  • Sheet handling apparatus
    Patent number: 6253899
    Abstract: A sheet handling apparatus, such as a banknote stacker, comprises a carriage (23) that collects sheets by gripping their leading edges with jaws (35, 36) and transports them to a stack (6). The carriage (23) has a pair of driven wheels (32, 34) that push back the stack (6) so that the new sheet can be deposited. The wheels (32, 34) are driven so that their points of contact with the top sheet in the stack (6) have zero velocity relative to the top sheet of the stack (6). Thus, the top sheet in the stack (6) is not crumpled as the carriage (23) passes over the top of the stack (6).
