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.

A delivery apparatus for use in a sheet-fed printing press, said printing press having inking means for providing an application of ink to a sheet, and having gripper means for gripping a leading edge of said sheet as said sheet exits from said inking means, comprising: a) main wall means having first and second ends and a central axis extending between said ends, said main wall means being arcuate; b) said main wall means having a gap extending between said first and second ends, said gap forming leading and trailing edges on said main wall means; c) leading edge wall means having a trailing edge and a leading edge, said leading edge wall means being located in said gap and being moveably coupled to said main wall means such that said trailing edge of said leading edge wall means is adjacent to said leading edge of said main wall means, said leading edge wall means forming a smaller gap between said leading edge of said leading edge wall means and said trailing edge of said main wall means; d) said main wall means and said leading edge wall means having respective outside surface portions that form an outside surface, said outside surface having a myriad of minute projections projecting radially outward, said projections having rounded outer ends; e) said leading edge wall means being movable between innermost and outermost positions, such that with said leading edge wall means being in said outermost position said leading edge of said leading edge wall means is further away from said central axis than said leading edge of said leading edge wall means when said leading edge wall means is in said innermost position; f) said main wall means being adapted to be rotatably mounted to said press adjacent to the exit of said inking means, said smaller gap being adapted to receive said gripper means when said gripper means grips the leading edge of said sheet, whereby said leading edge wall means is adapted to contact the portion of said sheet adjacent to said sheet leading edge.
