Abstract:
An apparatus for continuously drying a porous web traveling along a drying line, comprising:a heating cylinder for supporting the porous web on its circumferential surface, said heating cylinder being rotatable in synchronization with the travel of the porous web for heating said porous web;a drying band wound around said heating cylinder for sandwiching the porous web with said heating cylinder, said driving band being rotatable in synchronization with the travel of the porous web;at least one pressure rotating body disposed radially outward near the circumference of said heating cylinder and said drying band; and air eliminating means formed of an air eliminating mechanism and an air removing chamber for eliminating air within said drying band and the porous web, said air removing chamber being provided over said heating cylinder and said drying band,wherein said at least one pressure rotating body includes a rotating member for rotating in contact with an outer surface of said drying band, and means for pressing said rotating member against said heating cylinder to assist said drying band in bringing the porous web into close contact with the circumferential surface of said heating cylinder.
