Latest Patents

One of Miller's latest patents is titled "Process and apparatus for increasing the isotropy in nonwoven fabrics." This innovative method involves changing the position of fibers in a nonwoven web to enhance its isotropy. By utilizing an angled stream of fluid, the streams form a substantially coplanar curtain that impinges on the fibers at their leading ends, trailing ends, or sides. Another significant patent is "Apparatus for cutting filamentary material." This invention modifies a reel-type staple cutter by incorporating a housing that surrounds the cutter reel. The housing features a cam slot designed to allow the passage of a single tow while preventing the passage of a knot tying together two ends of the tow. As the cutter turns, the knot slides along the outside of the slot, reaching the top of the housing, where it remains until the ends of the knot are cut. Means are provided to remove the knot effectively.
