An apparatus for aligning sheets in a processing machine includes translationally movable stops or front lays which can be driven through the use of a coupler mechanism or individually actuable electric motors.

Apparatus for aligning sheets on stops

A drum for conveying a sheet has a cohesive sheet-guiding surface provided at little effort or cost and includes a drum body, a jacket forming a circumferential surface and a device for fixing the jacket onto the drum body. The jacket is located above a gap formed in the drum body so as to extend parallel to a longitudinal axis. The device for fixing the jacket includes at least one tensioning body that acts on the jacket in the region of the gap and is adjustable in radial direction.

Drum for conveying a sheet

A device for laterally aligning sheets in sheet-processing machines includes a pulling device having a drivable transport roller and a dabber roller mounted on a pivotable lever. A spring system cooperates with the lever for adjusting a pressing force between the rollers. The spring system has a progressive spring characteristic.
