Title:
MANDREL USED FOR DIGITAL PRINTING ON CAN MEMBERS
Document Type and Number:
WIPO Patent Application WO2007051848
Kind Code:
A9
Abstract:
Disclosed is a mandrel for a rotationally symmetric hollow member embodied as a 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.
