Latest Patents
Legrand's patent, titled "Flatness roller, system for measuring flatness and line for associated rolling operations," introduces an innovative flatness roller. This device features a body with at least one cavity that opens onto its outer surface through multiple slots. Two successive slots create a lamella, which is connected to the body by two connection portions. The flatness roller is equipped with at least one optical fiber that contains a strain sensor with a measurement axis. Each strain sensor is strategically housed in a cavity and attached at a connection portion of a lamella, with the measurement axis forming an angle of 20° or less with a plane orthogonal to the axis of revolution of the body. This configuration allows the strain sensor to send an optical response wave that accurately represents the strain according to its measurement axis.
