Abstract
An improvement is provided in a coating system including a dispenser, a coating outlet for delivering a coating material to a surface of a moving workpiece to which coating is to be applied in a desired pattern, and a dispensing control for producing control signals in a predetermined fashion for initiating and terminating the release of coating material to the outlet. The improvement includes a wiping member selectively advanceable and retractable relative to the coating outlet for wiping excess coating material therefrom and a cleaning control responsive to predetermined control signals from the dispensing control for advancing and retracting the wiping member in a predetermined fashion.
