Abstract

The method involves feeding coating and/or flushing material into a cylinder (12A,B) of a dosing unit (10A,B) and feeding it into the coating arrangement (1), especially via a line (27A,B) with a scraper. A piston is moved in the cylinder by a drive controlled to fill or empty the cylinder with a defined quantity of coating and/or flushing material. The pressure of the material in, fed to or removed from the cylinder is measured by a sensor (DSA,DSB) and coating system parameters are monitored using the resulting measurement signal. Independent claims are also included for the following: (a) a supply system for dosed material supply for a coating arrangement (b) and a dosing unit for an inventive system.
