    摘要： A lamellar die apparatus for extruding a heated liquid into filaments and directing air at the filaments. The apparatus includes a plurality of plates each having opposite side faces. At least two of the side faces confront each other and have a liquid passage positioned therebetween for transferring the heated liquid. At least two of the side faces confront each other and have an air passage positioned therebetween for transferring the air. At least two of the side faces confront each other and have a heating element passage therebetween. A heating element is positioned within the heating element passage for heating at least two of the plates. An extrusion die is coupled with the plurality of plates and communicates with the liquid passage and the air passage for discharging the heated liquid as multiple filaments and for discharging the air at the filaments.

    摘要： An apparatus for extruding multiple types of liquid materials into multi-component filaments. A pair of outer manifold elements sandwich an intermediate manifold element. Respective channels are formed between opposing sides of the outer manifold elements and the respective opposite sides of the intermediate manifold element. These recesses form channels which diverge or widen away from associated inlets at the top of the manifold assembly. A die tip is coupled to the manifold assembly at a lower side and communicates with the outlets of the channels. The die tip includes a combining member for producing a desired multi-component filament configuration.

    摘要： Apparatus and methods for folding a nonwoven web without mechanical contact against a folding surface. A first portion of the nonwoven web is secured to a collector by vacuum and a positive pressure differential is applied to a second portion of the moving nonwoven web. An unbalanced lifting force applied by the positive pressure differential causes the first portion to fold along a longitudinal fold line extending in a machine direction and to assume an overlapping relationship with the second portion. The vacuum assists in the folding process and maintains the overlapping relationship until the nonbonded nonwoven web is consolidated. One or more elastic strands or bands may be captured in the space defined between the overlapped first and second portions.

    摘要： A yarn of meltblown thermoplastic fibers is manufactured by meltblowing fibers onto a collector to form a thin web thereon, and continuously withdrawing and twisting the web into a generally circular yarn. In a preferred embodiment the yarn has a reinforcing cord disposed therein to lend strength thereto. The yarn is suited for many applications, including knitted and woven fabrics, and cartridge filters.

    摘要： A polymer metl delivery system includes a preheated hopper, a high clearance auger, a gear pump, and provisions for delivering heat to the polymer. The resin is melted and fed to the auger and pumped to the gear pump and further pump to an extrusion die. Heat is added to the polymers from the hopper and throughout its course to the outlet connection for the extrusion die. The preheated in the hopper includes heat conductive fins. The system is particularly suited for use in combination with a meltblowing die.

    摘要： A segmented die assembly comprises a plurality of side-by-side and separate units. Each die unit, includes a manifold segment and a die module mounted thereon. The manifold segments are interconnected and function to deliver process air and polymer melt to the modules. Each module including a nozzle through which the polymer melt is extruded forming a row of filament(s). The filaments from the array of modules are deposited on a substrate or collector. The die assembly is preferably used to apply a hot melt adhesive to a substrate, but also may be used to produce meltblown webs.
