The number of straightening rollers between adjacent assemblies differs by , and the roller gaps of the straightening rollers between the adjacent assemblies are staggered. The purpose of "during the straightening process, when multiple pairs of straightening rollers are squeezed, multiple sections of rotating shafts may have small relative displacements. These displacements are eliminated and compensated by the couplings connecting the rotating shafts.
