Abstract
1311647 Seaming sheet material KABELUND METALLWERKE GUTEHOFFNUNGSHUTTE AG 19 April 1971 [2 April 1970] 26103/71 Heading B5K [Also in Division F2] A film 1 of synthetic resin material is drawn from a supply reel (not shown) and is then passed through an entrance piece (not shown) which bends it about its longitudinal axis to form a skelped tube with overlapped edges. The tube passes through a guide tube 2 of non- magnetizable material and is drawn off by means (not shown) beyond the guide tube. The overlapped edges are passed beneath a tension roller 9, one edge then passing over a heated wedge 10 and the other edge passing beneath the wedge. A toothed wheel 11 presses the heated edges together to weld the seam and the tube passes through guide tube 2. A support 5 of magnetizable material (e.g. steel) is pivoted upstream of the welding station and provides a base which bears against the wheels 9, 11; the wedge 10; and the inner periphery of the guide tube 2. Magnets 6 provide the force which urges the moveable support 5. A pressure pad (e.g. of felt or P.T.F.E.) presses the upper edge against wedge 10. A plurality of heated wedges 10 may be used, in which case they are preferably independently heated. If an insulated pipe is required a metal pipe may be fed into the film of synthetic resin material and a foamable plastics material introduced between the concentric tubes. The foamable plastics material should preferably be formulated to foam after the weld seam has cooled sufficiently to be no longer plastic. Suitably the plastics film may be P.V.C. and the guide tube 2 may be of copper.
