Abstract: A system and method for applying fluids, including fiberized hot melt adhesive, onto a substrate from one or more meltblowing die assemblies mounted on a manifold that supplies fluid thereto. At least one of the die assemblies is selected from a group of die assemblies having different configurations of fluid dispensing orifices, wherein various combinations of the different die assembly configurations are mountable onto the manifold to provide a wide range of partial fluid dispensing patterns onto the substrate. Each of the plurality of fluid dispensing orifices are flanked by an air dispensing orifice disposed on opposing sides thereof, wherein air dispensing orifices may extend across a portion of the remaining portion of the meltblowing die assembly void of fluid dispensing orifices. At least one of the die assemblies having air dispensing orifices arranged relative to the fluid dispensing orifices to increasingly decrease an oscillation amplitude of fluid dispensed from the fluid dispensing orifices approaching an endmost fluid dispensing orifice thereof.

Abstract: A new and improved strand coating system comprises a strand guide block which serves to properly position and orient a plurality of elongated, parallel strands, which are being respectively conveyed in front of a plurality of the material dispensing nozzles, in such a manner that the plurality of elongated, parallel strands can assuredly be respectively disposed within common planes which are effectively formed between the strand guide slots defined within the strand guide block and the plurality of material dispensing nozzles whereby the dispensed hot melt adhesive materials can be properly applied to and coated upon the elongated strands prior to the adherence of the elongated strands upon suitable substrates so as to, in turn, ensure the desirably secured adherence of the plurality of elongated strands upon the particular substrates when the elongated strands and the substrates are mated together. The plurality of strand guide slots may have substantially V-shaped cross-sectional configurations or substantially L-shaped cross-sectional configurations, and the strand guide block can be mounted either upon the module assembly or the dispensing nozzle assembly so as to be disposed at elevational positions which are either vertically above or below the hot melt adhesive dispensing nozzles in order to accommodate vertically upward or vertically downward strand conveyance systems.
