A wood fiber board (6) which is provided with a decorative layer (3) of paper or similar material, and where the length or width value of the decorative layer (3) deviates from its original value after it is applied to the wood fiber board (6), is cut into uniform panels using a board-dividing apparatus that compensates for these deviations. The board-dividing apparatus has a saw (1) that preferably has a plurality of saw blades (S1, S2,.. S n) which are adjustably spaced in parallel fashion. The board-dividing apparatus is equipped with a number of cameras and with controller which utilizes deviation measurement information to adjust the spacing of the saw blades. The wood fiber board (6) is first aligned with at least one initial camera (4a) at a point P1. Then, predetermined points (P1 and P2) in the decorative layer (3) are recorded by the first camera (4a) and a second camera (4b). A distance (L) between the points (P1 and P2) is determined, and thee discrepancy in the width or length value is determined by comparison of the actual position and the desired position of the points (P1 and P2). Then, the value of the determined discrepancy (A) is placed in relation to the number (n) of the saw blades (S n), and the parallel spacing (a) of the saw blades (S n) is modified by the value of the ratio of the discrepancy to the number of saw blades minus 1; (A/n-1). The orientation of the wood fiber board (6) to the saw (1) is displaced to one side in the amount of one half the determined discrepancy (A), and then the wood fiber board (6) is transported toward the saw (1) for cutting out the panels.
