Definitions

  • the invention relates to a tool designed in particular as a slip ring or grinding wheel for the mechanical surface treatment of an object by rubbing, for. B. for brushing, polishing, shining, cleaning, wetting or drying, which consists of a cut and processed fleece made of fibers.
  • the mechanical surface treatment takes place in particular for the processing of numerous products made of metal, wood, stone, glass, leather, plastic and the like.
  • the surface treatment is done e.g. B. when polishing in several steps using different tools or tool configurations, which produce an increasingly finer surface through selected grading.
  • These tools exist e.g. B. from polishing rings or disks, which are composed of several layers of fabric and are generally arranged on a common axis of rotation or a clamping ring.
  • polishing rings the fabric cut into strips is folded, placed in a ring around a core, which consists of cardboard rings or flanges or a metal clamping ring, and fastened to or with it.
  • Slices of cut fabric layers are placed on top of each other and z. B. twisted by an angle of 30 °, sewn and held together by attached cardboard flanges.
  • the fabric used for this purpose is a cotton fabric in general, but especially for polishing.
  • tissue made of stiffer fibers e.g. B. sisal can be used.
  • Certain polishing rings or disks can also be made from a mixture of construction wool and sisal fabric.
  • the polishing rings or disks can optionally be impregnated with a resin serving as a binder in order to increase their strength.
  • the fabric consisting of cotton or other unmixed or mixed fiber materials has still to be biaized before being cut and processed into fold rings.
  • This is understood to mean the inclination of warp and weft threads to form a cut edge which runs obliquely to the original selvedge.
  • a special turning machine is required for this process, which sews the edges of the fabric together to form a tube.
  • the fabric tube is then cut into strips in a helical shape (biaised) and rolled up into a bale.
  • the threads form an angle of 45 ° on the periphery of the fold rings.
  • the problem of fraying the fold rings is to be counteracted by means of the biaization (cf. magazine L'Usine antibiotic, March 1961, "Techniques Moderne de Bufflage et de Pollisage").
  • polishing ring By folding the fabric bands, the polishing ring is automatically ventilated during the rotation; it obtains the necessary suppleness to better encase the part to be polished and forms honeycombs on the periphery which receive the polishing pastes. Polishing pastes are always required when polishing surfaces because of their grinding and lubricating properties.
  • the conventional polishing tools however, have both economic and technical disadvantages. These are in particular the following:
  • FR-PS 1 426721 describes, for example, a polishing or grinding material made of fleece, which consists of synthetic, permanently corrugated filaments. This will be an adhesive with or without abrasive particles applied to the filaments under tension. If the tension is interrupted, the fibers intertwine and are then thermofixed. The fleece thus obtained is cut into an annular polishing tool and processed.
  • FR-PS 2310 838 also describes polishing rings which consist of several layers of non-woven material. The disordered fibers of this fleece are connected at their intersection points by means of a resin.

Hair elements contains and in which cavities of the tangle are included grinding or polishing grains with a grain size below 1000 microns.
  • the felt body should be treated with a stiffener, the proportion of stiffening additives in the felt body being at least 40%.
  • water-soluble, thermoplastic additives with a dry content of 20 to 50% polyvinyl acetate dispersions serve as the stiffening additives. The resulting stiffness of the felt body makes it unsuitable for many applications.
  • the object of the present invention is to provide a tool of the type mentioned at the outset which, while avoiding the disadvantages mentioned above, is easy to manufacture and has a long service life, and can be used reliably, in particular also for objects with uneven surfaces.
  • This object is essentially achieved according to the invention in a tool of the type mentioned at the outset by using an exclusively mechanical process as a flexible, non-woven fabric with a mechanical strength of 150-500 which allows the object to be immersed and at least partially enveloped under the treatment pressure N / 500 mm, preferably at least 300 N / 50 mm, and an average elongation at break of 50-150%, preferably 80-100%, according to DIN 53 857/2.

  • the grinding or polishing paste can be added separately depending on requirements and consumption; there is no need to keep the abrasive or polishing grains in the nonwoven fabric.
  • the flexibility and the immersion behavior of the tool can be further optimized by the fact that the random fiber fleece has a falling capacity, i.e. has a case coefficient D according to DIN 54 306 between about 70 and 90%.
  • the mechanical nonwoven formation process is carried out either by the needling process known per se or by means of a liquid and / or gas jet, which results in a surprisingly stable random-fiber nonwoven which is particularly suitable for the purpose of the invention and which meets the requirements for a tool for fulfills the mechanical surface treatment by rubbing particularly well with a long service life.
