Abstract

A method of and an apparatus for forming finished cups of expanded resin of the present invention employ a transfer mold capable of transferring a performed article obtained through a preforming process to the female member of a finish-forming mold, and simultaneously collecting from the male member of the finish-forming mold a finished article, obtained through compression forming and discharging it after an inspection process, and enable a first process where the transfer mold receives a preformed article through a feeding device, a second process where the finished article is discharged from the transfer mold to a sorting device wherein conforming articles are counted and stacked, and a third process where another preformed article is heated and compressed within the finish-forming mold, to be conducted simultaneously. Further, a fourth process where the preformed article is transferred by the transfer mold to the female member of the finished-forming mold, and a fifth process where the finished article is transferred from the male member of the finish-forming mold to the transfer mold can be conducted simultaneously. Also, a sixth process where the conformity of the finished article is checked, and a seventh process where defective articles are removed and conforming articles are counted, are executed while the transfer mold is moving. The time required to perform all the processes is thus significantly reduced.
