Abstract (en)

[origin: CN111441114A] The invention relates to a method and a spinning machine for inserting a false twist into a thread (7), wherein a thread running plane (20) is formed by the course of the thread (7) directly through adrafting device (3) to a large extent in plan view up to the spinning machine and the thread (7) exits the drafting device (3) at an output clamping point (6) formed by an upper roller (4) and/or a lower roller (5). The thread (7) is operated between the output clamping position (6) and the spinning position by means of a roller (8) which rotates about an axis of rotation (15) that is oblique tothe thread running plane (20). The thread (7) is rotated about its longitudinal axis at the same time and a first false twist is inserted into the thread (7). The thread (7) is moved laterally out ofthe thread running plane (20) by means of the roller (8), and the thread (7) is brought into contact with the upper roller (4) and/or the lower roller (5) after the output clamping position (6) in such a way that the upper roller (4) and/or the lower roller (5) inserts a second false twist into the thread (7). The device for inserting a false twist into a thread (7) on a spinning machine comprisesa device support (21) for fastening a roller to the structure of the spinning machine.
