Abstract

Official abstract text for this publication.

A vacuum roll includes an inner rotor, an intermediate stator, and an outer shell roll. The inner rotor has open and closed portions and is adapted to rotate within the intermediate stator which is rotationally fixed and also has open and closed portions. The outer shell roll has open and closed portions and is adapted to move around the intermediate stator. Together the inner rotor and the intermediate stator define an internal rotary valve interface adapted to control fluid communication between the interior chamber and the outer shell.
