[0002] Strings are important parts of stringed vibrating instruments and play a decisive role in the sound quality of the instrument. When producing strings, it is generally necessary to tension and fix the two ends of the main string to form a certain axial pre-tension, and then wrap the wire around the outside of the main string along the length direction. Depending on the needs, the wire may need to be formed by multiple winding processes of different types of silk threads. When winding, the two end fixings of the main string are rotated to make it rotate at a certain speed, and then the wire is wound around the outside of the main string.
[0003] The existing string machines generally tighten the wire manually and then wind the wire around the main string through the rotation of the main string. The tension of the wire cannot be guaranteed by tightening the wire manually, so that the tightness of the wire winding is uneven, affecting the quality of the sound of the string.
