Patent ID: 8052222

Claim:
A method of manufacturing a brush, the method comprising providing a brush head defining bristle cluster boreholes; providing a stuffing tool ram with opposed broad longitudinal sides and a pressing surface that includes a central region and two end regions, the central region having a width as measured between the broad longitudinal sides greater than a width of the end regions, a first broad longitudinal side of the ram disposed between ends of face sides of the ram and a second broad longitudinal side of the ram opposite the first broad longitudinal side, wherein the second broad longitudinal side is shorter than the first broad longitudinal side; and with the ram, pressing strip-shaped holding elements into engagement with corresponding bristle clusters and into corresponding boreholes with the end regions of the ram pressing surface penetrating into the material of the brush head as the central region extends into the borehole, thereby anchoring the bristle cluster in the borehole.
