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:
The rotating cylinder comprises: an elongated inner core (12) which is substantially rigid and an interchangeable sleeve (45) which is fitted onto the core; the sleeve is axially and angularly constrained to said core and is provided on its external surface with a raised pattern. The internal surface of the interchangeable sleeve and the external surface of the inner core are conical surfaces which are mutually complementary; axial and angular locking of the interchangeable sleeve and the inner core is achieved by the friction between the conical surfaces which are forced axially one onto the other.
Abstract:
Bei einem Papiertuch (1) mit z.B. drei Lagen (2, 3, 4) sind die zwei äusseren Lagen (3, 4) mit einer Prägung (6) und die innere Lage (2) mit einem Druck (5) versehen. Die Lagen (2, 3, 4) sind wenigstens teilweise transparent und mittels eines gefärbten Leimes als Bindemittel (9) miteinander verklebt.
Abstract:
The invention concerns composite materials and wiping articles exhibiting improved absorbent properties. More precisely, it concerns absorbent composite materials consisting of a superabsorbent product arranged between two or several cotton-wool-like cellulose facing webs. The invention also concerns a method and a device for preparing said products or wiping articles, and their uses in particular for wiping various liquids (water, oil, grease, biological fluids, mixtures etc.) in industry.
Abstract:
The embossing unit includes in combination: a first support for a first embossing roller and a second support for a first pressure roller, cooperating with the first embossing roller. The second support presents two seats to receive and support the first pressure roller in two different positions with respect to this support. The embossing unit also includes a third support for a second embossing roller. The third support can take at least two different operating positions. A fourth support is provided to support a second pressure roller suitable to cooperate with the second embossing roller and suitable to take at least an operating position and an idle position. Finally, there is provided a fifth support with a double seat to receive and support in two different positions alternatively a marrying roll or the second pressure roller.
Abstract:
The disclosure relates an apparatus and method for assembling at least two webs of tissue paper with or without marking of the webs. The apparatus and method utilize a multi-marrying roller configuration, which allows for assembling of the at least two webs of tissue paper by passing between the marrying roller and the second marrying roller. The apparatus and method make it possible to produce a conventional embossed product, or a smooth product without marking, having combined plies. In addition, the apparatus and method make it possible to easily move from one production mode to the other.
Abstract:
A method for producing an article made of a web material, comprising at least one ply, wherein a superabsorbent material in powder form is associated with said ply.
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:
A method of manufacturing a hygiene product, includes the steps of providing at least a first web (1) and a second web (2), pre-treating the first web and/or the second web, embossing the first web with a décor embossing pattern in a first décor embossing zone (38) having a décor embossing roll (34), and laminating together the first web and the second web in a lamination zone (30), the lamination zone being defined between the décor embossing roll and a lamination roll (36), wherein the décor embossing roll and the lamination roll have a generally-equal surface hardness.
