METHOD OF AND APPARATUS FOR COATING ARTICLES

摘要

Title of the Invention METHOD OF AND APPARATUS FOR COATING ARTICLES A method of and apparatus for applying a synthetic resin coating of predetermined thickness to various articles of different sizes and shapes from a relatively rapidly deteriorating solution of the resin in which an intermittently driven conveyor housed in a controlled atmosphere and suspending different article groups of like articles at spaced locations along the conveyor successively moves the articles from a loading station first to a cleaning station at which the articles are subjected to the action of an ultrasonic cleaner,then to a destaticizing station, then to a coating station at which a dip tank is rapidly raised to immerse the articles in the solution and is lowered at a controlled rate to provide a coating of the required thickness in a single operation, and finally through a precuring zone in which the coating dries tack-free to the loading station at which the coated precured articles can be removed. The coating solution is continuously circulated through the dip tank in such a way that the tank is always brim full and through a filter and chiller which maintains the solution below a predetermined temperature.
