Abstract In a method for connecting bristles to a bristle carrier, each of which is made of thermoplastic material, at least the ends of the bristles are heated so that a reversal of the molecules from an oriented stretched form to a non-oriented balled form takes place and thereby forms a thickening on the bristle ends, upon which the bristles with their thickened ends are inserted into the melted bristle carrier until the melt of the carrier flows behind the thickened end whereby after hardening of the melt an interlocking shape connection is obtained between the bristles and the bristle carrier which joint may also include, in the case of corresponding work material pairs, a material bonding, the interlocking shape connection being independent of the type of materials used for the two parts.
