摘要： An apparatus for supporting a coil of strip material and for rotating it about its polar axis comprises two sets of rollers arranged in parallel side-by-side relation, each set of rollers being coaxial upon a shaft. One driven roller is provided to rotate the coil by frictional engagement therewith, the remaining said rollers being idlers whose peripheral speed is permitted to vary compared to that of the driven roller to accommodate local variations in the peripheral speed of the coil which may arise due to local variations in coil radius. The width of the coil contacting surface of each roller constitutes a minor portion only of the axial distance spanning the said surfaces of the two rollers axially most distant from each other.
