Abstract

1,026,223. Seaming non-metallic sheet material. SIEMENS & HALSKE A.G. Sept. 24, 1964 [Sept. 27, 1963], No. 38897/64. Heading B5K. Surfaces composed of thermoplastic synthetic material are welded together by inserting between the surfaces to be united at least one strip 1 of thermoplastic synthetic material which will heat weld to the surfaces and which contains an electrical heating element 2 in the form of an electrically-insulated conductor, and applying an electric current to the element 2 whilst pressing the surfaces into contact with the strip 1 so that the surfaces and the strip 1 become welded together. The invention is applicable to the joining of polyethylene cable fittings and sheaths by means of a polyethylene strip 1. The element 2 comprises a 5 mm. diameter electrically-conductive wire 2 shaped as a planar S-coil having a convolution opening dimension axially of the coil of between 1 and 1À5 times the wire diameter. The wire 2 is electrically insulated to avoid short-circuits occurring across the convolutions thereof or, when more than one strip 1 is employed, across the convolutions of adjacent strips. This insulation must be heat resistant. Varnished copper wire is specified.
