ABSTRACT:
An improved pressware die set includes mechanical ejectors for removing formed product from the punch. A preferred embodiment includes rocker-style ejectors free from edges or other asperities which may tend to snag and mar the product during the production process. Most preferably, the outward surfaces of the rocker members extend beyond the perimeter of a paperboard blank positioned for forming so the paperboard blank does not encounter an obstruent outward edge during forming.
