  • Patent number: 6279213
    Abstract: A device (6) for holding and centering yam tubes (3) for processing while in a vertical orientation on transport disks (2), e.g., for removing a yam remnant (4) at a tube cleaning station. During such processing, the tubes are fixed in place by means of a height-displaceable centering arbor (12) coupled with a circuit arrangement which causes the operating height (h) of the centering arbor (12) to be automatically matched to the length of the respectively provided tube (3). An arresting arrangement (20) assure that the centering arbor (12) is securely fixed in place at each of its operating heights (h).

  • Patent number: 6092268
    Abstract: Roving residue is removed from roving-bobbin tubes returned from the ring-spinning machines to the roving frame and upon detection of residual roving, that tube which carries a residue is switched with a tube from a magazine containing residue-free tubes. A color sensor detects the color of the tube with the residue to be removed from the train and a tube of corresponding color is positioned at the changeover station of the magazine. The colors and positions of the tubes in the magazine can be stored in data storage or a color sensor can detect the color of the tube in the magazine at the changeover position.

  • Patent number: 5884468
    Abstract: A device for centering tubes during their processing, for example in a tube cleaning station of a textile machine. In a textile machine provided with several batches of tubes of differing length, diameter and/or material, which cannot be processed together in known cleaning devices, the present device has a rotatably seated holder with at least two differing centering devices adapted for different tubes for selective positionability relative to the tubes to be centered according to sensor devices which detect the differing physical characteristics of the tubes.

  • Patent number: 5732544
    Abstract: A yarn remnant removal system for flexible textile yarn tubes deflects the textile yarn tube inwardly in order to effectively reduce the tube circumference and loosen the yarn remnants wrapped thereon. The system provides for a tube receiver over which a textile yarn tube is placed and a deflection arm or blade which operates to engage and deflect the textile yarn tube inwardly while the tube rests on the tube receiver. Preferably, the tube receiver will include vacuum cups for providing a vacuum to engage a deflected portion of the textile yarn tube and to hold the textile yarn tube in an inwardly deflected state. The textile yarn tube remains deflected after the deflection arm is released. Multiple jets of air may be used to blow the yarn remnants from the textile yarn tube and the tube receiver may be rotated downwardly into a vertical position to further facilitate remnant removal.

  • Patent number: 5179769
    Abstract: Apparatus for assuring complete stripping of fibers from a bobbin in a bobbin stripping system includes a bobbin stripping station including oscillating water jets, a viewer to view bobbins as they are being stripped at the stripping station and to generate signals representative of a bobbin being stripped. A water jet position sensor generates a signal indicative of whether the position of the water jets is such that the viewer's view of the bobbin is unobscured. An indexing conveyor moves fully stripped bobbins from the stripping station and unstripped bobbins to the bobbin stripping station. A bobbin transport sensor generates a signal when the indexing conveyor is moving a bobbin to or from the bobbin stripping station. A computation device selects pixels of the signals from the viewer, counts a first number of pixels indicative of fibers and a second number of pixels indicative of bobbin.
