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 or Lindstroem principle. 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 width or in rows with online or offline by use of slow, fast flow, sealed off, Slab, slow flow 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 online 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 online multiple perforation process open 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 across the strips and circumference of each cigarette, allows problem less perforations on high speed cigarette making machines up to 12,000 as MAX-S, MK9, Protos 80, 90 etc.
