Beschreibung
Zusammenfassung:	A bar loading machine for the automatic feeding of bars to an automatic screw machine or other bar machine includes a bar-engaging device, a feed chain for driving the bar-engaging device, a start switch arrangement for sensing the arrival of the leading end of a bar, and a feed control arrangement. The feed control arrangement establishes the feed distance required for properly positioning the leading end of the bar in the bar machine, and includes first and second distance-measuring arrangements which successively and independently of each other control the movement of the feed chain. The first distance-measuring device includes a fixed stop arrangement for limiting the feeding of a bar.
