1. A cutting apparatus for cutting of band shaped raw material, consisting essentially of:

  • at least two cutters having different cutting shapes located solely above the raw material, said cutters being in a side-by-side array with each one of said cutters being independently movable and having blade or cutting edges in a plane parallel to a feeding direction of said raw material and receiving portions directly below and axially aligned with a cutter and directly below the raw material;

    a stationary cutter guiding section including (1) a plurality of vertical guide slots, each one of the guide slots having a respective one of said cutters therein for guiding said cutters to perpendicularly move downwardly against a plane of said raw material, and (2) means for biasing said cutters upwardly;

    means including an element spaced above said cutters for applying force to perpendicularly move and press said cutters into said plane of the raw material;

    a cutter die for supporting said raw material against the pressing force of said cutters and simultaneously interacting with said cutters to execute a cutting pattern on the raw material;

    a plurality of hydraulic pressure members located lower than and to one side of said element, each one of said pressure members being selectively movable between said element and a respective one of said cutters for transferring the pressing force to the respective one of said cutters;

    driving means for selectively moving the pressure members beneath said element;

    a control section for controlling said driving means and each said receiving portion collecting cut raw material.
