Coating device for cold bottles or like containers

摘要

Cold bottles or other containers are transported by a conveyer, and, while being translated, the containers are rotated by a drive belt provided on one side of a line containers. Air is sprayed and coating fluid is applied on other side of the line of containers. Coating fluid is applied onto the containers by fluid application rolls at two levels having axes parallel to the direction of translation of containers. Coating fluid is supplied from spray nozzles to the fluid application rolls through sponge rolls contacting the fluid application rolls.
