Abstract
Automatic finish coating equipment employs a selectively variable low-pressure or 'soft' air or solvent signal to control pushing of coating material through a feed tube from a coating material source to a coating material atomizing and dispensing device. This 'soft fluid push' method maximizes the finish quality which can be achieved with coating materials having different characteristics, such as viscosities, in any operation in which frequent changes in coating material characteristics are experienced, such as, when frequent changes of coating material color are employed. The disclosure also describes that the 'soft push' through the delivery lines should be reduced as the length of the slug of coating material in the delivery lines decreases.
