A head for an oral care implement has a mounting surface comprising at least one tuft of a first length and at least one tuft of a second length, the first length being longer than the second length measured from the mounting surface of the head along a longitudinal axis of the tufts. The at least one tuft of the first length comprises filaments having a substantially circular cross-sectional area extending in a plane perpendicular to the longitudinal axis and an end-rounded free end, while the at least one tuft of the second length comprises flagged filaments having split free ends.

A head (14) for an oral care implement (10) has a mounting surface (20) comprising at least one tuft of a first type (16) and at least one tuft of a second type (18), the at least one tuft of the first type (16) and the at least one tuft of the second type (18) each having a cross-sectional area extending in a plane substantially perpendicular to a longitudinal axis. The cross-sectional area of the tuft of the first type (16) is smaller than the cross-sectional area of the tuft of the second type. The at least one tuft of the first type (16) comprises filaments having a substantially circular cross-sectional area extending in a plane perpendicular to the longitudinal axis and having an end-rounded free end, and the at least one tuft of the second type (18) comprises flagged filaments having split free ends.

A method of forming a bristle field for an oral care implement. The method includes providing a bundle of bristles and aligning the bundle of bristles with an insertion opening in a guide member. Upon insertion into the guide member, the guide member divides the bundle of bristles into a plurality of bristle tufts. The guide member can be aligned with tuft holes on a head or head plate of an oral care implement so that the bundle of bristles can be inserted through the guide member and into the tuft holes. As a result, a single bundle of bristles can be used to mount a plurality of bristle tufts to the head or head plate.

According to a method or an apparatus for fastening bristles in a bristle carrier (10) without using an anchor a heating (39) is provided in a tool part configured to transport the bristles. After inserting the bristles into anchoring openings (12) in the bristle carrier (10), the anchoring openings are closed by applying pressure.

A toothbrush includes a handle and a bristle-carrying head part, which are connected to each other by a neck part, the head part having a multiplicity of tufts of bristles consisting of bristles. An anchor is oriented at right angles to the longitudinal axis. Two or more tufts of bristles have a bristle tuft half with bristle ends standing up higher in relation to the bristle ends of the other bristle tuft half.

A feeding device for feeding batches of bristle filaments to a bristle filament cassette includes a vertical magazine and at least one batch of bristle filaments arranged therein. In order to prevent individual bristle filaments from being pressed out of the batch of bristle filaments and to provide an ecologically optimized device, the batch of bristle filaments is held in a reusable and circumferentially enclosed batch carrier. A tufting device with the feeding device of a bristle filament cassette and a transfer device between the bristle filament cassette and the feeding device are provided. A corresponding method for fitting a brush is also provided.
