  • Loading apparatus for an unwinder
    Patent number: 5709354
    Abstract: A loading apparatus for transferring a first roll from a preparation apparatus to an unwinding apparatus. The preparation apparatus includes a shaft onto which a first roll is loaded, and supports connected to a vacuum source to maintain the web wound about a circulation loop. When a second roll loaded on the unwinding apparatus is expired, the preparation apparatus is rotated about an axis to register the preparation apparatus' shaft with the unwinding apparatus' shaft, and the first roll is then transferred from the preparation apparatus' shaft to the unwinding apparatus' shaft. The ends of the first and second rolls are attached.
