A method and device for the plasma perforation of tipping paper, wherein a low temperature plasma is generated on the surface of the tipping paper 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.

An apparatus for separating a composite safety glass panel along at least one pre-definable dividing line, wherein the composite safety glass panel has at least one composite film and at least two glass panels, wherein the composite film is arranged between the glass panels and connects the glass panels to each other, the apparatus having at least one separating device for separating the glass panels along the at least one dividing line and at least one heating device for heating the composite film at least along the dividing line. The heating device has at least one laser device having at least multiple adjacently arranged laser beam sources, wherein multiple adjacently arranged individual intensity profiles for heating the composite film at least along a portion of the dividing line can be produced with the laser device. The invention further relates to a method for separating a composite safety glass panel.
