By means of a gripper (1) for retaining containers such as PET bottles, wherein the gripper arms (2, 3) between the rotational axis (4, 5) and the free claw end (2a, 3a) and the carrier element for the gripper arms have receptacles for permanent magnets for closing and/or centering, a solution should be created, by means of which the closing forces should be applied by means of magnets and the centering of the grippers at a star or a similar machine element or the protection against overloading should be reduced. This is achieved in that each gripper arm (2, 3) has a pair of permanent magnets (8, 9; 10, 11) and the carrying element (8a, 9a; 10a, 11a) has two associated pairs of permanent magnets oriented parallel to the rotational axis, wherein each permanent magnet (8-11) has a pole that is opposite that of the adjacent magnets in horizontal and/or vertical association. |
