Method of producing pulp moldings |
摘要 |
A method of producing pulp moldings having a paper-making process comprising the steps of assembling split mold halves (11, 12) having suction passageways (14) to form a paper-making mold (10), feeding pulp slurry of predetermined set feed concentration into the cavity (13) in the paper-making mold (10), and sucking the pulp slurry through the suction passageways (14) to form a pulp layer (15) on the inner surface of the paper-making mold (10), wherein the concentration of the pulp slurry in the cavity (13) in the initial and/or final period of formation of the pulp layer (15) in the paper-making process is lower than the above-mentioned set feed concentration of the pulp slurry.
