ABSTRACT:
An apparatus such as a belt sander including spaced apart rolls and adjustable mounting means for supporting at least one roll. An endless belt is positioned around the rolls and drive means are provided for the rolls and belt. Alignment means including a belt edge engaging means are operatively connected to the roll mounting means, and a resilient force is applied to hold the engaging means against a belt edge as the belt is moved by the drive means. This causes the engaging means to follow variations in the belt edge position, and this movement is transmitted to the mounting means whereby the variations are compensated.
