Abstract

A device for laterally aligning sheets in a printing machine can have a feeding table via which the sheets are stream-fed to front lays, and a corresponding side-pull device for laterally moving the sheets after having been aligned at the front lays. The side-pull device can operate by admitting a suction to the sheets, and when moving heavy sheets, e.g. cardboard, at high machine speeds, a pull roller can supplement the suction air by pressing the sheets onto the side-pull device.
