Abstract
A musical instrument string with hyper elliptical wound cover wire includes a wound musical string assembly (10) having a center string (12) and a shaped cover wire (24) wrapped in a spiral winding pattern (18). The shaped cover wire (24) is shaped to have a wire height (30) which is greater than a wire width (32) and is wound such that the wire height (30) is aligned perpendicularly to the longitudinal axis (14) of the center string (12) while the wire sides (26) abut tightly against those of adjacent iterations (20). The shaped cover wire (24) is shaped during the winding process by passing between pinch rollers (38) while under extrusion pressure.
Claims16
A wound musical instrument string, comprising:
- a center string;
- and
- a cover wire wound in a spiral winding pattern about said center string, wherein
- said cover wire is shaped to have a cross section with generally flat opposing sides and rounded opposing ends and with a wire height which is greater than a wire width;
- and
- said cover wire is arrayed within said spiral winding pattern such that said wire height is arrayed generally perpendicularly to said center string.
In a wound string for musical instruments formed by a center string and a cover wire forming a spiral winding pattern about the center string, the improvement comprising:
- pre-shaping said cover wire to have a hyper elliptical cross sectional shape with flattened opposing sides and rounded opposing ends and with a wire height which is greater than a wire width;
- and
- orienting said cover wire within said spiral winding pattern such that said wire height is arrayed generally perpendicularly to said center string.
A method for forming a wound string for musical instruments, in steps comprising:
- stretching a center string on a rotating mechanism to rotate said center string about a longitudinal axis;
- passing a round wire between an opposed pair of pinch rollers so as to form a shaped cover wire characterized by having a generally hyper elliptical shape with flatter opposing sides and rounder opposing ends and having a greater end to end cross-sectional dimension than a side to side cross-sectional dimension;
- and
- attaching said shaped cover wire to said center string and winding said cover wire about said center string in a spiral winding pattern wherein said shaped cover wire is maintained in an orientation where said ends are arrayed perpendicularly to said center string throughout said spiral winding pattern.
