Abstract
The present invention provides an improved pressware forming apparatus. At least one of die pairs used in the apparatus can be narrowed in a cross-direction as compared to the cross-directional width of pressware forming tools used in prior an apparatus. The present invention allows addition of at least one additional die pair in the pressware forming tool when used in a standard sized pressware forming apparatus. The present invention also provides components for use in such apparatus and methods of making pressware from the apparatus herein.
Claims20
An apparatus for forming a pressware product from a paperboard blank, comprising:
- at least two die assemblies, each die assembly comprising an upper punch portion and a lower die portion for forming a paperboard blank into a formed pressware product, wherein at least one die assembly has a cross-directional width that is less than 105% of a cross-directional width of the paperboard blank.
An apparatus for forming a pressware product from a paperboard blank, comprising:
- first and second die assemblies each comprising an upper punch portion and a lower die portion for forming a paperboard blank into a formed pressware product, wherein the first die assembly is positioned at a different elevation than the second die assembly.
A system for forming pressware products, comprising:
- a scoring station comprising a plurality of scoring rules and a plurality of score grooves arranged in a nested pattern that correspond to the scoring rules;
- a blanking station coupled to the scoring station and comprising a plurality of male cutting dies and a plurality of female recesses corresponding to the male cutting dies, the male cutting dies and the female recesses adapted to cut paperboard blanks from a web of material;
- a conveying system coupled to the blanking station and comprising a plurality of chute pairs adapted to transport the paperboard blanks;
- and
- an apparatus for forming a pressware product from a paperboard blank, comprising:
- at least two die assemblies, each die assembly comprising an upper punch portion and a lower die portion for forming a paperboard blank into a formed pressware product, wherein at least one die assembly has a cross-directional width that is less than 105% of a cross-directional width of the paperboard blank or wherein a first of the at least two die assemblies is positioned at a different elevation than a second of the at least two die assemblies, and wherein the apparatus is coupled to the conveying station and adapted to receive the paperboard blanks therefrom.
