Abstract

1486234 Moulding pipe sockets KUBOTA Ltd 1 Nov 1974 [2 Nov 1973 (3) 5 Dec 1973] 47399/74 Heading B5A [Also in Division F2] Apparatus for forming a socket end of a cylindrical pipe of vinyl or polyethylene comprises a thrust taper ring 114 which, when actuated by hydraulic cylinders 113a, 113b, co-operates with segmentally formed collapsible material 117 expanding the latter to force the wall of pipe into a moulding die 115. An annular rigid ring 106 is located by the apparatus in an internal annular groove formed by corresponding groove 115a in the moulding die. In a second embodiment, Fig. 12 (not shown) a non-expansible part-conical member having a greater diameter than that of the non-expanded pipe 100 is forced into the pipe end.
