from the wheel side) because the bearing clearance is zero there. When the roll is back in the paper machine, the nip force will take the bearing clearance to zero and it is desirable to have the best concentricity towards the nip. Figure 1: Simple profile measurement may be done at the mill or at an outside roll shop. Published September 13, 2013 Practical Roll Techniques: Grinding

be used in machines with longer rolls to maintain the degree of stiffness required for holding the rolls in position. Larger diameter rolls have a better roll (corrugation) life since the increased diameter improves the nip angle, making it easier for the rolls to pull material into the nip. This reduces slippage in the roll, a major source of
