摘要： The present disclosure is concerned with a method of making a brush having the steps of: providing a plurality of first filaments, each first filament having a first end and a second end; bringing the plurality of first filaments into a first pre-determined shape such that the first ends of the first filaments are arranged side by side on a common contour; fixedly connecting the first ends of the plurality of first filaments so that a first pre-tuft having the first predetermined shape and a connected first end is formed; bringing at least a second tuft element having a first end and a second end together with the first pre-tuft into a second pre-determined 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 pre-determined shape and a connected end is formed; and attaching the final tuft to a brush body, in particular by overmolding the connected end of the final tuft with a plastic material, thereby forming at least a portion of the brush body.

摘要： A head for an oral care implement comprises a mounting surface and at least one twisted tuft comprising a plurality of filaments and having a base mounted on the mounting surface. The twisted tuft has an outer lateral surface, a longitudinal axis, a lower cross-sectional area extending in a plane that is perpendicular to the longitudinal axis and that is arranged at the base, and an upper cross-sectional area extending in a plane that is perpendicular to the longitudinal axis and that is arranged at the free end of the twisted tuft. The lower cross-sectional area and the upper cross-sectional area have substantially the same shape and size. At least the filaments forming the outer lateral surface are each substantially straight and are all inclined with respect to the longitudinal axis in either a clockwise direction or in a counterclockwise direction. The upper cross-sectional area is twisted with respect to the lower cross-sectional area by a twisting angle α and the upper cross-sectional area is not congruent with the lower cross-sectional area when they are orthogonally projected onto each other along the longitudinal axis.
