Abstract

1,265,135. Moulding slide fasteners. H. ANDEREGG. 3 June, 1970 [6 June, 1969], No. 26867/70. Heading B5A. [Also in Divisions B3 and E2] A mould for forming a sliding fastener having metal or plastics fastener elements, comprises mould parts 8 and 9 formed with cavities 10 and 11 for the elements which are moulded to a stringer tape 12 located in a recess in the part 9, and a metal tape or strip 22 located in a recess 21 of the part 8, which, together with the tape 12, seals the mould cavities where the stringer tape emerges. The mould is filled from an injection nozzle 15 through passages 13, 14. After moulding the part 8 is lifted from the part 9 by a bolt 16 together with the fastener and tape 22, to be subsequently stripped from the part 8 by ejectors 19. The tape 22 can be formed as an endless belt, Fig. 3, not shown, which after moulding is indexed round rollers 23 in the direction of the arrow shown, or it can be a metal strip placed in position by hand.
