Abstract: 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.
