Embodiment Construction

[0023] The technical solutions of the present invention will be further described below through specific examples.

[0024] figure 1 shows an apparatus according to the invention for the plasma perforation of paper webs, in particular for the plasma perforation of tipping paper webs or tipping papers 4 . An energy source with as small an area as possible is placed on the flat side of the tipping paper 4 . In this example, a needle-shaped electrode 2 is used as an energy source, more precisely to apply a voltage between the two electrodes 2 and 5 . Electrode 2 is mounted on tube 1 . Tube 1 is used to deliver pressurized gas or gas mixture. For better understanding, the airflows in the figure are marked with arrows. There is a nozzle 1.1 at the front end of the pipe 1 for narrowing the air flow. This nozzle 1.1 is mounted at its tip facing the tipping paper 4, concentrically with the electrode 2. Via the cavity 1.2 enclosed by the tube 1 and the spray head 1.1, the pressur...

Abstract

A method and device for the plasma perforation of tipping paper (4), wherein a low temperature plasma (3) is generated on the surface of the tipping paper (4) by briefly ionizing a gas mixture using an energy source that is as close in form to a point as possible, wherein the ionizable gas mixture is locally restricted to a very small surface region of the tipping paper (4).

Description

technical field [0001] The invention relates to a method and a device for plasma punching of tipping paper. Background technique [0002] The five basic parts of an ordinary filter cigarette are the tobacco segment, the cigarette paper wrapping the tobacco segment, the filter tip, the wrapping paper and the tipping paper (tipping paper). [0003] Tipping paper, also known as "tipping paper", is used to wrap the filter tip and wrapping paper. It is the part of a person's lips that touch a filter-tipped cigarette when smoking. In general, the tipping paper will protrude in the longitudinal direction of the filter cigarette, and slightly protrude toward the longitudinal area of ​​the tobacco leaf section, wrapping the cigarette paper and bonding it with the cigarette paper by glue. The filter portion and the tobacco segment portion are mechanically joined together on the machine by the creation of the bond. Tipping paper is mostly actually paper, which can be film or foil. ...
