ABSTRACT:
An improved method and apparatus for automatically changing bobbins and winding yarn continuously in a winding or taking-up apparatus provided with a rotatable turret whereon a pair of bobbin holders are rotatably mounted. Each bobbin utilized for this apparatus is provided with a yarn catching groove formed on a peripheral portion thereof. When the bobbin exchanging operation is carried out, the turret is turned in a direction opposite to the rotational direction of fresh and full packaged bobbins held by the corresponding bobbin holders so that the yarn passed through a traverse guide of the apparatus is aligned with the yarn catching groove of the fresh bobbin whereby the yarn is engaged with the above-mentioned yarn catching groove.
