A head for an oral care implement comprises at least one tooth cleaning element of a first type and at least one tooth cleaning element of a second type. The at least one tooth cleaning element of the first type has a length extension along a longitudinal axis being about 1 mm to about 2 mm longer than the length extension of the at least one tooth cleaning element of the second type along its longitudinal axis. The at least one tooth cleaning element of the first type is a tuft of a first type comprising a plurality of filaments. Each filament has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, the projections and channels being arranged in an alternating manner. The at least one tuft of the first type has a packing factor within a range from about 40% to about 55%, preferably from about 45% to about 50%.

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.

An apparatus for producing bristle products is provided. The apparatus (1) has at least two, preferably redundant, tufting units (3, 4) which can optionally be moved from a setting-up position (7) outside a working chamber (8) of the apparatus (1) into a working position (9) within the working chamber (8) and vice versa, in particular such that, whenever one of the at least two tufting units (3, 4) is arranged in the setting-up position (7), another of the at least two tufting units (3, 4) can be or is arranged in the working position (9).

An oral care implement having a head with a bristle bearing surface. The oral care implement may include a central bristle tuft extending from a central portion of the bristle bearing surface, the central bristle tuft terminating in a domed distal surface. Furthermore, the oral care implement may include a plurality of perimetric bristle tufts extending from the bristle bearing surface and arranged to circumferentially surround the central bristle tuft. Each of the perimetric bristle tufts may have an inclined distal surface that slopes downward towards the central bristle tuft. The bristle bearing surface of the head may have a total surface area (TSA), and the toothbrush may include a tooth cleaning element field having X number of tooth cleaning elements that collectively occupy a total cleaning element area (TCEA) such that

[00001]$\frac{1}{X}\times \frac{TCEA}{TSA}=Z$

and Z is in a range of 0.04 to 0.065.

Disclosed are a makeup brush and a manufacturing method thereof. The makeup brush includes a brush head and a brush handle. A bristle sheet is tightly bonded to an outer root of the brush head, and a height of the bristle sheet is less than that of the edge of the brush head. Therefore, in the process of makeup, the layering of bristles of the brush head and the outer bristle sheet is enhanced to make the brush more stylish, contributing to a more delicate makeup effect and an increased skin touching feeling.

An apparatus (1) for forming bristle bundles (2) is provided. The apparatus (1) includes at least one bundle pocket (3), intended to receive a bristle bundle (2) to be formed. The bundle pocket (3) has at least one piercing (6) in the side. A displacement device (7) on the apparatus (1) can be introduced into the bundle pocket (3) through this piercing (6) to create a clearance (29) inside a bristle bundle (2) to be formed. The bundle pocket (3) and the bristle bundle (2) located therein are heated by the heating device (4) in the apparatus (1) to fix the shape of the bristle bundle (2) defined by the bundle pocket (3) and the displacement device (7).
