Abstract:
Inverter (1) for thin, flat printing substrates (2) in a printing machine, with belts (7, 8) respectively positioned over two deflection pulleys (3, 4, 5, 6) that are together set at 180Â° between the deflection pulleys (3, 4, 5, 6), characterized that, in a transport direction (9), after a setting region (10), at least three guide rolls (11, 12, 13) are mounted on the respective supporting strand side (7â€², 8â€²) of belts (7, 8) in alternating arrangement and said deflection pulleys (3, 4, 5, 6) are equipped with retaining collars (14) on both sides at least where they serve as guide rolls, said retaining collars (14) being freely rotatable relative to said deflection pulleys and guide rolls (3, 4, 5, 6, 11, 12, 13, 18, 24); at least one additional guide roll (18) arranged before the setting region (10); and at least one guide device (19, 20, 21) arranged that guides the printing substrates (2) on at least one outer side (16, 16â€²) to facilitate inversion.
