Definitions

  • the present invention relates to a lining carrier for a sanding shoe lining, in particular for use with a sanding shoe for pressing grinding surfaces on workpieces in segment and wide-belt sanding machines.
  • the lining carrier has an abrasive coating which has at least one flat, padded and / or lubricious contact surface.
  • the invention relates to a Schleifschuhbelag and a method for producing a lining carrier and a Schleifschuhbelages.
  • belt sanding machines For grinding large-area workpieces, in particular of sheets of raw material, such as chipboard, MDF, HDF and OSB boards belt sanding machines are used in the industry. In these belt sanding machines, a wide abrasive belt is driven by rollers and pressed against the surface of the workpiece by means of a sanding shoe.
  • a sanding shoe has to meet several requirements.
  • the friction between the sanding belt and the sanding pad must be as low as possible. Therefore, the sanding pad has a sanding pad which in operation is pressed against the sanding belt and therefore has a lubricious surface.
  • the heat generated by the Anpressreibung should not affect the Schleifschuhbelag, therefore, a heat-resistant material is usually used.
  • the friction created during the grinding process leads to heat generation and wear of the sanding pad cover. Due to the heat development of the lining carrier is also affected. For example, it may lead to deformation of the lining carrier, which require a replacement of the lining carrier. In addition, the replacement is made even more difficult by deformations.
  • EP 1 716 972 A1 describes a replaceable pad shoe covering comprising a pad carrier of non-metallic material.
  • a non-metallic material By using a non-metallic material, a reduced heat conduction takes place. As a result, the frictional heat generated during the grinding process is not absorbed to a significant degree by the lining carrier, and as a result, it is less affected. Nevertheless, it can come to heat transfer to the lining carrier by the compact design.
  • the lining carrier is usually of elongated shape with a longitudinal axis, which in the mounted state transversely or substantially perpendicular to the grinding direction.
  • the lining carrier can be pushed into a recess of a carrier device, and has stop surfaces for absorbing transverse forces.
  • the lining carrier has a surface facing the carrier device in the assembled state, and a surface facing the coating or abrasive material in the mounted state.
  • the object of the present invention is to avoid the disadvantages of the known.
  • a lining carrier for a sanding pad is to be created, which is inexpensive to manufacture.
  • the handling and the duration of the lining carrier should be improved.
  • a lining carrier for a sanding shoe lining in particular for use with a sanding shoe for pressing grinding surfaces on workpieces in segment and wide-belt sanding machines can be provided which has at least one recess.
  • the recess is preferably located on the covering and / or the carrier device facing surface of the lining carrier, and is designed so that the heat exchange via an air cushion hiss the lining carrier and a subsequent to the lining carrier component or a material applied to the lining carrier can be carried out ,
  • Such recesses may be in the form of holes within or through the entire lining carrier, or by depressions on the surface of the lining carrier, preferably grooves.
  • the recess may be stamped, milled or drilled in the lining carrier, or the lining carrier may be pressed or cast into a mold having struts and recesses.
  • the contact surface is essentially retained.
  • material can be applied to a base body, for example, glued as a strip, wherein the recess is formed by the space between the applied materials.
  • the recess is formed by two webs which enclose the recess. Said webs together form a recess, in particular a groove, which preferably extends along the longitudinal axis of the lining carrier.
