Abstract

A method of making a brush includes providing a plurality of first filaments, each having a first end and a second end; bringing the plurality of first filaments into a first predetermined shape such that the first ends are arranged side by side on a common contour; fixedly connecting the first ends so that a first pre-tuft having the first predetermined shape and a connected first end is formed; bringing a second tuft element having a first end and a second end together with the first pre-tuft into a second predetermined shape such that the first end of the second tuft element and the connected first end of the first pre-tuft are arranged side by side on a common contour; fixedly connecting the connected first end of the first pre-tuft and the first end of the at least second tuft element so that a final tuft having the second predetermined shape and a connected end is formed; and attaching the final tuft to a brush body by overmolding the final tuft's connected end with a plastic material.
