    • A process for making a continuous web of a longitudinally corrugated fibrous material characterized in that a continuous web (24) of a non-corrugated fibrous material is passed between a rigid cylinder (18), which is affected on the side surface thereof by circumferential grooves which are flanked (22) and shaped so as to define a substantially corrugated profile reproducing the pattern of the corrugations (26) to be obtained substantially on the whole thickness of the web itself, and a presser (20, 30) comprising an external layer which is of an elastically compressible material and which is maintained adherent to said rigid cylinder (18) with a force suitable for making said continuous web (24) penetrate into said grooves (22) and thus obtaining said corrugations (26) affecting the whole thickness of the web itself, and at the same time said continuous web (24) is subjected, on at least one segment of the passage thereof between said rigid cylinder (18) and said presser (20, 30), to a reduction of the speed of the surface (25) thereof in contact with said presser (20, 30) with respect to the speed of the surface (23) thereof in contact with said rigid cylinder (18), said force for maintaining said presser (20, 30) adherent to said rigid cylinder (18) and said speed reduction between said two surfaces (23, 25) of the web (24) being mutually defined so that the web (24) exiting from said passage has: - a longitudinally corrugated pattern on both the surfaces (23, 25) thereof, - transverse ripples (27) at least at the corrugated surface (23) which was in contact with said rigid cylinder (18).
