ABSTRACT:
A winding machine winds threads upon a package. The machine includes a thread change mechanism for positioning the threads relative to the package. The thread change mechanism includes a thread guide member having first and second longitudinally spaced ends. The guide member is mounted for swinging movement relative to a housing of the machine by means of two swingable levers. One end of each lever is attached adjacent the first end of the thread guide member. A servo-motor is operably connected to one of the levers for swinging the thread guide member. A power transmission operably interconnects the first and second ends of the guide member for positively transmitting a swinging motion of the first end to the second end in order to effect synchronous swinging movement of the first and second ends. A limiting device retains the guide member in a thread change position but allows the guide member to be moved past the thread change position to a thread drawing-in position.
