The first pattern is composed of pattern elements each constituted by at least one of the first protrusions (10) and is comparatively well spaced apart mutually, while the second so-called background pattern comprises the second protrusions (2) arranged in more compact manner between the pattern elements. The sheet of paper is characterized in that the pattern elements form a graphic pattern while being arrayed at a rate of at most 0.5 element/cm.sup.2 and the first protrusions (10) constituting them evince at their top a line-shaped surface with a width between 0.1-2 mm, the second protrusions (2) being arrayed at the rate of at least 30, and preferably 40, protrusions/cm.sup.2 and ensuring the essential functional features.

Abstract: The cellulose fiber (tissue) product of the invention, such as a handkerchief or napkin, is made by combining at least two tissue plies cut into a desired format and connected to one another along a peripheral zone, and is characterized in that the plies are adhesively bonded along the perhipheral zone in such a manner that they evince a minimum delamination strength of 1 g/cm, and the peripheral zone is less than 50% of the total product surface.

Abstract: An absorbent multi-layer sheet, with at least two layers each constituted of at least one embossed ply of creped absorbent paper having a specific surface weight between 10 and 40 g/m.sup.2 per ply, with an external surface forming the outer side of the multi-layer sheet and an inner surface, the inner surface of the first layer including first and second protrusions and the inner surface of the second layer including third protrusions nested between the-protrusions of the first layer, the two layers being bonded together by at least part of the protrusion tips of one layer adhesively joined to the other layer between two protrusions, is characterized in that the bonding is implemented by the first protrusions of the first layer, the second protrusions having a lesser height than the first ones and their tips being adhesive-free.

Abstract: A method for depositing an adhesive diluted in a solvent, such as water, onto a substrate, such as a paper sheet (13) illustratively of cellulose wadding, and supported on and moving with a rotary cylinder (9) using a deposition apparatus (20) comprising at least one adhesive reservoir (23) and one cylinder transferring the adhesive onto the substrate, characterized in that the cylinder (25') does not have surface asperities and comprises first zones (25a) and second zones (25b) such that the quantity of adhesive dragged by the cylinder (25') onto the second zones is greater than the quantity of adhesive dragged onto the first zones.

Abstract: A method for embossing a sheet of creped paper composed of at least one ply, whereby the sheet is engaged between two metallic cylinders fitted with protrusions and driven in rotation in a conventional manner and mesh with each other while having a play e1 between the tops of the protrusions of one cylinder and the opposite surface of the other cylinder, and a play e2 between the slopes of two adjacent protrusions wherein e1 and e2 are determined in the direction transverse to the direction of paper advance in such a manner that the ratio of e1/e2 is between 0.8 and 1.

Abstract: A paper sheet having several distinct layers comprised of at least two plies of paper glued together in discrete areas and characterized by having patterns which correspond to areas of reduced thickness on both outer surfaces of the plies of paper.

Abstract: The present invention is directed to an embossed ply suitable for use in a multi-ply, embossed paper. The embossed ply has bosses of two different depths wherein the bosses having a greater depth or the "big bosses" alternate with the more shallow bosses or "small bosses". When the embossed ply is used to form a multi-ply paper, the small bosses are arranged in a tip-to-tip relation with bosses in a second embossed ply, while the big bosses of the first ply are positioned to nest between the bosses of the second ply. Furthermore, a method and apparatus for manufacturing the embossed, multi-ply paper is described.

Abstract: A method for printing and embossing sheets of paper made of cellulose wadding and with two or more plies, characterized in that one of the plies is directly printed on the embossing roller using one or more printing systems mounted on the embossing systems, and in that this ply is associated with another embossed and glue-sized ply to form a sheet in such manner that the print inks are located on the sheet's inner side between the two or more plies.

Abstract: A combined sheet material including at least two absorbent sheets, such as of cellulose-cotton, each having a density of between from 10 to 40 g/m.sup.2. Each of the sheets is separately embossed by calendaring them into a pattern of protuberances distributed in a first pitch along a first direction for each sheet (P.sub.1 sm, P.sub.2 sm) and in a second pitch in a second direction for each sheet (P.sub.1 st, P.sub.2 st) which subtends the first direction at an angle other than zero. The end of the protuberances extending away from the plane of each of the sheets includes a flat bonding element whereby the two sheets are bonded to each other, preferably by gluing. The pattern of each of the sheets is characterized in that the first pitch of each sheet along the first direction is different and related by the equation..vertline.1/P.sub.1 sm-1/P.sub.2 sm.vertline..gtoreq.

Abstract: The procedure consists in compressing locally the fiber padding by means of a specifically profile tool, and in placing the powdery product in the impression left by the tool. According to an additional characteristic of the procedure, a compression force is then applied on the product in order to set it in the fibrous mass.A device for the operation of the procedure is made of two cylinders (20, 30) connected by a belt (40). The teeth of the first cylinder (23) fashion the impressions; the perforations (41) of the belt permit the localization of the powder in the impressions, and the teeth of the second cylinder (33) enable its setting.The procedure concerns especially the incorporation of superabsorbent material in the fiber padding of disposable hygiene articles.

Abstract: The invention relates to a self-attaching fastener of the buckles and grips type supplied notably as fastening means (2,3) in disposable articles (1). It relates in particular to a buckles part (3), of open structure fabric.In order to be able to fix by means of a cold adhesive glue this part to a support such as a sheet of plastic material constituting the external face of a complete diaper, the invention proposes to associate the element to a film of synthetic resin on at least part of its surface not provided with buckles.In a particular mode of embodiment, the film acts as linking layer for an additional layer consolidating the part.

Abstract: The absorbent laminated sheet is composed of at least two plies (1.9), embossed, constituted essentially of cellulose fibers, bonded together at least partially by means of protruding elements relative to the surface of said plies and pointing inward to the sheet; it is characterized in that the protruding elements (101) are positioned essentially according to lines or combinations of lines reproducing spaced motifs (100), which recur indefinitely.Application as domestic or sanitary paper.

Abstract: An absorbent structure for disposable articles, comprising between a permeable sheet (1) and an impermeable sheet (7), a pad comprising successively at least one fibre layer (2, 12, 22, 32), an internal reinforcement sheet permeable to liquids and an absorbent layer provided with improved retention additive particles is characterized in that the internal reinforcement (3, 13, 23, 33) is a non-woven material maintained by gluing (4, 14, 24, 34) to said absorbent layer (5-6, 15-16, 25, 35-36).

Abstract: This invention involves a device forming a sanitary napkin.The device includes a preformed, usually biconcave fluid-absorbent pad component (2) defining a biconcave central area (8) of reduced width, entirely arranged inside a covering (10) which is permeable to said fluids, and a layer (16) made of a component impermeable to fluids which is inserted between the pad component (2) and said covering (10), characterized in that said covering (10) is designed with a width (L) larger than width (l) of said pad component (2) at the level of said biconcave reduced-width area (8), thus defining side wings or flaps (20, 22) that are sealed together.This device improves lateral tightness while providing excellent comfort.
