    Abstract: The method is used for the automatic operation of a ring spinning system (1) which contains a ring spinning machine (2) having a plurality of spinning positions (21) and a winding machine (3) having a plurality of winding positions (31). Yarn (92) is spun at one of the spinning positions (21) and wound up to a cop (91). For the spinning position (21), values of a parameter characteristic for the operation of the spinning position (21) are determined during the winding of the cop (91) and stored as spinning data. The spinning data are assigned to the cop (91). The cop (91) is set down from the spinning position (21). The spinning data assigned to the cop (91) is taken into account when deciding whether to feed the cop (91) after it has been set down to one of the winding positions (31). The automatic assignment is based on an identification of a point in time of winding of the cop (91) and an identification of the spinning position (21) at which the cop (91) was wound.

    Abstract: The method is used to operate a ring spinning system (1) which contains a ring spinning machine (2) having a plurality of spinning positions (21) and a winding machine (3) having a plurality of winding positions (31). Yarn (92) is spun at one of the spinning positions (21) and wound up to a cop (91). Values of a spinning parameter are determined at different times during the winding of the cop (91) and stored as spinning data. The cop is transported from the spinning position (21) to one of the winding positions (31). At the winding position (31) the yarn (92) is rewound from the cop (91) onto a yarn bobbin (93). Values of a yarn parameter are determined at at least two different times during the rewinding of the cop (91) and stored as yarn data. The spinning data and the yarn data are automatically assigned to each other in such a way that they relate to the same yarn section. Based on the spinning data and yarn data assigned to each other, an intervention is made on the ring spinning machine (2).

  • Patent number: 8959002
    Abstract: Readings of a characteristic of the yarn along the longitudinal direction of the yarn are detected. Values of a yarn parameter are determined from the readings. An event field contains a quadrant of a two-dimensional Cartesian coordinate system, whose abscissa defines an extension of yarn parameter values in the longitudinal direction and whose ordinate defines a deviation of the yarn parameter from a desired value. Densities of events in the event field are determined from the values of the yarn parameter and their extensions in the longitudinal direction. A yarn body is represented as an area in the event field. The area on the one hand is delimited by the abscissa, on the other hand by the ordinate and further by a line in the event field that substantially follows a constant event density. The representation of the yarn body permits a clearing limit to be defined in a rapid and rational manner.

  • Patent number: 8957688
    Abstract: An apparatus for determining at least one dielectric property of a capacitor arrangement, and especially for capacitive examination of a moving elongated test subject such as yarn. It contains an alternating signal generator for applying an electric alternating signal to the capacitor arrangement. The capacitor arrangement is uncoupled from the alternating signal generator by means of an amplifier in such a way that it does not relevantly influence the basic frequency and the signal shape of the applied alternating signal. Detection means detect an electric measuring variable of an electric signal tapped from the capacitor arrangement. The alternating signal generator is set up in such a way that at least one of the basic frequency and the signal shape of the applied alternating signal can be changed.

  • Patent number: 8875897
    Abstract: An apparatus for processing a sample including fibers and trash, having a cylinder rotating in a first direction for receiving the sample. The cylinder has a surface with rigid pins. The pins engage and retain the fibers of the sample. A collection surface receives the trash that falls from the cylinder. A counter-flow of air moves in a separation region between the cylinder and the collection surface in a direction that is substantially perpendicular to and towards the underside of the cylinder. The counter-flow of air has at each position within the separation region an air-flow velocity that is sufficient for the counter-flow of air to blow the fibers that are not originally retained by the pins up toward the cylinder and thereby engaging the fibers with the cylinder, and yet insufficient to prevent gravity from pulling the trash downward through the counter-flow of air.
