Patent GB-2005747-A (GB)
Title: Rope stranding machine for layer stranding by the SZ stranding principle
IPC: D07B3/00
Filed: 1978-07-26
Abstract: A machine for SZ stranding pulls wires 1 from fixed pay-out means 9 and feeds them to intermediate store devices 8 before passing them onto cylindrical or conical storage drums 2 rotatably mounted on a stranding tube 3, each drum 2 being drivingly connected to the tube 3 via a take-off arm 4 fixed on the tube 3 and carrying a friction coupling 5 for driving the drum 2, the wire passing from the drum 2 over pulleys 7 and 6 on the arm 4 to the interior of the tube 3. For one direction of rotation of the tube 3, the couplings 5 rotate the drums 2 so as to draw wire from the stores 8. The stranding operation pulls wire off the drums 2 and causes their speed to increase so that they take up more wire than is paid off. When the drums 2 are full the rotation of the tube 3 is reversed and this causes some wire on the drums 2 to be fed back to the stores 8 while the rest is used for stranding, and so on. <IMAGE>

Patent GB-2055620-A (GB)
Title: Improvements in or relating to building panels
IPC: E04F13/08
Filed: 1980-06-18
Abstract: The invention relates to building panels which are prefelted on one major face with a felt material impregnated or saturated with bitumen and wherein the board is made of a material, such as chipboard or flaxboard or plywood which absorbs moisture and water. The faces of the board which are not covered by the felt have a wax coating applied thereto to prevent ingress of moisture and water. Methods and apparatus for manufacturing the panels by a continuous system are described. In one method the felt is made on the board by applying a web of fibrous material to a coating of bitumen applied to one major face of the board, and in another method the felt is made prior to application to the board by passing a web of fibrous material through a tank of molten bitumen and fillers. The wax coating is applied to the major face opposed to the felted face by a roller assembly which transfers molten wax from a bath to the board, and the side edges of the board are coated with the wax by spraying the molten wax. Various alternatives are described, particularly to ensure that the bitumen does not flow onto the side edge faces.
