<p>The invention relates to packing formed by a stack of plates comprising corrugations forming a succession of positive and negative ridges. Each ridge includes wings and each wing is formed by at least one band cut into one of the plates so that it remains solidly connected to the plate at at least one side, said band being deformed to create a hole that breaks the continuity of the surface of the plate. According to the invention, the direction of the ridges of one plate forms a non-zero angle in relation to the direction of the ridges of an adjacent plate. Each plate comprises at least one longitudinal zone parallel to one of the edges of the plate and the ridges in said zone do not include a hole, said zones being positioned such that the zones of two adjacent plates are disposed on top of one another to form at least one contact point between a positive ridge and a negative ridge of two adjacent plates.</p> |
