Title:
METHOD AND APPARATUS FOR MAKING SYNTHETIC RESIN HOSE WITH REINFORCEMENT IMBEDDED THEREIN
Document Type and Number:
Japanese Patent JPS5456660
Kind Code:
A
Abstract:
There is disclosed an apparatus for manufacturing a synthetic resin hose having a tubular reinforcing member embedded therein, which comprises a hollow cylindrical member having diameter adjusting discs provided with yarn guide holes for guiding a plurality of bonding-agent applied warps to the outer peripheral surface of the hollow cylindrical member, and an adjusting disc for guiding braiding yarns to the outer peripheral surface of a tubular member formed by said plurality of warps; a braiding machine surrounding said hollow cylindrical member and weaving the braiding yarns into a braided member; a first heating unit surrounding said hollow cylindrical member and bonding the warp tabular member to the braided member at the contacts therebetween, thereby heat-setting a tubular reinforcing member consisting of the warp tubular member and the braided member; a resin applying unit having manifolds and die for coating synthetic resin to the inner and outer peripheral surfaces of said tubular reinforcing member; a second heating unit for gelation of synthetic resin coated to said reinforcing member; and a cooling unit for air-cooling a composite tubular body thus formed; said member, said machine and said units being arranged in the order described succeedingly from below of the hollow cylindrical member, wherein the following steps are applied thereto: (a) weaving and forming a reinforcing member consisting of a warp tubular member and a braided member, said warp tubular member being formed by guiding a plurality of bonding-agent applied warps through yarn guide holes provided circularly to the outer peripheral surface of a hollow cylindrical member and drawn in the longitudinal axial direction of a hose being formed, and said braided member being formed by weaving braiding yarns on the outer peripheral surface of said warp tubular member; (b) heat-setting said reinforcing member; (c) guiding said reinforcing member to a resin applying unit while cooling said reinforcing member, followed by the coating of a synthetic resin material to the inner and outer surfaces of said reinforcing member; (d) heating the resin-coated tubular member for gelation of the synthetic resin material, thereby embedding the reinforcing member in the synthetic resin material, thus forming a composite tubular body so as to provide a foldable and flat synthetic resin hose applicable to various usages such as fluid transformation hoses for water supply, water drainage, water distribution and waste water treatment in various field such as civil engineering works, construction works, agriculture, engineering and mining.
