Method for checking at least one cut edge of at least one material plate， edge checking device and system for cutting an endless plate strand to length

A method for checking at least one cut edge (38， 50) of at least one material plate (14) which is conveyed in a conveying direction (24) by a conveying device (20)， an edge checking device (18) and a system (10) for cutting an endless plate strand (12) to material plates (14). In the method， the at least one cut edge (38， 50) is optically scanned with at least one edge checking device (18). State information (46， 48) about the spatial state of the material plate (14) is obtained from the optical scanning. An orientation (46， 48) of the at least one cutting edge (38， 50) relative to at least one reference line (40， 42) is determined from the optical scanning. If the orientation (46， 48) of the at least one cutting edge (38， 50) relative to the at least one reference line (40， 42) deviates from a target orientation， at least one error message is generated.
