A die system ( ) for cutting a piece of sheet stock ( ) to create a blank and forming the blank to create a container includes first and second mating die halves ( ) and a cutting punch ( ). The first and second mating die halves ( ) are configured to move together to form the container from the blank. The cutting punch ( ) extends about the first die half ( ) and is movable therewith. The cutting punch ( ) is configured to cut the piece of sheet stock ( ) to create the blank. Movement of the die halves ( ) together causes the cutting punch ( ) to cut the blank from the piece of sheet stock ( ) and further movement of the die halves ( ) together causes the first and second die halves ( ) to form the container from the blank.

Pressed paper cut-in-place die

An improved apparatus and method as provided for releasing sheet material press-formed in a die assembly between mating male and female dies from the die assembly. A first air supply system is provided for injecting air between the male die and sheet material in the die assembly to break any vacuum existing between the male die and the sheet material. Subsequently, a second air supply system is provided for injecting air between the female die and sheet material in the die assembly during ejection of a press-formed article from the female die so as to break any vacuum existing therebetween. A system is provided for discharging excess trim waste severed from the press-formed article and routing the trim waste toward a scrap collector while permitting the article to be routed in another direction toward an article collector.

Apparatus for releasing a press-formed article from a die set

An apparatus and method is provided for simultaneously forming at least two interconnected deep-drawn containers in a single sheet of paper stock or the like. The apparatus includes a female die assembly formed to include a material-receiving cavity situated between spaced-apart first and second container-forming cavities. A blade assembly pushes a portion of the single sheet downwardly into the material-receiving cavity to provide a source of excess paperboard material from which the paper for adjacent containers can be drawn. A male die assembly moves to engage the female die assembly and draw at least the excess paperboard material deposited in the material-receiving cavity to form containers in the first and second container-forming cavities. A draw ring holds the sheet against the female die assembly during operation of the male die assembly. The apparatus and method are usable to simultaneously draw a pair of containers joined together by a hinged section so that one container can be folded about an axis over the other container to provide a clamshell container assembly.
