Abstract

A method for manufacturing products with bristles, composed of a bristle holder made of pourable or foamable material and plastic bristles anchored therein. The bristles are introduced through channels into a mold for the bristle holder, melted by heat at the end in the mold to form a thickening, and the thickening of each bristle is brought into a sealing fit with the opening of the channel guiding it, possibly leaving an undercut at the thickening, and the mold is then filled with bristle holder material. The bristles and bristle holders can be made from different materials by casting or foaming of the bristle holder, whereby the channels guiding the bristles are sealed off by the thickening so that the bristle holder material cannot escape to the outside and especially cannot have a disadvantageous effect on the bristle shoulder. In addition, a combined force and force-fitted anchoring of the bristles in the bristle holder is ensured.
