Abstract
A transfer system for transferring a moving wet cellulosic web between two moving elements of a paper machine without excessive sheet flutter or breakage, supports the web and permits higher web speeds than presently used. The transfer system comprises a suction roll that forms a nip in contact with the web on the surface of a roll or web supporting belt, a doctor blade positioned in contact with the surface of the roll or web supporting belt immediately after the nip to ensure the web separates from the surface, and an air jet adjacent the doctor blade that blows air in a direction substantially opposite the moving web, between the moving web and the surface of the roll or web supporting belt, to guide and support the web towards the suction roll.
