Flooding edge showers may also be located near the flooded nip shower to continuously remove the trimmed edges from the wire. In the press section, a flooding shower is sometimes installed at the roll felt nip, just before the felt suction box. It helps flush contaminants from the felt and maintains a uniform water distribution in the felt.
