Abstract

A method of manufacturing brushes wherein two brush tapes which may be formed in accordance with the teachings of our U.K. Patent No. 1457074 or our Patent Application No. 7901230 or our Patent Application No. 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.

Description

  • This invention relates to a method of manufacturing brushes.
  • In our U.K. Patent No.1457074, a method of manufacturing brush components is disclosed wherein a plurality of endless bristle filaments are folded into a zig-zag formation and held in that position by means of threads knitted into the zig-zag, the resultant tape then being slit centrally and having plastics locking beads extruded onto it either before or after slitting. In our subsequent co-pending U.K. Patent Application No.7901230 further methods of brush construction are disclosed wherein beads of plastics material are extruded onto aligned bristle elements held between endless haul-off belts. It is also possible to manufacture brush components by taking a tow of endless bristle elements and weaving this with a suitable warp yarn to provide a woven fabric which subsequently has plastics beads extruded onto it transverse to the tow wefts and is slit into brush component tapes. The longitudinally extending knitted or woven brush component, with or without its extruded plastics beads, and the components formed by the methods disclosed in our said Patent Application No.7901230, will hereinafter be referred to as brush tapes.
  • The present invention seeks to provide an improved method of manufacturing brushes, which method incorporates the use of brush tapes as described above.
  • According to the present invention, we provide a method of manufacturing a brush component wherein at least two brush tapes having a plurality of aligned bristles are arranged adjacent each other and are held in this relationship by means of a bead of synthetic resinous material running along one side edge of the tapes, the said bead acting as an anchoring device for securing the brush component in a brush holder.
  • In one construction, for example, if the tapes are knitted or woven tapes, the two tapes can be held in abutting side-by-side relationship and have the bead extruded along their abutting side edges. Alternatively, if the tapes are formed by a different method and/or already have beads along their side edges, then the existing beads along their side edges can be fused together to provide a single anchoring bead.
  • If desired, several tapes may be arranged in side-by-side relationship and these may be of similar or of different construction. For example, the tapes may be formed of the same or different bristle components or they may be of different densities or thickness or the bristles or tows or bundles into which they are formed may be of different diameter.
  • In order to strengthen the brush component, a carrier may be incorporated in the bead and this may be in the form of a coated or uncoated wire or textile filament. If a wire is provided, this will mean that if the component is bent to a particular shape, it will maintain that shape.
  • In a particular embodiment of this invention, one or more barrier layers, e.g. cloths or impervious membranes may be incorporated into the component. The membrane can be a single sheet of plastics material located between the two tapes, e.g. a polymeric sheet which would fuse with the material of the bead, or, alternatively, a plurality of individual overlapping membranes could be provided. If desired, the membrane may be pre-formed into a generally pleated construction and by spacing the two brush tapes slightly apart, the pleated membrane can then be accommodated between the tapes. Obviously, the closer together the tapes are located, the more the bristles on each side of the tape will be accommodated in the indentations provided by the pleats. With such a construction, the resultant brush component would not lose any of its flexibility in the longitudinal direction and could be flexed easily about its bead, and if an impervious membrane is used, the brush could be largely waterproof.
  • If desired, the two or more tapes making up the brush component could be orientated relative to each other so that instead of lying side-by-side, they are inclined to each other with only the edges of the tapes to which the bead is applied being adjacent each other.
  • Alternatively, the tapes could be slightly spaced apart.
  • In both these constructions, a membrane may be provided between the tapes.
