Printing machine cylinder coating device - has electric setting drive selectively adjusting dosing elements extending across cylinder surface

摘要

The device comprises a container for the surface coating ink (2) within which the printing machine cylinder (1) rotates, with dosing elements (4), controlling the thickness of the surface coating. The dosing elements are selectively coupled to a precision setting drive (14) for determining the spacing from the surface of the cylinder, under control of a positioning device (19, 20). The coupling elements (10, 11) between the setting drive and the dosing element lie in a plane parallel to the rotation axis of the cylinder, the drive displaced linearly to engage the coupling when the dosing element is to be re-adjusted. ADVANTAGE - Accurate adjustment of final dosing elements using simple setting drive.
