ABSTRACT:
A fast acting, high response wire takeup device that takes up and releases lengths of wire in response to changes in wire demand or tension required by a coil winder or the like includes two car mounted pulleys movable along straight, parallel paths and yieldably restrained against movement toward one another. Wire is guided to one of the pulleys and away from the other pulley along paths which are at acute angles to the stretch of wire between the pulleys and the moving mass associated with the pulleys is minimal so that relatively large lengths of wire may be rapidly taken up and released as required. Modifications are also disclosed.
The wire demand or tension responsive takeup device is disclosed as part of apparatus for supplying wire to the shuttle spindle of a high speed stator winder, the apparatus further including a wire tensioning device and a powered takeup device operated synchronously with the shuttle spindle.
