Abstract

1462888 Moulding plastic substances HITACHI SHIPBUILDING & ENG CO Ltd 17 June 1974 [24 Aug 1973] 26781/74 Heading B5A [Also in Division F2] A composite pipe comprising a preformed inner core pipe 1 of synthetic resin and a cement mortar layer 28, is continuously produced by moving the preformed pipe 1 through a cylindrical support 6, 17 feeding cement mortar 14 into an annular shaping space 9 defined between the mould part 6 and the pipe 1 to form a cement mortar layer 28 on the outer surface of the pipe 1, and winding a tape 26 on to the outer surface of the cement mortar layer 28 within the support 6, 17. The tape 26 is fed from a reel 23 mounted on rotary member 17 which is mounted on bearings 18 and 19 for rotation on the axis 2 of the mould part 6 and driven by motor 20 through gears 21, 22. The upstream side of the space 9 is closed with annular fins 10 of rubber &c., the downstream side of space 9 is open to provide an annular extrusion port 12. The tape 26, which is preferably air permeable, may be provided on the inner side thereof with projections or spacers (35), Fig. 5 (not shown), whose length is equal to the thickness of the cement mortar layer 28 so as to abut against the outer surface 1a of the inner pipe 1; thus aiding the dimensional stability of the pipe during solidification of the cement mortar layer 28. In the embodiment of Fig. 5 (not shown), water is fed into the space upstream of the fins 10 to further enhance the sealing thereof.
