<p>A covering (2) for a steel roll (1) consists of fiber reinforced material. The outer layer (6), e.g. 8 mm thick, is a highly elastic material with a damping factor tan delta less than 0.02. The inner layer (5), e.g. 12 mm thick, is of a material with a high damping factor of tan delta greater than 0.05.</p> |
