Abstract
Systems and methods for producing pressware are provided. In one or more embodiments, a method for producing pressware can include producing a pressware product between an upper forming die and a lower forming die contained within a forming die assembly, retracting at least a portion of the upper forming die from the pressware product, and ejecting the pressware product from the lower forming die while feeding a web material between the upper forming die and the lower forming die. The method can also include cutting a segment of the web material to produce a substrate, and pressing the substrate between the upper forming die and the lower forming die to produce another pressware product.
Claims19
A method for producing pressware, comprising:
- producing a pressware product between an upper forming die and a lower forming die contained within a forming die assembly;
- retracting at least a portion of the upper forming die from the pressware product;
- ejecting the pressware product laterally away from the lower forming die while feeding a web material between the upper forming die and the lower forming die, wherein the pressware product is ejected laterally away from the lower forming die and while disposed entirely below a plane of the web material being fed between the upper forming die and the lower forming die at the same time, wherein electing the pressware product further comprises moving at least a portion of the upper forming die and at least a portion of the lower forming die in opposite directions from one another;
- cutting a segment of the web material to produce a substrate;
- and
- pressing the substrate between the upper forming die and the lower forming die to produce another pressware product.
A method for producing pressware, comprising:
- producing a pressware product between an upper forming die and a lower forming die contained within a forming die assembly;
- retracting at least a portion of the upper forming die from the pressware product;
- electing the pressware product laterally away from the lower forming die while feeding a web material between the upper forming die and the lower forming die, wherein the pressware product is elected laterally away from the lower forming die and while disposed entirely below a plane of the web material being fed between the upper forming die and the lower forming die at the same time;
- cutting a segment of the web material to produce a substrate;
- and
- pressing the substrate between the upper forming die and the lower forming die to produce another pressware product, wherein the upper forming die and the lower forming die move in reciprocating and opposite directions perpendicular to the plane of the web material therebetween.
A method for producing pressware, comprising:
- pressing a substrate between an upper forming die and a lower forming die to produce a pressware product;
- moving at least a first portion of the upper forming die away from the lower forming die;
- moving at least a first portion of the lower forming die away from the upper forming die;
- ejecting the pressware product laterally away from the lower forming die while feeding a web material between the upper forming die and the lower forming die, wherein the pressware product is ejected laterally away from the lower forming die and entirely below a plane of the web material being fed between the upper forming die and the lower forming die at the same time;
- cutting a segment of the web material to produce another substrate;
- and
- pressing the produced substrate between the upper forming die and the lower forming die to produce another pressware product.
