Claim:
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; and applying 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.
