  • Patent number: 4798350
    Abstract: A paper web rewind device includes a rewind turret having circumferentially spaced support members with end chucks for rotatably supporting tubular cores on which a web is rewound. Each set of supports is separately rotated and the turret is rotated to locate one core at a rewind station and the second core at an unload/load station. A rider roll at the rewind station is pivotally mounted and moves upwardly onto the core and then outwardly as the roll diameter increases. Just prior to completion of a rewound roll, the turret rotates and moves the rewinding roll while continuing to wind web thereon and also moves a new core to the loading station with rider roll moved to engage the new core. The moving web engages the new core which is rotated at winding speed. A sensor senses the turret position and is operable to decrease the winding speed of the wound roll to create a slack loop between the new core and the wound roll.
