ABSTRACT:
A modified musical instrument string comprising a core having a fine cover wire helically wound thereon, said cover wire having a substantially round cross-section over the major proportion of its surface, but having compressed flats at the crown of said wire at the outer surface of said string but not at the inner surface of said cover wire. Said modification is effected by 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 between guides, the crown or outer arcuate surface of the helical winding at the outer surface of the string is flattened by passing the string while it is rotating between rollers biased toward each other, 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. The method for modifying such a wound musical instrument string is also disclosed.
