Abstract
A prompter/monitor system for use in combination with wide-belt abrasive surface treating apparatus and including an array of individual axially spaced apart signal generating workpiece sensors operatively positioned across the width of the belt with each sensor creating a signal in response to the presence of a workpiece moving along a segment of the width of the belt. Readout means are provided for receiving signals from each of the sensors, with the readout means including a display responsive to a selected one of the workpiece sensors. A data processor is coupled to the readout for determining the accumulative duration of time during which a workpiece is detected by each sensor, and also determining that certain sensor which has detected the least duration of workpiece presence. The total amount of time for which workpieces are detected for each individual sensor are compared, and the display is actuated to represent those width segments which are being under (or over) utilized.
