ABSTRACT:
A method and apparatus is disclosed for serially winding a high speed running yarn onto bobbins without yarn stoppage between bobbin changes, and without loss of yarn. The method and apparatus includes at least two bobbin receiving chucks which are adapted to be serially delivered to a winding position. When the first bobbin becomes full, it moves laterally away from the yarn traverse guide, and the chuck with an empty bobbin and an associated yarn catching notch is moved into the yarn path of travel while being rotated, and with the notch being positioned axially outside the yarn traverse stroke along the empty bobbin. The separated full bobbin, which continues to receive the yarn, is then moved axially so that an end portion is aligned with the plane of the yarn catching notch on the empty bobbin. An auxiliary yarn guide is then moved to engage the yarn and terminate its traverse. The auxiliary guide then moves the yarn into the plane of the yarn catching notch, and so that the yarn is wound on the axially extended end portion of the full bobbin, until the notch catches the yarn, at which point the yarn commences to be wound upon the rotating empty bobbin. The auxiliary yarn guide then releases the yarn so that it is caught and again traversed by the traverse guide.
