Abstract

A bristle sub-assembly includes first and second base strings and a plurality of polymeric monofilaments connected to and extending between the first and second base strings. The polymeric monofilaments form a first arched row when the first and second base strings are brought together. Several types and configurations of brushes are made using either arched bristles or combinations of arched and straight bristles.
