Bristle articles, which comprise a bristle carrier and thermoplastic bristles anchored therein are produced in that holes for receiving the bristles are formed on the bristle carrier, the fixing side ends of the bristles are melted, accompanied by a reduction of their length and the formation of a thickened portion and inserted with the thickened portion first into the holes on the bristle carrier. In order to be able to joint bristles from random thermoplastics with a bristle carrier made from a random material in a short time, the holes in the bristle carrier are formed with an at least zonally smaller free cross-section than that of the thickened portions on the bristle ends and that the thickened portions and/or the wall of the holes are heated to a joining temperature between the transition temperature and the flow temperature in the case of amorphous thermoplastics and to a temperature between the latter and the crystalline melting temperature with partly crystalline thermoplastics and are kept at this joining temperature, at which the thermoplastics are in the entropy elastic state and in this state the thickened portions are inserted in the holes by thermoforming.
