ABSTRACT:
A sanding device having a sanding block wherein sheets of sandpaper can be easily and firmly mounted upon or readily detached from the block merely by inserting inwardly bent end tabs of the paper into slots in opposite end surfaces of the block. The top and bottom surfaces of the block are flat and of isosceles trapezoidal configuration with the opposed end surfaces of the block convergently inclined toward each other at an angle of about 84.degree. to the longitudinal centerline of the block. Slots cut into the end surfaces closely adjacent the bottom and top surfaces of the block receive bent-in ends of the piece of sandpaper, the slight angle of the end surface to the direction of sanding creating a transverse force on the paper tending to shift the paper transversely toward the longer of the longitudinal sides of the block. The paper may be folded along crease lines congruent with the opposite end edges of the block, but preferably is heated and bent along the crease lines to permanently set the end tabs. Resilient pads are mounted on the top and bottom of the block.
