摘要：
A method of manufacturing a brush includes providing a core wire section having a proximal end and a distal end, and an integral tip on the distal end, forming a bristle element having a throughbore, and inserting the core wire section into the throughbore until the bristle element is received on the core wire section.
技术问题语段：
The technical problem addressed in this patent is the need for a brush that combines the benefits of twisted wire brushes and stacked disc brushes, allowing for a wider array of shapes and configurations and easy customization. The invention provides a brush with a core section having a proximal end and a distal end, and an integral tip formed on the distal end, as well as at least one bristle element slidably received on the core section. The brush can also be shaped, trimmed, or deformed like traditional fiber brushes.
技术功效语段：
The present invention relates to a brush with a twisted wire core and a method of manufacturing it. The technical effects of this invention include the ability to create a brush with a wider range of shapes and configurations than currently exist in the art, and the ability to consistently form brushes with bristle characteristics that vary at regular or irregular intervals along the length of the brush. The brush also includes a plurality of discs that interact with the twisted wire core to inhibit rotation of the discs relative to the core, and can be shaped, trimmed, or deformed like traditional fiber brushes.
权利要求：
WHAT IS CLAIMED IS:
1. A brush, comprising:
a core section having a proximal end and a distal end, and an integral tip formed on the distal end; and
at least one bristle element slidably received on the core section.
2. The brush of claim 1, wherein:
the integral tip forms a position stop preventing the at least one bristle element from sliding off the distal end of the core section.
3. The brush of claim 2, wherein:
the core section includes at least two leg members twisted about one another in a helical configuration.
4. The brush of claim 3, wherein:
the integral tip is generally spherical in shape.
5. The brush of claim 4, wherein:
the integral tip has a diameter that is greater than a diameter of the core section.
6. The brush of claim 5, wherein:
the integral tip and the core section are homogeneous.
7. The brush of claim 1, wherein:
the core section is formed form a metal or metal alloy.
8. The brush of claim 1, wherein:
the at least one bristle elements is a plurality of discs defining a brush head.
9. The brush of claim 8, wherein:
the core section includes a plurality of leg portions twisted in a helical configuration, and a plurality of fiber bristles anchored between the plurality of leg portions;
wherein the plurality of discs are received about the plurality of fiber bristles such that the plurality of fiber bristles inhibit rotational and axial movement of the plurality of fiber bristles with respect to the core section.
10. The brush of claim 9, wherein:
the brush head is shaped by at least one of bending a portion of the core section and / or trimming the plurality of discs.
11. The brush of claim 1, wherein:
the at least one bristle element is an additively manufactured or molded bristle element having a plurality of bristles.
12. The brush of claim 8, wherein:
the bristle block is shaped by bending a portion of the core section.
13. A method of manufacturing a brush, comprising the steps of:
providing a core section having a proximal end and a distal end, and an integral tip on the distal end; and
positioning at least one bristle element on the core section, the at least one bristle element having a throughbore through which the core section extends;
wherein the integral tip forms a position stop preventing the at least one bristle element from sliding off the distal end of the core section.
14. The method according to claim 13, wherein:
the at least one bristle element is additively manufactured or molded.
15. The method according to claim 13, wherein:
the core section includes a plurality of leg portions twisted in a helical
configuration;
wherein the at least one bristle element is a plurality of disc elements.
16. The method according to claim 15, wherein:
the core section includes a plurality of bristles anchored between the plurality of leg portions;
wherein the plurality of bristles inhibit axial and rotational movement of the plurality of disc elements on the core section.
17. The method according to claim 13, further comprising the step of:
imparting a bend or curve to the core section after positioning the at least one bristle element on the core section.
18. The method according to claim 13, further comprising the step of:
trimming the at least one bristle element after positioning the at least one bristle element on the core section.
19. A brush, comprising:
a core section having a plurality of leg portions twisted in a helical configuration, and a plurality of fiber bristles anchored between the plurality of leg portions; and
a plurality of disc elements received on the core section;
wherein the plurality of fiber bristles are configured such that the plurality of fiber bristles interact with the plurality of disc elements to inhibit rotation of the plurality of disc elements relative to the core section.
20. The brush of claim 19, further comprising:
an integral tip formed on a distal end the core section, the integral tip having a diameter that is greater than a diameter of an aperture of each of the plurality of disc elements through which the core section is received, such that the integral tip forms a position stop preventing the plurality of disc elements from sliding off the distal end of the core section.
