Abstract
524,742. Sliding-clasp fastenings. BOENECKE, A., DAVID, G. C., and ZEDDIES, H. Feb. 6, 1939, No. 3822. Convention date, Feb. 11, 1938. [Class 44] For the simultaneous production of the two stringers of sliding-clasp fasteners a strip of material of suitable cross-section as shown in Fig. 2 is punched out along its middle line to give a series of apertures 6 and is then cut along such line, for instance by a knife wheel 14, so providing the interlocking projections 7 and recesses 8. The two stringers are then given the necessary staggering and pass through a fixed slider 15 where they are inter-engaged and thereafter are wound upon a storage drum from which any desired length can be cut as required. The interlocking recesses 8 are provided by the punched-out apertures 6 extending into hollow beadings 3. The strip may be operated upon directly after leaving the extrusion apparatus by which it is formed.
