ABSTRACT:
A belt sanding apparatus has an endless abrasive belt trained over both a drive and a driven roll for finishing a workpiece, the rolls being mounted on the apparatus frame for rotation about fixed upstanding axes. A side and/or end workpiece support table is mounted on the frame for four-way adjustment relative to the belt. An elongated support bracket plate is provided for mounting each table to the frame for pivotal movement about a transverse tilt axis. Guide rods on the table engage the bracket plate for vertical sliding movement and for effecting pivotal movement of the table about the transverse tilt axis. A turnscrew or the like is provided on the bracket for vertically moving the table relative to the belt, the table being connected to the guide rods for moving the table both along a horizontal plane toward and away from the belt and about a longitudinal roll axis, such that the table is capable of vertical, horizontal, tilt and roll adjustments relative to the belt.
