An inverter (1) for thin, flat products (2), especially printing substrates in a printing machine, with belts (7, 8) positioned over two deflection pulleys (3, 4, 5, 6) that are set together at 180° between the deflection pulleys (3, 4, 5, 6). Such inverter is configured so that the product (2) and the belts (7, 8) move precisely in their reference positions. This is achieved by the fact that, in the transport direction (9), after a setting region (10) at least three guide rolls (11, 12, 13) are mounted on the supporting strand sides (7′, 8′) of belts (7, 8) in alternating arrangement and at least one of the guide rolls (11, 12 13) has a retaining collar (14) on at least one side and at least one guide roll (18) is arranged before the setting region (10). Further, at least one guide device (19, 20, 21) is arranged to guide product (2) to facilitate inversion.
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 180° 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 (7′, 8′) 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);
