Abstract: A sanitary towel having two side flaps designed to be folded around a folded sanitary towel after use to form a disposable package or small bag is described. The side flaps are preferably designed to form an integral part of a small protective pouch in which the sanitary towel is packaged prior to use. The invention obviates both the need for a separate package for disposal of the used sanitary towel and the use of independent individual packaging for the sanitary towels.

Abstract: An anti-theft dispenser of material wound in a core-free roll is provided. The dispenser includes a substantially planar support and a shaft to support the roll which is perpendicular to the support. The shaft is fitted at its free end with a stop and a compressible anti-extraction element in the shape of a helically extending blade angled relative to the axis of the shaft and having a blade edge and which is axially rotatable on the shaft and is mounted perpendicularly to the support to prevent extraction of the roll in a direction away from the support.

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: A disposable sanitary article for incontinent persons, with a substantially rectangular configuration.This article includes an absorbing pad 3, an impermeable external sheet 2, and a permeable inside sheet 4. The longitudinal edges (b, b') are folded back on the permeable inside surface. This configuration is kept in place at each end by a permanent fastening means, in particular a bead of adhesive 7, and provides a pouch effect in use.Use of this article for incontinent adult males with fastening to any kind of underwear.

Abstract: The invention relates to a method for forming a hydraulically bound web. A homogeneous mixture of wood pulp and synthetic fibers is blown on a forming surface. The web has a mixture of at least 70% wood pulp by weight of the mixture. The web is subjected to hydraulic bonding to form a stable fabric. The web is further heated to a temperature to cause partial melting of the synthetic fibers and further bonding of the fabric.

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: The invention concerns a method for making a non-woven from unbleached cotton or other natural ligno-cellulose fibers comprising a surface layer of substances rendering the fiber hydrophobic and comprising the following stages:formation of a sheet of unbound fibers on a water-permeable cloth,tangling the sheet fibers by means of a plurality of water jets issuing from arrays of injectors located transversely to the direction of advance of the support, the method being characterized in that the total energy imparted to the sheet by the set of jets is at least equal to a minimum threshold corresponding to the value at which said sheet becomes hydrophilic.The invention also concerns a hydrophilic non-woven made by hydraulic binding from unbleached cotton or other natural, ligno-cellulose fibers such as flax, hemp or ramie and free of chemical treatment.

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.
