Abstract

METHOD FOR MANUFACTURING A STONE ROLL FOR A PAPER MACHINE A method for manufacturing a stone roll, particularly a press roll, of a paper machine is characterized by grinding the cylindrical shell of the stone roll to its final shape at substantially the same temperature at which the stone roll will operate in the paper machine. In this manner, a significant drawback, wherein stone rolls ground to perfect straightness and ultimate gloss tend to develop temperature-induced deflections which in turn cause non-uniform distribution of the nip pressure manifesting itself in a non-uniform moisture profile of the web treated in the press, is eliminated.
