摘要： The present invention relates to a process and apparatus for forming a rolled or folded brim on a molded fiber pulp article and articles formed by such processes and apparatuses. The process includes steps of pre-treating the molded fiber pulp article with chemical solvent to temporarily reduce rigidity of a brim portion of the molded fiber pulp article, and rolling or folding a brim on the molded fiber pulp article. The apparatus for forming a rolled or folded brim on a molded fiber pulp article includes a moving mechanism having a pretreating station for pre-treating the molded fiber pulp article with chemical solvent to temporarily reduce rigidity of a brim portion of the molded fiber pulp article and a forming mechanism for rolling or folding a brim on the molded fiber pulp article. The process and apparatus can improve the strength, and rigidity of the molded fiber pulp article and reduce the weight thereof compared to such articles with flat rims.
