A pair of draw-off rollers (10, 11) of a thread drawing-off device comprising an over-mounted pressure roller (11) which cooperates resiliently with a driven roller (10) which projects across the front of the pressure roller (11). The pressure roller (11) has at least one recess (113, 114) on its front face (110) which is dimensioned in such a way that it temporarily completely releases a thread (4) sliding along the surface of the driven roller (10) and lying adjacent to the front (110) of the pressure roller (11). By means of a device of this type, the thread (4) is drawn off, for the purposes of joining, to such an extent from the spool (31) that the thread (4) reaches the side (310) of the spool (31) which is facing away from the front (110) of the pressure roller (11) provided with recesses (113, 114). The thread is then introduced into the spinning chamber (2) and is joined. The thread is then guided, using the thread tension, past the front (110) of the pressure roller (11) provided with recesses (113, 114) and introduced into the clamping line of the pair of draw-off rollers (10, 11) and is immediately subjected at this point to a predetermined draw-off.
A thread drawing-off device for an open-end spinning device having a pair of draw-off rollers comprising an over-mounted pressure roller which cooperates resiliently with a driven roller projecting across the front of the pressure roller comprising:
A method of inserting a thread being wound on a spool of a take-off device in the clamping line between a pair of draw-off rollers including a pressure roller and driven roller after said thread has been joined to thread being produced in a rotor of an open-end spinning device, said method comprising the following steps:
