Definitions

  • the present invention relates to the field of absorbent papers for sanitary and domestic use, and relates to a multilayer sheet for products such as toilet paper, handkerchiefs, towels, or wiping cloths, as well as its manufacturing process
  • US Pat. No. 3,867,225 for example, describes a process for producing such a product consisting in embossing two sheets of cellulose wadding separately according to a pattern consisting of projections or protuberances at a rate of 2 to 30 per cm 2 , applying an adhesive substance on the top of part of these projections, to bring the two sheets together by the embossed faces, that is to say having the protuberances, by placing the protuberances of one between the protuberances of the other, and glue the vertices of one sheet with the recessed areas of the other sheet.
  • voids formed between the two sheets a structure is thus produced having an improved absorption capacity compared to absorbent sheets not thus transformed.
  • connection points In certain applications of the product obtained, where softness is an important criterion, it would be desirable to avoid the presence of too many connection points between the two sheets, since the total surface bound to it is proportional and this constitutes an important stiffness factor.
  • the gluing is carried out by deposition by means of a gluing cylinder, the number of connection points is equal to that of the protuberances of the sheet receiving the glue.
  • this patent proposes partial gluing by the use of a glue applicator cylinder whose surface is hollowed out with cells. Unfortunately, such a solution has proven to be impractical industrially because it leads to rapid fouling of the cylinders by agglomeration of material in the cells.
  • US Patent 4320162 describes a multilayer sheet structure consisting of two embossed sheets. Each sheet comprises a broad pattern of first relatively deep embossed protrusions, surrounded by a tighter pattern of second less deeply embossed protrusions. The two sheets are associated, according to a first example, by the vertices of the first protrusions, and, according to a second embodiment, by the vertices of the first projections for one sheet and the vertices of the second projections for the other sheet.
  • Such a structure in theory offers a greater internal void volume than in the arrangement presented in US Pat. No. 3,867,225 since the two sheets are joined by the top of the projections. However, it is less resistant to crushing; there is in fact a collapse of the projections already under a low bearing pressure.
  • the present invention provides a multilayer structure combining the advantages of the two methods mentioned above without presenting the disadvantages, as well as its manufacturing method.
  • the subject of the invention is a multilayer absorbent sheet with at least two layers each consisting of at least one embossed sheet of creped absorbent paper weighing between 10 and 40 gm 2 per sheet, with an external face forming the external face. of the multilayer sheet and an internal face, the internal face of the first layer comprising first and second protrusions, and the internal face of the second layer comprising third nested protuberances between the protuberances of the first layer, the two layers being linked together by at least part of the tops of the protuberances of a layer made integral by bonding to the other layer between two protuberances.
  • This multilayer sheet is characterized in that said connection is provided by the first protuberances of the first layer, said second protuberances having a lower height than the first and their top having received no adhesive substance.
  • a sheet is obtained whose rigidity is lower than that of a sheet comprising the same number of protuberances also nested, but where the latter are all of the same height.
  • the resistance to crushing is not penalized.
  • the glued area can vary from 0.1 to 20% depending on the application for which the product obtained is intended.
  • the height of the second protrusions is greater than 50% of the height of the first protrusions. Indeed, optimum resistance to crushing is obtained if the second protrusions are substantially at the same level as the surface of the adjacent layer.
  • the first protrusions are distributed in a spaced pattern, at least two second protrusions being arranged between two successive first protrusions.
  • the first protrusions will advantageously reproduce a drawing combining a plurality of lines pleasing to the eye, that of a flower for example.
  • These drawings will be surrounded by points formed by the second protrusions and each occupying a small area, the density of these points may be relatively high, up to 80 or 100 points per cm.
  • the height of the third protrusions is less than or equal to the height of the first protrusions. In order to ensure satisfactory crushing resistance, it is desirable that the height of these protuberances is at least half that of the first protuberances.
  • the vertices of the third protrusions form a bond, by gluing, with the first layer.
