ABSTRACT:
A method for sealing the cut edges which result when filter material is cut from a zigzag-shaped starting material is provided. The filter material area situated within an outer casing is at least partly interspersed with fine particles which are present therein in an unbound state. A cutter blade separates the filter material, which during the cutting process rests against an anvil, by exerting pressure which acts approximately perpendicularly on the material to be separated. According to the method, the severance cut takes place in an area which shortly prior to carrying out the severance cut has been impregnated with a liquid which is solidifiable under pressure.
