WINDER FOR YARN

PURPOSE:To enable a yarn to be positively trained over a bobbin without changing the tension of the yarn by providing a yarn training guide, a guide path, a support and a drive mechanism for training over the bobbin the yarn wound from a west spool temporarily while the bobbins are interchanged. CONSTITUTION:The rotation of a drive shaft 17 in the direction of arrow R moves a yarn training guide support 13 rightward and swings an end of a stick 14 about a pin 21 so that the moving locus of a guide 16 covers a-d. When the guide 16 reaches point d, the rotation of the shaft 17 is stopped and the stick 14 also moves. The guide 16 further advances to e-g and yarn Y is disengaged from a guide 2 and the upstream side yarn reaches the guide 16 from a guide 1 so that the downstream side yarn is taken up by a spool 4. When the guide 16 reaches h, the upstream side yarn engages a ratchet wheel 9 and is taken up by a empty bobbin 7, a guide 26 and a package. The downstream side yarn is pulled and cut by the ratchet wheel 9 and taken up by the spool 4 so that the yarn training from the spool 4 to the empty bobbin 7 is completed.
