Abstract

Vehicle air filter cartridge comprises a cylindrical folded paper element, opt. reinforced with inner and outer perforated metal tubes, and top and/or bottom members made of fusible material, e.g. PVC, which form a strong bond with the element and reinforcements, and which may be reinforced with rigid metal discs. In assembling the filter, the whole structure is placed between two half-moulds, with rigid metal annular disc, pref. of Al or other electrically conductive material, on the outside of the top or bottom member. The disc is subjected to an alternating magnetic field to produce Foucault currents which raise its temp., thus softening the fusible material and swelling the jointing material; the latter is pushed towards the outside of the mould cavity, and the disc is pressed to form the bond between element and top or bottom member.
