Beschreibung
Zusammenfassung:	A belt sander (10) includes a mechanism (18,100) to apply and release tension to the roll of sandpaper used in the sander. A release arm (20,120) is rigidly connected to a rotational member (30,132) that is engageable with a support member (50,170) that is operatively connected to the front roller (60) of the sander. The rotational member is designed such that the rotation of the tension release arm creates longitudinal motion of the front roller to apply and remove tension from the endless roll of sandpaper to allow the user to selectively replace the roll of sandpaper.
