Abstract

A vertically adjustable gripper support mechanism for the grippers of turning drums of perfecting presses wherein the sheet is turned by two correlatively cooperating gripper systems disposed on cam-controlled pivot shafts biased by return springs. An adjusting shaft is disposed concentrically within the pivot shaft and is rotatable by an adjusting wheel, the adjusting shaft being formed with axially spaced recesses corresponding to the number of gripper supports and having a plurality of arcuate adjusting surfaces preferably offset at 60.degree. in the peripheral direction to one another to provide a multistep vertical adjustment to the gripper support.
