PURPOSE: To facilitate the initial thread drawing out in the succeeding process by installing a thread reeling-in guide at the position where it does not cross a thread stripe wound on the winding side immediately after the thread is changed over and at the position where it crosses the winding thread stripe formed by the rotation of a turret lathe.
CONSTITUTION: When the thread reeling-in guide 14 moves left, the thread stripe 2 which passes through the traverse fulcrum guide 1, touches the empty bobbin 8, and is wound through the guide 15 moves on the groove 17 of the bobbin 8. Since it is held, it is wound by the cut-off bobbin 8 between its holding section and the winding thread of the bobbin. When the thread is changed over like this, the thread stripe 2 automatically is removed from the thread reeling-in guide 14. Accordingly, no winding mass is formed on the groove 17. It immediately is guided into the screwed groove 18 of the touch roller 4 and forms the prescribed tail, then it starts being rewound. Thus, thread reeling-in guide 14 returns before winding diameter increases.
