<p>Apparatus (10) for winding elongate material on a toroidal-shaped article includes an open shuttle (22) rotatably driven on an automatically opened support frame (16) by a plurality of drive roll assemblies (85,87) carried by the frame (16). Each drive roll assembly (85,87) has a drive roll pulley (84). A plurality of belts (192, 191, 190, 188, 186) are provided to drive groups of the drive roll assemblies. Drive rollers contact a groove (115) on the shuttle (22) to provide a positive and responsive power transmission therebetween. The shaft (82) of each drive roll assembly (85,87) is mounted in an eccentric bearing in a web (30) of the support frame (16) to provide adjustment of the position of the drive rollers (92) relative to the shuttle (22) for centering the shuttle (22) relative to the frame (16). A motor and brake set (18) is provided on a base (12) for driving the shuttle (22) through the drive roll assemblies (85,87) at a constant speed of rotation, and for rapidly accelerating, decelerating and braking the rotation of the shuttle (22). An entrance guide (116,117) is provided for the groove (115) of the drive track on the shuttle (22) to guide the traverse of the shuttle (22) across an open segment (38) of the frame (16) between the last drive roller (92) preceding the traverse and the first drive roller (92) after the traverse. </p> |
