Abstract:
A vacuum roll has an inner cylinder defining an interior chamber. The interior chamber is fluidly connected to a vacuum source for applying a vacuum thereto. An outer cylinder is rotatable about the inner cylinder and has a plurality of apertures therein. An actuator is configured to move the inner cylinder between a first position and a second position. The vacuum roll has a first vacuum profile with the inner cylinder in the first position and a second vacuum profile with the inner cylinder in the second position.
