  • Bristle cluster stuffing tool ram and method of use
    Patent number: 8052222
    Abstract: A bristle cluster stuffing tool ram is used for pressing a strip-shaped holding element, preferably an anchor, into a borehole that is arranged in a brush head and serves for accommodating a bristle cluster. The end face of the ram comprises a pressing surface for pressing in the holding element. The pressing surface is defined by longitudinal sides and face sides. The rain has end face regions that penetrate into the material of the brush head when the holding element is pressed in. The cross section of the ram that lies outside the end face regions and penetrates into the borehole is wider than the end face regions.
