Definitions

  • the invention relates to a device for drawing and drawing a synthetic thread in a melt spinning process according to the preamble of claim 1.
  • a generic device is from the WO 2011/009497 known.
  • the known apparatus for stripping and stretching a synthetic thread is used in a melt spinning process to draw one or more threads after melt spinning.
  • one or more threads is guided through an array of multiple godets for stripping and stretching.
  • the electric motors of the godets are jointly controlled by an associated control unit.
  • the electric motors are formed by clockwise and counterclockwise motors, which are assigned to the godets alternately.
  • the godets of the godet godet are driven by a left-hand motor and a right-hand motor, both of which are controlled by the control unit.
  • the stretching forces required for stretching are generated by a differential speed, which is adjustable between the godets of the godet duo.
  • the speed difference can be changed by changing the guiding speeds of the godets of the first godet or by changing the guiding speed of the godets of the second godet. Since the known device is used within a melt spinning process, such changes are effective the guide speeds are instantaneous to upstream or downstream thread guides within the melt spinning process. In that regard, a stretching of the threads is possible only in coordination of all treatment steps of the entire process.
  • This object is achieved in that between the godets the godet pair is arranged a single drivable and controllable godet.
  • the invention has the particular advantage that within the melt spinning process, a withdrawal tension generated on a thread is adjustable independently of a drawing of the thread.
  • the deduction of the thread and the stretching of the thread can be advantageously set independently and individually by the godets of the first godet godet and the individually controllable godet.
  • a Vorverstreckung can be realized in which a speed difference is set between the first pair of godets and the individually controllable godet.
  • the draw tension for drawing the thread is essentially determined by the difference in speed between the individually controlled godet and the godets of the second godet tail.
  • the thread can optionally lead in several wraps or with simple Operaumschlingung on the godets of the godets duo.
  • the development of the invention is carried out, in which the electric motors are formed by several anti-clockwise and right-hand motors and in which the following in the yarn course godets are alternately assigned to one of the left-hand motors and one of the clockwise motors.
  • This development is particularly suitable for guiding a plurality of threads parallel next to each other, without long projecting guide coats of godets are required.
  • the development has proven in which the first godet of the first Galettenduos forms a Abzugsgalette with an unheated guide shell, which is smaller in the guide diameter than the guide sheath of the second galette of Galettenduos.
  • This allows a speed difference to be advantageously set between the godets of the first godet tail, which contributes to the stability of the yarn path.
  • an intensive contact after the removal of the thread on the following godets can be realized immediately in order to obtain an intensive thermal treatment of the thread on the heated guide shells.
  • the development of the invention is particularly advantageous in which the electric motors of the two godets of the first godet have a disproportionately large number of pole pairs. This even makes it possible to operate both godets of the first godet in spite of different guide diameter of the guide shells with the same size peripheral speed.
  • the second godet of the first godet tail has a heated guide shell.
  • the thermal treatment of the thread can advantageously be improved by the fact that the godet between the godet godets also has a heated guide shell.
  • the development of the invention is particularly advantageous, in which the godets of the second godet have two heated guide shells, which are formed unequally large in the guide diameter.
  • the associated electric motors can be operated together with a setpoint frequency.
  • the development of the invention is preferably used, in which a godets of the second Galettenduos downstream Relaxiergalette is provided, which is individually driven and controllable. This allows any speed differences to produce stress relief after stretching the thread.
  • the device according to the invention is particularly suitable for drawing synthetic threads for textile applications.
  • fully drawn threads FDY
  • FDY fully drawn threads
  • the individually controlled godets can be preceded or arranged by several godets.
