Claim 17:
18. A method comprising receiving a container in a gripper, said gripper comprising first and second arms having corresponding first and second faces formed therein and a controller disposed between said arms for pivoting said arms towards each other, said arms being pre-loaded by a spring, wherein first and second rollers are arranged at said controller and rotate about a central control axis thereof, wherein pivoting each of said gripper arms comprises causing said controller to guide movement of said rollers along said faces, said faces being shaped such that, in response to movement of said first and second rollers, said first and second arms carry out an equiangular and symmetric pivoting between an opened and closed position of said gripper, wherein said first and second arms are gripper arms, wherein said first and second rollers are control rollers, wherein said controller is a rotatable control unit, wherein said first and second faces are inner control faces, and wherein movement along said first face is selected from the group consisting of sliding and rolling, said method comprising opening said first and second arms, receiving container between said first and second arms, and closing said first and second arms, wherein opening said first and second arms comprises causing a first rotation to move said first and second rollers along said first and second faces, thus overcoming a closing force from said spring to open said gripper, wherein closing said first and second arms comprises causing a second rotation, thereby permitting said controller to guide movement of said rollers along said first and second faces under said influence of said spring, which urges said arms into a closed position to close said gripper, and wherein said first and second rotations are rotations of ninety degrees.
