Abstract
A band sander has a motor housing (2) and a band running case (17) located below the latter, the abrasive band revolving therein. The abrasive band is driven via a belt (17) and belt wheels (14, 16). Because of manufacturing tolerances, it is necessary to be able to adjust the belt tension in a simple manner after the device has already been assembled. This is effected by an insert plate (19) which is inserted into a slot (18) between the motor housing (2) and band running case (7) so as to be displaceable. The insert plate (19) has steps (31 to 33) of varying height which determine the distance between the motor housing (2) and band running case (7) and accordingly determine the belt tension.
