Abstract
A method for inspecting a strip in a reversible rolling plant comprising at least one cage arranged between two winding/unwinding devices each having a mandrel. The rolling is performed in several passes until the requested thickness is obtained over the whole length of a useful part ranging between two service lengths maintained wound on each of the mandrels. According to the invention, at the end of the last pass between a winder/unwinder placed upstream of the cage in the rolling direction and acting as an uncoiler, and a downstream winder/unwinder acting as a coiler, the upstream service length is unwound completely from the uncoiler, then subjected to a roll pass; the strip is then cut in the vicinity of the end of its useful part to release, at its rear end in the direction of the last pass, an inspection length whereof at least one part corresponds to said upstream service length rolled once.
