2089746 9203257 PCTABS00010 The invented sander with orbiting platen and abrasive (10) includes a platen (100), an abrasive (152) secured to the platen (100), and a motor (116) connected to the platen (100) to move the platen (100) and abrasive (152) in an orbit or circular pattern. The motor (116) is connected to the platen (100) by a belt (126) that extends around at least one drive shaft (102), where the shaft (102) includes two ends with a step (108) between the ends so that when the shaft (102) is rotated around one end's longitudinal axis (110), the step (108) causes a portion of the shaft (102) and the platen (100) to orbit around that axis (110). The preferred embodiment of the invented sander (10) includes a frame (16), a conveyor (40), first (72) and second (74) drive shafts that support a brace (70) and that cause the brace (70) to move in a first orbit, second (102) and third (104) drive shafts that are supported by the brace (70) and connected to a platen (100) so that when the second (102) and third (104) drive shafts are rotated, the platen (100) moves in a second orbit, and a plurality of neoprene, rubber or synthetic rubber stabilizers (140) positioned between the brace (70) and platen (100). In the invented sander (10), the conveyor (40) feeds a product toward the platen (100) and a rotating brush (180) abrades and polishes the product after it has been sanded by the platen (100).
