Abstract
A belt wear optimizing system for a wood surface treating apparatus with a plurality of individual work stations arranged serially along an endless conveyor. Each station includes a working abrasive head along with an elevation control for adjustably positioning the contact surface of each abrasive head at a desired working distance from the opposed surface of the workpiece traveling along the endless conveyor. An incoming workpiece thickness detector is positioned at the infeed end, and additional workpiece thickness detectors are positioned downstream from each work station, with each being positioned to measure the thickness of the workpiece after it has passed through its preceding individual work station. In addition to a workpiece thickness detector at the infeed end, a signal generated by the thickness detector is transmitted to a central processor whereupon the head elevation control is actuated responsively to controllably and adjustably position the working head to its desired working position based upon a predetermined stock removal program for each individual head in the sequence.
