ABSTRACT:
The invented Sander with Orbiting Platen and Abrasive includes a platen, an abrasive secured to the platen, and a motor connected to the platen to move the platen and abrasive in an orbit or circular pattern. The motor is connected to the platen by a belt that extends around at least one drive shaft, where the shaft includes two ends with a step between the ends so that when the shaft is rotated around one end's longitudinal axis, the step causes a portion of the shaft and the platen to orbit around that axis. The preferred embodiment of the invented sander includes a frame, a conveyor, first and second drive shafts that support a brace and that cause the brace to move in a first orbit, second and third drive shafts that are supported by brace and connected to a platen so that when the second and third drive shafts are rotated, the platen moves in a second orbit, and a plurality of neoprene, rubber or synthetic rubber stabilizers positioned between the brace and platen. In the invented sander the conveyor feeds a product toward the platen and a rotating brush abrades and polishes the product after it has been sanded by the platen.
