A brush head (10) and a method for manufacturing a welded tuft assembly (20) for a brush head (10). The method includes inserting a bristle tuft (21) into an opening (51) in a retention element (52). A proximal end of the bristle tuft (23) and a proximal side (53) of the retention element are laser welded to at least partially melt the bristle tuft and at least a portion of the proximal side of the retention element together to create a merged proximal end head portion (26) that holds the welded tuft assembly together.

A method for wire bristle tuft attachment. The method includes clamping a brush head of a grill brush using a fixture, arranging a plurality of bristles to form a bristle grouping using a terminal, inserting the plurality of bristles in a recess in the brush head, and forming an irregular bend in the terminal by pressing the terminal into the recess by a press machine.

A brush head (10) and a method (200) for manufacturing a brush head. The method (200) includes stamping (220) a plurality of openings (62) into a strip or roll of backing material (60). A bristle tuft (21) is inserted into each of the openings in the backing material. A proximal end (23) of each bristle tuft is bonded to a proximal side (63) of the backing material to create a merged proximal end head portion (26). Excess portions of the backing material are removed to form a plurality of carrier elements (24) about the openings from the backing material. The carrier elements form a plurality of merged tuft assemblies (20). A platen (42) of a neck (40) is positioned in relation to the merged tuft assemblies. A matrix material (30) is injected around the platen and the merged tuft assemblies to at least partially encompass the platen and the carrier elements of the merged tuft assemblies.

A method for manufacturing a toothbrush having a bristle carrier made of a thermoplastic material with a front side and a rear side is provided. At least one recess formed as a blind hole in the bristle carrier extends from the front side in the bristle carrier, and holds at least one bristle. The at least one bristle is received in a receiving opening of a tool melted to form a thickening at its attachment-side end and inserted with its attachment-side end into the recess. The thermoplastic material is heated and, by pressing the tool against the front side of the bristle carrier, is deformed such that the thermoplastic material is displaced radially inwards into the recess, at least in the region of an edge surrounding the recess, for the form-fitting sealing of the thickening, in that a projection provided radially adjacent to the recess is pressed into the thermoplastic material.

A brush product, in particular a toothbrush, having a base body with a head part with a front and a rear side, which includes a bristle carrier with a longitudinal axis and a transverse axis and a bristle field protruding therefrom, wherein the bristle field is formed by at least one group of cleaning elements; a handle part; and a neck part connecting the head part and the handle part; wherein the bristle carrier is provided with bristles which are mounted without being anchored and wherein the bristle carrier includes substantially a central support area, an upper support area, a lower support area, a right support area and a left support area, in which the groups of cleaning elements are arranged. Also, a corresponding method and tool.

A method and device for the production of bristle fields for brushes is provided. The method for producing bristle fields includes filling bundle holders (3) of a bristle field support plate (2) with bundles of bristles using at least two different funnel plates (4, 5). The device includes at least two different funnel plates with complementary hole patterns in relation to a complete hole pattern (13) formed by inlet openings (12) of the bundle holders (3) on the bristle field support plate.
