the gripper element 13 which in the position illustrated in fig4 is in the immediate vicinity of the transport element 15 projects beyond a vertical central plane of the coiler can 8 the central plane is oriented parallel to the travel direction of the transport carriage 9 in such an orientation the end 10 39 serves as a braking counterelement making possible a more rapid can transport turning to fig5 the one piece gripper element 13 has the shape of a semicircular annular segment the inner circular surface 13 39 of the gripper element 13 which serves as the engaging jaw surface has a diameter which is greater than that of the can 8 so that an unobstructed entry and exit of the can 8 into and out of the concave curvature of the jaw opening is ensured the gripper element 13 is mounted on the gripper carrier 16 which in a sled like fashion is displaceable as indicated by the arrows m and n a toothed belt 17 is secured to the gripper element 13 at both ends and is designed to have a loop which is guided around a drive sprocket 18 which in turn is rotated by a motor 18 39 accommodated for example in the chassis 11 of the carriage 19 the drive sprocket 18 is supported on the.
