The subject of the invention is an improved method and installation for manufacturing corrugated cardboard. The abovementioned installation as shown in the figure comprises, in addition to the means constituting a machine suitable for manufacturing a "double-double" corrugated cardboard, a station 14 from which an additional sheet F3 is unrolled and guiding means, not shown, which make it possible to convey this sheet between the "single-face" upper cardboard F1C1 and the "single-face" lower cardboard F2C2, thus leading to a structure of two superposed "double faces" which are separated from each other at the station 21 in order to be conveyed to individual longitudinal and transverse cutting stations K1 and K2. <IMAGE>
