  • Patent number: 4781092
    Abstract: An apparatus for feeding bar-like workpiece material in a severing machine is disclosed, which has an openable and closable pair of chuck jaws disposed nondisplaceably in the feed direction of the material before the cutting plane and an openable and closable pair of feed jaws disposed behind the cutting plane and displaceable in the material feed direction. In crossing the cutting plane, this pair of feed jaws can grasp the unworked material anew and, with the chuck jaws open, advance it. A pair of removal jaws is provided, disposed behind the cutting plane and displaceable in the material feed direction, with which the material to be severed can be grasped before the end of the severing cut and removed in the material feed direction after the end of the severing cut. It is also provided that the feed jaws are movable out of the displacement path of the removal jaws that extends in the material feed direction.

  • Patent number: 4342240
    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.
