연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A method of making an article having a substrate and two materials applied thereto includes providing a metered fluid dispensing system having first and second supply sources for supplying first and second fluids, respectively, an output device having at least one dispensing nozzle, and at least two pumps for pumping the first and second fluids from their respective supply sources to the at least one dispensing nozzle, the pumps being in close proximity to the dispensing nozzle. The dispensing system is configured to selectively control the passage of the first and second fluids from each one of the at least two pumps to the at least one dispensing nozzle. The substrate is conveyed past the fluid dispensing system in a machine direction and the first, or second, or first and second fluids are applied to the substrate in a plurality of segments, each segment having a volume per unit length and applied in a length in the machine direction to define a pattern, and in which wherein the pattern includes at least some areas in which the first or second fluid is present without the other fluid.

1. A method of making an article having a substrate and two materials applied thereto, comprising: providing a metered fluid dispensing system having first and second supply sources for supplying first and second fluids, respectively, an adhesive manifold, an output device fluidically connected to the adhesive manifold and having at least one dispensing nozzle, first and second pumps for pumping the first and second fluids, respectively, from their respective supply sources to the at least one dispensing nozzle, output supply passageways interconnecting the first and second pumps to the at least one dispensing nozzle, the output supply passageways comprising a first passageway and a second passageway, the first and second passageways intersecting to form a third passageway extending from an intersection of the first and second passageways to the dispensing nozzle, the third passageway downstream from, and in fluid communication with the first and second passageways, and flow control elements to selectively control the passage of the first and second fluids in a direction from each one of the first and second pumps to the at least one dispensing nozzle, wherein at least one flow control element of the flow control elements is an actuatable valve positioned in the third passageway, and another flow control element of the flow control elements is a plug removably positionable entirely within one of the first passageway and the second passageway at a boundary of the adhesive manifold and the output device, the dispensing system configured for at least four dispensing states, a first state in which the first fluid is dispensed from the first pump to the at least one dispensing nozzle, the another flow control element is removably positioned in one of the first passageway and the second passageway to prevent dispensing of the second fluid, and the valve is OPEN, a second state in which the second fluid is dispensed from the second pump to the at least one dispensing nozzle, the another flow control element is positioned in the other of the first passageway and the second passageway to prevent dispensing of the first fluid, and the valve is OPEN, a third state in which first and second fluids are dispensed from the first and second pumps to the at least one dispensing nozzle and the valve is OPEN, and a fourth state in which the first and second fluids are not dispensed from the first and second pumps to the at least one dispensing nozzle and the valve is CLOSED;conveying the substrate past the fluid dispensing system in a machine direction; andapplying the first, or second, or first and second fluids to the substrate in a plurality of segments, each segment having a volume per unit length and applied in a length in the machine direction to define a pattern, and wherein the pattern includes at least some areas in which the first or second fluid is present without the other fluid in the machine direction. 2. The method in accordance with claim 1 wherein the first and/or second fluid is non-contiguous in the machine direction. 3. The method in accordance with claim 1 wherein the first and/or second fluid is non-contiguous in the transverse direction. 4. The method in accordance with claim 1 wherein the first and/or second fluid is non-contiguous in both the machine direction and the transverse direction. 5. The method in accordance with claim 1 wherein the first and/or second fluids are applied in a contact application. 6. The method in accordance with claim 5 wherein the contact application is a slot-coated application. 7. The method in accordance with claim 1 wherein the first and/or second fluids are applied in a non-contact application. 8. The method in accordance with claim 7 wherein the non-contact application is a spray coating application. 9. The method in accordance with claim 1 wherein the pattern includes at least one of a window frame, a ladder and a stepped pattern. 10. The method in accordance with claim 1 wherein the application of the first and second fluids is, at least in some areas, coincident with one another. 11. The method in accordance with claim 1 wherein the volume of one or both of the first and second fluid is increased per unit length for at least a predetermined length of a segment in the machine direction. 12. The method in accordance with claim 1 wherein the volume of one or both of the first and second fluid is increased per unit length for at least a predetermined length of a plurality of segments in a transverse direction. 13. The method in accordance with claim 1 wherein the metered fluid dispensing system includes at least two dispensing nozzles and at least two first and second pumps associated with each of the first and second fluids. 14. The method in accordance with claim 1 wherein the passageways are disposed within a manifold. 15. The method in accordance with claim 1 including the step of applying a member over the substrate and the first or second or first and second fluids. 16. The method in accordance with claim 1 wherein the first fluid is dispensed for a first predetermined period of time and the second fluid is dispensed for a second predetermined period of time. 17. The method in accordance with claim 16 wherein the first and second fluids are dispensed simultaneously. 18. The method in accordance with claim 1 wherein one of the fluids is a adhesive and the other of the fluids is a catalyst. 19. The method in accordance with claim 1 wherein the pattern is a window box pattern. 20. The method in accordance with claim 1 wherein the pattern is a ladder pattern. 21. The method in accordance with claim 1 wherein the pattern is a striped pattern. 22. The method in accordance with claim 1 wherein the pattern is a free-form pattern.
