Multi-die cut with common axis

1. A die assembly comprising:

a first die having an outer surface, wherein the first die comprises:

a first blade having an edge defining a first shape for patterning a sheet of material;

a first foam layer surrounding the first blade; and

a first support for holding the first blade in position and supporting the first foam layer;

wherein the first die has a first perimeter;

wherein the first foam layer extends around the first perimeter of the first die; wherein the first foam layer comprises foam material which is reversibly deformable between an uncompressed state and a compressed state;

wherein the first foam layer comprises a planar top surface having a height which meets or exceeds the height of the first blade when the first foam layer is in an uncompressed state;

a second die having an outer surface, wherein the second die comprises:

a second blade defining a second shape for patterning a sheet of material;

a second foam layer surrounding the second blade; and

a second support for holding the second blade in position and supporting the second foam layer;

wherein the second die has a second perimeter; further wherein the second perimeter of the second die is greater than the first perimeter of the first die; wherein the second foam layer extends around the second perimeter of the second die;

wherein, the second support is independent from the first support; further wherein the second support does not provide support to the first blade; wherein the second foam layer comprises foam material which is reversibly deformable between an uncompressed state and a compressed state; wherein the second foam layer comprises a planar top surface having a height which meets or exceeds the height of the second blade when the second foam layer is in an uncompressed state; and

a third die having an outer surface, wherein the third die comprises:

a third blade defining a third shape for patterning a sheet of material;

a third foam layer surrounding the third blade; and

a third support for holding the third blade in position and supporting the third foam layer;

wherein the third die has a third perimeter;

further wherein the third perimeter of the third die is greater than the second perimeter of the second die;

wherein the third foam layer extends around the third perimeter of the third die;

wherein, the third support is independent from the first support and the second support; further wherein the third support does not provide support to the first blade or the second blade; further wherein the second support does not provide support to the third blade; wherein the third foam layer comprises foam material which is reversibly deformable between an uncompressed state and a compressed state; wherein the third foam layer comprises a planar top surface having a height which meets or exceeds the height of the third blade when the third foam layer is in an uncompressed state;

wherein the first blade, the second blade and the third blade are arranged to make three separate, simultaneous cuts to a given sheet of material.

2. The die assembly of claim 1 , wherein the first blade is secured within a first channel formed in the first support.

3. The die assembly of claim 2 , wherein the second blade is secured within a second channel formed in the second support.

4. The die assembly of claim 3 , wherein the third blade is secured within a third channel formed in the third support.

5. The die assembly of claim 4 , wherein the first shape of the first blade comprises five sides extending and centered around a central point.

6. The die assembly of claim 5 , wherein the second shape of the second blade comprises five sides extending and centered around the central point.

7. The die assembly of claim 6 , wherein the third shape of the third blade comprises five sides extending and centered around the central point.
