Abstract
A belt sanding apparatus adapted for use in forming patterns of expanded synthetic-resinous materials is provided with a vacuum platen to prevent flutter of a sanding belt, and a self-aligning mechanism for automatically adjusting the position of one belt roller to compensate for variations in the length of a belt over the width of the belt. The belt sander has antifriction bearings supporting each belt roller, a pivotable work table which is supported and guided by guide portions on the belt sander frame over its full travel, and a side gate which opens to allow installation of a sanding belt, and forms a stiffening structural member portion of the belt sander frame when in closed position.
