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.
