Abstract
808,476. Moulding caps on tube ends. FRAM CORPORATION. Sept. 30, 1957 [May 22, 1957], No. 30527/57. Class 87(2). [Also in Group XXVIII] Moulded annular end caps 14, 15 only one of which is shown of plastic material in which are embedded the ends of a tubular filter element 12 having longitudinally extending pleats and also the ends of inner and outer supporting screens 11, 13 are formed by providing at the bottom of a mould pan 17 a rib 19 and spaced lugs 18, 20 (not shown) on which rest the adjacent ends of the pleated tube and the supporting screens which are thereby spaced from the bottom of the pan, and the plastic is thus allowed to almost completely embed said ends. The tubular element may be of oval cross section in which case extra ribs spaced round the mould pan serve to assist locating the outer supporting screen. Specification 751,655 [Group XXVIII] is referred to.
