Gripper movement means acts on a thrust pivot (22) that protrudes from the body of the gripper. This pivot (22) is received axially slidable in a seat (25) in the body of the pivot and between ends of the pivot inside the seat and the bottom of the seat a buffer (26) is arranged that is made of an elastically yieldable material.
Buffer compression adjusting means can be provided. |
