Abstract (en)
[origin: US4800047A] Trickling sheet (2) comprising in the direction of its first side or base (3) a first zone which is greatly corrugated (5) and a second zone which is slightly corrugated or flat (6), of equal width, these zones being provided with spacer bosses (7) at the two sides of the sheet, the mean plane of the second zone or the plane of the flat zone (6) being offset in such a manner that the tops of the bosses (7) of one of the two faces of the sheet are co-planar. An assembly of such sheets juxtaposed with one another by turning one sheet out of two through 180 DEG about the median line (9) separating the two zones constitutes a packing element with rectilinear channels, without obstacles or awkward recesses or bottlenecks.
