Abstract
A continuous drying apparatus for a porous web including a porous web for traveling on a drying line, a heating cylinder for contacting the porous web at its circumferential surface and rotating in synchronization with the travel of the porous web to heat the porous web, a drying band for contacting and supporting a surface of the porous web which is out of contact with the heating cylinder and also for rotating in synchronization with the travel of the porous web, and a pressure rotating body disposed near the circumference of the heating cylinder and outside the drying band. The pressure rotating body is constructed of a rotating member for rotating and contacting an exterior surface of the drying band and a pressure device for pressurizing the rotating member toward the heating cylinder. With this, a porous web can be efficiently dried.
