Abstract

A multiply absorbent paper product consisting of three or four plies of absorbent paper, wherein the two outer plies (1, 2) are flat and the central ply or plies (3), placed between these two, are textured. A process for manufacturing said products involves the individual processing of each ply constituting the product.

Description

    Field of the Invention
  • The present invention relates to multiply absorbent paper products, and to the method for producing the same, for application in sanitary and household uses, more explicitly in sanitary papers, but as well in hand towels, towels, napkins, tissues and facials, that is, in the products called "tissue".
    • Background of the Invention
  • Domestic paper products, more particularly toilet papers, are currently made up of two, three or even four plies of paper. For example:
    • the patent US6746558B2 discloses a multiply product having a specific grammage and consisting of 3 layers or plies of paper, one outer and one lower, which are textured with predetermined protruding patterns, and a central ply, not textured. The process for producing said product comprises embossing a first outer ply in an embossing roll, overlapping a central ply at the protuberances of said first textured outer ply and embossing a second outer ply in an embossing roll. Then all the plies are joined, by nesting: the first textured outer ply, coupled with the central ply, is joined to the second textured outer ply through a marrying roll and applying sufficient pressure for this purpose.
    • the EP0564319A1 describes a product with 3 or 4 plies, all of which are textured. To obtain it, each ply is individually embossed, further occurring a first assembly of two plies and the resulting set is thereafter joined to another ply, also textured. If there are 4 plies in the overall product, the plies are joined two by two, and in the end, the two sets formed by two plies each are joined together to form the final product. There is a predetermined relationship between the embossing pattern of the different plies, regarding embossments and spacing, which will then support the process of joining the different plies.
    • in the patent US6733866B2 the product consists of 3 plies of paper, each of which is textured. The patterns of the different plies defined in the invention are such that the final set contains a random array of patterns. Regarding the process, each ply is embossed separately, and the plies are joined at the same time. There is also the possibility of first joining two plies (the upper and the middle), and then the whole of the latter joins with the third ply (the lower one in the final product).
    • in the patent EP2353859A1 the product consists of 3 plies, all of which are textured. The process of producing the described product consists in embossing one ply individually which is then joined with a central ply, and then this set is embossed a second time. The result set of plies is then joined to a third ply, previously and independently textured, in a marrying roll.
  • The present invention aims at creating an advance in the prior art by providing a solution for multiply absorbent products of superior quality in terms of surface smoothness, thickness and flexible robust structure, which are also manufactured through a manufacturing process which allows a reduction on the use of the embossing rolls, and a less pressure is needed to be applied, thus prolonging the working life of the equipment involved.
    • Brief Description of the Drawings
    • Figure 1 shows a cross-sectional view of a multiply product according to the definitions described in this invention.
    • Figure 2 shows the production process of the products described in this invention.
    Detailed Description of the Invention
  • The present invention concerns superior quality multiply absorbent products, through greater hand-feel, greater thickness and a more flexible robust structure. These characteristics are achieved by structuring three plies, two of these plies (upper (1) and lower (2)) being flat and the central ply (3) placed between the two, previously textured. Additionally, to this absorbent product it may also be added water or an aqueous solution containing softeners, essences, lotions, absorption promoters and / or strength improvers.
  • The manufacturing process described furthermore allows a reduction of the use of the embossing rolls coupled with a decrease on the amount of pressure needed to be applied, thus extending the working life of the equipment involved.
    • Example
  • In accordance with the preferred embodiment of the present invention, each ply constituting the product is processed individually. The upper ply (1) is kept flat while the central ply (3) in the product is pre-textured (4) prior to entering the embossing and winding process. These two plies are joined prior to their passage by an upper auxiliary steel roll (5), from which are then transferred to the laminating glue cliche roll (6).
  • In another preferred embodiment of the present invention, by the effect of a slight pressure between the laminating glue cliché roll (6) and the embossing upper roll (7) the upper ply may become textured.
  • The lower ply (2), which remains flat, is finally joined with the upper and central ply set in the last roll of the transformation process, the marrying roll (8).
  • The upper ply (9), whether it remains flat or textured in the final product, undergoes an additive addition process (10) prior to entering the embossing and winding process, with an aqueous solution characterized by the additives described above.
  • The central ply is subjected to an additive addition process (11) before entering the embossing and winding process with an aqueous solution characterized by the additives described above. In another preferred embodiment of the invention to this central ply only water (11) is added. These possibilities apply whether the upper ply in the final product remains flat or textured.
  • In another preferred embodiment of the invention, it is added an extra central ply (12), similar to the one mentioned above (3), in terms of additives and texturing, which is also attached to the upper ply (1) at the embossing and winding process.
