated electro statically offline in zones from 2.0?.0mm width or in rows width by uses of sealed-off laser to reduce the harmful substances such as nicotine and condensate down to countries restricted levels. Another effect is the possibility to control the degree of ventilation of cigarettes.

IPM inline technology and former patents EP0460369, DE4018209 enables cigarette tipping paper perforation while cigarette making processes to reduce nicotine and condensate levels for non filter cigarettes. The electrostatic inline multiple perforation process opening now new possibilities for cigarette tipping paper ventilation during cigarette manufacturing by full integration of perforation equipment or cassettes. 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.

Advantages, direct mechanical integration of perforation units, functional interfacing and EMI level in according of international CE conformity, EG, EN, NEC, CCC standards archiving high production efficiencies and controllable ventilation grades on highly automated cigarette machines. Dual IGBT power electronics and multiple perforation performances cross the strips and circumference of each cigarette, allows problem less perforations on high-speed cigarette making machines up to 12,000cpm at MAX-S, MK9, Protos80, Protos90.

Online perforation with patent granted high-speed laser multiplexer, 8 laser lines, 10.6 microns wavelength, Co2 sealed-off e.g. M2<0.9, Coherent ULR-300 Synrad, Hans Laser, output 45 grad divert mirror, centre high-speed spin twin beam splitter up to 1,200rpm/sec., out coupled with flexible waveguide hollow fibers, HCW, HWG, each in lengths up to 3 meters.
