Summary:PURPOSE: To extremely shorten a drying time and to enable drying at a low temperature. CONSTITUTION: A forming solution containing at least a fiber material in a dispersed state is separated from a liquid component by a scooping net by removal of the solution to give a formed web in a hydrous state. Hot air is sent from the top of the formed web in a hydrous state and the lower space under the scooping wet is made into an evacuated state. The formed web is dried by passing the hot air through it. A thick and a heavy formed webs can be readily dried to an absolute dry state and a formed web in a hydrous state can be dried with slight heat history.
