Abstract

A feeder unit for a sheet-processing machine having a plurality of processing units is provided. The feeder unit includes a feeder, a feed table, and a feed drum. The feed drum is double-sized or larger in that it has a diameter at least twice that of the diameter of the plate or blanket cylinder of at least one of the processing units of the sheet-processing machine. The feed drum includes at least two gripper systems distributed symmetrically on a periphery of the feed drum. The feed drum is arranged with its rotational axis on or offset vertically above a horizontal plane formed by the rotational axes of the printing cylinders in the processing units. Each gripper system is pivotally supported on the feed drum and includes a gripper shaft, at least one gripper arranged on the gripper shaft, a gripper stop bar associated with the gripper, and a front guide arranged on the gripper stop bar.
