Definitions

  • the invention relates to a sheet of paper, in particular an absorbent paper sheet of creped cellulose wadding, comprising an embossing pattern.
  • the invention particularly relates to a sheet of paper, composed of at least a first and a second ply of creped cellulose wadding, intended for the field of wiping in household, domestic or industrial use, that is to say may be used as a paper towel, cloth etc.
  • embossing gives bouffant to the sheet and it induces an improvement in the absorption of liquids, touch and softness. It has been sought to further increase the absorption capacity by creating multilayer sheets obtained by combining at least two layers, also called folds, each consisting of at least one of said embossed sheets.
  • the former is known in the field as "nested" or interlocking. It consists first of embossing each of the plies separately so as to form on the surface protrusions generally substantially frustoconical or truncated pyramid. Then we put glue on the top protuberances of one of the folds, and the folds are arranged so that the faces having the protuberances come opposite, the protuberances of one between the protuberances of the other. The folds are finally assembled so that the protuberances having been glued together fit between the protuberances of the other fold.
  • the two plies are linked by glue points between the tops of the protuberances of a fold and unembossed areas between the protuberances of the other fold.
  • a structure is produced whose voids thus formed are suitable for ensuring the sheet an improved absorption.
  • the outer faces have a smooth and soft feel due to the recessed areas formed by the back of the protuberances. This technique is illustrated by US-A-3,867,225 and US-A-5,830,558.
  • the second method of assembly is known in the field under the designation "tips / tips". It differs from the previous one by the relative disposition of the two folds. These, after they have been embossed separately, are brought one on the other so as to coincide the tops of the protuberances, or at least part of these vertices. The folds are linked together by the tops of the protuberances, tips against points. This technique is illustrated by US-A-3,414,459 and EP-A-0,564,319.
  • the protuberances obtained during embossing are most often made to be distributed in a pattern in which the protuberances are generally aligned in a manner. or more directions, evenly. Such a pattern makes it possible to obtain a sheet which is homogeneous as regards its mechanical characteristics.
  • the flexibility of the leaf can be defined as its ability to deform in a regular fashion when it is placed in a user's hand, his fingers being stretched in line with his palm and the user then folding his fingers. .
  • a sheet of paper that has a high flexibility will then deform and bend or arch so as to remain substantially parallel to the shape determined by the inside of the palm of the hand of the user.
  • a sheet of paper that has low flexibility will bend along one or more lines, each portion of the sheet extending between two fold lines remaining substantially flat.
  • a sheet of paper with high flexibility is more enjoyable to use.
  • the increase in the flexibility of the sheet notably causes a decrease in its mechanical characteristics.
  • the object of the invention is to propose a new embossed paper sheet design which makes it possible to increase the flexibility of the sheet without diminishing its mechanical characteristics.
  • the invention proposes an embossed sheet composed of at least a first and a second ply of creped cellulose wadding of grammage between 12 and 30 g / m 2 of the type of which at least a first ply comprises a first embossing pattern consisting of a first series of first protuberances, of generally frustoconical shape projecting on the inner face of the first fold, which form in particular first alignments and whose vertices are linked to the internal face of the second ply vis-à-vis, characterized in that these two plies each comprise a second embossing pattern consisting of a second series of second protuberances projecting on the inner face the corresponding fold, and in that the vertices of the second protuberances of a fold extend opposite and close to vertices of the second protuberances of the other fold.
  • the invention also proposes a pair of engraved rolls for embossing an embossed sheet according to any one of the preceding claims, at least one of whose cylinders comprises a first series of first shaped spikes.
  • first series of first shaped spikes generally frustoconical and forming first alignments, characterized in that the two engraved cylinders each comprise a second series of second raised pins, point and / or linear vertices, each second pin of a cylinder corresponds substantially with a second pin of the another cylinder and whose sum of the heights of the corresponding second pins is substantially equal to the height of the first pins.
  • the invention finally proposes a method of manufacturing an embossed sheet by means of a pair of rolls according to the preceding claim, characterized in that it consists in embossing the two folds so as to form the first and second patterns of embossing, then to assemble the two folds so that the tops of the first protuberances are linked to the inner face of the fold vis-à-vis and the tops of the second protuberances of a fold extend vis-à-vis and near the vertices of the second protuberances of the other fold.
  • FIGS. 1 and 2 show an exemplary embodiment of a sheet 10 of embossed paper, in particular a sheet of paper consisting of a first upper ply 12 and a second lower ply 14 of absorbent paper, made of cellulose wadding crepe, intended for any type of hygiene or household products.
  • the cellulose wadding of grammage between 12 and 30 g / m 2 , is of the type obtained by conventional wet pressing, called "CWP", or of the type obtained by through-air drying, called "TAD".
  • the paper sheet 10 shown in Figures 1 and 2 is for example intended to be incorporated in a roll of paper towels.
  • the sheet 10 is oriented in two longitudinal and transverse directions, represented in FIG. 2 by the arrows L and T, which correspond to the direction of travel of the sheet 10 during its manufacture, also called the “Run” direction and to the direction perpendicular respectively, also called sense "Travers”.
