  • Such jobs are usually also each equipped with a lower thread sensor, a thread tensioner, a thread cleaner with thread trimming device, a yarn tension sensor, a thread catching nozzle and often with a paraffining device.
  • Fadenspl facedvorraum and thread handling devices in the form of a pivotally mounted, underdruckbeaufschlagbaren suction nozzle for the upper thread and a pivotally mounted, also undertikbeaufschlagbaren gripper tube for the lower thread.
  • the suction nozzle and the gripper tube are usually connected to a machine-length vacuum crossbar and ensure that if necessary accumulated on the cross-wound bobbin or fallen onto the supply bobbin thread ends are transported to Fadensleiißvorraum.
  • Fadenleitkanal that is, the area of the yarn path so that the thread runs during Umspulvorganges in a relation to the environment largely closed shaft.
  • the jobs each have a thread running path enclosing, multi-part Fadenleitkanal extending between the Abspul ein a supply bobbin and the winding device of the workplace.
  • the thread guide which can be acted upon by negative pressure, if necessary, are a plurality of receiving housing or receiving sections for different thread monitoring and treatment facilities integrated.

  • Fadenleitkanals Fadenansaug has a suction head receiving housing to which a Saug Kunststoffstutzen is connected. To the suction head receiving housing further a limited pivotally mounted suction head and a positionable in various positions control flap are connected.
  • the jobs are each equipped with a device for connecting a connected to a package upper thread and an associated with a drain bobbin lower thread.
  • the workstations each have a workstation computer for controlling the connection process, a first suction nozzle for receiving the upper thread and a second suction nozzle for detecting the lower thread.

  • the suction nozzle head part is in each case arranged in the region of the winding device of a workstation such that a suction slot is positioned in the region of a take-up bobbin located in the winding device. If necessary, the tubular connection part can be separated from the suction nozzle head part and swiveled such that an upper thread taken up by the first suction nozzle is transferred into a thread connecting device.

  • the thread suction device according to the invention has the advantage that, with such a design, an optimization of the suction air flow pending in the area of the thread suction device is possible.
  • the upper form sheet is pivotally mounted. If, in addition to the lower movable forming sheet, the upper forming sheet is also designed to be movably mounted, then both forming sheets can be positioned individually in the vicinity of the surface of the rotating package and the thread registration of an upper thread accumulated on the package is further optimized.
  • the two shaped sheets can be controlled independently of one another. In this way, it is easily possible, if necessary, for example, because the results of recording the thread end of the upper thread do not meet the desired requirements, even subsequently interfere with the final position of the form sheets control technology. For example, it is possible for the distance of the front edge of the upper shaping plate as well as the distance between the front edge of the lower forming plate and the surface of the package to be subsequently corrected in the sense of improving the upper thread take-up.

  • the upper forming sheet is always positioned during the regular winding operation in an upper working position in which the leading edge of the forming plate is adjacent to the rotating surface of the package.
  • Such a positioning of the molded sheets ensures that in the case of a yarn break or a controlled thread cleaner cut the high-impact end of the thread can not be thrown next to the bobbin.
  • the upper mold sheet ensures that the thread end of the upper thread remains in the region of the surface of the package and can be subsequently resumed without problems by means of the thread suction device according to the invention.
