PURPOSE:To make it possible to stop and restart an apparatus for preparing bound spun yarns without causing broken yarns in stopping the apparatus at one time, by stopping a drafting part, taking-off part and winding part at the same time, and stopping the operation of a false twisting part and a pneumatic part simultaneously with or after the stopping. CONSTITUTION:In stopping the respective spindles at one time in an apparatus for preparing bound spun yarns consisting of a drafting part 2 having rollers and aprons (2a), a pneumatic part 3 for sucking fibrous groups having a rubber pipe 4 and a pneumatic duct 5, a false twisting part 7, a taking-off part 11 and a winding part 12 without causing broken yarns, the function of a yarn breakage sensor 13 is first stopped, and the drafting part 2, taking-off part 11 and the winding part 12 are simultaneously stopped. The false twisting part 7 and the pneumatic part 3 are stopped simultaneously or after the stopping. The restarting operations can be carried out in the reverse order without causing the yarn breakage. |
