ABSTRACT:
Brush bristle assemblies are formed into strips with strips of length of thermoplastic monofilaments which are mutually fused at their bottoms and formed into coupling bars with snaps fastening heads. The bars are slidably coupled to linear or helical channels or slots formed in rotary driven brush drum bristle substrates. In one form, the individual monofilament lengths are bent to form dart shaped loops. The bent thermoplastic lengths are longitudinally stacked with the apices of the contiguous loops being mutually fused to form a bristle strip. A hand brush is formed of a bunch of polypropylene filaments, the bottom section of which being mutually fused and shaped to form a bristle base and handle.
