20220143845 · 2022-05-12 · ·

A gripper, which removes blanks from a web of material lying flat, includes gripping elements which can each be actuated separately. The gripping elements are mounted independently of one another in a frame so as to be displaceable perpendicularly to a reference plane parallel to the web of material. The gripping elements are set against the web of material and actuated in a takeover position of the gripper aligned with respect to the blank by means of a control device. In addition to the gripping elements located inside the contour line, there are also other gripping elements adjacent to the blank and located outside the contour line that are set against the material web as downholders. Gripping elements within the contour line of the blank are actuated and retracted from the material web, taking along the blank, before the gripper is lifted off the material web from the takeover position.
