[origin: WO2023285196A1] A method for anchorless fastening of at least one bristle in an assigned opening (12), in the form of a blind hole, in a bristle carrier made of plastic as part of a subsequent brush, which has a front side (18) from which the opening (12) into the bristle carrier (10) extends, wherein the at least one bristle has a thickened fastening end (24). After inserting the at least one bristle in the opening (12) from the front side (18) of the bristle carrier (10), wherein an impact pulse is exerted on part of the circumference or the whole circumference of the front rim (22) of the opening (12), the rim is plastically deformed.
