Abstract
A method of producing pulp moldings having a paper-making process comprising the steps of assembling split mold halves () having suction passageways () to form a paper-making mold (), feeding pulp slurry of predetermined set feed concentration into the cavity () in the paper-making mold (), and sucking the pulp slurry through the suction passageways () to form a pulp layer () on the inner surface of the paper-making mold (), wherein the concentration of the pulp slurry in the cavity () in the initial and/or final period of formation of the pulp layer () in the paper-making process is lower than the above-mentioned set feed concentration of the pulp slurry.
