Abstract

1,054,922. Making re-inforced plastic tubes. B.C.M. PLASTIC DEVELOPMENTS Ltd. July 11, 1963 [July 20, 1962], No. 27950/62. Heading F2P. [Also in Division D1] A pipe or tube is made by winding a composite fabric of glass or like fibres helically in layers on a mandrel 11 with the incorporation of molten synthetic resin, the tube then being rendered rigid by heat treatment, removed from the mandrel and cured. The fabric comprises inner and outer layers 1, 2 of side-by-side rovings of glass or like fibre which are fed between rollers 3, 4 together with an intermediate layer of a roving 6 which is fed zig-zag at the nip of the rollers by an eye 10, Fig. 1 (not shown) carried by a member 9 oscillated by levers 7, 8 which are actuated by a crank-pin and follower 12.
