Abstract

A method of manufacturing a tube comprises producing a one-piece wall element containing a tube part 10 and a fastening part 11, the fastening part having a contour which corresponds to that of at least one portion of tube part 10, introducing foamable plastics material into tube part 10, winding the wall element helically, making a joint between adjacent turns of the wall element, and allowing the cellular plastics material to set. In a preferred embodiment the wall element is extruded from plastics material through extruder head 41 (Fig. 4, not shown), and the foamable plastics material is introduced into tube part 10 through a feeding tube (42) as the wall element emerges from the extrusion head. If the foamable plastics material is a thermosetting resin, e.g. a phenolic resin, the wall element is helically wound immediately after the cellular material is introduced. If a thermoplastic material such as foamable polyethylene containing a blowing agent is used, the wall element is heated after the wall element has been helically wound, so as to vaporize the blowing agent. Alternatively a mixture may be inserted which reacts in situ to produce a polyurethane foam with an optional integral skin. The helical joint between fastening part 11 and the left hand lower portion of tube part 10 may be made by means of adhesive, or by passing the interconnected wall elements between heating elements to produce a welded joint.
