A sheet punching and embossing machine includes revolving gripper cars with which a gripping margin of a sheet is grasped by grippers disposed on the gripper car so as to move the sheet through the machine, a punching station in which the gripping margin can be separated from the sheet, a delivery station in which the gripping margin can be further separated from the sheet, and an ejection station in which the gripping margin can be ejected from the gripper. The ejection station includes a blower which directs a current of air at the gripping margin.

An apparatus for aligning sheet stacks in a feeder of sheet processing machines includes a motor-driven aligning plate and a movement converter situated between a motor drive and the aligning plate. The movement converter forces a movement describing approximately a circular path onto the aligning plate. A vertical speed component of the aligning plate during aligning corresponds to an upward speed of a feeder stack. A method for aligning sheet stacks in a feeder of a sheet processing machine as well as a sheet processing machine, are also provided.
