Abstract
An apparatus for fixing a cap (8) coated with a hot-melt adhesive on an end surface of a filter element (6), comprising a pair of vertical heating units (18, 19) installed in position (A) and an adjacent pair of vertical cooling units (20, 21) installed in position (B). The heating units (18, 19) comprises a pair of heaters (25, 29), each displaceable close to and away from the other so as to nip and release a pot assembly (9) accommodating the filter element (6) to be treated therebetween. The cooling units (20, 21) comprises a pair of coolers (30, 31) subjected to a similar movement. First, the pot assembly (9) occupies position (A) and is subjected to a heat treatment by the nip of the heaters (25, 29), causing melting of the hot-melt adhesive of the cap (8), and then transported to position (B) and subjected to a cooling treatment by the nip of the coolers (30, 31), causing solidification of the molten adhesive.
