ABSTRACT:
A rotary drum sander is provided with a horizontal boom orienting a rotatable cylindrical drum to cover the spirally wound strip of abrasive material above a work supporting platen. The abrasive material is affixed to the drum by a first and second anchor, the second anchor is pivotally mounted relative to the drum and rotatably biased by a spring to cause the second anchor to rotate relative to the drum to maintain tension in the abrasive strip as the abrasive strip stretches during use.
