Abstract: A section of a foil is sandwiched between an upper die and a first lower die and heat deformed into a cavity of the first lower die while simultaneously synchronously displacing the upper die, the first lower die, and the foil downstream. Then the upper die is raised and recirculated back upstream while cooling the section of foil in the cavity of the first lower die and displacing the lower die with the section of the foil downstream. Another section of the foil is sandwiched between the upper die and a second lower die and heat deformed into a cavity of the second lower die while simultaneously synchronously displacing the upper die, the second lower die, and the foil downstream. The first lower die is disengaged from the foil in the downstream station and recirculated back upstream to the upstream station. These steps are then repeated.
