  • Method for producing toothbrushes covered with bristles in an anchor-free manner
    Patent number: 9173480
    Abstract: The tips of pointed bristles are mechanically processed in order to remove any corroded threads or residual threads from the tip. Mechanically processed pointed bristles are fed to a receptacle recess of a tool in bundles, and aligned by means of a pin guided in the receptacle recess. The pointed bristles are pushed through the passage of the bristle carrier plate, and the end section are subsequently melted by means of a heating die in order to attach the pointed bristles to the bristle carrier plate. The mechanical processing of the tips of the bristles enables an error-free further processing of the pointed bristles utilizing the bristling method, particularly the AFT method.
