Method for fixing the position of a print roller has axially sliding thrust elements with sloping thrust faces to move a support element radially

摘要

A method for fixing the position of a print roller, e.g. during roller changing, gas a fixing system with thrust elements (20) moving inside bores and backed by pneumatic or hydraulic pressure (38). The outer ends of the thrust elements have sloping thrust faces (22) which interact with sloping faces (24) of the fixing stub (14). With three thrust elements spaced about the tub a direct and precise radial position control is achieved.
