Abstract

An aligning unit (8) for sheet like material (1), such sheet-like material being aligned by rotation elements (25), (34) with respect to the conveying direction (22) through a machine processing such sheet-like material (1) before the passage to a conveying plane (9). The sheet-like material (1) is contacted, on at least one side, by the rotation elements (25), (34). The rotation elements include segmented rollers respectively having a roller core (38), and a ring-shaped coating (35). The area of contact (36), (44) between the sheet-like material (1) and the segmented rollers (25) is minimized.
