Abstract: A device for the transport of flat, in particular platelike objects (2, 2'), with a driven transport band (4, 4') which revolves around a transport band body (3, 3') and on which the objects (2, 2') come to bear during transport, the transport band being provided with intake orifices capable of being loaded with a vacuum by a vacuum system, in such a way that suspended or horizontal transport of magnetic and nonmagnetic flat, in particular platelike objects at high speeds and accelerations becomes possible, via a combined vacuum-magnetic system.

Abstract: A device is proposed for braking an electrically conducting strip (B), said device being mounted in front of a processing station where the strip (B) under tension undergoes further processing and is provided with a magnetic field generating device (3). The latter generates an alternating magnetic field which induces eddy currents in the strip (B) which in turn exert on the strip a force in a direction against the strip's direction or travel (F). The magnetic field generating device (3) comprises at least one rotating magnetic roller (4, 5) which is aligned transversely in relation to the direction of travel of the strip (B) and is provided around its circumference with magnetic poles (6, 7) of differing polarity in alternating sequence. The direction of rotation (R) of the magnetic roller (4, 5) is opposite to the direction of travel (F) of the strip (B).
