A roll covering includes a functional layer formed of a polymer which is a blend of at least one rubber and one millable polyurethane rubber. The polymer includes from 65% by weight to 85% by weight of the at least one rubber and from 15% by weight to 35% by weight of the millable polyurethane rubber. A roll having the roll core, a method of using the roll and a combination of the roll and a heated drying cylinder are also provided.

The problem of deck channel rewetting that occurs when a drainage chamber in a roll upwardly approaches a horizontal line extending past the horizontal diameter of the roll is solved by using a comb plate comprising at least one comb tooth engaging the perforated plate and extending through a deck channel to a drainage channel such that the at least one comb tooth has a slope configured to direct a slurry suspension from the perforated plate into the drainage channel.
