Document Type and Number:
WIPO Patent Application WO/2019/035293
Kind Code:
A1
Abstract:
According to the present invention, a winder unit is provided with a winding part, a package driving motor, an upper yarn capturing pipe, and a unit controller. The winding part forms a package by winding yarn. The package driving motor drives the rotation of the package, and can switch the rotation direction. The upper yarn capturing pipe captures the yarn from the package rotated in a reverse direction to the yarn winding direction by the package driving motor. The unit controller controls the rotation direction of the package, and the starting and stopping of the rotation. According to the rotational inertia of the package, the unit controller changes the timing of an instruction for stopping a reverse rotation, which is the reverse-direction rotation of the package with respect to the package driving motor, and the timing of an instruction for reducing the speed of the reverse rotation in order to stop the rotation.
