SYSTEM FOR FORMING PACKAGES FROM FILM MATERIAL

摘要

An apparatus for forming sealed pouches comprising: a rotatable base forming drum having an outer surface with a plurality of base tooling cavities in the outer surface; a base stock supply mechanism for feeding a base stock film of material along a base stock path, a portion of the base stock path extending along the outer surface of the base forming drum; a system for displacing the base stock film into the base tooling cavities to form a pocket of base stock film material within each base tooling cavity; a material feed mechanism for feeding at least one material into each pocket of the base stock film; a rotatable lid forming drum having an outer surface with a plurality of lid tooling cavities in the outer surface; a lid stock supply mechanism for feeding a lid stock film of material along a lid stock path, a portion of the lid stock path extending along the outer surface of the lid forming drum; a system for displacing the lid stock film into the lid tooling cavities to form a lid recess of lid stock film material within each lid tooling cavity; a material feed mechanism for feeding a material into each lid recess of the lid stock film; and mechanism bringing the base stock web and the lid stock web into contact under pressure. In one form, the material fed into the lid recesses is a hardenable material and cooling is used to cool the lid recesses.
