Abstract
The present invention pertains to processes and gripping devices for picking up, transporting, and depositing flexible, limp, flat workpieces (1) made of textile material, plastic, or other materials that can be grasped with needles (3). To handle such workpieces (1) rapidly and reliably even under complicated spatial conditions, needle grippers (2) are brought by a manipulating device (5) into a position parallel to the workpiece (1) and, after grasping the workpiece (1), into another position in which the horizontal projection of the workpiece is reduced and in which the workpiece (1) assumes an approximately loop-like shape, in which position the workpiece (1) is transported and deposited.
