Abstract
A tracking system employs a strip of readily magnetizable material adhered to at least one edge of a conveyor belt used with a magnetic roll separator. The magnetic field produced by the head roller of the conveyor belt produces a continuous centering force which acts on the easily magnetized material providing proper tracking for the conveyor belt. The readily magnetizable material can be attached directly to either surface of the belt, have an edge portion of the belt wrapped around it or, in the form of a woven wire mesh, have the belt integrated into it by vulcanization. The strip of material may be continuous or intermittent.
