Since the operation of the fixing means A5 and / or the fixing means B6 can be appropriately changed according to the state, the target yarn end processing is always performed reliably and automatically. Further, the defective yarn package 43 determined to be unprocessable by the change of the operation is removed in advance without performing the yarn end processing. Accordingly, a high processing success rate is maintained, and the defective yarn package 43 is maintained.
(I.e., the winding of the yarn end around the processing device) is prevented, thereby improving the productivity and stabilizing the operation of the apparatus.

Further, in the above embodiment, the tail treatment (fixing means A5) and the surface treatment (fixing means B6) are performed in this order, and the tail treatment (thread end fixing) that is easily broken is performed on the upstream side. In addition, when the yarn package 2 is operated at the surface treatment position on the downstream side, it is possible to prevent a problem that the tail yarn is broken. Further, when performing the surface treatment, the disturbed tail yarn does not become entangled with the surface yarn and does not hinder the surface treatment. As a result, reliable processing becomes possible, and processing efficiency is further improved.
