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.

Continuous drying apparatus for porous web

The present invention is directed to a technique on a continuous drying apparatus for porous web, which comprises a heating cylinder, an impermeable drying band impermeable to air and water, coming into contact with and supporting the surface on the side having no contact with the heating cylinder of the porous web, and a plurality of water lubricating shoe members arranged around the heating cylinder apart a desired distance from the external side of the impermeable drying band, for forming a water screen flow between them and the external surface of the impermeable drying band, whereby an effective drying of the porous web is achieved.
