Mandrel for digital printing

摘要

Mandrel has several clamping segments (2a) forming cylindrical clamping surface (16) for engaging inner surface of hollow body and the clamping segments are guided to move radially in a synchronous manner. A power transmission device (10,13) is arranged inside the mandrel for controlling radial movement of the clamping segments by which the clamped hollow body is moved in a precisely controlled manner. An independent claim is also included for procedure for accurate positioning and controlling the hollow body.
