<p>METHOD OF BRUSH MANUFACTURE A method of manufacturing brushes wherein two brush tapes which are formed of synthetic resionous material and incorporate a plurality of bristle filaments held together by a knitting operation or by a weaving operation or by means of an extruded bead are arranged adjacent each other and held in this relationship by means of a bead of synthetic resinous material running along one side edge of the tapes. This bead may be extruded around the adjacent edges of the tapes or if beads of plastics material are already present on the tapes, may be formed by fusing the two beads together. There may be more than two adjacent tapes which may be arranged side-by-side or at an angle to each other or spaced apart and the construction of the tapes can be the same or different. Furthermore, one or more barrier layers may be located between the tapes.</p> |
