Abstract:
A multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched regions of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking regions whose fiber orientation is biased along the direction between pileated regions interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.
Abstract:
Multi-ply fibrous structure products, more specifically embossed multi-ply fibrous structure products and methods for making same are provided.
Abstract:
The invention relates to an absorbent paper product, such as a napkin or tissue, including at least two tissue paper plies which are superposed and joined, cut or precut into a desired format and connected to one another at least over a segment of a peripheral zone. The plies are joined along the segment by marking patterns without resort to glueing and at least one ply is fitted with embossing patterns in a central zone. The invention applies to sanitary and household papers, in particular disposable napkins and tissues.
Abstract:
The device comprises an essentially rigid smooth first cylinder (1) and an essentially rigid second cylinder 83), the latter having points (3P), the first and second cylinders rotate in opposite directions about respective axes of rotation (1A, 3A) and are pressed against each other, thus defining between themselves a lamination nip (5), through which said at least two layers are passed. There is also a pressure roller 87), with a surface (7A) that is less rigid than the first and second cylinders (1, 3), this roller interacting with the second cylinder and being pressed against it. The pressure roller forms with the second cylinder (3) an embossing nip (9) through which the layers (V1, V2) previously laminated in the lamination nip (5) are passed and in which they are embossed.
Abstract:
A multi-layered paper product that has bridging regions for inhibiting nesting is provided. For example, the paper product can contain a first and second layer that define ridges and valleys. Bridging regions are formed into at least one of the outer surfaces of the layers. In particular, the bridging regions are positioned at an angle of between about 0null to about 180null relative to the ridges and also have a length sufficient to extend between the peaks of at least two of the ridges. The bridging regions can be formed in a variety of ways, such as with an embossing roll that contains embossing elements. Moreover, the bridging regions can also have a variety of shapes, sizes, orientations, and/or patterns.
Abstract:
The present invention relates to composite materials and to wiping items having enhanced absorbing properties. It more specifically deals with absorbing composite materials consisting of a super-absorbing product placed between two or several cellulose wadding webs. The invention also relates to a method and to a device for preparing these wiping products or items, as well as to their uses, notably for the industrial wiping of various liquids (water, oil, fats, biological fluids, mixtures, etc.)
Abstract:
The invention relates to a method for manufacturing a sheet of paper tissue which is embossed by an embossing cylinder of which the surface is fitted at least in part with embossing elements. The elements include a frustoconical base portion and a tip portion. The method is characterized in that the tip segment includes a flat of which the area is less than 75% of the smaller cross-sectional area of the base. Preferably the area of the flat is less than 20% of the base cross-sectional area. The invention furthermore concerns a sheet thusly manufactured and to sheets made of several plies of which at least one is a ply of the invention.
Abstract:
An embossing roll includes a roll body and a plurality of plates which are removably secured to the roll body. Each plate includes an outer surface which is provided with an embossing pattern. The plates can be secured to the roll body by vacuum and/or mechanical devices.
Abstract:
A device for ply-bonding tissue products comprising first conveying means for a first single/multi-ply tissue web; as well as a roll pairing (22, 30; 22, 28), one roll of which is an embossing roll (22; 28); and one of the two rolls (22; 28) has spikes (26) on the shell surface cooperating with a companion roll (30; 28; 22) of high rubber hardness. The two rolls are adapted in location and length of the spikes (26) so that the spikes perforate both the first tissue web (14) and the second tissue web (16) in the nip of the roll pairing.
Abstract:
The invention relates to a manufacturing method for an absorbent structure (10) having at least two plies (P1, P2) each constituted of at least one embossed sheet of creped absorbent paper, wherein the plies (P1, P2) engage between two engraved metal cylinders (CG1, CG2) fitted with protrusions (R1, R2), driven in synchronized rotation, and mutually nesting with a play (J) between the tops of the protrusions (R1, R2) of one metal cylinder (CG1, CG2) and the opposite trough surface (F2, F1) of the engraving of the other cylinder (CG2, CG1), the method being characterized in that the play (J) is less than the depth of the cylinder engravings and larger than the sum of the thicknesses (E1, E2) of the plies (P1, P2) which were previously shaped in such a matching manner that the plies (P1, P2) are not compressed when being engaged between the nested engraved cylinders (CG1, CG2).
