The flowing Nediua is essentially tangential to the inner circumference of the curved concave surface. or in a plane which forms an angle of up to about 75 ° with this vertical in order to exert a driving or braking effect on the Oarn in addition to the rotary effect. Several cannulas can be provided to guide the flowing medium around the circumference of the concave surface, and these supply canals can be arranged at intervals along the Oarndurohlasse and / or around it. However, if several supply ducts are arranged, they should all run in essentially the same tangential direction in order to give the Oarn the greatest torque.

eelung su achieve * It is important that the tension of the yarn subjected to the twisting of the working medium is kept below about 15 g. This low tension in the yarn can be controlled by means of a tension gate or other suitable devices. Usually and preferably the low tension is achieved using feed and winding rollers, the rollers being operated so that the yarn is at a higher speed Twist fed in than withdrawn from it · The difference between the speeds of the orange feed and the orange draw is determined by the usual degree of volume as well as the relative working speed, ie the throughput in a / min. The oil wind speed difference between the yarn feed to the twister and the yarn take-off from the same can be between about 5 and 50 % and the speed at which the yarn is guided through the working twister can be 0 to about 595 m / min or more Oarnesole winds usually at least about 91, preferably at least about 18-5 n / min.

This applies to the execution of the inventive method for the creation of a usable voluminous or Stretoh-Oarne essential «that the work! leaving the twisted back yarn on a suitable for backwashing Pack is wound up. Winding up must be done under a substantial amount of Oarn tension; preferably

tends to promote instability of treatment «in particular if the Oarn tension is very low (less than about 2 g). A careful setting of the kind «that the Oarnaohse at the places where the Qarn enters the twisting machine and leaves it with the axis of the exiting air stream β corresponds, results in a much more stable and equal work welfare, and la case of work equipment " twists, which in comparison to neo-hanical twisting devices Having such a high effectiveness is a stable way of working and the achievement of uniform properties to prefer an optimal degree of efficiency in the product. Because the adjustment of the threadline to the exiting air flow is difficult without mechanical aids, nan good by the following method procedure A free OarnstUok is inserted into the twister in such a way that a piece of perhaps 15 cm protrudes on both sides of it · Then the air supply is turned on and the position of the free oarn ends observed. It is now relatively easy to arrange guides in such a way that they are flush with the position of the free ends that the running thread then travels the same way. This direction of the grain is particularly behind important to the twister.
