  • Thin rubber hose and its production method
    Publication number: 20050263937
    Abstract: An impermeable rubber hose is thinned for the purpose of reducing weight and costs. A rigid resin film is used as an intermediate layer. When the resin film is gradually rolled up into a cylindrical shape from a planar shape and fed to an extrusion head and rubber is simultaneously extrusion-molded inside and outside the cylindrical film, the film produces a break or a twist to make extrusion molding difficult. It is an object of the present invention to make simultaneous extrusion molding possible even in such a condition. To attain the above object, a thermoplastic resin film (5) which forms an intermediate layer (2) and of which the melting point is lower than the vulcanizing temperature is formed in a long belt-shape. Slits (7) are provided at fixed intervals on the right and left long side sections (8, 8) of the film (5) in the longitudinal direction.
    Type: Application
