ABSTRACT:
A steel rule die assembly for cutting a fixed pattern in each of a plurality of stacked compressible material layers according to the shape of the steel rule including a plate member defining a support surface, a steel rule die adapted to be positioned on the support surface, and a continuous rigid frame adapted to be removably positioned on the support surface in surrounding relation to the steel rule die and pivotally secured to the plate member along one side edge of the frame so as to allow the frame to be pivoted upwardly about that side edge to allow removable and replacement of the steel rule die. Resilient sealing means are provided along the undersurface of the frame to form a continuous annular resilient seal on the bottom of the frame for sealing coaction with the plate member, airimpervious cover means are provided for covering the die and frame to define a vacuum chamber, and means are provided to exhaust air from the vacuum chamber to press the frame downwardly to sealingly compress the resilient sealing means against the plate member and compress and reduce the thickness of the stack layers prior to cutting of the layers with the steel rule.
