Disclosed is a method for treating a yarn end hanging down from a yarn package which is doffed by means of a doffing apparatus from the winding apparatus after completion of the package winding, and an apparatus for effecting the method. The disclosed apparatus comprises a peg for receiving a doffed full package, a supporting member for rotatably supporting the peg, which peg including a securing member therein for securing a full bobbin held thereon, and a rotating member for rotating the peg with the full bobbin secured by the securing member to the peg, the rotating direction of the peg selected to be a direction which is the same as the rotational direction of the bobbin on the winding apparatus. Utilizing this apparatus, a yarn end hanging down from the full bobbin can be wound back around the full bobbin. Yarn end entanglement, full bobbin damages and damages of the doffing apparatus caused by the yarn end hanging down from the full bobbin can be prevented from occurring. The disclosed apparatus, which is movable in front of the winding apparatus, can vertically displace the peg, swivel the peg within a horizontal plane and tilt the peg within a vertical plane.