  • the present invention also relates to a method for manufacturing the multilayer sheet presented above.
  • the method for producing a multilayer sheet consisting of embossing a first sheet of paper, itself single or multiple, on a first cylinder having on its surface first and second raised elements, and a second sheet, which can also be simple or multiple, on a second cylinder comprising third elements in relief, to deposit glue on at least part of the tops of the protuberances produced on one of the sheets, to bring the two sheets together so that the protuberances of the first sheet overlap between the protrusions of the second sheet, and the glued tops adhere to the other sheet between two protrusions, is characterized in that the first elements have a height H, measured relative to the surface of the cylinder, greater than the height h of the second elements, the difference between the heights H and h being greater than 0.05 mm: Hh> 0.05 mm
  • the difference between said heights H and h is less than 50% of H, in particular for H between 1 and 2 mm, and in particular when the height of the elements is between 1.2 and 1.5 mm.
  • a multilayer sheet is thus obtained, the second protrusions of which will optimally fulfill their role as a strut and resistance to crushing.
  • the third elements in relief, on the second cylinder have a height H "less than or equal to the height H: H * ⁇ H
  • the second cylinder has fourth elements in relief, the height h 'of the fourth elements being less than the height H * of the third elements.
  • H and h ' are linked by the relation: 0.5 xH' ⁇ h ' ⁇ H'- 0.05.
  • an adhesive substance is applied to both the first and the third protrusions.
  • FIG. 1 represents an installation for implementing the method of the invention.
  • FIG. 2 represents the pattern of the elements in relief, according to one embodiment, appearing on the surface of an embossing cylinder.
  • FIG. 3 represents the pattern of the elements in relief on the other embossing cylinder cooperating with the cylinder of FIG. 2.
  • FIG. 4 represents, seen in partial section, the multilayer sheet obtained according to the method.
  • This installation comprises two embossing units, each consisting of an elastomer-coated cylinder, 1 and 3 respectively, cooperating with an engraved steel cylinder, 2 and 4 respectively.
  • the cylinders 2 and 4 are etched so as to present in relief elements or pins, regularly distributed both in the machine direction and in the cross direction.
  • a first sheet of cellulose wadding 5, crepe absorbent paper used as sanitary or domestic paper, such as toilet paper, handkerchief, towel, or wiping cloth, is driven from a reel not shown and guided around the cylinder 1; according to the embodiment shown, it is a double sheet.
  • the cylinder is pressed against the cylinder 2 by suitable means not shown so that the sheet, passing between them, is caused to deform and follow the relief of the engraving of the cylinder 2.
  • the sheet is then driven by the latter .
  • a sizing device 8 known per se, deposits with an applicator cylinder an adhesive substance 9 on the top of the elements in relief or protuberances of the sheet 5.
  • the cylinder 4 is placed at a slight distance from the cylinder 2 so that the sheet can detach from the surface of the cylinder 4. It comes into contact with the first sheet, over a portion of its travel where it is still applied against the surface of the cylinder 2.
  • the two cylinders are driven at synchronous and opposite speeds; they are locked in rotation relative to each other so that the protrusions of the sheet 6 are received between the protrusions of the sheet 5.
  • a cylinder 7, said matchmaker, with smooth surface, driven in rotation against the cylinder 2 ensures the union of the two sheets by pressing the sheet 6 through its recessed areas - between two adjacent protrusions - against the vertices provided with glue 9 of the protrusions of the sheet 5.
  • the multilayer sheet obtained is then cut into sheets of small width and roll up, of toilet paper for example.
  • the cylinder has first and second elements in relief of different heights.
  • An enlarged, partial and perspective view of the surface of the cylinder 2 is reproduced in FIG. 1.
  • the first relief elements 10, on which the first protrusions form the first sheet have a height H, and are distributed on the surface of the cylinder according to a regular pattern or not.
  • the reliefs are obtained by etching or by machining, the height is measured from the top of the element which is generally planar, to the bottom of the etching. If the elements are reported, we proceed in the same way by difference in heights, the reference being the vertex of the highest of the elements.
