    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: The invention relates to a process for realizing a re-closable container made of extensible paper, which comprises at least partly inserting a closing element (5) made of paper material (extensible paper) provided with a base wall (6) and a lateral wall (7), internally of a housing compartment (4) of the container. The lateral wall (7) of the closing element (5) is inserted and located at a portion of lateral wall of the container (1). A sealing layer (204) is coupled to the container in a position underlying the closing element (5). Also comprised is a contemporary deforming step of the lateral wall (7), the sealing layer (204) and the portion of wall of the container (1), such as to realize coupling/decoupling surfaces between the closing element (5) and the container (1).
