  • Publication number: 20150113777
    Abstract: An assembly and method for automated cutting of undesired stretched yarn in a yarn system. Stretched yarn can hang away from the yarn system differently than desired yarn. A cutter head is positioned a predetermined distance relative to yarn traveling through the yarn system so that the stretched yarn is cut by the cutter head and the desired yarn passes the cutter head without being cut. A plurality of cutter heads can be used to cut stretched yarn hanging away from the yarn system in different locations.

  • Publication number: 20130313484
    Abstract: An anti-counterfeiting fiber, anti-counterfeiting paper containing the anti-counterfeiting fiber, and manufacture method thereof. The anti-counterfeiting fiber is a slice or part of a slice cut along a cross-section of a strip-shaped fiber, wherein the strip-shaped fiber includes a specific structure along the length direction providing anti-counterfeiting characteristics. Structures manufactured using the principles of the process have better orientation than structures manufactured using conventional processes for manufacturing anti-counterfeiting fiber during the paper manufacturing process and can form more unique visual characteristics.

  • Patent number: 6499345
    Abstract: The invention relates to a measuring device for thread-like test samples (3), comprising a measuring slit (2) exhibiting measuring areas (6, 7) for measuring characteristics of a test sample which moves longitudinally, said measuring areas being associated to a measuring device. A coating (8) made of an abrasion-resistant material is applied over the whole measuring slit and its measuring areas (6, 7) in order to define more freely the dimensions of said measuring slit and especially to obtain a narrower measuring slit.

  • Patent number: 5758482
    Abstract: An apparatus and method for interrupting delivery of sliver to a spinning frame for spinning sliver into yarn and winding the yarn onto a spindle utilizing a sliver stop motion. The sliver stop motion is positioned on a respective drafting system of the spinning frame. The sliver stop motion is mounted to the spinning frame so as to overlie the back drafting rolls for stopping the motion of sliver being drafted by the back drafting rolls responsive to a break in yarn being wound onto the spindle. The stop motion includes an elongate pivoting member which is pivotally mounted to a frame mounting member. The frame mounting member is pivotally mounted to the spinning frame. At the stop motion's proximal end, a yarn contact member extends outwardly therefrom so as to underlie and slidably contact yarn being directed to the respective spindle. A sliver comb is connected to and extends outwardly from the distal end of the elongate pivoting member so as to overlie sliver being drafted by the back drafting rolls.

  • Patent number: 5537811
    Abstract: A method and apparatus for simultaneously cleansing and grading yarn produced by a spinning or spooling machine with a plurality of spindles or primary spools. One spindle processor is associated with each spindle. The spindle-processor grades in a grading plane containing a cleansing envelope. All yarn defects located outside the cleansing envelope in the grading plane are considered unacceptable defects and are excised from the yarn.

  • Patent number: 4036445
    Abstract: A circuit arrangement for monitoring the operation of an electronic yarn clearer on an automatic yarn winding machine and particularly for monitoring the operation of the output relays and yarn cutting device of the yarn clearer. Logic circuitry is provided for combining the output signals of the yarn clearer circuitry and produces control and/or alarm signals when the cutting device fails to sever the yarn upon appearance of a cutting pulse, i.e. when a yarn travel signal is permanently present during a predetermined time interval commencing with the start of said cutting pulse.
