  • Patent number: 6302349
    Abstract: Random wound yarn packages are produced at a winding station of a winding machine having a friction roller for driving the yarn package being wound by: winding yarn onto an initially empty bobbin core with the friction roller to form a finished random wound yarn package; and, during the winding, continuously (i) detecting with sensors a value representative of the angular velocity of the yarn package and a value representative of the angular velocity of the friction roller, and (ii) calculating a value representative of yarn application of the yarn package being wound, which is indicative of yarn package quality, based on the detected values. The yarn application value can be calculated based on a number of revolutions of the yarn package or based on a winding time of the winding process, and the yarn application values can be recorded as a function of time for later reference or display.

  • Patent number: 5954289
    Abstract: A method of producing a random wound yarn package includes driving a yarn package with a friction roller, setting and maintaining a constant yarn tension in the yarn, setting and maintaining a constant contact force between the friction roller and the yarn package being driven thereby, and temporarily regulating the yarn tension and the contact force during a time of a pattern winding zone of the winding process in order to maintain a constant winding density both before and during the time of the pattern winding zone. The winding station includes a friction roller for driving the yarn package, a yarn tensioner, a device that generates a constant contact force between the yarn package and the friction roller, and an evaluation and regulation unit that temporarily regulates the yarn tension generated by the yarn tensioner and the contact force generated by the device during the time of the pattern winding zone.

  • Patent number: 5826815
    Abstract: A yarn package (both conical and cylindrical) is produced at a winding station of a textile winding machine by alternately: accelerating the friction roller driving the yarn package with slippage between the friction roller and the entire surface of the yarn package; and decelerating the friction roller driving the yarn package without slippage between the friction roller and at least part of the surface of the yarn package, e.g., the neutral zone of a conical package. The periods (and thus the frequencies and angular velocities) of the friction roller and the yarn package are detected by sensors which communicate the detected values to a control and evaluation device. Based on the detected values during at least one phase of deceleration, the control and evaluation device estimates the yarn package radius during an acceleration phase.

  • Patent number: 4810892
    Abstract: An element of a machine is provided with a magnetically or optically readable data medium. The data medium is divided into grooves and sectors. A corresponding scanning head for scanning the data medium is arranged on another element of the machine. The data are coded so that it is possible to identify each sector and each groove on the data medium. After reading the contents of the data medium of the element of the machine by the scanning head of the other element, a value of the measurement of the relative positions of the two elements is affected to the data read by the head. This value may be used to control the position of the elements or to displace one of the elements relative to the other. The data medium may be linear or may be configured as a disc. The scanning head may be secured to the associated element. It may also be attached by means of a mechanism so as to have a relative motion with respect to the data medium even when the elements are stationary with respect to each other.
