A method of yarn (7) loop (71) consumption after yarn (7) spinning-in on a rotor spinning machine on which the spinning-in process takes place at full operation speed with the bobbin (112) set out of contact with its driving roller (111). The bobbin (112), after being spun-in, is set in contact with the driving roller (111) and thus set in rotary motion in the winding sense, then the bobbin (112) is set out of contact with the driving roller (111) and accelerated to a circumferential velocity superior to the operation winding velocity, then the acceleration to said superior circumferential velocity is stopped, the bobbin (112) is reset in contact with the driving roller (111), thus reduced to said operation winding velocity, and the size of the loop (71) of the yarn (7) due to the overproduction of yarn (7) at the start of the rotary motion of the bobbin (112) is thus reduced. |
