Abstract: A running yarn is severed from a completed yarn package and inserted into yarn collecting means and an empty bobbin having end slots is manipulated to cause the running yarn to occupy the end slots and is then placed in position on a pair of supporting arms which in turn are moved toward driving means while simultaneously a control guide mounted on one of the bobbin supporting arms is manipulated manually from a normal position to an operated position of engagement with the running yarn and held in an operated position while the empty bobbin is rotated sufficiently so as to form a reserve winding at one end of the bobbin following which the yarn control guide is released and caused to swing aside so as to allow reciprocable guide means to engage the running yarn and to cause the yarn to wind evenly on the bobbin from a point adjacent the running winding to a point adjacent the other end.
