ABSTRACT:
A soft sanding roller apparatus is provided with a soft compressible sanding sleeve and roller that allows a wide flat to form on the side of the sanding sleeve being pushed against a substrate, such as a piece of wood. The preferred sleeve is backed by a soft deformable layer, such as a soft foam layer, which allows the sanding sleeve to conform to the surface of the substrate without chattering or digging into the substrate. The sleeve has a bore diameter smaller than the uncompressed diameter of the soft foam layer so that the foam layer exerts an even force on the cylindrical sleeve to retain its cylindrical shape. The sleeve is driven by a connection such as a one-way clutch between the sanding sleeve and the foam layer on the roller. The roller is rotated in one direction by a motor to do sanding with the one-way clutch driving the sleeve. The sleeve is removed by turning it in a direction opposite to the sanding direction and pulling it axially against the force from the compressed foam layer.
