Abstract
The present invention is directed to a sanding device which is adapted to substantially confine for collection dust created by the device during its use. The present sanding device comprises a mounting plate having an upper surface, a lower surface, and one or more apertures penetrating therethrough. A hollow tube sealingly is connected to the mounting plate at its proximal end and is connectable to a source of suction at its distal end. A resilient pad, having an upper surface, a lower surface, and side surfaces, is mounted to the lower surface of the plate at its upper surface. The side pad surfaces are sealed. The pad is characterized by being formed from an open weave fiber skeleton exhibiting openings throughout the entire pad structure. The lower surface of the pad defines a substantially smooth plane. A removable apertured sanding sheet (e.g. screen) is mounted to the lower surface of the pad and is supported thereby in a substantially smooth planar configuration. Use of such sanding device to sand substrates in a dustless manner forms another aspect of the present invention.
