Apparatus for manufcturing guitar string

An apparatus for manufacturing a guitar string, the apparatus comprising:

• a table part;
• a holding part which is installed on the table part and holds both ends of a first wire so that the first wire is rotatable;
• a winding part which is movable in a direction in which the first wire is extended, so that the winding part sequentially winds a second wire around on the outer surface of the first wire being rotated;
• and
• a supply part for supplying the second wire to the winding part,
• wherein the supply part includes:
• a height measuring part;
• a first pulley part including a movable pulley around which at least a portion of the second wire is wound, and a movable body provided with a hole through which the height measuring part passes, and coupled with the movable pulley, wherein the movable body moves along a direction in which the height measuring part extends when the second wire starts to be wound around the first wire;
• a bobbin part around which the second wire has been wound, the bobbin part supplying the second wire to the movable pulley;
• a motor part for rotating the bobbin part;
• and
• a control part which controls the speed of the second wire supplied to the winding part by controlling the operation of the motor part, and which causes the motor part to rotate the bobbin part at a speed corresponding to height information of the movable body measured by the height measuring part,
• wherein the height measuring part senses at least any one of the height and displacement of the movable body, and is formed in a bar shape having magnetism,
• wherein the movable body is located at a first height before the second wire starts to be wound around the first wire, and is moved to a second height higher than the first height when the second wire starts to be wound around the first wire by the movement of the winding part, and
• wherein the smaller the width of the second wire is, the lower the second height is set.
