ABSTRACT:
Curl removing bars are employed in prior art paper processing such as paper coating to remove the curl from paper stored on a supply or storage roll. The curl removing bar is usually aligned parallel to the axis of rotation of the supply or storage roll. The curl removing bar is subject to wear due to the friction of the paper sliding over the bar. The invention provides a curl removing bar assembly including a ceramic cover which rests upon or is fastened to a curl removing bar for preventing frictional wear of the curl removing bar. The ceramic cover contacts the sheet material to remove the curl.
