Title (EN) TISSUE IMPULSE DRYER
(FR) TRAIN DE SECHAGE PAR PRESSAGE FORCE ET CHAUFFAGE POUR PAPIER MOUSSELINE
Abstract:
(EN) A tissue dryer has a dryer roll which is externally heated by induction to raise the roll surface temperature to between 300-700 °F while allowing internal hydraulic crown support of the roll. The hydraulic support of the roll exerts pressures of between 1 000-10 000 pounds per linear inch. The drying performance of the dryer is enhanced by providing a prewarp of the web onto the hot roll just before the pressing nip. After the web transits the nip it is removed by a doctor blade which crepes the web. The web is fully restrained during the majority of the drying process thus requiring no adhesive sprays.
(FR) Ce train de séchage pour papier mousseline comprend un rouleau de séchage chauffé de l'extérieur par induction, ce qui élève la température de surface de ce rouleau jusqu'à 300 à 700 °F tout en autorisant l'utilisation d'un support interne hydraulique en couronne lequel exerce des pressions allant de 1000 à 10 000 livres par pouce linéaire. Les caractéristiques de séchage de ce train de séchage sont améliorées par un guide de bande disposé sur le rouleau chauffé juste devant la ligne de pression. Quand la bande a traversé cette ligne, elle est retirée avec un docteur qui crêpe cette bande tandis qu'elle est intégralement maintenue pendant l'essentiel du processus de séchage, n'exigeant ainsi aucune pulvérisation d'adhésif.
