摘要： Objects are coated with a coating material which is normally solid at room temperatures. The material is liquified at elevated temperatures and sprayed onto the cooler objects in a heated cabinet (18), whereupon the material at least partially solidifies on the object (P). Thereafter, heat is applied to the coating material to cause it to flow out over the coat surface. Overspray is maintained in liquified form within the cabinet (18) where it is reclaimed and flows to a heated sump (28) for direct recirculation to the spray apparatus. There are no deleterious solvent emissions. Apparatus and methods are provided.

摘要： A system for spray coating a substrate such as a flexible web of plastic film with a gas barrier coating containing a polymer dispersion. The system includes a spray coating booth or chamber including spray nozzles dispensing a spray of coating material onto the surface of a web of material continuously moving into and out of the coating chamber. A series of feed rollers move the web into the coating booth into proximity to the spray nozzles such that on actuation of the nozzles a stream of coating material coats both sides of the surface of the web with a wet coating layer. The coating booth includes a system for containing and removing the airborne liquid overspray carried from the booth with the web without disturbing the wet coating on the web and without substantially drawing of overspray from the coating chamber.

摘要： A system for spray coating a substrate with a liquid coating material incorporating a coater provided with a chamber in which spray nozzles (26a,26b) are provided to spray the liquid coating material on to a substrate (l0) which is moved through the chamber by appropriate means. Overspray control means are provided to convey airborne overspray from the coating chamber wherein particles of film-forming material in the overspray are collected. Air flow control means are provided to draw ambient air through the chamber at such a rate that airborne overspray is transported to the particle collector without drawing substantial spray material from the chamber.

摘要： An automatic safety system is built into a pneumatic motor (13) actuated dispensing gun to prevent the gun from dispensing liquid material whenever the nozzle of the gun is loosened or removed from the gun body. The safety system comprises an airflow passage (100,101,102) contained internally ofthe gun body for connecting the pneumatic motor (13) to a normally sealed surface located between the nozzle and the gun body. Removal or loosening of the nozzle relative to the body, breaks this sealed surface and results in leakage of sufficient air pressure to atmosphere as to prevent actuation of the pneumatic motor and thus opening of the normally closed flow control valve of the gun.
