PURPOSE:To obtain the smooth operation of a reversing device for a cradle supporting both ends of a bobbin in a winder by driving a cradle support shaft with a bobbin holder rotatably fitted through engagement of gears by a regular/ reverse driving shaft. CONSTITUTION:A captioned device is composed of a cradle support shaft 3 and a pair of bobbin holders 4 rotatably fitted therein. In this construction, a regular/reverse drive shaft 1 is provided for fast fixing a gear 2 partly toothed. A partly toothed gear 6 is also fixed on the support shaft 3, and at the top of this gear 6, a plane part 7 is provided to push up a pin 5 of the bobbin holder 4. Thereby, when thread is fully wound up on the bobbin, the regular/reverse drive shaft 1 is reversely rotated at a required angle, the above-said two gears 2 and 6 are engaged, the cradle support shaft 3 is regularly rotated, the plane part 7 pushes up the pin 5, and the bobbin holder 4 is regularly rotated at a fixed angle for stopping. |
