Abstract
A leveling technique that produces a high degree of flatness of strips and gives strips a characteristic such that parts cut from the strips by etching do not warp. Also, a method of leveling strips including the steps of rectifying a trip by tensioning and bending the strip with a tension leveler. The load acting on the strip by the tensioning and bending being 70% or more of the yield or proof stress of the strip. The method also including rectifying the strip by tensioning the strip with a roller leveler. The tension acting on the strip by the roller leveler being 50 N/mm.sup.2 or less.
