  • Patent number: 4671842
    Abstract: A system for the automatic manufacture of pipe-shaped or tubular structural parts of a fiber-reinforced plastic. A device is provided with which fiber strands are soaked with a heat-hardenable binding agent. The device has the capability of clamping at least one winding mandrel into a winding machine, on which mandrel can be placed the soaked fiber strands. The winding machine has a guiding mechanism for the fiber strand which is to be wound onto the mandrel, which guiding mechanism can be moved back and forth parallel with respect to the mandrel. A transporting mechanism is provided for moving the wound structural parts through a hardening furnace to a device for extracting the winding mandrels from the hardened structural parts and to at least one finish-working station. The extracted and now empty winding mandrels are returned through a mandrel preparation station to the winding station. The finish-working station is provided between the hardening furnace and the mandrel extracting device.
