Abstract

1,210,779. Extruding composite tubing. KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 30 Sept., 1969 [1 Oct., 1968], No. 48056/69. Heading B5A. [Also in Division F2] A metal strip is longitudinally disposed about an extruded thermoplastics tube and formed into a slit tube, the slit is then closed by folding or by welding, and the closed slit tube is then enclosed in a sheath of thermoplastics material. In a preferred embodiment, a polyethylene or polyvinyl chloride tube 2 is produced by extruder 1. A plastics tape 3 which becomes adhesive when heated is wrapped around the tube, either longitudinally (as shown) or helically, followed by a metal strip 4, e.g. of copper, aluminium, steel or a metal/plastic laminate, which is wrapped longitudinally. The slit in the metal tube is closed by lap or butt welding under an inert gas atmosphere in welding device 5. A second layer of plastics tape 6 which becomes adhesive when heated is applied, and then a thermoplastics sheath (9, Fig. 2, not shown) is extruded on by extruder 7, the heat of the process causing 2 and 4 to be bonded via tape 3, and 4 and (9) to be bonded via tape 6. Corrugations or grooves may be applied to the metal tube 4 before applying tape 6, or to outer sheath (9).
