edge inspection device (18) for checking at least one cutting edge (38, 50) at least one material plate (14),which is transported by a conveyor (20) in a conveyor direction (24) through a border inspection area (18), with the edge inspection device (18) at least one optical detection device (30) for optical scanning of at least one edge (38, 50) and has at least one evaluation device (34) for the determination of the condition information (46, 48) on the spatial state of the material plate (14) from the optical scan, characterized by having at least one evaluation device (34) for the determination of an orientation (46, 48) of at least one Cutting edge (38,50) relative to at least one reference line (40, 42) from the optical scan and to check whether the orientation (46, 48) of at least one cut edge (38, 50) relative to at least one reference line (40, 42) deviates from a target orientation and to produce at least one error message if this is the case.
