Gravierkopf fuer ein Geraet zum Gravieren von Tiefdruckzylindern und aehnlichen Druckformen

摘要

In an engraving head for apparatus for engraving printing cylinders, a drivable engraving tool and a sensing organ contacting any printing cylinder being engraved by the drivable engraving tool are mounted on a common fixture. A damping element is located between the sensing organ and the engraving tool for at least substantially barring transmission of oscillations from the sensing organ to the engraving stylus, while preserving a firm and accurate guidance of the drivable engraving tool by the sensing organ contacting the printing cylinder. Damped sleeve structures and collets for mounting a sensing stylus include such damping elements.
