摘要： Apparatus and methods for producing intermittent, discrete patterns of coating material onto discrete irregular substrate areas, such as electronic circuit boards, where the patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the coating material flow. Also, the air flow is continued beyond that point in time, when the coating material flow ceases. The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds. Alternatively, the lead and lag air start and stop times on each side of the film of coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the circuit board. The air flow carries the film coating material to the circuit board for deposition in discrete areas thereon. The sharp cut-on and cut-off accommodate multiple discrete area coating or multiple automated circuit board coating.

摘要： Coating dispenser apparatus and methods which utilize a snuff back device for removing a small amount of coating material from the discharge passage of the dispenser upon shut-off thereof at the end of a coating run. A control is provided which discharges the material removed from the discharge passage back into the discharge passage upon a predetermined delay after the start of the next coating run. The disclosed methods contemplate the discharge of coating material back into the discharge passage in the middle of the next coating pattern, or depending on the application, during any segment of the next coating pattern after a defined leading edge of the pattern is created, during which segment the coating material discharged back into the discharge pattern smoothly blends into the coating pattern as it is applied to a substrate. The apparatus and methods are especially useful for applying conformal coating patterns onto circuit boards.

摘要： Apparatus for producing intermittent, discrete patterns of coating material, such as hot melt adhesive, onto discrete substrates or substrate areas, such as book spines, sift-proof carton flaps and pinch-bottom bags. The adhesive patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow. Also, the air flow is continued beyond that point in time, when the hot melt flow ceases. The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds. Coating weights down to 1 gram per square meter at about 350 meters per minute substrate speed are provided. Alternatively, the lead and lag air start and stop times on each side of the film of coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the substrate. Methods are disclosed.

摘要： Apparatus for producing intermittent, discrete patterns of foam coating material, onto discrete substrates or substrate areas, where the patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. Air flow is initiated from both air slots prior to the initiation of the foam flow. Also, the air flow is continued beyond that point in time when the foam flow ceases. The delays between the operations of the air flow and the foam coating flow are on the order of micro seconds. Alternatively, the lead and lag air start and stop times on each side of the foam coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the substrate.

摘要： A slot die for producing a fibrous web of adhesive material includes a segmented shim having a plurality of fingers in said slat dividing adhesive material into a plurality of adhesive streams. The fingers have tapered ends which are flush with or extend slightly beyond the slot nozzle outlet. Separate material streams emanate from the slot nozzle outlet where they merge and are engaged by air flow producing a fibrous web of adhesive material. The adhesive and air flow are started and stopped at intervals to produce discrete fibrous webs having square, sharp leading and trailing edges.

摘要： Apparatus and methods for producing coatings, such as wax or hot melt adhesive, onto the tops and necks of wine bottles or similar objects. A slot nozzle die has elongated air slots along a vertically oriented slot extrusion opening. A hot melt or wax gun is disposed above the bottle neck to apply a bead of adhesive to the bottle top. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow and is continued beyond that point in time, when the hot melt flow ceases. The air carries a film of coating material horizontally to the bottle neck. Means are provided for spinning the bottle about its vertical axis. The delays between the operations of the air flow and the coating flow are on the order of micro seconds. The merged coatings are heated to smooth the coating finish to produce a traditional neck seal.
