Yankee Dryer Dry Creping Basics

Online Course Description:
The Yankee dryer is a large, steam-heated, pressure vessel that is used in the production of tissue grades. After the tissue sheet is dried by the Yankee dryer and Yankee hoods to its final moisture target, it is creped and removed from the Yankee by the creping doctor. The dry creping process is responsible for the bulk, stretch, and softness that are desirable in tissue grades. This course describes what happens to the sheet during dry creping, factors that influence dry creping results, the design and operation of the creping blade, and blade angles and sheet angles associated with the creping blade.
