ABSTRACT:
A method for transporting a sheet on a ferromagnetic transport belt which includes spacing a first switchable retaining device adjacent the ferromagnetic transport belt. The first switchable retaining device is used to position a magnetic retaining element, for example, a permanent magnet, on a sheet that is adjacent the transport belt. The magnet is released from the first switchable retaining device and is fixedly adhered to the transport belt. The sheet, which is caught between the magnet and the transport belt, is fixed to the transport belt and is transported to a second switchable retaining element that removes the magnet. The invention also encompasses a device including a first switchable retaining device that cooperates with the transport belt in the manner described.
