のである。The yarn switching guide moves the yarn on the yarn layer of the full package to the bobbin end outside the yarn layer forming position, and uses this difference in peripheral speed (the difference in peripheral speed between the package outer periphery and the bobbin outer periphery). It gives slack to the thread. The slackened yarn is entangled with the yarn spun from above on the empty bobbin, so that the winding operation on the empty bobbin can be performed smoothly. A yarn tension is generated between the empty bobbins to cut the yarn. With such a configuration, the transition to the winding operation for the empty bobbin can be automatically performed sequentially after the full package is formed.

In FIG. 2A, when the package Bf becomes full, the yarn Y is removed from the traverse guide 6 of the traverse device 4 by the yarn removal guide, and is held at the center position of the bobbin by the yarn holding guide, and the turret 2 is rotated counterclockwise. Rotate to. Then, FIG.
(That is, the turret 2 is rotated approximately 180 degrees,
After the bobbin holders 15 and 16 are exchanged, the turret 2 is further rotated when the empty bobbin Be is located at the thread switching position M as shown in FIG. 3A. . At this time, the elastic yarn Y is pressed against the surface of the empty bobbin Be, and travels in a state of contacting about 1/3 or more of the entire circumference of the empty bobbin Be. In the following, for the sake of simplicity, the upstream side of the empty bobbin Be of the yarn Y is defined as Yb, and the downstream side of the empty bobbin Be is defined as Ya. In addition, since the yarn Y is removed from the traverse guide 6, the yarn Y is in a state close to the center of the empty bobbin Be and the package Bf.

The yarn switching guide 7 is rotated until a approaches the yarn Yb on the upstream side, that is, until the yarn Y substantially circulates around the empty bobbin Be. In this state, the yarn Y is still wound around the circumference of the yarn layer P of the package Bf. Then, package B
The rotation speed of the bobbin holder on the f side is increased from the set speed during normal winding. This speed increase is such that the difference between the peripheral speed of the outer periphery of the yarn layer of the package and the peripheral speed of the outer periphery of one end of the bobbin is filled, for example, approximately 20% of the set speed during normal winding. Since the yarn Y is a yarn having high elasticity, the tension is increased by the speed increase but is not broken. Note that the speed increase start time may be the rotation start time of the yarn switching guide 7 or the position exchange start time of the bobbin holder, but at least the yarn Y falls from the yarn layer P of the package Bf onto the outer periphery of one end of the bobbin. You need to do it before you let it.
