ABSTRACT:
A sheet-guiding drum for use in printing machines and having gripper links spaced uniformly around the periphery of the drum. Gripper contact strips of the gripper links are adjusted uniformly in order to accommodate different printing material thicknesses. Such adjustment is achieved by the provision of a drive motor in the journal of the drum, the drive motor being connected by a coupling to adjusters which extend radially from the center of the drum. Each adjuster moves a rod axially of the drum and effects radial adjustment of the associated contact strip by virtue of co-acting wedges carried by the rod and the contact strip.
