PROBLEM TO BE SOLVED: To provide a method for manufacturing a rubber hose, which more certainly prevents the mutual adhesion of unvulcanized rubber hoses without bringing about a marked rise in equipment cost and production cost at the time of vulcanization of the unvulcanized rubber hose, and also to provide the unvulcanized rubber hose. SOLUTION: Rubber layers are extruded on a mandrel A by extruders 1, 3 and 5 and reinforcing layers are formed to the gaps between the rubber layers by braiding machines 2 and 4 to form the unvulcanized rubber hose B of which the outermost layer is the rubber layer. The unvulcanized rubber hose B is irradiated with an electron beam by an electron beam irradiator 7 to semi-vulcanize or vulcanize only the surface part of the hose up to a depth of 0.05-1.0 mm. Thereafter, this unvulcanized rubber hose B' is taken up on a tray 8 and heated by steam in a vulcanizer 9 to vulcanize the whole of the hose. COPYRIGHT: (C)2005,JPO&NCIPI |
