ABSTRACT:
A fibrous web is uniformly adhered to the surface of a smooth creping cylinder or other creping surface without causing substantial compression of the web. A raised pattern is pressed into the web toward the creping cylinder to cause the portions of the web that are pressed to adhere more strongly to the creping surface, while the portions of the web that are not pressed remain more lightly adhered to the creping surface. The web is creped from the creping surface with a creping blade, and the resulting product has a pattern creped appearance wherein the portions of the web that are pressed are finely creped while the portions of the web that were not so pressed are coarsely creped.
