ABSTRACT:
An improvement in a corrugated strip having major flat sections which extend between longitudinal edges of the strip and which are joined along lateral edges by intermediate sections extending between the major flat sections, includes stiffening ribs protruding from the strip along at least one of the connected lateral edges of the major flat and intermediate sections, the stiffening ribs being oriented substantially perpendicularly to the lateral edges. Additionally, a method and apparatus for forming corrugated strips, including corrugated strips having stiffening ribs, includes structure for applying a force, through dies, to a strip of material along an axis which is oriented at an acute angle to the strip.
