PCT No. PCT/AU94/00544 Sec. 371 Date May 13, 1996 Sec. 102(e) Date May 13, 1996 PCT Filed Sep. 13, 1994 PCT Pub. No. WO95/08012 PCT Pub. Date Mar. 23, 1995Apparatus for twisting a travelling strand includes a rotary structure rotatable about a rotational axis X-X and a series of pulleys mounted on the structure in an array disposed about the rotational axis X-X with each pulley in the series mounted on the structure for rotation about an individual axis of pulley rotation which is generally parallel to the axis X-X and moves around that axis on rotation of the structure. An input strand guide pulley guides an input strand to be twisted onto a path in which it will successively engage the pulleys and a strand exit guide pulley guides the strand from that path into an exit path along the axis X-X. The rotary structure is driven through a drive shaft and the pulleys are rotated by gearing. |
