Abstract: front page image
(EN) The invention relates to a method for manufacturing a molded article (10) from pulp (72), wherein the article (10) comprises at least one article body (12), the method comprising at least the steps of: - introducing pulp (72) into a mold (22), wherein the mold (22) comprises at least two movable mold parts (24, 26) which, in an assembled condition (A), form at least one cavity (28) for forming said article body (12); - opening the mold (22) and introducing at least one parison (36) into the mold (22); - closing the mold (22); and - expanding the parison (36) by means of a fluid thereby pressing the pulp (72) against inner walls of the mold (22) and creating from the parison (36) an inner protective layer (42) of the molded article (10), the inner walls bounding said cavity (28).
(FR) L'invention concerne un procédé de fabrication d'un article moulé (10) à partir de pulpe (72), l'article (10) comprenant au moins un corps d'article (12) et le procédé comprenant au moins les étapes consistant à : - introduire de la pulpe (72) dans un moule (22), le moule (22) comprenant au moins deux parties de moule mobiles (24, 26) qui, dans une condition assemblée (A), forment au moins une cavité (28) pour former ledit corps d'article (12); - ouvrir le moule (22) et introduire au moins une paraison (36) dans le moule (22); - fermer le moule (22); et - dilater la paraison (36) au moyen d'un fluide, pressant ainsi la pulpe (72) contre les parois internes du moule (22) et créant à partir de la paraison (36) une couche de protection interne (42) de l'article moulé (10), les parois internes délimitant ladite cavité (28).
