Patent ID: 8016223

Claim:
A process for automatically and sequentially moving rolls of tissue wound on cores, such cores defining a central axis, from a core plugging station to an unwinding station and for sequentially moving spent rolls of tissue from the unwinding station back to a spent core station comprising the steps of sequentially: (a) feeding unplugged rolls of tissue wound on cores to a core plugging station; (b) aligning a first core plug with one end of the roll of tissue and a second core plug with the opposed end of the roll of tissue such opposed core plugs defining a centerline between them, such aligning including the steps of vertically aligning the central axis of the core with the first and second core plugs, horizontally aligning the central axis of the core with the first and second core plugs, and as a final step, angularly rotating the roll of wound tissue to align the central axis of the core with the centerline defined by the first and second core plugs; (c) inserting the core plugs into the opposed ends of the core of the roll of wound tissue; (d) feeding the plugged roll of wound tissue to an unwinding station; (e) removing a spent roll of wound tissue from the unwinding station; and (f) removing the core plugs from the spent roll of tissue; and (g) feeding the spent roll of tissue to a spent core station.
