In designing web-handling machinery for papers, steel sheets, endless belts, etc., the line management of strips is one of the most important technologies. Since these strips are very thin, they easily walk in the lateral direction when running on rolls, due to the roll misalignment, thickness imperfection and/or heterogeneity of strips and some other reasons. For a narrow strip with an infinitely long span, some researchers have succeeded in analyzing the lateral walking, taking account of the misalignment of a roll. However, for a wide strip with a short span, the infinite boundary conditions for the strip is no longer valid, because the deflections of adjacent rolls strongly affect the deformation of the strip. In this paper, a new theoretical approach for analyzing the lateral walking phenomena of wide strips is proposed, where the deflection of all the adjacent rolls are considered. The effects of the roll misalignment, roll crown, the friction between rolls and a strip, as well as the line tension, to the lateral walking are discussed.
