Abstract
A magnetic transport system (8) has at least one magnetic transport roller (20) mounted to a frame (10) for conveying a ferromagnetic web (12). 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.
Claims5
A method for transporting magnetic objects, comprising the steps of:
- providing a frame;
- providing at least one transport roller mounted to said frame, said roller comprising a magnetic core;
- a first bonding layer at least partially surrounding and bonded to said core;
- a first layer at least partially surrounding and bonded to said first bonding layer, said first layer comprising a corrosion resistant material;
- a second bonding layer at least partially surrounding and bonded to said first layer;
- a second layer at least partially surrounding and bonded to said second bonding layer, said second layer comprising a wear and abrasion resistant material;
- providing a web comprising a ferromagnetic material for movement about said transport roller;
- providing means for rotating said transport roller so that said web moves along said roller under the influence of a magnetic coupling between said roller and said web;
- providing a reservoir of permanent magnet objects for transport by said web;
- placing said permanent magnet objects into close magnetic proximity of said web;
- rotating said transport roller so as to transport said permanent magnet objects from said reservoir to an upstream station along said web;
- and, removing said objects from said web.
