Abstract
Methods and apparatus for forming a score line with a reverse kiss cut in a deformable material are provided. A method can include providing two plates, such as a die plate with a scoring rule thereon and a counter plate with an aligned corresponding recess with a knife edge positioned therein and protruding toward the scoring rule. When the die plate is advanced toward the counter plate, the deformable material is forced into the recess of the counter plate to form the score line and the knife simultaneously forms a cut or slit in the bottom surface of the deformable material to form a reverse kiss cut.
Claims30
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.

- positioning the 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 deformable material into the recess and into engagement with the knife edge,
- whereby the scoring of the first face of the deformable material and the kiss cutting of the second face of the deformable material along the score line occurs substantially simultaneously, and
- wherein the kiss cut and score line are formed in a corner gusset of the deformable material.
