Title: Rubber hose and its manufacturing method
Inventor: BABA HIROKI
IPC: B29C48/32
Filed: 2001-06-14
Abstract: PROBLEM TO BE SOLVED: To provide simultaneous extrusion molding where conventionally extrusion molding was difficult due to bending and twisting of a resin film when an impermeable rubber hose is thinned for the purpose of reducing weight and cost, the resin film of an intermediate layer is stiffened, and rubber is simultaneously provided in an interior and exterior of the resin film by extrusion molding while the resin film is gradually rolled from a planar shape into a cylindrical shape and fed to an extrusion head. SOLUTION: The thermoplastic resin film 5 composing the intermediate layer 2 and having a melting point temperature lower than a vulcanizing temperature is formed into a long band shape, and slits 7 are formed on its right and left long edge parts 8 and 8 in the longitudinal direction at predetermined intervals. Since the long edge parts 8 and 8 are weak parts due to the slits 7 when the resin film 5 is sent into the extrusion head 10 and it is rolled into the cylindrical shape, distortion during bending is absorbed and it can be bent circularly and the right and left long edge parts 8 and 8 are overlapped at an overlap part 6. In this state, the rubber is provided in the interior and exterior by simultaneous extrusion molding, it is vulcanized, the overlap part 6 is welded from above and below, and the slits 7 are eliminated.
