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.
