摘要： A spool winding assembly for winding a composite strip onto a spool having a hub is disclosed. The strip (10) it winds includes an elongate plastic strip having a flat base portion and a plurality of laterally spaced apart lengthwise extending rib portions upstanding from the base portion; and a plurality of elongate reinforcing members extending lengthwise within respective rib portions, the rib portions and the reinforcing members forming composite ribs. The assembly includes: a main frame (202); a spool holder (204) for rotatably supporting the spool relative to the main frame; a spool drive unit 206 for driving the spool (50) with respect to the main frame (202); a carriage (240) mounted for lateral movement with respect to the spool (50); a bender (90) mounted to the carriage (240) for receiving the strip (10) as it is fed towards the hub (55) of the spool (50) and for deforming the strip (10) to give it a curved base portion; and a bender drive unit (210) operably connected to the bender (90) for driving the strip (10) through the bender (90).

摘要： A composite strip (10) windable to form a helical pipe is disclosed. The composite strip (10) comprises: an elongate plastic strip (11) having a base portion (12) and at least one lengthwise extending rib portion (20) upstanding from the base portion (12); and an elongate reinforcing strip (30) extending lengthwise and supported laterally by the rib portion (20), the reinforcing strip (30) having a height to thickness ratio of at least three to one and orientated substantially perpendicular to the base portion (12). When wound into a helical pipe, the reinforcing strip (30) reinforces the pipe against radial crushing loads. A bead (40) seals the reinforcing strip (30) from the environment. Desirably the composite strip (10) further comprises: a planar lamina (50) extending lengthwise and bonded to the base portion (12), the lamina (50) having a higher Young’s modulus and strength than those of the plastic strip (11). The lamina (50) greatly improves the pressure rating of a pipe wound from the strip (10).

摘要： An apparatus and method for lining an underground conduit is disclosed. The apparatus (10) comprises: an annular frame (40) having a crown portion (42) and a base portion (49); a strip guide disposed around and supported by the annular frame (40), the guide arranged to guide a strip (12) around a helical path; a pair of strip pinch rollers mounted to the frame (40) at a position circumf erentially about halfway between the crown portion (42) and the base portion (49); a drive assembly mounted to the frame for driving the strip (12) downwards into the helical path in a winding direction so as to present an incoming first edge to an adjacent second edge of a wound convolution of the strip; a liquid remover mounted to the frame, the liquid remover arranged to prevent liquid that has adhered to and ascended with the second edge from descending down towards the incoming first edge; and an extruder (80) mounted to the frame (40) for extruding a molten bead of plastic onto the strip (12) at a position just before said overlap.
