Abstract
An adjustable die set and method for forming corrugations in a sheet in which pairs of elongated forming bars are detachably mounted parallel to each other in respective holders driven by upper and lower press members. One pair is more closely spaced than the other and moves between the forming bars of the other pair to form a corrugation. The spacing and depth of the bar is varied to produce corresponding varying configurations of the corrugations.
