Abstract: An improved method of operating an apparatus to cut sheet material workpieces eliminates the inadvertent dropping of a relatively small scrap or remainder portion of a workpiece into a clearance space between a pair of cutter blades and a discharge conveyor. Thus, a relatively large sheet metal workpiece is gripped by a holder which moves the workpiece relative to a pair of blades. The blades are moved relative to each other to cut the workpiece to form a product having a desired configuration. The product is dropped onto a discharge conveyor. In order to prevent a relatively small scrap piece remaining in the holder from being dropped into a space between the discharge conveyor and the blades, the holder is extended through the space between the blades to a location over the discharge conveyor and is opened to drop the scrap or remainder portion of the workpiece onto the discharge conveyor.

The apparatus includes a base and superposed frame, a press head with punch, which is reciprocally mounted in the upper part of the frame and a rotatably driven eccentric shaft which engages, so as to reciprocate the press head. As the press head reciprocates, the punch engages the receiving end of a gas burner tubing which is supported in a tube collar positioned within the lower part of the frame. The trailing end of the tubing is supported upon a tube arbor which is advanced incrementally towards the tube collar, as the punch is reciprocated. The apparatus is characterized by its capability of rapid punching of a longitudinally aligned series of ports in a gas burner tubing, with precise adjustment of port size and distance between ports.

Abstract: A large rectangular plate is subdivided into small rectangular sections in a system wherein the plate is fed stepwise in a main direction through an upstream shear while the downstream end portion of the plate is seized immediately downstream of the shear with each advanced step. Between the advanced steps the end portions are sheared off and then displaced in the main direction to the upstream end of a conveyor where they are deposited one after the other. The conveyor displaces the sheared-off end portions until each one is positioned above a respective aligner spaced apart in the main direction. The conveyor lowers these sections onto the aligners and the aligners then align them perfectly perpendicular to the main direction. The aligned and sheared-off end portions are then pushed jointly in a transverse direction perpendicular to the main direction stepwise to a downstream shear while they are supported and pneumatically seized at their downstream ends immediately downstream of the downstream shear.

Abstract: The invention relates to a method and device for cutting a bundle of tubes containing a nuclear fuel into pieces having a preset length so that the fuel can be dissolved in a suitable solution.The bundle of tubes is introduced into a guide tube in a shearing machine and is clamped by two side clamps within the tube so as to limit the width of the bundle to the diameter of one tube of the bundle. The side clamps subject the bundle to a sideways thrust so that the tubes in the bundle are maintained contiguous without any excessive curvature. The bundle of tubes is then submitted to a cutting operation at right angles to its major dimension and after the blade has been returned to its inoperative position a safety plate is positioned near the cut section at a distance slightly greater than the forward movement of the bundle between two successive cutting operations. The side clamps are then withdrawn by a limited amount so that the resilience of the tubes causes them to remain in contact with the clamps.
