  • Publication number: 20170137975
    Abstract: The invention relates to a method for the resumption of the spinning process on an air-jet spinning machine, in which after an interruption in the spinning process has occurred, yarn (5) is guided back to its working path behind a spinning nozzle (4), or the yarn is stopped in a controlled manner in the working path with the end of yarn behind the spinning nozzle, the end of yarn (5) being introduced to the outlet opening (41) of the spinning nozzle (4), whereupon the yarn (5) is transported by a reverse motion by means of the spinning nozzle (4) and a feeding device (3) of sliver (0) as far as to a guide channel (2) before the spinning nozzle (4), where on the yarn (5) in the guide channel (2) a spinning-in end of yarn is formed and the yarn (5) reserve starts to be created in an underpressure yarn storage device (73) in front of the winding device (9) of yarn.

  • Patent number: 9353463
    Abstract: A spinning point of a spinning machine includes a spinning unit, a drawing-off device for the yarn downstream of the spinning unit and a yarn storage downstream of the drawing-off device for the intermediate storage of a section of yarn. The yarn storage has a sensor system for monitoring the filling level of the yarn storage (7). The spinning point includes a winding device for the yarn downstream of the yarn storage, along with a return unit, with the assistance of which an end of the yarn found within the yarn storage after a yarn break is returned into the area of the spinning point. The winding device (9) is stopped in the case of a yarn break in such a manner that, after the stop, an end section of the yarn remains within the yarn storage (7).

  • Publication number: 20150175380
    Abstract: The invention relates to a method for removal of yarn (0), especially faulty yarn, from an inter-storage at an operating unit of a textile machine, in which the yarn (0) which is to be removed from the drum (1) of the drum inter-storage is moved from the drum (1) by the force (F) exerted in the direction of the longitudinal axis (A) of the drum (1) towards the end of the drum and/or outside the drum, from where the yarn (0) is sucked off. The invention also relates to a device for removal of the yarn, especially faulty yarn, from a drum inter-storage of yarn at an operating unit of a textile machine, where the drum inter-storage comprises a drum (1) with a working surface (10). The working surface of the drum (1) is assigned with power means for moving the yarn (0) from the drum (1) by force (F) exerted in the direction of the longitudinal axis (A) towards the end of the drum (1) and/or outside the drum (1), where the drum (1) is assigned with suction pipes (2) of the yarn.

  • Patent number: 8931249
    Abstract: A method interrupts yarn production on a spinning machine having at least one spinning point having an inlet for a fiber material and an outlet for the yarn made from the fiber material, and wherein the spinning machine comprises a delivery device for feeding the fiber material into the spinning point, a take-off device for drawing off the yarn out of the spinning point, a winding device for winding up the produced yarn, and a yarn monitoring unit for monitoring at least one yarn parameter. Yarn production is interrupted upon detecting a defined deviation of the monitored yarn parameter from a target value, upon changing bobbins at the winding device, and/or prior to switching off the spinning machine.

  • Patent number: 8919091
    Abstract: A method is provided for interrupting yarn production on a spinning machine upon detecting a defined deviation of a monitored yarn parameter from a target value, upon changing bobbins at a winding device, and/or prior to switching off the spinning machine. The feed speeds of the delivery device, the take-off device, and the winding device are gradually reduced to a stop in order to interrupt the yarn production, wherein the reducing takes place such that an end of the produced yarn is located within the spinning point after the reducing is completed.
