    Abstract: Apparatus for continuously applying a spiral wrap around successive cylindrical articles, securing the wrap to the cylindrical articles forming a series of wrapped articles, and subsequently severing individual wrapped articles from the wrapped series of same. Cylindrical articles are deposited onto a conveyor belt along which they are fed in proper alignment and in end to end abutting relationship to a wrapping station. At the wrapping station, a covering material, such as paper or the like is spirally applied to the successive rotating cylindrical articles in continuous fashion. Rotary and forwarding motion is supplied by a drive belt acting on previously wrapped articles which motion is imparted to the individual articles at the wrapping station. Subsequent to the wrapping station, the wrap or cover is secured to the cylindrical article by contact heaters, tunnel heaters, adhesive, or the like. The wrapped series of articles is fed to a severing station where cutters operating in timed relationship with movement of the series sever the individual articles therefrom. Cylindrical tubes may also be produced by the instant apparatus by utilizing a cylindrical, rotating mandrel and maintaining the mandrel at the wrapping station. Methods of continuously wrapping cylindrical articles, and producing cylindrical tubes are also disclosed.

    Abstract: A method and apparatus for bending flat thermoplastic laminates into structural shapes such as angles, channels, Z sections, J sections and I sections. In order to bend the laminate into the desired shape by appropriate tooling, heat is applied in a localized manner only to the area that is to be bent. The application of heat is sufficient to heat the laminate to its softening temperature in the bend area, and the plies of the laminate can thus slip in the bend area only as bending force is applied so that the bend can be made without the need to heat the entire laminate to the softening temperature.

    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. Through the aforesaid structure, pipe-shaped or tubular structural parts of any desired shape can be manufactured.
