A paper web drying apparatus is described as comprising a device for controlling an injection of air in a drying pocket of the drying apparatus. The web drying apparatus generally comprises at feast three substantially axially parallel rotatable drying cylinders, first and third cylinders being vertically offset from a second cylinder and the web being consecutively trained thereover defining the pocket therebetween. The apparatus may define a traditional pocket, an offset pocket, or other such pocket configurations known in the art. The device comprises an elongated structure longitudinally mounted adjacent and substantially parallel to the first cylinder and between the first and the third cylinders. A first lateral edge of the structure may be positioned proximal to a peripheral surface of the first cylinder thereby defining a gap therewith such that the web trained thereon may travel toward the second cylinder unobstructed by the structure while the structure reduces an inflow of air dragged into the pocket by a motion of the web from me first to the second cylinder.
