Abstract

PURPOSE:The stop operation is effected in a low-speed zone to restore the negative pressure in the spinning rotor to an extent of level to reduce the influences caused by fluctuations in the timing of brake and cratch operations, thus increasing the yarn-ending rate on the restart without formation of snarls. CONSTITUTION:When a spinning frame is stopped, the electric current to the driving motor is cut at the time t0 and the feed roller is stopped at the time t1 when the rotation number of the roller comes down to the low speed level. At the same time, the driving motor is started again to increase the rotation number of the spinning rotor. At the time t2 when the rotation is low, the winding- up roller and the taking-up roller are stopped, then the electric current to the driving motor is stopped at the time t3 when the rotation number of the spinning rotor reaches the sufficient one to prevent the snarl formation at the yarn end in the yarn-taking up tube.
