Abstract

1,124,735. Filter elements. STONE FILTER CO. Inc. 22 July, 1966, No. 33079/66. Heading B1D. End caps 24 of plastics material (examples given) are bonded to annular filter elements by 'spin welding', in which the cap and filter media are relatively rotated in contact to soften the cap by friction and the cap and media are then pushed together to make a seal. In Fig. 4 the filter element comprises an inner layer of pleated, impregnated paper 10, with a loosely woven textile mesh 12 bonded thereto for reinforcement, and layers of felted fibreglass 20 between layers 18, 22 of woven fibreglass, outer layer 22 being helically wound (Fig. 1, not shown). End caps 24 are bonded to this assembly on its end face 40 and inner and outer axial portions covered by flanges 28, 30. Figs. 5, 6 (not shown) illustrate a similar arrangement in which the filter element comprises a helically wound strip of impregnated paper. Cap 24 has a sealing ring 36 and the cap in Fig. 6 has an integral lip for engaging an internal nipple. Other filter media such as perforated metal and woven mesh may be used.
