ABSTRACT:
In the present invention, complete cutting is carried out by primary and secondary cutting devices without causing the crush, break or crack of a cut portion even in the case of a composite paper sheet such as a thick corrugated cardboard sheet or the like. There is provided a cutting apparatus for corrugated cardboard sheets which cuts and separates a corrugated cardboard sheet along the direction of travel and positioned upstream from a cylinder cutting portion. The cylinder cutting portion performs secondary cutting and consists of a knife cylinder having a knife and an anvil cylinder. The primary cutting device is provided with a cutter knife for performing primary cutting and is fixed to a bracket and is capable of movement and adjustment in the widthwise direction of the sheet. At the opposite side with respect to the corrugated cardboard sheet is provided a sheet guide capable of movement on a guide rod so as to change a relative position (gap) with respect to the cutter knife.
