Patent ID: 7226405

Claim:
A method of forming at least one kiss cut and at least one score line in a sheet of deformable material, the method comprising: substantially simultaneously (a) scoring a first face of the sheet of deformable material, and (b) kiss cutting a second face of the sheet of deformable material along the score line, wherein the scoring of the first face of the sheet of deformable material and the kiss cutting of the second face of the sheet of deformable material respectively include providing a die plate having at least one protrusion for forming the score line in the sheet of deformable material, providing a counter plate having at least one recess for receiving a portion of the sheet of deformable material, the recess having at least one knife edge therein projecting toward the protrusion, positioning the sheet of deformable material between the die plate and the counter plate, and causing relative movement between the die plate and the counter plate such that the protrusion forces a portion of the sheet of deformable material into the recess and into engagement with the knife edge, whereby the scoring of the first face of the sheet of deformable material and the kiss cutting of the second face of the sheet of deformable material along the score line occurs substantially simultaneously.
