ABSTRACT:
A vacuum gripper for holding objects having curved surfaces includes a plurality of hollow arms extending outwardly from a flex axis. The arms are individually flexible with respect to the flex axis and normally lie in the same plane. Each arm supports a vacuum cup at the free end thereof. The arms individually flex when the cups contact a curved surface so that all cups grasp the object firmly irrespective of the configuration of the curved surface.
