  • Patent number: 6665902
    Abstract: A strip brush assembly for sweeping devices or machines comprises a plurality of metallic wires with attachment ends thereof being secured to a polymeric hub. The hub, while retaining the wire ends together is bonded or attached to a polymeric base that is configured with a channel to receive the hub. The base also has members shaped to secure the base to a brush assembly holder. An apparatus for making the brush assembly includes an extruder/shaping device that takes lengths of wires and continuously extrudes and shapes the hub around ends of the wires. The hub is then continuously attached to a polymeric base using fusion, adhesives, a combination of the two, or the like. The hub-containing base can then be cut to length as a metallic wire strip brush assembly for use on a mandrel.
