Method for operating a board partitioning system for large-format boards and board partitioning system for large-format boards

A method of operating a panel-sizing system for large-format panels, in which a sawed joint is produced by the movement of a saw carriage along a cutting line, whereby during this movement, a scorer with a scoring blade first makes a scored groove in an underside of at least one panel, and during this movement a saw blade that is arranged, viewed in the direction of sawing, behind the scorer blade and located at least essentially in the plane of the scoring blade, produces the sawed joint, and during which the panel lies on a supporting table and is moved diagonally to the cutting line for successive sizing by a feed device, characterized in that the method comprises at least one of the following steps:

• a. making a joint in the panel by means of the saw blade, detecting the joint using an electronic detection device, storing the recorded data;
• b. moving the panel by means of the feed device by a prescribed feed distance;
• c. making a scored groove in the panel, said groove being parallel to the joint, by means of the scoring blade, detecting the scored groove using the same electronic detection device as in Step a;
• d. Comparing the position of the scored groove and the position of the joint in relation to a common reference that is fixed for the detection device;
• and
• e. correcting the position of at least one of the scoring blade and the sawing blade orthogonally to the blade plane, so that the center axes or the scored groove and the sawed joint lie approximately identically compared to the common reference that is fixed for the detection device.
