  • Patent number: 4265409
    Abstract: An apparatus that controls the swinging of a frame (50) and the rotation of a turret (52) in an automatic web rewinding machine. The frame (50) is pivotally mounted in the machine and a turret (52) including a plurality of rotatable mandrel assemblies (56) is mounted for rotation within the frame (50). The control apparatus includes an indexing device (66) having an output shaft (70) that undergoes intermittent rotation in response to continuous rotation of an input shaft (68). One drive means (80), coupled and responsive to the output shaft (70) of the indexing device (66) provides intermittent rotation of the turret (52). A second drive means (78) is provided to control the rotation of the cam (60) in order to minimize the overlap of the rotation of the cam (60) with the dwell time of the turret (52). The optimum condition occurs when the cam (60) rotates only when the turret (52) is indexing and when the cam (60) does not rotate at all while the turret (52) is dwelling.
