Abstract

The invention involves methods and tools to condition the glaze (10) on the rollers (10) in papermaking machines where the coating is either ceramic or metal-ceramic. The rolling ball (10) is treated as Period With the abrasive unit (21) attached to the repair part (19) of the roller (10) the size of the abrasive grain in the abrasive unit (21), the average center line is approximately 15 .. .200 um.During sanding, the rollers (10) are rotated at the operating position and the abrasive unit (21) is pressed hard to provide Contact with the surface To be reconditioned Which if the surface to be treated is too rough, it will be smoothed until Get the required roughness value.On the other hand, the surface is smooth until Too rough will be made up until the roughness value. Who wants Set by unit for abrasive (21)
