ABSTRACT:
A single housing multi-sander assembly having a drive wheel mounted on a drive shaft, an idler wheel, a ring-shaped housing surrounding the radial drum surface of the drive wheel, an idler wheel mounting assembly, and structure for supporting the idler wheel mounting assembly a predetermined distance from the drive wheel. A closed loop abrasive belt passes around the radial drum surfaces of the respective drive wheel and idler wheel. The ring-shaped housing has a pair of radially spaced split through ways in the radial surface of the ring-shaped housing which function to form a path through which the closed loop abrasive belt passes. The ring-shaped housing has a support land located adjacent each of the split through ways to provide a support surface against which the underside of the closed loop abrasive belt may be pressed during sanding operations. The drive wheel has a lateral disc-shaped support surface upon which an abrasive disc is supported thereby providing the multi-sander assembly with an abrasive disc on its frontal plane in ninety degree contiguity with an abrasive belt transported on its peripheral drum surface.
