ABSTRACT:
A machine for winding of fibres, especially as a circumferential reinforcement to a pipe extrudate in an extrusion channel, which comprises an open ended hollow rotating fibre carrier and guide around the object, the carrier being adapted for the accumulation of turns of fibre on its outside, the guide being adapted to lead the fibre from the turns accumulated on the outside of the hollow carrier inwardly to the object and, means adapted to rotate the carrier with the guide wherein the outside of the carrier comprises fibre support means adapted for the easy rotation of the accumulated turns of fibre relative to the carrier, and further comprising a stationary fibre bank for supplying the carrier with fibre, means adapted to reverse the direction of rotation of the carrier and buffer means intermediate between the carrier and the fibre bank adapted to temporarily take up turns from the carrier during reverse rotation. The buffer means is preferably a second, concentric outer hollow carrier also adapted for easy rotation of accumulated turns of fibre. A reciprocable clamp batten is disclosed to clamp fibre at the object at the moment of reversal of rotation . A lip gasket is described to provide for admission of the fibre to the extrusion channel.
