PURPOSE: To avoid less efficiency by braking a cross-wound package at rest during occurrence of a yarn defective portion, cutting yarn thereafter to remove the yarn defective portion and forming a knot or splicing joint to start winding. CONSTITUTION: When a yarn monitor 10 detects that a defective portion occurs in running yarn 3, a controller 43 turns off a motor 25 and actuates rapid braking devices 50, 51 to put a winding drum 12 and a cross-wound package 14 at rest. After they are at rest, the yarn 3 is cut by a yarn cutter 9, the yarn defective portion is removed, a knot or a splicing joint is formed instead of the yarn defective portion and then the braking devices 50, 51 are released to start the motor 25 for winding operation. In this way, the less efficiency of an automatic winder due to the occurrence of the yarn defective portion is minimized.
