Abstract
A bristle structure including at least two stem wires spirally wound together to form a longitudinally extending core of the bristle structure and a plurality of bristles extending outwardly from the longitudinally extending core. Each of the bristles has a first end and an opposed second end, and each of the bristles is clamped between the stem wires such that the second end of each bristle extends a greater distance from the longitudinally extending core than the first end of the each bristle.
Claims22
A bristle structure comprising:
- at least two stem wires spirally wound together to form a longitudinally extending core of said bristle structure;
- and
- a plurality of bristles extending outwardly from said longitudinally extending core, each of said bristles having a first end and an opposed second end and being clamped between said stem wires such that said second end of each bristle extends a greater distance from said longitudinally extending core than said first end of said each bristle.
A bristle brush comprising:
- at least two stem wires spirally wound together to form a longitudinally extending core having a first end and an opposed second end;
- first and second support arms respectively extending from said first and second ends of said longitudinally extending core;
- a plurality of bristles extending outward from said longitudinally extending core, each of said bristles having a first end and an opposed second end, and being clamped between said stem wires such that said second end of each bristle extends a greater distance from said longitudinally extending core than said first end of said each bristle;
- and
- a handle coupled to at least one of said first and second support arms.
2 more elements
A method of manufacturing a bristle structure, comprising the steps of:
- positioning a plurality of bristles between at least two stem wires such that a first end of each bristle extends outward from the stem wires a first distance and a second end of each bristle extends outward from the stem wires a second distance greater than the first distance;
- and
- spirally winding the stem wires together to form a longitudinally extending core of the bristle structure and to clamp the bristles between the stem wires, whereby the first ends of the bristles collectively form a first helical pattern extending along the longitudinally extending core, and the second ends of the bristles collectively form a second helical pattern extending along the longitudinally extending core.
