Abstract:
In laminated, resin-impregnated doctor blades for removing water from a grooved belt in the press part of a papermaking machine, fibers of the belt-contacting layer are oriented in the direction of travel of the belt. The doctor blade so constructed exhibits greater adhesion to the belt, an improved water-removal capability, and greater durability, when compared with a doctor blade having randomly oriented surface fibers.
