Definitions

  • the false twist device is formed from a single belt.
  • the two Riementrums have the same amount of speed, but they are running in the opposite direction. While in these embodiments, the interference of the false twist device by different shapes, speeds or arrangements of the two belt spins of the single belt is very limited, is in the further embodiment according to Figure 8 or in the embodiment of Figure 9, a false twisting device provided with two belts. In this case, however, the belts are arranged in a circle, wherein the thread is located between the two belts. Although this arrangement is variable, but it is limited to a single spinning station and thus implement very complicated to a spinning machine structurally.
  • At least one of the two belts or belt rums of the false twist device is guided along several of the spinning units of the spinning machine.
  • Several spinning units form part of the entire spinning machine.
  • the belt which is guided along several of the units of the spinning machine, requires only one drive for several spinning units.
  • the second belt can either also be guided along several units of the spinning machine or it can also be provided per spinning unit.
  • the two belts can also be assigned to a different number of spinning units. Through this different length versions of the belt, the cost of the construction of the false twisting device can indeed be higher, but it is also possible with respect to a greater variability. The setting on different spinning units.
  • the thread is guided in such a way and the false twisting device is arranged such that it wraps around at least one of the two belts by more than 90 °, preferably by more than 110 °.
  • the second belt lies substantially in the same horizontal plane as the first belt and the yarn is then further withdrawn obliquely downwards from the false twist device. Due to the high wrap around the false twist effect is particularly well introduced into the thread.
  • the belts are advantageously designed such that they have a round or a rounded cross-section.
  • the thread can optimally invest in the belt and the rotation initiation by the belt in the thread can thus be done very well.
  • the belt 4 per machine side or sectioned be executed.
  • the inner belt 5 may also revolve around the entire machine while the outer belt 4 is split.
  • the representations of the Figures 2 . 3 and 4 not the complete spinning machine 10, but only a partial sections such as a section 17.
  • Their Falschdrall sensible 9 are operated independently.
  • the pair of output rollers 2 of a drafting system can also be another component, with which the thread 3 of the false twisting device 9 is supplied.
