ABSTRACT:
During the parallel splitting up of workpiece panels, in particular, consisting of laminated, compressed wood, it is usually not possible to prevent one of the two panel sections resulting after completion of the last separating cut, more particularly, that which was clamped in the feeding device, from warping on account of material tensions, thereby rendering it useless. In order to avoid this, it is proposed that the trimmed edge of the last remaining panel section facing away from the cutting plane be released prior to the final feeding procedure to be carried out, that it be clamped again immediately thereafter, that a further trimming cut be made on the panel section, and that this panel section then be fixed following the final feeding procedure and trimmed anew. In this process, the last resulting panel section is relieved of tension before being finally trimmed along its two longitudinal sides. This ensures that the trimmed edges subsequently produced thereon are exactly parallel to one another.
