  • Publication number: 20240023701
    Abstract: The present invention concerns a process for producing toothbrushes covered with bristles in an anchor-free manner, in which a tuft of bristles with cylindrical bristles and/or pointed bristles is introduced into a receiving recess of a mold of a bristle-providing machine and, by means of a profiled pin guided in the receiving recess, force is applied to the end facing the pin of the bristles of the tuft of bristles for the alignment thereof, so that the bristles of the tuft of bristles are aligned by means of an end face of the profiled pin and, as a result, form the topography that complements the topography of the end face of the profiled pin, wherein the profiled pin has on the end face that acts on the bristles a discontinuous surface, which forms multiple levels. This achieves a bristle area configuration that has multiple areas of use. A correspondingly produced toothbrush is also described.
