Definitions

  • the present invention relates to a brush for the surface treatment of materials, and particularly to a brush which can be used in combination with polishing machines for the surfaces of materials which are not perfectly planar in order to confer them a particular polished and glazed effect.
  • Polishing machines for the surfaces of not perfectly planar materials such as granite and preferably, which are useable also with other materials, such as porcelain-e, ceramic, marble and other stones, are already known.
  • Said known polishing machines comprise a rotating drum having one base provided with a multiplicity of abrasive blocks which are oscillated by means of suitable motor-driven devices around axes arranged radially with respect to the axis of rotation of the rotating drum.
  • Object of the present invention is obtaining, by means of the known polishing machines, a new kind of surface treatment which confers to the treated material a particular and pleasant polished and glazed effect which has never been obtained until now by these polishing machines or by other machines for the surface treatment of materials. Said object has been achieved by using in combination with said polishing machines an innovatory brush whose main features are disclosed in claim 1 and other features are disclosed in the following claims.
  • the brush according to the present invention can be advantageously mounted in the known polishing machines in place of the oscillating abrasive blocks which carry out the polishing treatment.
  • the known polishing machines which are generally available in every workshop where the surface treatment of materials is carried out.
  • the bundles of abrasive bristles are advantageously arranged in a substantially radial orientation with respect to the rotation center of the rotating drum, so that the risk of scratching the materials to be treated is avoided.
  • the ends of the bundles of abrasive bristles are comprised within a substantially curved profile, so that an even contact and pressure on the material to be treated during the brush oscillation are obtained.
  • the abrasive bundles are advantageously provided with a flattened profile and are made of nylon coated with corundum or carbide, such as the material named Tynex® of the company DuPont®.
  • the brush according to the present embodiment of the invention is seen to comprise a support 1 preferably made of plastic material and having substantially a parallelepipedal shape.
  • a multiplicity of parallel groovings, particularly four groovings, are made on the larger upper surface of support 1 and in each grooving the end of a bundle of abrasive bristles 2 is inserted and glued, for example by means of a two components epoxy glue.
  • Said abrasive bristles have preferably a flattened cross-section, for instance elliptical or rectangular, and are preferably made of nylon coated with corundum or carbide, such as the material named Tynex® of the company DuPont®.
  • the grain of abrasive bristles 2 can be freely chosen according to the desired effect, however it has been observed that a pleasant polished and glazed appearance can be conferred to most materials by using abrasive bristles having a grain whose index is included between 46 and 320.
  • the groovings whereinto the bundles of bristles 2 are inserted are preferably arranged longitudinally with respect to support 1, so that when the brush according to the present invention is mounted on an oscillating device of the rotating drum of a polishing machine, said groovings are arranged according to a substantially radial orientation with respect to the rotation center of the drum itself.
  • the internal couple of bundles of bristles 2 protrudes from support 1 more than the external couple of bundles of bristles 2, so that the ends of said bundles are comprised within a substantially curved profile, as shown by the broken line of figure 4.
  • the larger lower surface of support 1 is suitably joined to the upper base by an insert 3 which has substantially the shape of a prismoid having the bases and two opposite side surfaces of trapezoidal shape.
  • the upper base of insert 3 is slightly smaller than the lower base thereof, so that a double dovetail joint is obtained with a complementary cavity made in the oscillating device of the rotating drum.
  • Insert 3 is preferably made in one piece of plastic material, for example PVC, with support 1 of bristles 2.
