发明名称 Metering system for hot melt adhesives with variable adhesive volumes
摘要 A method of making an article having a substrate and a material applied thereto includes providing a metered fluid dispensing system having a supply of fluid to be dispensed, an output device having at least one dispensing nozzle, at least two pumps for pumping fluid from the supply to the at least one dispensing nozzle. The pumps are in close proximity to the dispensing nozzle. Output supply passageways interconnect the pumps and the dispensing nozzle, and flow control elements selectively control the passage of the fluid from the pumps to the nozzle. The substrate is conveyed past the fluid dispensing system in a machine direction and fluid is applied to the substrate in a plurality of segments. Each segment has a volume per unit length and is applied in a length in the machine direction to define a pattern. The pattern includes at least some areas in which the fluid is present at a first volume as applied from one of the pumps and at least some areas in which fluid is present at a second volume that is greater than the first volume, as applied from both of the pumps.
