ABSTRACT:
A sanding and polishing machine for individual workpieces having an infeed conveyor for carrying workpieces along a predetermined path through one or more tandemly arranged working stations for exposure to a series of endless abrasive belts. The abrasive belt contacts the workpiece under the influence of a multi-segmented platen, with each platen segment being arranged for adjustable positioning relative to the plane of the surface of the workpiece. Positioning of each individual platen segment is accomplished by virtue of the combination of a workpiece sensor together with an adjustable selected input supplementing the workpiece sensor so that one or more platen segments disposed adjacent to those segments actuated by the workpiece sensing units are also actuated, thus increasing the number of segments responding to the presence of workpieces in the working station and either symmetrically or asymmetrically enhancing the sensed width of the workpiece.
