    Abstract: A process for making a continuous web of a longitudinally corrugated fibrous material includes passing the web between a rigid cylinder having circumferential grooves that are flanked and shaped to define a substantially corrugated profile on substantially on the entire thickness of the web, and a presser which has an external layer made of an elastically compressible material and which is maintained adherent to the rigid cylinder so as to cause the continuous web to penetrate into the grooves and thus obtain the corrugations, At the same time, the continuous web is subjected to a reduction of the speed of the surface in contact with the presser with respect to the speed of the surface in contact with the rigid cylinder so as to have a longitudinally corrugated pattern on both surfaces and transverse ripples at least at the corrugated surface that was in contact with the rigid cylinder.

    Abstract: An apparatus for producing a web of fibrous material, characterised by comprising: includes a roll having incisions with a depth of 0.01-2.00 mm a width of 0.01-2.00 mm and a pitch 0.01-10.00 mm, and rotated at a peripheral velocity v1 equal to the velocity of an upstream apparatus unit; a belt stretched between transmission rollers that advances at a velocity v2 less than v1 where v1/v2 lies between 1.05 and 1.40; a presser roller rotating at a peripheral velocity v2, associated with a presser system acting to press the belt against said the metal roll with a pressure between 1 kg and 200 kg per centimeter; a system that feeds a sheet of pliable fibrous material between the belt and the roll, the belt elongating longitudinally no more than 5% dimensional stability along its entire length, and thickness between 1 cm and 10 cm, and hardness between 24° Shore and 70° Shore.

    Abstract: A method of producing a web of extensible fibrous material includes passing a web of fibrous material between a cylinder of rigid material having, on the side surface, a plurality of incisions running circumferentially, and a web having an outer layer of elastically compressible material kept locally pressed, at a pressing area, against the side surface of the cylinder, the cylinder and the web being configured and arranged so that the web adheres to the cylinder over a portion located downstream of the pressing area, the web has a portion downstream of the pressing area with a concavity substantially opposite to that of a portion of the web upstream of the pressing area, and the peripheral speeds of the cylinder and the web in the pressing area are substantially equal.
