Abstract
An apparatus and technique to guide a fabric conveyor belt by alignment of the fabric weaves with a mating fabric on a vacuum platen is described. The technique functions in a manner similar to an edge guide, however the correcting forces are applied over the surface of the belt as opposed to the edge of the belt. Robust tracking can be achieved and the need for frequent adjustments of the conveyor rollers by the user is eliminated.
