  • Patent number: 11707129
    Abstract: A strip brush assembly with a plurality of elongated polymer bristles forming a section and a plurality of elongated metal bristles forming another section adjacent the polymer bristles section, such that the metal bristles section is supported by the polymer bristles section. The polymer and metal bristles are bonded and encapsulated in a base formed by direct extrusion onto and around the polymer and metal bristles to secure them to the formed base. The strip brush assembly may be used on a tubular mandrel of a street sweeper.

  • Publication number: 20130305473
    Abstract: A system and method that utilizes modular components to form a customizable brush for different applications with ease and at a low cost. The system and method utilizes three main components: a base, a plurality of rails, and a plurality of strip brush elements. The plurality of rails is fastened to the base and the plurality of rails holds the strip brush elements to the base to form a brush. All three components may be made of a thermoplastic or thermoset, non-metallic material which can be either rigid or flexible to allow the resulting brush to be easily recyclable.
