Document Type and Number:
Japanese Patent JP3147816
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the success rate of a yarn delivery from a full bobbin to an empty bobbin and prevent the damage of a yarn in the case of its changing over.
SOLUTION: A spinning yarn winding machine has a changing motion for changing over two bobbin holders 15, 16 to a winding position (a) and a standby position (b), and in the case of delivering a running yarn Y to arrive at the full bobbin FB to an empty bobbin EB with the changing motion, a yarn path control guide 21 for controlling a contact angle at which the running yarn Y comes into contact with the empty bobbin EB at the time of a changeover motion is provided in the winding machine, and the yarn path control guide 21 is controlled so that a contact angle from the time when the running yarn Y comes into contact with the empty bobbin EB to the time of a yarn delivery may be maintained smaller than contact angle at the time of yarn delivery.
