Abstract
A fastening device for continually taking up slack in a strip of abrasive paper wound helically about a rotatable drum sander. Rotation of the drum sander tends to cause the helical abrasive strip to tighten its wrap about the drum and to cause a linear extension or slack in the strip. The fastening device is spring biased to continually tighten the strip to take up any slack that may develop.
