ABSTRACT:
The ferrule of a bristle brush includes an annular bead peripherally about the ferrule proximate one end thereof, and the bead has a sufficiently large cross-sectional profile and circumscribes a volume having a sufficiently large cross-sectional area relative to the cross-sectional area of the volume circumscribed by the major tubular extent of the ferrule in order to permit expansion of that part of the bristle hold located in the volume circumscribed by the bead. A hardenable liquid adhesive material poured into the ferrule after the bristle is positioned therein will permeate appreciably into the hold of the bristle thereby substantially to encapsulate the same and to secure the filaments thereof tenaciously to the ferrule.
