Abstract
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.
