Problems solved by technology

[0008] However, in the conventional single-needle automatic embroidery machine, when the thread connected to the needle working unit needs to be cut during the embroidery work, the ends of the cut thread are scattered, so the thread is not easy to be sewn into the needle.
Therefore, workers need to completely cut off the ends of the loose threads, thereby reducing work efficiency
In addition, in order to move the cut thread to the needle work unit, workers must manually place the cut thread at the ready position of the thread supply unit, thereby reducing work efficiency
