Abstract (en)
[origin: WO9836115A1] The invention relates to a method of individual spinning-in of yarn (32) at an operating unit of a rotor spinning machine in which on a lifted bobbin (92) there is first manually detected the end of the yarn (32), manually metered out the yarn (32) length required for carrying out the spinning-in process, and at the end of the yarn (32) is formed, and then introduced into a delivery tube (15) of the spinning rotor (14), a spinning-in end of the yarn (32). Prior to being spun-in, the yarn (32) is led into its travel path at the operating unit of a rotor spinning machine and passes through a draw-off mechanism, i.e., between a draw-off roller (41) and a pressure roller (43) tilted away from the draw-off roller (41), is deflected from its travel path by at least one deflecting means (10, 20) of the operating unit of the spinning machine while passing outside the distribution mechanism (8) whereupon the deflecting member (10, 20) is released and due to this the spinning-in end of yarn (32) comes onto the collecting groove (141) of the spinning rotor (14) on which prior to this there was formed a fibre band (31) beginning then to join it whereupon, at a predetermined time interval after the yarn (32) spinning-in end has come onto the collecting groove (141) of the spinning rotor (14), the draw-off mechanism (4) of the operating unit of the spinning machine begins to draw off the yarn (32), and the winding mechanism (9) of the operating unit of the spinning machine begins to wind it. Preferably, the quality and presence of the yarn (32) is monitored at least in front of the draw-off mechanism (4).
