ABSTRACT:
An elongated upright open framework defines a vertical workpiece passageway intermediate the frame sides and ends open toward one end of the frame bottom portion for horizontally receiving workpieces from a laterally disposed feed conveyor. The frame supports a carriage for reciprocation between its ends which is driven by a drive motor and a drive train. Pairs of clamp jaws, disposed at respective end portions of the carriage, are opened and closed by carriage movement to grip and release the respective workpiece end portions as it travels with the carriage. One pair of clamp jaws is moved by cam rollers following a cam groove on inner surfaces of the frame to contact one end portion of the workpiece with rotary cutters disposed above and below the travel path of the carriage as the carriage moves to a workpiece release position. A drive motor operated conveyor discharges the finished workpiece from the frame.
