Abstract: The apparatus forms upon a pallet an orderly arrangement of stacks of sheet metal sections or cuttings at predetermined places with the aid of supporting rake means and abutment means following sheet metal shears. Scrap metal cuttings obtained by trimming or at the end of a sheet metal plate are received by a separate waste scrap metal collecting means positioned beneath a sheet metal feeding or infeed table and movable below the sheet metal shears. The sheet metal sections or cuttings are caught and entrained by automatically controlled catching means, such as an entrainment bracket, disposed at the supporting rake means, so as to be able to be moved horizontally in order that large accelerations and velocities can be achieved during the stacking of the sheet metal sections or cuttings.

Abstract: An easily releasable hydraulically pressurized clamping block assembly for attaching the bending tool to the ram of a folding press. A first clamping block having a recess to receive the tool abuts a bearing block at the rear thereof and is fitted with pins engaging in bores in the clamping block and in the bearing block while within the bearing block a longitudinal groove is provided which receives a hose which can be pressurized from a fluid pressure source through a control valve. Along the longitudinal groove between the above bores are holes which are fitted with springs which compress the hose when in a non-pressurized state. A modification provides pins with widened heads. Another modification uses straight pins and an intermediate block within the groove to press against the hose. Still another modification provides a groove in the ram itself rather than in a separate block.

Abstract: A machine for processing metal in sheet or plate form, especially for bending metal sheets. The machine comprises a frame with a table base on the frame and a ram which is vertically displaceable in relation to the table base. The ram has an upper tool, while a lower tool is disposed on the table base, these two tools cooperating to process the metal therebetween. The lower tool is elastically supported on the table base by means of a plurality of individual resilient supports which are arranged in a row on the table base. A plurality of intermediate parts are inserted between the table base and the supports and said parts are displaceable groupwise out of the effective region of selected supports into a neutral position, so that only the supports lying directly under the metal sheet workpiece to be processed are effective.

Abstract: A stop mechanism for a bending press, plate shear or the like machine, provided with a work-table and with a work-piece stop which is horizontally adjustable along the work table thereby defining the position of the work-piece relative to the machinery, the work-piece stop being coupled with a position control-unit which is provided with an indicator of the momentary position of the work-piece stop and can be programmed with the desired position, the stop being displaceable by means of a hydraulic piston-cylinder unit and a pump drive means controlled by the position control-unit.
