摘要： A device for cleaning abrasive surfaces used in wood sanding operations includes a frame attached to the frame of a belt sanding machine. A retainer assembly is carried by the frame and receives a block of natural or synthetic rubber cleaning material. The retainer assembly and associated block are selectively moved into position whereby abrasive contact of the block with a running belt for cleaning is achieved. The movement of the cartridge assembly is controlled by a fluid cylinder arrangement. Hydraulic withdrawal cylinders at either end of the frame are set to lift the cartridge assembly and block in an upward direction out of a contact position with the sanding belt. A central fluid projection cylinder is used to overcome the upward force of the two outer cylinders, for forcing the block into operative contact with the belt when desired. Controls are provided for regulating contact time with the belt depending on operating conditions. Alternative controls may also be used to adjust the pressure in the cylinders to compensate for the changing weight of the block as it is worn away during use.
