Abstract: A method and apparatus for periodically feeding a rod-like workpiece into a severing machine for severing predetermined lengths in a cutting plane during cutting steps alternating with feeding steps. There are provided openable and closable clamping jaws for grasping the workpiece adjacent the cutting plane during each cutting step and openable and closable feed jaws for grasping the workpiece at a predetermined distance upstream of the cutting plane as viewed in the direction of feed and advancing the workpiece through the cutting plane by a distance corresponding to the desired length to be cut. The feed jaws are, subsequent to the feeding step and the closing of the clamping jaws, but prior to the completion of the cutting step, opened and moved away from the cutting plane by an extent that corresponds to the subsequent feed stroke and are thereafter closed again to grasp the workpiece anew.

The gantry supports, for vertical reciprocation, a horizontal cross beam carrying a plurality of article-handling tines for removing articles from, or depositing them in selected compartments of desired storage frames. Each tine is formed of two tine arms joined at right angles and is swingable into two mutually perpendicular positions for changing the orientation of the tine. For any one article-handling operation only one tine arm is active while the other is idle. Each storage frame carries a horizontal deflection bar to cause a tine to change its angular position when its horizontally extending tine arm abuts a deflection bar as the cross beam is lowered in between two storage frames.
