  • Patent number: 9639638
    Abstract: Numerical simulation techniques of physical behaviors of a string drawn out of a yarn feeder in a weaving/braiding machine are disclosed. A FEA model, representing a string having a source end at yarn feeder and a braiding end towards braiding/weaving operations, contains at least one truss element with a leading element directly connected to the source end at which pull-out force of the yarn feeder is predefined. Maximum and minimum lengths of a truss element are predefined for facilitating local remeshing. Simulated physical behaviors of the string are obtained by performing a time-marching simulation using the FEA model with the FEA application module having local remeshing capability. Simulated physical behaviors include axial forces in each truss element of the FEA model and the string's deformed geometry. Local remeshing is used for updating the computerized model by creating new leading element that satisfies consistent realistic condition, when local remeshing becomes necessary.

    Abstract: A method and an apparatus for simulating a visual surface pattern of a fiber product and a method and an apparatus for producing a multicolored BCF yarn. In this case, at least one parameter of a strand-like fiber bundle is sensed and is digitized into data which is converted with the aid of evaluation electronics into a surface pattern. The visual appearance of a longitudinal portion of the fiber bundle may be detected as an image as a parameter of the stand-like fiber bundle. A rapid and reproducible simulation of the visual surface pattern of a fiber product is consequently possible. Additionally, the production of the fiber product, for example a BCF yarn, can be monitored by means of the simulation results, so that at least one process parameter can be selected and/or monitored. For this purpose, an image acquisition appliance is provided, which is assigned to a bobbin or to the BCF yarn and which is connected to an evaluation device for an actual-value/desired-value comparison.

  • Patent number: 7299615
    Abstract: A method and apparatus for twisting two or more strands of yarn together in accordance with a pre-selected and changeable pattern so as to obtain twisted yarn with a selected twist level extending for a selected length of the yarn and other selected twist levels and/or twist directions extending for various other lengths of the yarn so that a package of finished yarn has a variable twist pattern which is reproducible and changeable. The yarn twisting apparatus has a drive for pulling the yarn through the twist inserting apparatus, and controllable fluid twisting devices for twisting the yarn together. A programmable controller controls ratios of the speeds at which the product package drive is operated and pressures or other parameters of fluid jets effecting fluid twisting of the yarn. The programmable controller can also vary the time that each selected ratio is maintained.

  • Patent number: 7200983
    Abstract: A supporting disc for a supporting disc bearing of open-end spinning rotors has a disc-like base body, on whose outer circumference a tire-like covering is applied. On a front side of the supporting disc facing the operator's side of the spinning aggregate, a cylinder-shaped permanent magnet for non-contact speed monitoring is arranged at a distance from the axis of the supporting disc. For the purpose of the correction of mass imbalances, the permanent magnet is inserted into a through bore hole, which is filled out by the permanent magnet only up to a gradation of diameters which serves as a stopping surface. As the permanent magnet is arranged in the transition area between the base body and the tire-like covering, the part of the through bore hole not filled out by the permanent magnet can be filled out by the covering.

  • Patent number: 7082746
    Abstract: For the piecing of a yarn in an spinning device, various computation formulas are stored in a control device into which calculated values as well as special data converted into numerical values relating in particular to the fiber material, the yarn and the spinning element are first entered to compute and select settings for operations relevant to the piecing process. A feeding device feeding a fiber sliver to the spinning device is first brought to a high pre-feeding speed by means of such pre-programmed values and converted data. From this pre-feeding speed, the feeding speed is greatly decelerated in steps to its piecing feeding speed in coordination with the release of the yarn to be fed back into the spinning element.