  • first elements can be of any shape. They are advantageously constituted so as to form the imprint of a linear design, for example that of a flower such as that shown in FIG. 2.
  • the first elements 10 are relatively distant from each other. This spacing will depend in particular on the surface occupied by the drawing on the sheet. For example, for a drawing falling within an area of 100 mm 2 , the distance between the first two elements will be 15 mm.
  • the height H is between 1 and 2 mm.
  • a particularly suitable value for the production of toilet paper from cellulose wadding weighing between 10 and 40 gm 2 is between 1.2 and 1.5 mm, for example 1.3 mm.
  • the depth of the embossing and the height of the resulting protrusions on the sheet will depend on the hardness of the coating of the cylinder 1 and the pressure it exerts on the cylinder 2.
  • second relief elements 12 Between these first elements, relatively distant from each other, are arranged second relief elements 12 whose height h is smaller. In practice, the height h is measured by difference with H.
  • the second elements in the structure of the multilayer sheet must fulfill, like the first elements, the function of strut, to contribute to the compressive strength and give volume; however, they must be sufficiently set back from them so that the sizing device applies the adhesive substance only to the tops of the first protuberances of the first sheet.
  • the height h of the second elements will be at least 0.05 mm less than H but preferably will remain greater than half of H: 0.5 x H ⁇ h ⁇ H- 0.05.
  • FIG. 2 shows a partial plan view of the distribution of the first and second elements on the surface of the cylinder 2.
  • the cylinder 4 is engraved according to a pattern in agreement with that of the cylinder 2 so that the protuberances of the second sheet come to overlap between the protuberances of the first sheet when the two sheets are assembled according to the method of Figure 1.
  • Figure 3 shows a partial top view of the pattern of the elements in relief 14 on the surface of the cylinder 4.
  • Their height H * is equal to or less than that of the first elements of the first sheet: H " ⁇ H.
  • H H " ⁇ H.
  • the protrusions would be crushed and brought to the height H at the passage in the interval between the matching cylinder 7 and the cylinder 2.
  • the elements in relief of the cylinder 4 have a distribution identical to that of the second elements 12 of the first cylinder, leaving unembossed zones 16 into which the first elements in relief 10 fit.
  • Figure 4 is a partial sectional view of the multilayer sheet 100 obtained.
  • the sheet 5 comprises first protrusions 51, and second protrusions 52 of slightly lower height obtained with the elements in relief 10 and 12 respectively. As can be seen according to the embodiment of the figure, the latter is greater than half of that of the protrusions 51.
  • the sheet 6 itself has protrusions 61, called third protrusions obtained with the elements in relief 14. According to the embodiment shown, they have substantially the same height as the first protrusions 51, and, outside the areas occupied by the first protrusions, they overlap between the second protrusions 52 of the sheet.
  • the sheet 5 is linked to the sheet 6, between two protrusions 61, by the top of the protrusions 51 by means of a layer of adhesive 9.
  • the second cylinder comprises third and fourth raised elements which after embossing the second sheet produce third and fourth protrusions on the surface of the latter.
  • the heights H 'and h' of said elements in relief will preferably be linked by the same relationship as H and h, namely: 0.5 x H * ⁇ h ' ⁇ H- 0.05.
  • the two steel cylinders are arranged so that they mesh with one another. Compared to the solution of Figure 1, this guarantees correct positioning of the protrusions of the sheet 6 - that which is carried by the cylinder with which the matching cylinder is not associated - with respect to the protuberances of the other sheet. Indeed, by the meshing of the cylinders the two sheets are guided towards each other until they are assembled.
  • This arrangement is of particular interest when a glueer is provided on each of the embossing groups. The bringing together of the steel cylinders so that they mesh one inside the other already allows at this level a certain association of the folds. This arrangement, thanks to the second glue, is useful if one wishes to increase the number of connection points between the two layers.
