发明名称 Method and device for spacing continuously manufactured zip fasteners in which the connection elements are constituted by a monofilament of meander or spiral form
摘要 The invention relates to a method and a device for spacing continuously manufactured zip fasteners having connection elements constituted by a monofilament of meander or spiral form rigid with the edges of supporting tapes. The method consists in removing by cutting firstly the central part of the connection elements of the two coupled tapes, and then removing the open lateral loops of the meanders or spirals by passing under tension the zone of the coupled tapes from which the central part of the connection elements has been removed, over a deviation member in such a manner that the tapes partly wrap said deviation member.
