The device has a driven transport element (41) arranged on a side of a sheet transport plane (E) and provided with a moved contact surface. A pressing element (42) is arranged opposite to the transport element and on another side of the plane for pressing a sheet on a contact surface, where the sheet is made of paper, cardboard- or plastic material. The pressing element is designed as a radially pretensioned running tape-shaped element e.g. belt and chain. The tape-shaped element comprises multiple links, which are connected with each other, and springs are arranged between the links. The transport element is designed as a transport roller, a conveyor belt and a conveying roller.
