Реферат: In the proposed method of molding toothbrushed, a mold with relatively movable mold parts (14,16)defining at least one molding cavity (20 corresponding in shape to a toothbrush body is used. One of the mold parts (16)has a brush head defining cavity portion with a plurality of holes (24)for partial penetration into the cavity portion of a like number of fibre tufts. Plasticized molding material is injected under pressure into the cavity (20). Pressure within the cavity is sensed during the injecting step. The injection is topped when the pressure within the cavity exceeds a predetermined pressure value, thereby avoiding any leakage of molding material through the holes (24).
