[0003] It is known that for machining (handling) especially for printing or decorating on the outer surface of such hollow bodies, a precisely controlled, almost stepwise movement in the form of a rotation of the hollow body is essential for the operation of "machining" the outer surface is extremely important in terms of accuracy and reliability, see corresponding US patent publication US-A 6767357 (Joe Finan), which deals with printing operations, but does not present more detailed information about the clamping device

Embodiment Construction

[0024] The actual clamping surface 16 of the clamping device in the form of a clamping mandrel 1 passes through a plurality of preferably identical clamping segments 2a, 2b, 2c etc. (also referred to for short by reference number 2), each of which has a clamping surface The corresponding part-cylindrical outer surfaces of the parts are thus connected together to form the cylindrical clamping surface 16 . The clamping sections extend practically over the entire length of the clamping device 1 and are radially displaceably guided on the main body of the clamping device.

[0025] One embodiment is a clamping surface portion 2a' associated with the clamping section 2a. Corresponding structures also apply to the clamping section 2c and the clamping surface portion 2c'.

[0026] The body comprises a central shaft 3 extending over the entire length of the holding device and beyond one end of the holding device and on which two end wall elements 6 and 7 are fixed at suitable axial sp...

Abstract

Disclosed is a method for setting a beverage can as a rotationally symmetric hollow member embodied wherein the beverage can that is monolithically composed of a body and a bottom. The aim of the invention is to transmit accurate coupling and precise controlling of the movement of the mandrel to the hollow member. Said aim is achieved by providing several clamping segments (2; 2a, 2b, 2c) that form an outward-facing cylindrical clamping area (16) so as to grip an internal surface of the hollow member. The clamping segments are guided in a radially movable manner. A force transmitting mechanism (10, 13) that is arranged inside the mandrel (1) is used for synchronously controlling the radial movement of the clamping segments (2) such that a hollow member which is clamped by the clamping device can be accurately moved in a controlled fashion.

Description

technical field [0001] A method and a clamping mandrel for receiving and precisely fixing a hollow body for controlled precise movement are proposed. That is to say, it is proposed that the position of the hollow body can be precisely positioned such that digital printing on the outer side surface of the hollow body can be achieved with a high degree of precision. Digital printing replaces the coloring and decorating of the outside of the hollow body, which has hitherto been applied by the printing blanket method. [0002] The present invention relates to a cylindrical holding device for rotationally symmetrical hollow bodies, in particular for cans or barrels (cans) comprising a body and a bottom integrally formed thereon, substantially having a dome-shaped inwardly curved bottom. Background technique [0003] It is known that for machining (handling) especially for printing or decorating on the outer surface of such hollow bodies, a precisely controlled, almost step-by-s...
