Abstract
A suction box for use in drying a felt web in a papermaking machine has one or more cover members in contact with a surface of the felt web. The surface of at least one of these cover elements which normally contacts the felt web has a leading portion which is feathered or inclined away from the surface of the felt web in the direction opposite the direction of motion of the felt web. This allows the felt web to come into contact with the cover member surface more gradually, which reduces wear on the felt.
