Abstract

A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener. The tufting tool includes a notch. The method provides a brushroll with bristles tufted into the bristle hole adjacent the bristle stiffener. A brushroll for a vacuum cleaner can be made using an injection molding process, with bristle stiffeners integrally molded with the dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

Claims

1. A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener, comprising:

positioning the tufting tool relative to the brushroll dowel to at least partially receive the bristle stiffener within a notch on the tufting tool;

inserting bristles into the tufting tool;

guiding the bristles from the tufting tool into the bristle hole; and

fastening the bristles in the bristle hole.

2. The method according to claim 1, wherein guiding the bristles from the tufting tool into the bristle hole comprises guiding the bristles through a sleeve of the tufting tool having an inlet opening and an outlet opening, wherein the outlet opening is adjacent the notch.

3. The method according to claim 2, wherein positioning the tufting tool relative to the brushroll dowel to at least partially receive the bristle stiffener partially forms the outlet opening of the sleeve.

4. The method according to claim 2, wherein the outlet opening is in communication with the notch.

5. The method according to claim 1, wherein guiding the bristles from the tufting tool into the bristle hole further comprises at least partially guiding the bristles into the bristle hole with a portion of the bristle stiffener exposed by the notch.

6. The method according to claim 1, wherein inserting the bristles into the tufting tool comprises pressing the bristles into the bristle hole.

7. The method according to claim 6, wherein pressing the bristles into the bristle hole comprises bending a plurality of bristles to form a bend which is received into the bristle hole which is guided from the tufting tool into the bristle hole.

8. The method according to claim 1, wherein fastening the bristles in the bristle hole comprises stapling the bristles in the bristle hole.

9. A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener, wherein the bristle stiffener projects beyond one side of the bristle hole in a radial direction from the dowel, the method comprising:

positioning the tufting tool comprising a notch relative to the brushroll dowel to at least partially receive the bristle stiffener within the notch on the tufting tool;

inserting bristles into the tufting tool;

guiding the bristles from the tufting tool into the bristle hole; and

fastening the bristles in the bristle hole.

10. The method according to claim 9, wherein guiding the bristles from the tufting tool into the bristle hole comprises guiding the bristles through a sleeve of the tufting tool having an inlet opening and an outlet opening, wherein the outlet opening is adjacent the notch.

11. The method according to claim 10, wherein positioning the tufting tool relative to the brushroll dowel to at least partially receive the bristle stiffener partially forms the outlet opening of the sleeve.

12. The method according to claim 10, wherein the outlet opening is in communication with the notch.

13. The method according to claim 9, wherein guiding the bristles from the tufting tool into the bristle hole further comprises at least partially guiding the bristles into the bristle hole with a portion of the bristle stiffener exposed by the notch.

14. The method according to claim 9, wherein inserting the bristles into the tufting tool comprises pressing the bristles into the bristle hole.

15. The method according to claim 14, wherein pressing the bristles into the bristle hole comprises bending a plurality of bristles to form a bend which is received into the bristle hole which is guided from the tufting tool into the bristle hole.

16. The method according to claim 9, wherein fastening the bristles in the bristle hole comprises stapling the bristles in the bristle hole.
