摘要： When sanding for instance panelled doors in a belt sanding machine it must be prevented that transversely extending parts (16) are sanded since it would be harmful to sand across the direction of the grain of the wood. A machine according to the invention is therefore provided with a combined sensing and control device which in a simple and effective manner will prevent damage caused by the sanding process by controlling the contact of the sanding belt with the workpiece. The device consists of a disc (14, 20) which is mounted on the sanding equipment. The disc (14, 20) protrudes a distance beyond the sanding position of the sanding belt (15), in order that the disc will sense the workpiece when the workpiece is moved under the sanding belt. When the disc (14, 20) rolls across a frame piece (16) the sanding belt (15) is pivoted up above the wood, and when the disc (14, 20) meets a recessed part (18), the sanding belt (15) is pivoted to a non-sanding position.

摘要： An improved sander apparatus having a work surface with a conveyor for translating the workpiece across the work surface, and sanding apparatus positioned above the work surface for sanding grooves in the workpiece parallel to the direction of the movement of the workpiece. The sanding apparatus has a pair of spaced parallel shafts extending transversely to the direction of travel of the workpiece and a plurality of sanding assemblies rotatably supported from the shafts. The sanding assemblies each have a sanding wheel contoured to mate with a groove in the workpiece. A motor is mounted on each sanding assembly to rotate the sanding wheel. A variable length link supports each sanding assembly and can be adjusted to control the position of the sanding wheel with respect to the workpiece.
