Abstract
Pulp deposited bodies (7 and 8) are formed on the surfaces (2a and 3a) of a set of splits (2 and 3) of a papermaking mold, each split having a plurality of interconnecting holes connecting the outside to the inside thereof, and the splits (2 and 3) are mated to join the pulp deposited bodies (7 and 8).
Claims35
A method for producing a pulp molded article comprising the steps of depositing pulp fiber on the surfaces of a set of splits for papermaking having a plurality of interconnecting holes connecting the outside and the inside thereof to form a pulp deposited body on each split under such a state that said splits are separated from each other;
- closing said splits to join said pulp deposited bodies together to form a joined body of said pulp deposited bodies;
- and
- feeding a fluid into a pressing member in said joined body to press said joined body onto the inner surface of a mold the cavity of which has a prescribed shape to make said joined body dry.
A method for producing a pulp molded article, comprising:
- depositing pulp fiber on the surfaces of a set of splits for papermaking having a plurality of interconnecting holes connecting the outside and inside of the set of splits to form a pulp deposited body on each split when the splits are separated from each other in a pulp slurry;
- closing the splits to join the pulp deposited bodies together to form a joined body of the pulp deposited bodies while the pulp deposited bodies are in the pulp slurry;
- and
- feeding a fluid into a pressing member in the joined body to press the joined body onto the inner surface of a mold, the cavity of which has a prescribed shape to make the joined body dry.
