    Abstract: A paper web of the present invention has a longitudinal centerline and a transverse centerline, and comprises a plurality of first regions and a plurality of second regions. The first regions form boundaries separating the second regions, the first regions being substantially in a plane of the paper web. The second regions comprise a plurality of raised out-of-said-plane rib-like elements, the rib-like elements of each second region being disposed parallel to a major rib axis and perpendicular to a minor rib axis. All or most of each first regions have both major rib axis and minor rib axis components. The first and second regions undergo geometric deformation when the web material is subjected to an applied elongation along at least one axis. A method of the present invention comprises the steps of providing a cellulosic substrate; providing a first platen comprising toothed regions and untoothed regions; providing a second platen comprising toothed regions, the second platen being aligned with the first platen such that the toothed regions of the first and second platens mesh when operably engaged; and pressing the cellulosic substrate between the first platen and the second platen such that the toothed regions deform said web to form regions of discrete fan-folded rib-like elements. Optionally, the cellulosic substrate can be moistened prior to the pressing step.

    Abstract: The invention relates to a method for producing a structured voluminous non-woven fabric, comprising the following steps: producing a spunbonded non-woven fabric consisting of a plurality of monofilaments which are stretched only at 50 to 70% of the maximum possible stretch range to form a fiber skein and subsequent processing the raw non-woven fabric by means of a second pair of rollers (10a, b) with a metal outer jacket to improve the velvet finish. In the second pair of rollers, the positive elements of the positive roller are nops (11) arranged in rows and the surface of the negative roller has lamellas (13) which are arranged in an axial direction and provided with intermediate recesses (14) so that when the rollers roll against each other the lamellas engage in the channels left open by the nops.

    Abstract: A method for impression microengravings, which reproduce holograms, kinetic holograms, or diffraction patterns, directly on paper through an embossing process. Paper is subjected to a humidification step to give it a degree of humidity between 60 and 80% of relative humidity. The humidified paper is then passed through an embossing group, consisting of an embossing cylinder carrying the microengravings and a counterthrust cylinder, at a temperature and a pressure on the paper within the ranges of 90-220.degree. C. and 20-120 kg/mm.sup.2, respectively.
