Abstract

A sliding clasp fastener comprises a pair of stringer tapes 3 on to each of which is moulded a row of interlocking elements 5 of thermoplastic material formed as continuous strips extruded on to the associated stringer tapes and having interlocking heads, in which each stringer tape is provided with upper and lower rows of the interlocking elements, 4,4 only the heads of which project beyond the edge of the tape, and the gaps between the upper and lower rows are divided by the tape, so that the heads on each tape are supported transversely in the opposing gaps by the faces of the stringer tapes. As shown, fastener elements 5 and a guide strip 11 are extruded on to the edges of open mesh stringer tapes 3 by means of a three part die 11a, 11c, 11b to produce elements along opposite edges of each tape. The die and tapes are passed through an extruder so that the die sections 11a-11c are coated on all sides with thermoplastic material and the material flows into die cavities 12 to form a strip and fastener elements on each tape. In an alternative form, split dies may be used. Specifications 1179921 and 1179923 are referred to.
