Abstract

The outer surface of a flexible hose is protected during vulcanization by extruding over it a thin sheet of expandible rubber 14. In preferred embodiments the hose is formed by extruding at A an inner tubular layer 11 of rubber e.g. polychloroprene, or acrylonitrile polymer, on to a flexible mandrel 10 applying a lapped or braided reinforcement of metal wire e.g. brass-plated steel wire, or monofilament plastic material 12, then extruding at C over the reinforcement a tubular outer cover of synthetic rubber 13 e.g. polychloroprene or chlorosulphonated polyethylene. Silicone oil or other separating medium is then applied, then a longitudinally extending wire 15 is introduced, through the extruder D which applies the protective sheet 14. If the hose is coiled on a drum for vulcanizing in a steam autoclave E, the expandible sheet is protected by a spirally applied wrapping of woven cotton fabric. After vulcanization the sheet is split by pulling on wire 15, and so removed. Prior to the extrusion steps heat and vacuum may be applied to the hose to remove trapped air or vapour, and after the extrusion steps the hose may be cooled.
