Gripper head for gripping arrangements for manipulating long workpieces, device for feeding long workpieces into and removing same from a processing machine and method for bend-straightening long workpieces

A gripping head of a grasping device configured to releasably grasp a long workpiece at an end region of the workpiece and to manipulate the workpiece by turning a long workpiece in a horizontal arrangement,

• the gripping head has first and second clamping jaws which are adjustable independently of one another and can be rotated about a central axis of rotation of the gripping head, clamping geometries of the first and second clamping jaws differ from one another, the first and second clamping jaws configured to be both movable relative to one another to enable the workpiece to be clamped and unclamped by and between the first and second clamping jaws, the gripping head has first and second guide rails running laterally on the gripping head, the first and second guide rails spaced from one another and running parallel to one another, the first clamping jaw movably connected to the first guide rail, the second clamping jaw movably connected to the second guide rail, the first and second guide rails are positioned about the central axis of rotation of the gripping head, the first clamping jaw configured to slidably move on the first guide rail, the second clamping jaw configured to slidably move on the second guide rail, said gripping head includes a first and second motor, said first motor configured to cause said first clamping jaw to move on said first guide rail, said second motor configured to cause said second clamping jaw to move on said second guide rail.
