Claim Text:
1. A variable volume hot melt adhesive dispensing nozzle or die assembly, comprising: a first fluid flow of a first hot melt adhesive; a second fluid flow of a second hot melt adhesive; a plurality of hot melt adhesive dispensing nozzles, each one of said hot melt adhesive dispensing nozzle having a predetermined cross-sectional area; first and second choke slots, defined within a first fluid control plate, for causing said first and second fluid flows of hot melt adhesive to flow toward each other such that said first and second fluid flows can be combined into a single fluid flow at a fluid flow location located downstream from said first and second choke slots, and for effectively delaying the reaction of pressure spikes upon said combined fluid flow when one of said first or second fluid flows of said first and second hot melt adhesives is intermittently discontinued; and a second fluid control plate located downstream from said first fluid control plate and said first and second choke slots for combining said first and second fluid flows of said first and second hot melt adhesives into a combined flow of hot melt adhesive and for conducting said combined flow of hot melt adhesive toward said plurality of hot melt adhesive dispensing nozzles.
