Abstract
A continuous coater of the type having a conveyor extending through a coating booth where paint or other material is sprayed onto the products as they are conveyed through the booth. The booth has an air flow control vestibule located adjacent the entrance and exit ports. Each vestibule is connected to an air flow exhaust system and is so configured that it is operative to draw air almost exclusively from outside the booth into the exhaust system so that there is a minimum of input air to the exhaust system from within the booth. The incoming air from outside the booth effectively forms a flow barrier to the egress of sprayed material and/or solvent to the atmosphere through the vestibule entrance and exit ports. Preferably, there is located in each vestibule means for creating an air curtain which functions to minimize the egress of paint or solvent from the coater cabinet and to provide a more nearly saturated atmosphere inside the cabinet.
