Patent number: 8430660Abstract: 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.Type: GrantFiled: August 18, 2006Date of Patent: April 30, 2013Assignee: Dixie Consumer Products LLCInventors: Albert D.

Patent number: 8047834Abstract: A heated, segmented pressware die set for making pressware containers from a paperboard blank includes a plurality of guide keys mounted between at least one of an inner member of a punch or die and an outer ring which reciprocates independently. Each guide key extends in an outward direction from the central axis of the die set. The guide keys are positioned, configured and dimensioned to engage the outer ring in order to limit rotation of the outer ring with respect to the inner member of the punch or die. In a preferred construction, the guide keys have radially extending planar surfaces which cooperate with guide channels having like surfaces such that clearances necessary to accommodate thermal expansion are reduced, greatly increasing durability of the tool.Type: GrantFiled: April 28, 2009Date of Patent: November 1, 2011Assignee: Dixie Consumer Products LLCInventors: Mircea T. Sofronie, Albert D. Johns, Mark B. Littlejohn, Kenneth J. Zirbel, Luke G. Stumpf, Gary J. Reif

Patent number: 7229274Abstract: A tooling system in a press for forming a product from a blank of material disposed between a punch assembly and a die assembly and a method of using the same. The tooling system comprises a knockout and a bushing. The knockout further comprises a shaft having opposed ends, a plate fixed to one opposed end, and a tapered portion. The bushing is supported by one of the punch and die assemblies and defines a lumen configured to slidably receive the shaft for axial movement between an extended position and a retracted position. The lumen has a tapered receiving section at one end thereof configured to mate with the tapered portion of the knockout when the shaft is in the extended position.Type: GrantFiled: June 20, 2005Date of Patent: June 12, 2007Assignee: Dixie Consumer Products LLCInventors: Albert D.

Patent number: 7169346Abstract: In an apparatus for manufacturing pressware containers from container blanks there is provided a plurality of inertial blank stop pins disposed so as to position a container blank prior to press forming. The stop pins are rotatable in order to absorb the kinetic energy of the container blanks as they are fed to the apparatus and eliminate blank bounce. In a further aspect of the invention there is provided a method of forming plates utilizing the improved apparatus including the inertial blank stop pins.Type: GrantFiled: April 28, 2003Date of Patent: January 30, 2007Assignee: Dixie Consumer Products LLCInventors: Albert D.

Patent number: 7070729Abstract: An improved pressware die set includes mechanical ejectors for removing formed product from the punch. A preferred embodiment includes rocker-style ejectors free from edges or other asperities which may tend to snag and mar the product during the production process. Most preferably, the outward surfaces of the rocker members extend beyond the perimeter of a paperboard blank positioned for forming so the paperboard blank does not encounter an obstruent outward edge during forming.Type: GrantFiled: September 6, 2002Date of Patent: July 4, 2006Assignee: Fort James CorporationInventors: Albert D. Johns, Mark B. Littlejohn, Thomas W. Zelinski
