Abstract
A creping blade for creping a cellulosic web from a rotatable cylinder in a creping process includes first and second side faces. The first side face is at least substantially opposite to the second side file. The blade also includes an upper surface adjacent to the first and second side faces. A plurality of notches is provided along the upper surface. Each of the notches has a bottom portion and an open end defined by at least a portion of the upper surface. The notches are configured to increase the caliper of the cellulosic web when the creping blade crepes the cellulosic web from an outer surface of the rotatable cylinder. Creped paper and improved methods of manufacturing paper are also provided.
