Paper Machine Suction Rolls and Roll Covers

Though their design and construction are very similar, suction rolls perform several different functions on paper machines, depending on their position. They can be used to remove water from the sheet, transfer the sheet, improve dewatering in a press nip, dewater a felt, stabilize the sheet, or pull steam into the sheet. Roll cover selection should take into account the functions of the roll and the operating conditions.
