Abstract
Abstract A packaged coil of steel strip material is provided by wrapping a stiff protective material around the outer circumference of the coil to provide overhanging projections of protective material at each end of the coil and then deforming the projections radially inwardly to overlie the end faces. The wrapping material is corrugated along its longitudinal edges to facilitate its radially inward deformation by passing it through cooperating pairs of toothed crimping wheels prior to wrapping it around the coil. The radially inward deformation of the corrugated edges of the wrapping material is carried out by fluted pressure rollers acting at the end faces of the coil.
