Abstract

The wetting system has a rotating delivery roller (4) driven by a separate independent drive motor (5) with a variable rate of rotation, which clips into a liq. bath (3) for receiving a thin liq. film. The thickness of the latter is regulated across the width of the roller (4) via a resilient scraper blade which is biased against the roller surface. The scraper blade is acted on by a number of separately regulated biassing elements along its length, controlled by an electronic evaluation stage (24) also used to regulate the speed of the drive motor (5) in response to the supplied printing machine operating parameters.
