A method and apparatus for cutting and scoring plastic and paper box blanks is disclosed wherein a creaseless score line is formed using a score forming strip which is aligned on one die platen and is transferred to the cooperating die platen in mirror image alignment.
Claims7
A method for cutting blanks from rigid and semi-rigid material and scoring the blanks to provide creaseless fold lines, comprising,
- providing a die face having knife edges protruding therefrom defining the general outline of a blank to be cut,
- providing an elongated generally thin flat score forming material having at least two closely spaced substantially parallel ridges protruding from one surface thereof,
- aligning and supporting said score forming material on said die face within the general outline defined by said knife edges and with said one surface and ridges of the score forming material facing said die face,
- aligning a flat platen with said die face,
- moving said die face and platen together thereby engaging said score forming material with said platen,
- transferring said score forming material onto said platen in mirror image alignment,
- separating said die face and platen,
- placing material to be cut and scored between the die face and platen, and
- moving said die face and platen together thereby penetrating said knife edges into one side of the material to be cut and scoring the opposite side thereof.

An apparatus for cutting blanks from rigid and semi-rigid material and scoring said blanks to provide creaseless fold lines, the apparatus comprising,
- a die face,
- knife edges positioned on the die face in the general outline of the blank to be cut,
- an elongated generally flat thin score forming material having opposite surfaces, and at least two closely spaced substantially parallel ridges protruding from one surface, the opposite surface adapted for having an adhesive applied thereto,
- coacting alignment means on said die face and score forming material, said alignment means being operative to position and support said score forming material on said die face within the general outline defined by said knife edges and with said one surface and ridges of the score forming material facing said die face, and
- a flat platen alignable with said die face whereby upon application of adhesive to the opposite surface of said score forming material and upon aligned movement of said die face toward said platen, said score forming material is transferred to and positioned on said platen for scoring a blank cut by the knife edges of said die face.
