METHODS AND SYSTEMS FOR PRODUCING PRESSWARE

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.

METHODS AND SYSTEMS FOR PRODUCING PRESSWARE

A system for scoring a web of a roll of material comprises a plate, a scoring punch, a scoring station actuator, and a controller. The plate has a slot extending about a shape representing an outline of a pressware product. The scoring punch has a protruding blade operable to enter the slot of the plate. The scoring station actuator is configured to shift the scoring punch or the plate to press the blade against the web to form a slot in the web. The controller is configured to direct the scoring station actuator to press the blade to a first predetermined scoring depth within the web.
