A sheet processing machine with a transfer mechanism for moving sheets along a handling direction of the sheet processing machine and with a waste evacuation device () for releasing the sheets. The transport mechanism comprises at least one sheet handling element () for moving a sheet. The waste evacuation device () further comprises a passage () formed between an opening surface () and a restraint surface (). The at least one sheet handling element () comprises a first sliding element () and a second sliding element () being in contact with the opening surface () and the restraint surface (), respectively, when passing the waste evacuation device ().

Sheet processing machine

The invention relates to a gripper bar body for a gripper bar in a gripper carriage arrangement in a machine for treating sheet material, the gripper bar body being configured to carry gripper brackets for movement between sheet gripping and sheet releasing positions. The gripper bar body is formed as a hollow structure comprising at least two different materials, the two different materials comprising at least a metal material and a composite material and the at least two different materials being at least partly arranged in a superposed manner. The resulting bar has a better resistance to wear than the ones of the state-of-the-art.
