  • Method for separating particulate materials from fibrous materials during start-up of texturizing process
    Patent number: 4502195
    Abstract: In accordance with the present invention, entrained, dense particulate materials are removed from an elongated body of less dense fibrous materials being transported by a moving fluid stream by reducing the velocity of said fluid stream by an amount and for a time sufficient to release a substantial portion of said dense particulate materials, but insufficient to stop the transport of the elongated body of less dense fibrous material by the moving fluid stream.

  • Thread control in textile machines
    Patent number: 4331008
    Abstract: A thread monitor for use in textile machines monitors thread tension (i.e. to detect thread breakage or relaxation) and the presence of knots in the thread. If either is detected the monitor issues a signal and shuts down the associated textile machine. The device can be adjusted for different thread tensions, different thread thicknesses and different knot sizes. To prevent difficulties due to electrostatic charging the main elements of the monitor are connected to a grounding terminal.

  • Graphite fiber alignment process and apparatus
    Patent number: 4271570
    Abstract: Misaligned strands in a graphite fiber on tape are aligned and wound up on reels with a minimum of degradation by the steps of: separating the individual strands, diverging the strands, aligning the strands and winding the individual strands onto separate take-up reels in one continuous operation.Graphite fabric woven from the strands exhibit little or no degradation and have a uniform density and excellent physical properties. The alignment apparatus is inexpensive, simple to operate and occupies a relatively small space.
