ABSTRACT:
A cutting instrument includes a base plate and a pair of cutting blades slidably mounted to the base with a slide block and rail system for cutting movement. A reference rod assembly is provided to maintain the internal flutes of a corrugated paper board in parallel relationship to the cutter blades during cutting to ensure first and second cut edges which are precisely parallel to the flutes. The reference rod assembly comprises two pairs of parallel reference rods which project in a common plane from a key stock plate. The distal ends of these rods, after respectively passing through flutes in the paper board to be cut, are adapted to be received in blind bores formed in a side surface of a guide rail to support the reference rods on the rail. The key stock plate further includes a pair of parallel positioning pins which are received in a pair of bores formed in a side edge of the base plate. The reference rods are thereby secured at their opposite ends to maintain the desired parallelism between the flutes and cutter blades during cutting. A method of precision cutting utilizing a reference rod clamping arrangement is also disclosed.
