  • Patent number: 4643783
    Abstract: A machine and method for splicing a new length of linered tape to a length of linered tape being pulled from the machine without interrupting the movement of the tape out of the machine. The tape is pulled along a supply path aligned with an outlet path, a clamp is activated to stop tape movement at an inlet to the outlet path while a path length changing mechanism is activated to shorten the outlet path at the same rate that tape is being pulled from the machine, the length of tape being pulled from the machine is cut between the outlet path and the supply path, the end of another supply path carrying the new supply length of tape is aligned with the outlet path, splicing means splice together liners on the tape ends at the aligned end and inlet, the clamp is released after such splicing, and the outlet path is returned to its normal length.

  • Patent number: 4394010
    Abstract: A sheet feeder for feeding sheets from a stack thereof, which feeder automatically fans or separates the uppermost sheets within the stack to facilitate their feeding. The feeder includes a feed roll brake releasably coupled to a feed roll which brake rotates with the feed roll until a pre-determined force is applied on the brake by a spring that has been compressed by the normal feeding rotation of the feed roll, causing the feed roll to rotate in the opposite direction to the normal feed direction, thereby fanning the uppermost sheets.

  • Patent number: 4256299
    Abstract: A device for sensing the condition of multiple sheets during a feed of paper employing a rotatable drive roll and a rotatable backup roll eccentrically and pivotally mounted with respect to the drive roll. The device utilizes the frictional force that a sheet of paper exerts on the backup roll, as paper is driven by the drive roll through the nip which exists between the drive roll and backup roll, to pivot the backup roll around the drive roll until the backup roll reaches a position where the frictional force of the paper against the backup roll is no longer able to push the backup roll. This position is proportional to the thickness of the paper being fed. The presence of multiple sheets of paper can be detected by an ulterior position of the backup roll due to the increased thickness of the multiple sheets.
