Abstract: By, according to the invention, manufacturing a filter cloth (5, 6) especially to be used in filtering of gas flows, which filter is manufactured in a rolling mill where the individual layers are laminated with a membrane layer (1), to which by the use of a binder (2), such as thermoplastic sheeting, is glued a filter layer (4) with at least one metal layer (3, 13). Hereby is achieved a robust laminate (5, 6), which is, in addition, easy to manufacture in a rolling mill with heated rollers for melting of the binder (2).

Abstract: The invention relates to a method of manufacturing a filter element for use in connection with e.g.

Abstract: Filter cartridge for insertion in a cartridge opening in a plate, where the filter cartridge includes a predominantly cylindrical filter and an outer, annular collar which is made of an elastomer or rubber, which seals against the predominantly cylindrical filter, and where the annular collar has a flange which, when the collar is inserted, lies up against a first side of the plate with the cartridge opening. The filter cartridge also includes an expansion part which is configured to be inserted in the outer annular collar, in that the expansion part is inserted into the collar in the axial direction from that side on which the flange is disposed, and that the expansion part is made of a material which is relatively stiff in comparison to the collar, and includes a first ridge and a second ridge which, when the expansion part is inserted in the collar, lies opposite the first side of the plate in which the cartridge opening is provided.
