Musical instrument string modifying device2009-10-24 00:00:00it 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.ClaimsInvention is claimed as follows:
1. An apparatus for modifying a musical instrument string having a core and a cover wire of circular cross-section helically wound on said core, said apparatuscomprising a frame, a first roller rotatably mounted on an axis fixed with respect to said frame, and a second roller rotatably mounted on an axis moveable with respect to said first roller, guide means for maintaining said string in proper position topass between said rollers while said string rotates about its axis and additionally moves axially through said rollers, and power means for applying force to urge said second roller against said first roller, thereby compressing said string andflattening the crown of said cover wire on the outer surface of said string while maintaining substantially the original curvature of said cover wire in the remainder of said c...
