ABSTRACT:
Method for molding articles from agglomerated particles utilizes a press and a plurality of molds mounted to circulate in a closed path. After the pressing step a mold is aligned at one end of a row of molds, the row is placed under pressure and the articles therewithin caused to set. Simultaneously a mold is withdrawn from the other end of the row. The latter mold is then emptied, and the emptied mold returned to the press. The aligned molds are fastened together during the setting step. The invention includes apparatus for carrying out this process.
