  • Die head assembly, apparatus, and process for meltblowing a fiberforming thermoplastic polymer
    Patent number: 6200120
    Abstract: A die head assembly for meltblowing thermoplastic material comprising a first chamber for receiving a pressurized fluid, a second chamber for receiving a pressurized molten thermoplastic material, the second chamber defining an outlet through which the molten thermoplastic material exits the die head, and a fluid tube removably securable to the first chamber and defining a passageway having an inlet in communication with the first chamber and an outlet extending at least into the outlet of the second chamber. The die head assembly of claim 1, wherein the outlet of the second chamber defines a longitudinal axis, and the outlet of the second chamber and the outlet of the fluid tube define at least one elongated opening therebetween elongated in a direction extending substantially perpendicular to the longitudinal axis, the molten thermoplastic material passing through the elongated opening as it exits the die head.
