More Information
Summary:An apparatus for transporting magnetic objects (8) has at least one magnetic transport roller (20) mounted to a frame (10) for conveying a ferromagnetic carrier (12), and means for rotating the transport roller. The means comprises a ferromagnetic stator member (62), integrally associated with the transport roller (20), which has a plurality of spatially separated pole teeth (64) each of which has an operably connected coil (66) arranged for producing rotation of the transport roller (20). The transport roller (20) has a magnetic core (22), a first bonding layer (24) at least partially surrounding and bonded to the core (22), a first layer (26) at least partially surrounding and bonded to the first bonding layer (24), a second bonding layer 28 for bonding second layer 30 to the core (20). Second layer (30) comprises a wear and abrasion resistant material. Further, a ferromagnetic web (12) is arranged for movement along the magnetic transport roller (20) for transporting materials thereon.
