  • Method and apparatus for forming scored lines on sheet material
    Patent number: 5220858
    Abstract: Apparatus and method for cutting partially through the layers of a laminate. The invention uses a roller having a resilient surface of specified hardness over which are stretched a number of wires extending helically about its circumference, so that the wires are supported on the tool surface by the resilient layer. A cooperating hard surfaced roller applies a controlled amount of pressure to the sheet material in a nip formed with the scoring roller. This arrangement provides highly even score lines.
