Abstract
Improvements in the manufacture of covered corrugated cardboard consisting essentially of extending between two flat sheets of cardboard, materialcolor and appropriate dimensions, a third sheet of the same nature and bent in a zigzag with a rectilinear pattern whose aristasdotada of a practically nulling arose to the aforementioned external parts with the help of the corresponding adhesive, thus forming a broken triangular elevation bore and with extreme angles of variable value, requiring the structural alignments of true sinuosity or undulation in the main phases in the crushing of the cardboard in the presence of the loads whose phases determine the transformation of the triangular profile in another trapezoidal-reversible in the second of those phases and when the pressure is continued in another rectangular one that causes the parallelism of stops offers a maximum resistance to the required stress up to the single conditioned limit because of the nature of the material.
