Abstract

1,179,923. Extruding sliding clasp fasteners. OPTI-HOLDING A.G. 22 Feb., 1967 [5 March, 1966 (2)], No. 8414/67. Heading B5A. [Also in Division E2] A fastener comprises two stringer tapes to each of which is secured an extruded strip formed with heads and recesses which interlock with their counterparts in the other strip and means are provided to prevent lateral movement of the interlocking elements normal to the plane of the fastener. The fasteners are made by a process comprising feeding a die strip 23 through an extrusion head 22, to completely sheath the strip in plastics material 24, cooling the formed strip, paring away excess material to expose the strip 23, and then removing the strip to leave an extruded sliding clasp fastener strip with interlocking heads protruding therefrom, Figs. 1, 15 (not shown). The die strip 23 is formed from dies to comprise a strip having both edges containing open dies in the required shape of the interlocking heads. Stringer tapes (39), Fig. 15, are fed into the head 22 with the strip so that the rows of interlocking heads become interlocked thereto during extrusion. Rolls 41 ensure consolidation of the extruded material and total filling of the dies. Alternatively, only a strip or strips of interlocking heads may be formed, which is or are subsequently bonded to stringers. In either case only one strip may be formed if the die strip has only one edge formed with dies. The heads may be formed with undercut recesses (10), Figs. 1, 2 (not shown), or strips (12), Fig. 3 (not shown), may extend longitudinally of the head carrying edge of the fastener to cover gaps (9) in which opposed heads lock when closed. The die strip 23 may comprise an endless belt.
