Abstract

608,122. Moulding sealing elements on sliding-clasp fasteners. GOODRICH CO., B. F. May 5, 1944, No. 3045/48. Convention date, Nov. 8, 1943. Divided out of 607,586, [Group XXV]. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 5, 1944.] [Class 87(ii)] A rubber sealing element 27 is moulded on the part 37 of the fastener elements 29 by means of which they are attached to a stringer 31 and a flexible dam 93 is used to prevent rubber flowing between the parts 35 of the fastener elements which are adapted to engage a complementary series of fastener elements to close the fastening. The moulding is carried out in a mould which holds the fastener elements 29 in a recess in the lower part 91 and comprises an upper part 94 and an insert 95 screwed over it after a strip of rubber which is to form the sealing element 27 has been laid along the fastener. A shield 92 covers the parts 35 of the fastener elements. The mould is finally placed in a curing press. The damming action of the dam 93 may be performed by the head of the stringers 31 or by a lead strip which is subsequently removed. Rubber is also moulded over the stringer.
