ABSTRACT:
Disposed between magnetic rollers (32) which can be driven in rotation for conveying metal sheets (10) suspended from them and leave gaps (40) free between them, are pushers (44). The pushers (44) can be moved out of a retracted upper position in which they leave the sheets (10) freely suspended on the magnetic rollers (32) into a lower position in which they hold the sheets (10) at a distance below the magnetic rollers (32). The movement of the sheets (10) in the conveying direction (18) of the magnetic rollers (32) is limited by a stop (72). In the lower position, in which they have pushed a sheet (10) off the magnetic rollers (32), the pushers (44) are movable, with the sheet (10), transversely to the conveying direction (18) of the magnetic rollers (32). Disposed laterally beside the magnetic rollers (32) is a withdrawal device (76) which conveys onwards the sheets (10) that have been moved away from the magnetic rollers (32) by the pushers (44). The undersides of the sheets (10) are not touched on the way to the withdrawal device (76) and are consequently protected from damage.
