<P>PROBLEM TO BE SOLVED: To change the order by altering the position of corrugated cardboard according to correction data for correcting a measuring error and to successively manufacture a corrugated cardboard sheet having predetermined sheet length from the preceding corrugated cardboard cut at the order altering position. Ž<P>SOLUTION: When the first sheet rear end of an order 1 is decided to be cut (S10), the correction data matched with the operation conditions, that is, the feed speed, the paper quality of the corrugated cardboard and the kind of flutes, of the order 1 is read (S11) from among many correction data stored in a data memory 130 and the measuring error is calculated according to the correction data (S12). Since the correction data is the ratio α of the measuring error to a measuring feed length LX, the measuring error becomes a value calculated by multiplying the measuring feed length LX by the ratio α. Rear end tracking length is instructed to a rotary shear control unit 141 (S13). The rear end tracking length is the sum total length of the distance between a position P1 and the handredth sheet part rear end and the measuring error. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
