A method of aligning veneers during the manufacture of a wood panel, where an aligning table is provided in front of a press (20), where the veneers are stacked prior to being fed into the press. According to the present invention, it is taught how to ensure that the veneers are perpendicular to the conveying direction and how incipient angle errors are detected and corrected by means of a differential control of the press feed. According to the present invention, this is achieve by establishing a gap between two consecutive veneers at said intervals, whereupon the trailing edge of the leading one of said two veneers is detected by means of two photocells (11) arranged along a line perpendicular to the conveying direction and with a certain distance in the longitudinal direction of the veneers. A possible time difference between the signals emitted by the photocells (11) for detecting the trailing edge can then be used to change the conveying speed of the veneers on one side compared to the other side, until the time difference is eliminated.
