Abstract
1,218,901. Slide fasteners. H. WILCKEN. 28 Feb., 1969 [1 March, 1968]; No. 10925/69. Heading E2S. A slide fastener with continuous rows of links in the form of helical springs is formed from a hose of a thermoplastic material of oval cross section provided with notches 2, 3 corresponding to the link spacing. The notches are cut in such a manner that a norrow web 4, having a width fitting into the interior of the hose is formed. The hose is then cut along a helical path with the path of the cut extending transversely through the middle of each of the webs whereby the webs are subdivided into two portions which at both sides form the coupling projections. Two such links of an oppositely directed helical cut may then be interlocked by a conventional slide. The length of the interior of the hose near the said notches is greater than the radial length of the webs. In an embodiment (Figs. 6-8 not shown) the wall thickness of the hose is greater at the side wherein the notches are cut, said notches forming a narrow elongated web 4 (11) extending over a distance which is less than the equidirectionally extending elongated interior of the hose.
