It is also possible to have all or part of the envelope (s) to be heated up immediately before meeting the core thread "so that a certain fixation of the cover thread takes place" it is also possible "to heat the cover thread alone and the To leave the core thread cold. In the latter case, the core thread has no texturing, so that the finished thread has no elastic elongation.

A very irregular effect, which may be desirable under certain circumstances, can be achieved if preferably only one sheath thread is fed in without a delivery device, in which case the rotary movement of the core thread in the false twist zone itself ensures that the incoming thread is drawn off the delivery spool,

When working according to the method according to the invention, has calibration shown a surprising effect. Since also the vertical or sheath thread fed in approximately perpendicular to the axis of the core thread that participates in false twinning in the false twist stretch " it was to be expected that the single threads would form the composite thread after leaving the false twist device would be arranged parallel or essentially parallel to one another, since, as is well known, the thread present in the false twist section again after passing through the false twist spindle dissolves and the thread usually behind the false tweeting spindle has no twist or only the twist it already had when it entered the falsehead stretch. This is ever but surprisingly not the case with the thread according to the invention. Rather, they change in a completely irregular sequence Lengths in which the wrapper or threads in one and run around the core thread in the other direction, also very irregularly, with increasing transmission rate closer spacing strengthens confused areas that have a very loose structure and appear as a kind of kno-> ten appear. When examining the process with the help of a high-speed camera, it was found that the essentially at right angles to the thread axis of the core thread tapering thread just before the point of contact in constantly changing The width of the splice is divided into individual bundles of threads and partly also in its single threads «The point of contact is not fixed at one point« but also introduces « constant upward and downward movement, with the upward moving thread dit at very irregular intervals formed windings partly overtaken, so to speak, and wrapped again in the process Thread observable knots · This phenomenon is special clearly to be observed when a sheath thread is in the frame

The result is a knobbed yarn, which with the knobs formed by the sheath thread at very irregular intervals of different lengths, with the intervening thread lengths. Before the subsequent twisting, the alternating The direction of twist can be seen particularly clearly gives fabricated fabrics a certain elasticity «

With a transmission rate below about 50 % it can be observed that the core thread is deflected in the direction of the converging fadeji; the angle at which the covering thread hits the core thread, however, remains essentially a right one, and the fanning out as well as the migration and migration can still be observed.
