Abstract: A clamping unit for containers at container treatment machines where, apart from a vertically movable lifting arm with a centering support for clamping a container from above, a motor for driving the lifting arm and a pneumatic spring against the resistance of which the centering support is mounted at the lifting arm so as to be movable to the top are provided. The lifting arms may be set to a desired vertical position independently of the movement or the rotational position of an associated rotary machine, and a clamping force of the centering supports may be easily and flexibly adjusted by applying a suited pressure to the pneumatic spring.

Abstract: A printing machine for printing onto containers, such as bottles, having at least a conveyor and a printing unit with a print head module, with at least one print head, a movement system for adjusting the position of the print head module, a measuring system for determining the position of the print head module and a control unit for controlling the movement system, where the movement system comprises a radial module for adjusting the position of the print head module in the radial direction and a height module for adjusting the height of the print head module in the vertical direction.

Abstract: A printing device for printing on containers in a rotationally-driven container conveying unit by means of which containers are conveyed between at least one container feed location and at least one container removal location, the printing device, and including at least one print head and at least one housing for housing a container. Each housing includes a hollow body, which is partially open at least in a printing area and which is used for accommodating the container, the opening for the printing area defining a front side and a side located opposite the front side defining a rear side.

Abstract: A device for transferring labels in a labeling machine with at least two retaining elements for holding labels, with the retaining elements being mounted offset in the circumferential direction around a gripper cylinder axle, and a mechanical control means configured to change the relative speed between the retaining elements in the circumferential direction of the gripper cylinder.
