  • Patent number: 6772467
    Abstract: A bristle for brushware or brushes is described. The bristle is produced through cutting an extruded monofilament to length and tapers towards its useful end to form a kind of tip. The bristle is characterized in that it consists of at least two coextruded plastic components and has a shaft of a soft, elastic plastic material and a core of a harder elastic plastic material. The core projects past the shaft at its useful end thereby forming the tip. The bristle can also have a reinforcing jacket which surounds the shaft of the envelope. A method for producing such bristles is also described.
