Abstract: A manual stock stop is diclosed including a track assembly and a sliding stop assembly. A cable-activated electromechanical position transducer sends an electrical signal corresponding to the position of a stop bar mounted on the top assembly to a monitor/control unit which displays the position of the stop bar. A fine adjustment mechanism in the stop assembly allows for precise positioning of the stop bar. An automatic stock stop is also disclosed including a track and sliding carriage assembly. A motorized screw mechanism mounted on the track moves a carriage a limited distance along the track. The ends of flippers mounted on the carriage can be extended beyond an edge of the carriage to actually stop the stock. A guide and a device for performing a machine operation on the stock may also be mounted on the track. A computer control unit activates and coordinates the various functions of the stock stop.
