Abstract
A method for the production of bristles structures on an arbitrary kind of carrier using a mold tool is described having channels extending from channel walls for shaping bristles, wherein a mold mass for forming the bristles is introduced under pressure into the channels, preferentially using the injection molding technique. Towards this end, the carrier is disposed directly or indirectly onto the mold walls of the channels in such a fashion that the free cross-section of the channels is completely covered and the mold mass is subsequently introduced onto the carrier with a sufficient mold pressure (injection pressure) that the carrier is broken-through in the vicinity of the free cross-section of the channels thereby displacing the carrier material, with the carrier mass subsequently filling the channels.
