ABSTRACT:
Apparatus for controlling the working force and relative disposition of the work-contacting surface of a driven endless abrasive belt while in contact with the surface of a workpiece held in a working station. The controlling apparatus includes a rigid belt back-up pad which is normally biased in a direction toward the working station, and linear cams are provided which include inclined relatively movable ramps for movably positioning the belt back-up pad into predetermined spaced relationship to the working station. Also, because of the relatively high forces involved, guides are provided for controlling the movement of the belt back-up pad along axes which are normal to the axis of the working station.
