    摘要： In a forming press, a blank is pressed formed into a press-formed workpiece by means of an upper die and a lower die, while a peripheral edge portion of the blank is clamped by means of a die and a blank holder insert of the forming press. Subsequently, a central portion of the press-formed workpiece is partially held by means of the upper die and the lower die so as to draw a peripheral portion of the press-formed workpiece away from the central portion thereof, thereby removing strain from the press-formed workpiece.

    摘要： Hydraulic stretch levelling machines have a stretch gripper head which is powered by a hydraulic piston and cylinder drive unit in order to stretch level a workpiece; the other end of the workpiece is secured by a counter gripper head which includes an anchoring mechanism for anchoring it in position and which is adjustable at discrete intervals for allowing for different sizes of workpiece. I propose separating the anchoring mechanism from the counter gripper head and connecting the counter gripper head to the anchoring mechanism by steplessly variable connecting means so that the position of the counter gripper head can be steplessly variable in order to allow for different lengths of workpiece and in order to bring the workpiece properly between the jaws of the gripper head, without using the hydraulic piston and cylinder drive unit for this purpose.

    摘要： A hydraulic section-stretching machine, having a cylinder and piston co-operating with a stretching grip, a longitudinally movable but arrestable counter-grip having clamping jaws operative perpendicularly to the section-stretching axis, the counter-grip being provided with two C-shaped apertures in the same plane, perpendicular to one another, one facing the stretching grip to accommodate the section to be stretched, and the other facing the stretched material to be transported, and a severing means close to the clamping jaws, acting in a vertical plane perpendicular to the stretching axis.

    摘要： A TENTER CLIP HAVING A BASE PLATE ON WHICH THE BORDER OF A STRIP TO BE CLIPPED IS PLACED AND A CLIP LEVER ROTATABLY PIVOTED TO THE CLIP BODY. THE CLIP LEVER CAN BE ROTATED IN SUCH A MANNER THAT THE LOWER END THEREOF IS BROUGHT INTO ABUTTING RELATIONSHIP TO THE BASE PLATE. THE LOWER END OF THE CLIP LEVER IS FORMED WITH A PLURALITY OF EDGES AT AN ANGULAR INTERVAL IN THE ROTATING DIRECTION OF THE LEVER AND AT DIFFERENT DISTANCES FROM THE FULCRUM POINT OF THE CLIP LEVER.
