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.
