Abstract: A pocket ventilation roll baffle assembly adapted for use in drying a paper web is disclosed. The pocket ventilation roll includes a stationary tubular inner core roll, a tubular outer shell roll mounted for rotation in concentrically spaced relation about the inner core roll, and a device for supplying drying air within the inner core roll. The drying air flows longitudinally through the inner core roll and radially outwardly through an arcuate portion of longitudinally arranged perforations contained in the inner core roll and circumferential perforations contained in the outer shell roll. The pocket ventilation roll baffle assembly includes a baffle arrangement for adjusting the profile of the drying air flowing radially outwardly from the pocket ventilation roll.
