Abstract

Cladding of a cylindrical slim body with an extruded tube of thermoplastic material whose inside dimensions are slightly smaller than the outside dimensions of the body is effected by (a) transversely expanding the tube by applying an internal pressure greater than the external pressure so that the inside dimensions of the tube become slightly greater than the outside dimensions of the body, (b) placing the body in the expanded tube, and (c) releasing the pressure diference between the outer and inner surfaces of the tube so that the tube encloses the body to form a coating fastened firmly to the tube. In addition to cylindrical bodies, bodies with a square, polygonal or profiled cross section can be coated. Bodies of cellular material, e.g. polyurethane foam, can be given an outer protective coating e.g. of polyethylene, providing good mechanical and corrosion resistance.
