Abstract:
A method for producing a pulp molded article comprising the steps of supplying a pulp slurry under pressure into a cavity of a mold composed of a set of splits in such a manner that said cavity is pressurized, the set of splits being assembled together to form said cavity with a prescribed configuration, to form a pulp deposited body, feeding a first fluid into said cavity to press said pulp deposited body onto an inner wall of said cavity thereby to dewater said pulp deposited body, taking said dewatered pulp deposited body out from said mold, setting said pulp deposited body in a separately prepared heating mold which is composed of a set of splits and heated to a prescribed temperature, inserting a pressing member into a cavity of said heating mold, feeding a second fluid into said pressing member to inflate said pressing member and to press said pulp deposited body onto an inner wall of said cavity thereby heating and drying said pulp deposited body.
