Abstract
1408844 Pipe couplings ROLLMAPLAST AG 6 Feb 1973 [8 Feb 1972] 5739/73 Heading F2G A sheathed resistance wire 6 is welded in place (e.g. during injection moulding of saddle portion 2) on the underside of saddle portion 2, of a branch pipe connection, to act as welding means for uniting the thermoplastic material of the saddle to that of the main pipe, to which connection is to be made. The saddle may include two identical saddle portions 2. One of the terminals of the wire (7, Fig. 6, not shown) of one of the portions, may be drilled out in making the connection. Instead of coiling the sheathed wire directly in the injection mould for the portion 2, the sheathed wire may be premoulded into the surface of a curved or flat carrier plate and the assembly then placed in the injection mould.
