  • Molding core for the manufacture of hollow bodies consisting of fiber-reinforced synthetic resin
    Patent number: 4177032
    Abstract: A molding core, consisting of a plurality of flexible metal plates, for the manufacture of cylindrical hollow bodies or wound sections of fiber-reinforced synthetic resin. The metal plates are fixed to support members which in turn are connected to frames. To release the hollow bodies or wound sections, two diametrically opposed metal plates can be tilted inward and the frames can be moved toward one another by means of a common drive. It is possible to assemble a plurality of hollow bodies or wound sections to form vessels of large volume.
