Sheet Wrap

Ready
Synonym: by-passing

Definition: Sometimes, especially at start ups,  the tissue sheet will stick excessively hard to the surface of the Yankee and will pass under one or more doctor blades wrapping multiple layers of tissue, glued together by the organic coating, on the surface of the Yankee.  Width us usually in narrow bands but can be as wide as the full sheet.  NOTE:  Sheet wraps are a very dangerous situation and must be prevented or be addressed immediately to prevent harm to personnel or equipment.
