Document Type and Number:
Japanese Patent JP2021011377
Kind Code:
A
Abstract:
To avoid a prolonged period of time from when the yarn is split to the time when the yarn is spliced and at the same time restrain the end of the split yarn from being caught into the winding drum.SOLUTION: In an automatic winder 1, when yarn Y is split during a winding process before yarn splicing, a unit controlling part 14 controls a movement mechanism 45 and separates a package P and a winding drum 42 while controlling a drum driving motor 43 to stop the rotation of a wining drum 42 and a breaking part 44 to stop the rotation of the package P. In addition, if the package P stops before the winding drum 42, the unit controlling part 14 controls the movement mechanism 45 so as for the package P and the winding drum 42 to contact again before the winding drum 42 stops its rotation in the timing when the peripheral speed of the winding drum 42 becomes a predetermined peripheral speed or slower.SELECTED DRAWING: Figure 8
