PCT No. PCT/KR96/00124 Sec. 371 Date Mar. 30, 1998 Sec. 102(e) Date Mar. 30, 1998 PCT Filed Jul. 29, 1996 PCT Pub. No. WO97/04674 PCT Pub. Date Feb. 13, 1997An apparatus for winding round the stem of a button is disclosed wherein the drawbacks of the prior invention disclosed in U.S. Pat. No. 5,082,151 were settled. Namely, after drawing the winding thread from the bobbin and in the process of the winding operation, if the thread is recoiled and drawn, the tensile force of the thread decreases and during the winding operation maintaining high rotation speed, the thread is frequently cut off, which leads to the frequent interruption of the winding operation. It was very inefficient in the respect of operation and had impractical disadvantage. Such apparatus according to the present invention comprises a bobbin supporting means for interchangeably supporting the bobbin supplying the winding thread so as to rotate on its own axis to the unloosening direction of the thread in accordance with winding and drawing force of the thread, a thread winding means being fixedly mounted on the equal rotation axis to said bobbin supporting means for receiving from the bobbin the winding thread and winding it round the stem of the button while being rotated along with the bobbin in the equal direction and at the equal angular velocity, and a winding rotation means for rotatively mounting on the support the bobbin supporting means and the thread winding means being fixedly mounted on equal rotation axis and rotating it with driving force of a motor.
