Abstract
The ventilator is to be disposed between rows of drying cylinders in papermaking machines in order to feed dry air and evacuate moist air during the drying operation of papermaking. A method of ventilating an offset pocket is also disclosed. The ventilator includes a ventral face and a dorsal face. The ventral face comprises at lea st one ventral orifice disposed adjacent to the wire and the dorsal face comprises at least one dorsal orifice disposed adjacent to the web being carried by the wire. The ventral orifice discharges air into the path of the wire such that the fluid traverses the wire to the other side and then goes into the offset pocket. The dorsal orifice discharges air in a direction opposite the direction of travel of the portion of the web being carried by the wire. The ventilator improves the ventilation of offset pockets.
