Abstract

At the free end of a pivotable arm (1) of an aligning device, two wheels (4, 6) of identical diameters are mounted for independent rotary movement, such wheels being driven by a shaft (2). The wheels (4, 6) are each eccentrically offset from the axis of rotation (2a) of shaft (2) by the same amount (26, 27)and are uniformly spaced about said axis. With respect to a plane running perpendicularly to the axis of rotation (2a) of shaft (2), each wheel (4, 6) is mounted at an acute angle (.alpha.) such that adjacent wheels (4, 6) are arranged in a V-shaped configuration. The eccentrically (26, 27) and the angular position (.alpha.) of the wheels (4, 6) are related such that the contact surface (4b and 6b) of each wheel (4 and 6, respectively) resting on the sheet to be aligned carries out a movement transversely to the sheet-entrance direction (A) and towards the lateral limiting wall (18).
