ELASTIC HONEYCOMB SHEET, ITS PRODUCTION PROCESS AND EQUIPMENT TO PRODUCE

摘要

An elastic folded honeycomb structure is described which is produced from a continuous web (10) of material by plastic deformation perpendicular to the plane of the material to thereby form half-hexagonal cell walls (5,7,15) which are essentially not flat and connecting areas (17,18). By folding in the direction of conveyance the cell walls meet to thereby form the honeycomb structure. The cell walls are formed from the 3D-structures such that the cells walls have convex and/or concave portions and exhibit an elastic behavior under flatwise compression.
