ABSTRACT:
An improved loader mechanism is used with a machine tool having a chuck which is operated between opened and closed conditions and a bar feed mechanism having a feed gripper which is also opened and closed. The loader mechanism is operable to transfer one piece of bar stock at a time from an intermediate station to a loading station while simultaneously transferring another piece of bar stock from a magazine to the intermediate station. After a piece of bar stock has been moved to the loading station, the piece of bar stock is registered relative to the feed gripper and chuck by activating a compensating cylinder to press the leading end of the piece of bar stock against a stop member. When the stop member has been moved out of the way of the registered piece of bar stock, a main cylinder is activated to push the registered piece of bar stock into the open feed gripper and chuck.
