Definitions

  • the present invention relates to a method and a device according to Generic term of the independent claims.
  • Grinding rollers are leveled by means of a dressing device, such as in CH 281 392 has been disclosed. These devices use a dressing element, which is arranged above the sanding roller.

  • the clothing wires are not in this second section directed downwards towards the drum but upwards.
  • a second possibility of grinding the flat bars is that the flat bars are removed from the card and on a special Grinding machine to be ground.
  • This grinder is for example from a full sanding roll with arranged above it, movable Carriage for holding 1 to 4 lids. When grinding leads the Slide the lids over the roller constantly back and forth until they are on one exactly set height are ground down.
  • Grinding rollers for grinding sets of fiber treatment rollers are known per se and when grinding depending on whether tambour or takers in the upper or upper region of the roll to be ground stated.
  • Object of the present invention is thus a method and a To provide device with which above-mentioned disadvantages avoided be and with which fiber treatment rollers and in particular the Flat bars also give each other the correct height and uniformity of Have trimmings.
  • a flat bar for a card is the first flat bar to be measured clamped on the side.
  • This clamping can be done in a separate measuring device done or in an advantageous manner in the grinding device itself, so that the flat bar ground in a clamping and then is measured.
  • the flat bar is clamped so that he is bent according to its own weight in itself. advantageously, show the cover sets of the first flat bar after above.
  • the flat rod is loaded with a compensation device, which compensates for the "wrong" deflection of the flat bar to that a deflection as in the installed and carded state is simulated in the card. On the treads of this first flat bar a counterpart is launched.
  • this gap at least at some points of the length of the Dekkelstabes measured to see if the grinding process performed correctly has been. If the gap has different thicknesses, it is assumed that an error occurred during the grinding of the flat bar is, whereby the grinding process with changed settings too is repeated or the grinding system has to be corrected.
  • the gap with a spacer of a defined size between the running surfaces of the first flat bar and the counterpart or the running surfaces of the second flat bar is generated.
  • the spacer causes, in particular, when stacking two flat bars the polished trimmings have a distance from each other, which checked for its uniformity over the entire length of the flat bar can be.
  • the distance between the flat bar and counterpart is to choose so that a gap is formed, which then measured can be.
  • the gap should not be too large, so tolerances in the subsequent measurement are to be kept low.

Otherwise, it is advantageous if the Compensation device is attached directly to the chuck. This ensures that the compensation device the flat bar always keeps in the intended opposite bend and thus a precise and uniform grinding process allows. In particular, in the arrangement on the carriage of the linear guide for the clamping device is so ensures that the compensation device together with the Carriage and the clamped flat bar is moved and thus no Relative movement between compensating device and flat bar takes place. An exact adjustment of the compensation device with respect to the flat rod to be ground is thus guaranteed.

  • the dressing element is preferably in relation adjustable to the surface of the grinding device.
  • the clamping device has a stop for defined recording of the flat bar, in particular with respect the tread of the flat bar. After the tread of the flat bar a significant area for the exact assignment of the flat clothings a drum set in the card is, it has to be particularly advantageous exposed when the jig the lid on the tread defined detected. Thus, the distance between tread and tips of Cover set exactly determinable and the clamping device with respect to Grinding device accordingly adjustable.

If both flat bars are the same have been ground, is the gap, which between the flat clothings arises, evenly over the entire length of the flat bar. If an error has occurred during the grinding process, the Thickness of the gap differ from the other locations. This is a Sign that the flat bar must be sharpened again, until a uniform gap over the entire length of the flat bar originated.
