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.
Apparatus for winding yarn on an empty bobbin so as to form a reserve winding having an accessible end at one end of the bobbin, said apparatus comprising yarn feed means for continuously feeding a running yarn, yarn collecting means for receiving and collecting a running yarn fed by said yarn feed means, a pair of pivotally mounted spaced apart bobbin supporting arms each having a bobbin supporting flanged roller rotatably mounted thereon for respectively engaging the ends of a bobbin having axially extending angularly spaced slots formed in one end thereof and extending inwardly by a distance farther than the distance by which the associated roller projects into the bobbin so that yarn from said yarn feed means may pass inwardly through one of said slots and outwardly through the other of said slots, means for rotating the bobbin, a reciprocable guide disposed to receive the running yarn from said yarn feed means and effective to cause the yarn to wind evenly along the bobbin, and a yarn control guide movably mounted on one of said bobbin supporting arms and movable from a normal position to a position of engagement with the running yarn from said yarn feed means so as to hold the running yarn clear of said reciprocable guide in order to form a reserve winding having an accessible end at one end of the bobbin.
A method of winding yarn on an empty bobbin having yarn receiving slots at one end so as to form a reserve winding having an accessible end at said one end of the bobbin, the method comprising feeding a running yarn into yarn collecting means, threading the running yarn through the slots in the bobbin, mounting the threaded bobbin on a pair of spaced apart bobbin supporting arms, rotating the bobbin, engaging the running yarn being fed into said collecting means and holding the running yarn in a position of transverse alignment with a part of the bobbin which is near said one end thereof so as to cause the running end to form a reserve winding thereon;
