Patent number: 5544583Abstract: A delivery interrupt mechanism for a printing machine includes a support frame having a stationary guide defining a guide path. A flexible finger is slidably supported by the guide for movement along a curved portion of the guide path while substantially conforming in shape to the curved portion between a retracted position and an extended position in which the finger extends from the frame to support leading edges of printed sheets in a printing machine. The finger is connected to a rotatable input shaft mounted on the frame so that the finger is moved along the curved portion of the guide path between its retracted and extended positions when the input shaft is rotated.Type: GrantFiled: June 8, 1995Date of Patent: August 13, 1996Assignee: A.B. Dick CompanyInventor: Ronald A. Banike

Patent number: 5484255Abstract: A collating machine for stacking sheets of paper fed seriatim thereto from a singulating feeder comprises a deck including a stacking area and a plurality of upper, endless, elastic belts, each of the belts moving around a pair of upstream and downstream pulleys suspended above the deck. A plurality of ramp guide blocks are adjustably secured to the deck between the pairs of pulleys, wherein a lower reach of each of the belts is lower than the highest section of the ramp guide blocks. There is structure for stopping each of the sheets at a downstream end of the stacking area which is a section of the deck between the stopping structure and the ramp guide block. Feeding structure is situated upstream from the pulleys for feeding each of the sheets over the ramp guide blocks toward the stacking area until a trail edge of the sheet moves from control of the feeding structure, wherein the belts convey the sheet to the stopping structure.Type: GrantFiled: April 18, 1994Date of Patent: January 16, 1996Assignee: Pitney Bowes Inc.Inventor: Kenneth W. Lowell

Patent number: 5263705Abstract: A document registration apparatus for use in a document inserting station or a document queuing station is provided. The apparatus includes a document registration unit having a plurality of laterally-spaced registration stops which pivot about a horizontal axis for stopping motion of a document and registering a particular edge of a document to a particular direction in the apparatus. There is at least one urge roller for moving the registered document away from the apparatus for further processing. The document registration apparatus also includes structure for pivoting the documentation registration unit about a vertical axis for skew adjustment of the registration unit.Type: GrantFiled: June 29, 1992Date of Patent: November 23, 1993Assignee: Pitney Bowes Inc.Inventor: Roderick N. Schmaling
