Flywheel for coating rolls

A coating roll assembly comprising:

• a motor coupled to a coating roll for rotating the coating roll around an axis;
• a flywheel for damping radial vibrations of the coating roll relative to the axis of rotation of said coating roll comprising;
• a first planar plate element;
• a second planar plate element;
• planar layer of damping material;
• fasteners to prevent torsional motion;
• means for fixing said plate elements to said coating roll perpendicular to said axis of said coating roll and for preventing torsional movement between the coating roll, said plate elements, and said damping material around the rotating axis with said fasteners;
• said planar layer of damping material captured between and contacting each of said planar plate elements wherein torsional movement between said first planar plate element, said second planar plate element and said planar layer of damping material is prevented by said fasteners;
• whereby radial movement of said coating roll relative to the axis of rotation of said coating roll causes said plate elements to compress said layer of damping material to damp said vibrations by means of compression between said plate elements and said layer of damping material.
