发明名称 TISSUE IMPULSE DRYER
摘要 A tissue dryer has a dryer roll which is externally heated by induction to raise the roll surface temperature to between 300-700 DEG 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.
