A limiting orifice through-air-drying apparatus for papermaking or other absorbent embryonic webs. The apparatus has a first zone (41) and a second zone (42). The first (41) zone is maintained at a differential pressure less than the breakthrough pressure, while the second zone (42) is maintained at a differential pressure greater than the breakthrough pressure. The residence time of the embryonic web to be dried with the apparatus is maintained at preferably less than 35 milliseconds on the first zone. Using the dual zone system described above, the overall energy required to run the apparatus can be reduced.

L'invention concerne un appareil de séchage par air à orifice limitateur, destiné à être utilisé dans la fabrication du papier ou autres bandes embryonnaires absorbantes. L'appareil comporte une première zone (41) et une seconde zone (42). La première zone (41) est maintenue à une pression différentielle inférieure à la pression de passage, tandis que la seconde zone (42) est maintenue à une pression différentielle supérieure à la pression de passage. Le temps de séjour de la bande embryonnaire devant être séchée par l'appareil est maintenu de préférence en dessous de 35 millisecondes sur la première zone. Grâce à ce système double zone, l'énergie totale nécessaire pour faire fonctionner l'appareil peut être réduite.
