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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
