  • Patent number: 5088404
    Abstract: A delivery apparatus which minimizes marring of wet ink is provided with an arcuate main wall and a gap forming leading and trailing edges. The leading edge can be positioned, either temporarily for adjustable versions, or permanently for nonadjustable versions, radially inward to shorten the path of a sheet exiting the last set of blanket and impression cylinders in a printing press. By shortening the sheet path, marring of wet ink against the delivery apparatus is reduced. The delivery apparatus is mounted onto a gripper bar sprocket shaft such that the gap receives the respective gripper bar. As the shaft rotates to move the gripper bar, the delivery apparatus also rotates. The outside surface of the delivery apparatus has a myriad of minute projections with rounded outer ends and being of a uniform height, which outer surface contact the wet ink side of the sheet.
