If the gap has different thicknesses, it is assume that an error occurred while grinding the flat bar is what causes the grinding process with changed settings repeat or the grinding system needs to be corrected.
  • the gap between each with a spacer of a defined size the treads of the first flat bar and the counterpart or the running surfaces of the second flat rod is generated.
  • the spacer causes especially when laying two flat bars the ground sets are at a distance from each other, which checked for uniformity over the entire length of the flat rod can be.

  • the surface to be sanded Lid set is therefore essentially flat or becomes after the grinding process to be level.
  • the compensation device is arranged on the carriage. Otherwise, it is advantageous if the Compensation device is attached directly to the clamping device. This ensures that the compensation device the flat rod always holds in the intended counterbend and thus an exact and enables uniform grinding. Especially with the arrangement on the slide of the linear guide for the jig ensured that the compensation device together with the Carriage and the clamped flat rod is moved and therefore none Relative movement between the compensation device and flat rod takes place. An exact adjustment of the compensation device in relation to the flat rod to be ground is thus guaranteed.

  • the grinding roller is in the Bracket removably arranged. This makes it possible to use the grinding roller easily removed from the dressing device and with a new one Replace grinding roller. But it is also possible to dress the Grinding roller for grinding fiber treatment rollers in the card use.
  • the grinding and dressing device thus works as a maintenance device for the grinding roller and as a grinding device for the flat bars (double function or "combination device").

  • the Mechanism around whetstone 118 within the dressing tool 117 is not shown here and is not essential to the invention.
  • the spindle 119 is driven by a drive motor 127, which by means of a Coupling 125 is connected to the spindle 119, driven.
  • a control, around the direction of rotation of the drive motor 127 at the end of each Changing the path of the honing stone 118 is not shown here and described and not essential to the invention.
  • the drive motor is 127 provided on a motor base plate 129 which is assigned to the base plate 114 is.
  • the drive motor 128 also rests on a motor base plate 130, which is supported accordingly (not shown).
  • the present invention is not limited to the illustrated embodiments limited. So instead of the reference flat bar 30 is also a counterpart selectable, which has the given ideal line. The resulting one The gap between the ideal line and the flat rod can then be used Measurement of the grinding result can be used. Likewise is one compensation device of a different type than the one shown here can be used, to apply the procedure for measuring the ground lid fittings to be able to. As a grinding device is next to the grinding roller shown a traversing grinding wheel or a grinding block are also possible.
