ABSTRACT:
A machine for automatically loading elongated bars into an automatic screw machine. Each bar initially is advanced at a rapid rate and with relatively low force by a first fluid-operated actuator. When the leading end of the bar reaches the feed finger of the screw machine, a second fluid-operated actuator advances the bar at a slower speed and with relatively high force. A measuring device measures the distance through which the bar is advanced by the second actuator and automatically stops the advance when the leading end of the bar is located in a predetermined position.