  • a first pattern 16 is visible and visually detaches from the first 12 and the second fold 14 of the sheet 10.
  • the first embossing pattern 16 of each fold 12 and 14, of known general design, consists of first series of first protuberances 18 and 20 of generally frustoconical shape projecting on the inner face 22, 24 of the fold 12, 14 corresponding thereby extending towards the inside of the sheet 10.
  • the first protuberances 18 and 20 form in particular first alignments according to figures, in particular in closed loops which are here circles.
  • associated series of the first protuberances 18, 20 of the one and the other fold 12, 14 are nested, concentrically, between the associated series of the protuberances 20, 18 of the other 14, 12 of the two folds.
  • the first series of first protuberances 18 and 20 are aligned in two main directions so as to define a grid.
  • the two main directions here are perpendicular to each other, and are inclined at 45 degrees with respect to the longitudinal L and transverse directions T of the sheet 10.
  • the peaks 32, 34 of the first protuberances 18, 20 are connected to the inner face 24, 22 of the fold 14, 12 vis-à-vis (see Figure 2).
  • the first protuberances 18, 20 constituting the elements of the first pattern 16 are obtained by embossing the first 12 and second plies 14 of the sheet 10 by means of a pair of rolls, one of which 26 is shown in Figures 6 and 7.
  • the embossing roll 26 has on its convex cylindrical face 28 a first homologous series of embossed pins 30 of generally frustoconical relief shape, which are distributed in concentric circles according to the first alignments of the first protuberances 18, so as to produce the corresponding portion of the first pattern 16 of the first fold 12.
  • first protuberances 20 on the second ply 14 of the sheet 10 is produced by another similar embossing cylinder whose frustoconical raised peaks are distributed in concentric circles according to the first alignments of the first protuberances 20, so as to make the corresponding part of the first pattern 16 of the second fold 14.
  • first 12 and the second plies 14 are embossed, they are assembled together by bonding the vertices 32 or 34 of the first protuberances 18 or 20 on the inner face 24 or 22 of the second 14 or the first ply 12 vis-à- screw.
  • the two plies 12, 14 comprise a second embossing pattern 36 consisting of second series of second layers.
  • protuberances 38, 40 which are for example of generally frustoconical shape, that is to say at point vertices, projecting on the inner face 22, 24 of the fold 12, 14 corresponding, thus extending towards the inside of the sheet 10.
  • the axes A1 and A2 of the second protuberances 38 and 40 of the first 12 and second plies 14 are substantially aligned.
  • the second protuberances 38 and 40 are made similarly to the first protuberances 18 and 20, in particular by a second series of second frustoconical studs 46 which extend to the convex surface 28 of the embossing cylinder 26.
  • Each second pin of a cylinder preferably corresponds with a corresponding second pin of the other cylinder, and the sum of the heights of the corresponding second pins is substantially equal to the height of the first pins.
  • the second protuberances 38, 40 form in particular second alignments according to figures, in particular in closed loops, which are arranged between the first series of first protuberances 18 and 20.
  • the closed loops have the general shape of a square whose edges are curved and concave substantially parallel to the circles defined by the first protuberances 18 and 20.
  • the second alignments may consist of other shapes, geometric or not, such as diamonds or flowers.
  • the second alignments of the second protuberances 38 and 40 comprise circles which are arranged concentrically to the circles of the first series of first protuberances 18 and 20.
  • the second protuberances are not necessarily frustoconical protuberances with point peaks, but may also be of the type with linear vertices defining more or less complex linear patterns.
  • the second protuberances can also be combinations of point vertices and linear vertices on the same fold, on the two folds or respectively on one and the other of the two folds.
  • the second protuberances are frustoconical, they are preferably micro-protuberances, as compared with the first frustoconical protuberances, with a density of micro protuberances of between 30 and 80 protuberances per cm 2 .
  • the diameter of the peaks of the pins for etching the micro protuberances is for example of the order of 0.4 mm whereas that of the first (macro) protuberances is of the order of 1.0 mm.
  • the height of the first spikes 30 is equal to 1.3 millimeters while the height of the second spikes 46 is equal to 0.7 millimeters.

  • Such an embossed sheet has a greater flexibility than that of an embossed sheet made according to the state of the art while having mechanical characteristics and an absorption capacity which are not diminished.
  • the flexibility of the sheet 10 is improved because, during the bending of the sheet 10, the vertices 42 and 44 of the second protuberances 38 and 40 can move slightly one by relative to the other, that is, tilting and shifting in accordance with Figure 3.
  • the mutual support of the vertices 42 and 44 of the second protuberances 38 and 40 also makes it possible to minimize the crushing of the sheet 10, which enables the sheet 10 to retain its bulk, that is to say its absorption capacities. .
  • the vertices 42 and 44 of the second protuberances 38 and 40 may be in contact. They are not related to each other.
  • the vertices 42 and 44 of the second protuberances 38 and 40 are separated axially by a slight clearance J.
  • the two figures 2 and 4 represent second protuberances 38 and 40 which are symmetrical with respect to a median plane of the sheet 10, that is to say that their heights H1, H2 are equal as are the heights H1 ', H2 .
  • the second protuberances 38 and 40 may be asymmetrical.
