Abstract

Split mould with channels for trapping segments of two continuous textile tapes with parts of the tapes projecting into twin cavities to be overmoulded by a thermoplastic melt which forms the engagement profiles of the fasteners. Moulded sets of fasteners are ejected and withdrawn as two continuous arrays of fasteners. The mould cavity should be defined by removeable inserts which can be replaced by alternative designs. Integral ejector plates extend beneath the feed web for each track profile. The runners may subsequtnly be used to manipulate the mouldings away from the tool.
