ABSTRACT:
A belt and roller system comprising a roller having a permanent magnet sandwiched in between a pair of temporarily magnetic disks with the magnetism of the disks induced by the permanent magnet. Each temporarily magnetic disk may be steel. Each pole of the permanent magnet is disposed adjacent to a pole of one of the temporarily magnetic disks resulting in a magnetic attraction to a disk at each pole of the permanent magnet. The opposing magnetic poles of the disks form a magnetic flux circuit by which a temporarily magnetic belt, such as a steel belt is guidable to prevent or reduce deviation which it may have from its roller path. Additional permanent magnetic rollers or other rollers known in the art may be combined with the magnetic roller of the present invention to form a gear train about which the belt rotates.
