Abstract
A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.
