Abstract

A method of creping a web including supporting the web on a drum and rotating the drum to move a first length of the web proximate to a creping blade such that the creping blade removes the first length from the drum. The creping blade has first and second sections made of a base material. The base material has a first coefficient of friction at the first section and is processed to produce a second coefficient of friction at the second section greater than the first coefficient of friction. The method includes moving the first length along the first section, removing a second length of the web from the drum with the creping blade, moving the first length along the second section, forming the second length into at least one microfold as the first length contacts the second section, and forming the second length into at least one macrofold.
