ABSTRACT OF THE DISCLOSURE A mechanism for cleaning the discharge opening lips of a coating control nozzle by controlled movement of a plurality of brushes transversely along the noz- zle lips. A carriage is mounted on a support frame and is moved along the frame by a rodless cylinder. A plurality of brushes rotated by air motors are mounted on one end of a bellcrank which is attached to the carriage and are pivotally moved into and out of engage- ment with the nozzle lips by a fluid actuated cylinder mounted on the carriage. One of the brushes engages and cleans the inside surface of both nozzle lips simultaneously with two pairs of brushes which clean the outside surfaces of both lips as the carriage moves the brushes transversely along the nozzle opening. A stop is engaged by the bellcrank to limit the pivotal movement of the bellcrank to position the brushes with respect to the nozzle lips. The brushes may be re- placed with scraper blades mounted on the end of the bellcrank.
