Method for tufting bristles and brush using the same
View Patent ↗A hair brush may include a body having a receiving portion at a first end. A cushion pad having an inner surface and an outer surface may be disposed in the receiving portion, and may include a plurality of bristle anchors having an aperture. A plurality of bristles may be tufted into each of the apertures.
1. A method of bristle and cushion pad fabrication, comprising:
molding a plurality of substantially spherical bristle anchors from a first material;
forming a first aperture in each of the substantially spherical bristle anchors;
molding a cushion pad having a plurality of second apertures, an inner surface, and an outer surface, wherein the cushion pad is constructed from a second material;
securing the substantially spherical bristle anchors in the plurality of second apertures; and
tufting a plurality of bristles in the first apertures.
2. The method of claim 1 , wherein molding a plurality of substantially spherical bristle anchors includes molding a first portion and a second portion of the plurality of substantially spherical bristle anchors.
3. The method of claim 2 , further including providing a groove on the substantially spherical bristle anchors between the first and second portions of the substantially spherical bristle anchors.
4. The method of claim 3 , wherein the grooves are provided by molding the substantially spherical bristle anchors.
5. The method of claim 3 , wherein the grooves are provided by machining the substantially spherical bristle anchors.
6. The method of claim 1 , wherein the first apertures are provided by molding the substantially spherical bristle anchors.
7. The method of claim 1 , wherein the first apertures are provided by drilling the substantially spherical bristle anchors.
8. The method of claim 1 , further including adhering the bristles into the first apertures with adhesive.
9. The method of claim 1 , further including forcing the plurality of bristles into the first apertures.
10. The method of claim 1 , further including engaging the substantially spherical bristle anchors and the cushion pad.
11. The method of claim 10 , wherein engaging the substantially spherical bristle anchors and the cushion pad further includes snapping the substantially spherical bristle anchors into the cushion pad.
12. The method of claim 1 , wherein the step of molding the plurality of substantially spherical bristle anchors and the step of molding the cushion pad includes integrally molding the substantially spherical bristle anchors and the cushion pad together.
13. The method of claim 12 , wherein the first material and the second material are different and selected for producing a covalent bond between the substantially spherical bristle anchors and the cushion pad when integrally molded together.
14. The method of claim 12 , wherein the step of integrally molding the substantially spherical bristle anchors and the cushion pad together includes pre-forming the substantially spherical bristle anchors and molding the cushion pad around the pre-formed substantially spherical bristle anchors so that the substantially spherical bristle anchors are embedded securely in the cushion pad.
15. The method of claim 12 , further comprising:
providing a body defining a rear cavity and a front face defining apertures; and
positioning the cushion pad in the cavity with the substantially spherical bristle anchor apertures aligned with the front face apertures,
wherein the step of tufting the bristles is performed after the cushion pad is positioned in the cavity and is performed so that the bristles extend from the substantially spherical bristle anchors and through the front face apertures and beyond.
16. The method of claim 12 , wherein the first material that the substantially spherical bristle anchors are constructed from is a propylene material.
17. The method of claim 12 , wherein the second material that the cushion pad is constructed from is a thermoplastic elastomeric material.
18. A bristle and cushion pad assembly fabricated by the method of claim 1 .
19. A method of fabricating a hairbrush, comprising:
firstly molding a plurality of bristle anchors from a first material, wherein the bristle anchors each include a first end with a bristle aperture, a second end opposite the first end, and a groove between the first end and the second end; and
secondly molding a cushion pad from a second material,
wherein the cushion pad is integrally molded around the bristle anchors and into the grooves so that the bristle anchors are embedded securely in the cushion pad, wherein the first material and the second material are different and selected for producing a covalent bond between the bristle anchors and the cushion pad.
20. The method of claim 19 , further comprising:
forming an aperture in each of the bristle anchors;
providing a body defining a rear cavity, a front face, and apertures through the front face;
positioning the cushion pad in the cavity with the bristle anchor apertures aligned with the front face apertures; and
tufting the bristles so that they extend from the bristle anchors and through the front face apertures and beyond.
21. The method of claim 19 , wherein the groove extends around an entire perimeter of the bristle anchor.
22. The method of claim 19 , wherein the first material is a propylene material and the second material is thermoplastic elastomeric.
