专利汇可以提供Manufacture of synthetic resin hose专利检索,专利查询,专利分析的服务。并且PURPOSE:To enable the maintaining of a molding accuracy by always feeding a pressured air with a fixed pressure to the section to the closed portion of an inner hose from the molded end of a hose of raw material and in the section to the closed portion of the inner hose from the takeoff end of a product hose. CONSTITUTION:A resin compound 1 from a molding machine A forms a hose 1a of raw material with dies a1 and a nipple a2, turned to an inner hose 1b being cooled by a cooling water from a nozzle B2 and then to a product hose via a raw material-laminated hose 1e. Pressured air is fed to the section to the closed portion 2 of the inner hose 1b from the molded end of the hose 1a of raw material and the section to the closed portion 2 from the takeoff end of the product hose 1f, from an air supply path a4 of a torpede a2 and an air supply tube j1 of a winding shaft core respectively to maintain the roundness and dimensional accuracy of the inner hose 1b by always actuating a fixed inner pressure thereby enabling uniform wrapping of a reinforced yarn 1c and even covering of a skin 1b.,下面是Manufacture of synthetic resin hose专利的具体信息内容。
