A device for alternate transport of sheet-shaped materials (1) has at least one frictional wheel (41, 42) as well as a housing (20, 21, 22), an actuating element (30), a drive (34) for the actuating element (30), a control (70) for the drive (34) and at least one driven transport element (50, 52), whereby at least one frictional wheel (41, 42) is mounted so that it can rotate at the end of a spring plate (10), whereby the spring plate (10) is mounted with respect to the housing (20, 21, 22) and the actuating element (30) in such a way that the spring plate (10) can be brought into a first active bending state and into a second passive bending state by means of the actuating element (30), whereby in the active bending state the at least one frictional wheel (41, 42) is in working connection with the transport element (50, 52) and in the passive bending state it is not.
