Definitions

  • This invention relates to the production of rotary driven brushes. More particularly, the invention relates to the production of brushes for road-sweeping vehicles or any other mechanically driven rotary sweeping machines.
  • road-sweeping brushes brushes for road-sweeping vehicles
  • a plywood base in which are formed a series of holes for receiving bunches or tufts of bristles, which are then folded through the holes and secured to the wooden base, for example by stapling.
  • the present invention in one aspect provides a method of making a rotary driven brush, comprising arranging bunches of bristles so that their one ends extend into a mould for forming the brush base, and applying into the mould around the said one ends of the bristles a quick-setting liquid plastics material. and allowing the plastics material to set to secure the brush base to the bristles.
  • the plastics material will be one which sets in a relatively short time, and is most suitably any' elastomeric polymer material having a micro-cellular structure.
  • a particularly suitable material has been found to be polyurethane modified to be marginally foamed, for example by adding water thereto, but any other material meeting the requirement of quick setting may be used in the invention.
  • polyurethane or any other suitable material
  • a micro-cellular structure may equally be obtained in other ways, for example by air injection or by filling the polymer material with low density articles such as hollow glass spheres.
  • Polyurethane in which slight foaming is induced by water absorption may suitably have a specific gravity of about 0.7.
  • the plastics material flows easily and will set and harden around the bristles in about 3 minutes, using a polyurethane as described above.
  • road-sweeping brushes and other rotary driven brushes can be produced much more quickly than hitherto, and in addition the whole brush base is manufactured in a single operation, whereby there are avoided areas of weakness as occur in the road-sweeping brushes of the prior art.
  • the bases of brushes manufactured according to the invention thus have high impact resistance, leading to low failure rate.
  • the brush bristles may be suitably made of a plastics material, although of a material different from that of the plastics base, for example, polypropylene or nylon, but other thermoforming extrudable materials could be used.
  • the bristles may be made of horsehair or wires for example.
  • the base When the method of the invention is utilized for producing road-sweeping brushes, the base will be usually annular, with bunches of bristles extending obliquely outwards from the plane of the annular base.
  • an annular mould above which is arranged a jig for holding bunches of bristles at an oblique angle with their lower ends disposed within the mould.
  • a suitable micro-cellular elastomeric polymer material is then filled into the mould and allowed to set and harden around the bristles, within a few minutes.
  • the moulding is then removed from below the jig and placed in a drying area, with the bristles supported by a drying jig which may be simply a circular hole of greater diameter than the base mould formed in a plate arranged above the mould. After drying, the completed brush is then removed.
  • Figure 1 shows a road-sweeping brush produced according to the invention which comprises an annular base 1 foamed of micro-cellular elastomeric polymer material, e.g., polyurethane foamed by adding water thereto, and bunches 2 of polypropylene bristles having their one ends 2a secured in the base 1 and being disposed so as to extend obliquely outwards from the base.
  • annular base 1 foamed of micro-cellular elastomeric polymer material, e.g., polyurethane foamed by adding water thereto
  • bunches 2 of polypropylene bristles having their one ends 2a secured in the base 1 and being disposed so as to extend obliquely outwards from the base.
  • bristles extend obliquely with respect to the base as shown in Figure 1. it will be understood that the bristles may extend at any angle from vertically upwards to radially outwards with respect to the base.
  • Such a brush may be suitably produced in the following manner, in which reference will be made to Figures 2 and 3.
  • the bristles are arranged in bunches and their one ends 2a are applied onto a hot plate to fuse them together.
  • the bunches 2 of bristles are then placed to be held by a jig ( Figure 3) which comprises an annular plate 5 having therein a series of holes or other apertures 5a in which the bristles are placed with their lower ends 2a resting in an annular mould 3 (better shown in Figure 2).
  • the jig 5 is supported in position by any suitable means 6.
  • the mould 2 has four equiangularly spaced recesses 3a formed in its outer periphery, for forming spaces for receiving bolts when the finished brush is installed on a road-sweeping vehicle.
  • the mould 3 also has four jig supports 4.
  • the micro-cellular elastomeric polymer material is poured into the mould 3 and allowed to set and harden around the ends 2a of the bunches of bristles, which procedure takes a few minutes only.
  • the polymer material also penetrates to some extent between the individual bristles of each bunch 2.
  • the moulding of the thus formed brush base 1 is then removed to a drying area.
  • the bristles may be conveniently supported by a drying jig (not shown) which may take any form but which is conveniently a plate with a single central aperture of greater diameter than the mould 3, against which aperture the bristles rest.
