Definitions
- the invention relates to a method for the alternative application of either an S-twist or a Z-twist to a yarn, according to the preamble of claim 1. Furthermore, the invention relates to a device for false twist texturing with several twist generators driven in the same direction in the same direction for acting together on a continuous yarn of claim 6, wherein this device can also be suitable for performing the aforementioned method.

- this unit can be designed such that the axis of rotation of the rear or central swirl sensor, for example, forms the fulcrum for one swivel element of further left and right swirl sensors.
- the unit is removed from the receiving device.
- a locking element inserted between pivoting elements and receiving device is actuated for unlocking, after which the pivoting elements can be pivoted.
- the swivel element which carries the left swirl generator is brought into the previous position of the right swirl generator about the axis of rotation of the rear or middle swirl generator.

- the large number of individual swirl generator units is coupled to a common drive source, for example tangential drive belts.
- a slight decoupling from the drive source is desirable.
- the receiving device is attached to a bracket on the textile machine side via a bearing point which permits linear displacement and / or rotation. The linear offset or rotation then serves to bring about the coupling and / or decoupling in the desired S or Z swirl drive direction.
- This design is particularly advantageous in the case of drive coupling via one or more whorls of a swirl generator unit, which are in frictional engagement with a continuous tangential drive belt as a common drive source.
