摘要： A coating apparatus for applying a stripe of fluid coating material over the longitudinal seams of a series of can bodies moving along a can forming line with the coating apparatus within the interior of the can bodies including a fluid manifold module removably secured to an end cap member and communicating with sources of air and fluid coating material under pressure through the end cap member, a coating module removable secured to said end cap member and having a pneumatically operated valve therein for selectively opening and closing a fluid flow passageway to control the discharge of coating material onto the seams of can bodies, and preferably a solenoid valve mounted in the air flow passageway in the fluid manifold module adjacent the coating module for controlling the flow of air to operate the coating material valve. The coating apparatus having the solenoid mounted directly adjacent the coating module is characterized by its relatevely high cycle rates and relatevely small diameter with the overall coating apparatus being very easy to disassemble for maintenance, repair or replacement of components.

摘要： A spray gun for airless atomization and electrostatic deposition of a coating material upon a substrate, including a gun nozzle tip element serving to prevent arcing from the gun nozzle tip to an adjacent electrical ground. As disclosed, the airless spray gun includes a metallic nozzle tip from which atomized liquid coating material is emitted, and the thus-emitted coating material is charged by an electrode mounted on the nozzle which is electrically isolated from the metallic tip. During use of the spray gun, the metallic tip becomes charged via electrical charge conduction through the emitted atomized coating material. To prevent arcing from the charged tip to an electrical ground, a pair of resistive threads are secured in bores in the spray gun nozzle, each having a first end electrically connected to the conductive tip and a second end extending slightly beyond the nozzle. If an electrical ground approaches the charged conductive tip, the resistive threads are positioned such that electrical energy on the tip is coupled to the electrical ground through one or both of the resistive threads in the form of a low energy corona discharge.

摘要： Apparatus and methods for spray coating selected areas of a circuit board with an insulative coating material without coating regions of the circuit board to be left uncoated. A liquid spray device emits the coating material and an air assist attachment connected to the liquid spray device directs jets of air into impinging relation with the coating material emitted therefrom to transform the coating material into an atomized, shaped spray pattern for coating the selected areas. The air assist attachment can be disabled so that the spray device transforms the coating material into a non-atomized, shaped spray pattern for coating selected areas without coating regions of the circuit board to be left uncoated.

摘要： A film coater for applying a coating material to selected areas on a target substrate, such as a printed circuit board, having a vented dispenser body with a plunger moveable therein between an open and closed position. A flow of pressurized air which moves the plunger to the open position is controlled by a valve carried by the dispenser body, and a plurality of springs return the plunger to the closed position. The number of return springs is selected to provide a variable biasing force so that movement of the plunger is controlled to eliminate or at least significantly reduce hammering, tapering and drooling, particularly when the dispenser is operated intermittently.
