  • Method for balancing a cylinder, roll or equivalent part with a thin mantle and balanced cylinder, roll or equivalent part with a thin mantle
    Patent number: 6370953
    Abstract: A method and apparatus is disclosed for balancing a cylinder, roll, or equivalent part, with a thin mantle, by which deviations in the circumferential deflection line of the mantle can be compensated in order to correct for dynamic runout. Errors in the circumferential deflection line are measured and dynamic runout is determined. Locations and magnitudes of any counterweights necessary for balancing are determined based on deformations and dynamic runout arising from deviations in the deflection line of the mantle. Counterweights are fixed to the inner face of the mantle of the cylinder, roll or equivalent part at positions determined from measurements.
