ABSTRACT:
A method and apparatus for finding and feeding a yarn end to be taken up in a textile winder in which bobbins in an upright disposition on individual tube support members are advanced sequentially to a winding position. A detector determines whether yarn is being unwound from the bobbin the winding position. If the detector detects that no yarn is being unwound, a yarn finding device locates with suction the yarn end on the bobbin in the ready position next succeeding the bobbin in the winding position. The finding of the yarn end is assisted by an air blowing device. A yarn feeding device feeds the yarn end to a yarn joiner to be joined to the trailing yarn end from a take-up yarn package, or places the yarn end on an empty take-up package tube. The yarn finding device employs an open end yarn end receiving portion, which applies suction to the upstanding end of the bobbin in the ready position. The yarn end receiving end portion is adjustable to accommodate bobbins of different lengths and has a slot through which the found yarn passes to feed to the take-up as the bobbin moves to the winding position. A balloon breaker has mounting positions extending from the yarn end receiving end portion on opposite sides of the slot to guide the yarn into the balloon breaker above the winding position.
