ABSTRACT:
Apparatus for cross abrading a workpiece of wood or the like to create a rough-sawn effect across the grain of the wood. The apparatus employs a continuously operating endless abrasive belt that moves relative to a predetermined work area. The workpiece is moved through the work area by a plurality of drive and press rollers generally perpendicularly to the line of endless belt movement. To preclude the abraded rough-sawn effect from being oblique on the workpiece surface, the apparatus includes an oblique platen having a narrow land surface that causes the endless abrasive belt to engage the workpiece over a narrow region of contact. The obliqueness of the platen limits the effect of any given abrasive particle to the narrow region of contact, thus creating cross abrading which is generally perpendiular to the line of workpiece movement.
