Abstract (en)
[origin: EP0875480A1] To provide a take-up winder and related yarn-transferring method that can improve the success rate of yarn-transferring from a full bobbin to an empty bobbin without damaging the yarn during transferring. The present invention has a switching operation that switches two bobbin holders 15 and 16 between a winding position (a) and a standby position (b), and provides a yarn path restraining guide 21 that controls the angle at which a travelling yarn Y leading to a full bobbin FB contacts a empty bobbin EB when the travelling yarn Y is transferred to the empty bobbin EB in response to the swithcing operation. The yarn path restraining guide 21 is controlled in such a way that the contact angle from the contact of the travelling yarn Y with the empty bobbin EB until the yarn-transferring operation is maintained smaller than the contact angle during yarn-transferring. <IMAGE>
