Definitions

  • the present invention relates to a sanding tool a particularly fit to sandpaper, to sand, to remove paint, to polish, to eliminate working scores and/or burr tracks, to smooth and to round off peripheral edges and/or to finish panels, shutters, planes, plates and the like, also with relieved or concave portions, made of any natural or synthetic materials.
  • pads There are known sanding tools, known as pads, provided with an almost disc shaped body whose face has a coupling shaft to a mandrel or to an attachment of a device o machine in order to sand or smooth.
  • the opposite face of this body has a plurality of protruding sanding means, in general comprising sanding paper or abrasive cloth.
  • the shaft is rotated by the tool or by the machine in such a way that the protruding sanding means move quickly over a surface sanding it.
  • a tool in accordance with the preamble of claim 1 is known, for example, from GB-A-2 342 850 .
  • the sanding means are irremovably blocked to the body making the whole tool useless when the sanding means are worn out and exhausted.
  • a drawback of said known sanding tool is that they may exclusively use sanding means having the enlarged side complementary and compatible with the tool throats.
  • throats of the known tools may house sanding means only with certain defined types of sanding paper or cloth having thicknesses being in a predefined value range compatib le with the dimensions of the enlarged sides of the sanding means suitable for said throats.
  • throats may amass powders and working residuals preventing from or making difficult the sliding and the removal of the exhausted or to be substituted sanding means.
  • An object of the present invention is to propose a sanding tool re-usable even if the sanding means are exhausted through partial or total substitution thereof; another object is to propose a sanding means whose paper or cloth may be substituted allowing to use again the other elements of the sanding tool like brushing means or the like.
  • Another object of the present invention is to propose a sanding tool which may use sanding means having enlarged sides almost of any shapes, dimensions and papers or adhesive ribbon, and thickness.
  • Further object of the present invention is to propose a tool fit to keep also sanding means in which the sanding paper or ribbon is not glued or irremovably fixed to is brush support or of another type.
  • Another object is to propose a sanding tool without throats and thus almost without sliding problems and sanding means substitution problems.
  • the invention is defined in claim 1.
  • connection means 4 for instance for a rotation shaft of a device or of a machine or mandrel type and similar.
