ABSTRACT:
A self-tracking roller comprised of a plurality of individual elements is presented. These elements alternate between evenly distributed idler rings and spacer rings arranged in two groups having a central space therebetween. This central space permits two superimposed dual belts to form a sandwich for conveying solid material therein. Each idler or tracking ring has a conical shaped configuration which acts to urge a conveyor belt thereon toward the center of the roller. The relative dimensions and number of rings may be flexibly varied depending on the application. The result is a self-tracking roller aptly suited for use in conjunction with dual or sandwich conveyor belt systems.
