ABSTRACT:
Apparatus for modifying a musical instrument string as it is being fabricated by winding a fine metal wire helically about a core, the apparatus comprising a first roller having a fixed axis and a second roller mounted on a moveable arm for moving the second roller toward and away from the first roller, and a controllable air cylinder apparatus connected to said moveable arm for moving the second roller toward the first roller. As the string being wound and rotating passes between the two rollers and is maintained between guides, the crown or outer arcuate surface of each helical winding is flattened at the outer surface of the string, resulting in a string which produces less noise when the player slides his fingers along the string to change positions, and which still provides perfect intonation and frequency response.
