    摘要： 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.
