Definitions
- the present invention relates to the field of absorbent papers based on cellulose wadding, for sanitary or domestic use such as toilet paper, towels or any paper wiping, napkins ...
- cellulose wadding also known as tissue paper
- tissue paper is a low weight absorbent paper, between 10 and 45 g / m 2 , obtained wet from paper fibers. It includes, possibly, chemical additives in small proportions, according to the use for which it is intended. It can be obtained by pressing the still wet sheet on a heated cylindrical element of large diameter, on which it is dried and from which it is then detached by means of a metal blade applied against it, transversely to its direction of rotation. . This operation is intended to crepe the sheet which then has transverse corrugations to its direction walk. The crepe gives the sheet a certain elasticity at the same time as it increases its thickness and gives it tactile properties.
- Another known method of manufacture comprises a first step of drying the sheet, at least in part, by means of a stream of hot air therethrough. This can then be creped or not.
- the sheet thus manufactured is then transformed into another distinct phase of production known as transformation or conversion and associated with other sheets then called folds to form the final absorbent paper product.
- the association can be of a chemical nature by gluing, for example, or of a mechanical nature.
- the known methods consist in depositing a film of glue on all or part of the surface of one of the plies, and then in contacting the glued surface with the surface of at least one other ply.
- the combination of the folds can be performed by knurling or by compression, in the conversion or conversion phase.
- Knurling consists of compressing the folds to be associated between a wheel (or engraved wheel, provided with elements in relief) and a smooth cylindrical element.
- Each knurled band corresponds to the width of a wheel.
- the bands can form decorative strips on the sheet.
- association by knurling is limited when it is desired to make patterns across the width of a width. Indeed, even if a large number of knurls are arranged side by side (thus creating a large number of bands) there may be areas without knurling.
- EP 1 362 953 illustrates a particular example of an installation and method using knurling.
- the major difference with respect to the basic method described above is that the combination of folds takes place in wide parallel bands (machine running direction) on the sheet, and in that one applies an additive film such as oil on at least one side of the sheet.
- knurling generally creates problems of readability of the embossed pattern if it exists, because the knurling overwrites the embossing patterns.
- rollers In addition, in the case where a large number of rollers is used, adjusting and / or setting the rollers makes the manufacture difficult and complex.
- Embossing is also known which is a deformation in the thickness of the sheet or fold, which gives it a particular relief or hollow.
- the thickness of the sheet or fold is increased after embossing compared to its initial thickness.
- embossing adds thickness to each fold or sheet, it does, however, induce a substantial reduction in the breaking strength of the sheet. Indeed, the mechanical work on the fold (or the sheet) is accompanied by loosening interfiber bonds embossed areas.
- the embossing can be carried out individually on each ply, then the plies already embossed are combined by means of a marrying cylinder.
- the application WO 2004/065113 illustrates an example of this type of association.
- such a marrying cylinder is complex in particular when its entire outer surface must be covered with a hard material band wound helically.
- the two (or more) folds are embossed then associated by passing the sheet thus treated and formed, between an engraved cylinder and a marrying cylinder.
- the association can cause problems including wear of the engraved cylinder and / or the marrying cylinder.
- a first known approach is to cover the outer surface of the marrying cylinder, for example, a ferrule.
- the application FR 2 801 833 discloses a marrying cylinder (for example) on which is mounted a sleeve, a so-called securing layer being interposed between the cylinder and the sleeve.
- the bonding layer can be considered as an "elastic" underlayer that dampens the pressure variations and also the manufacturing differences of each of the cylinders.
- the present invention provides a solution which relates to a process for producing an absorbent sheet comprising at least two plies of cellulose wadding, comprising associating said plies under pressure by passing between two cylindrical elements made of steel, the former being externally smooth and the second being externally provided with elements in relief and the hardness of the first cylindrical element being smaller than that of the second cylindrical element.
- the first cylindrical element has a treated, hardened surface layer and a deformable underlayer;
- the second cylindrical member has a hardened outer surface, and the sheet as it passes between the two cylindrical members is compressed to a specific pressure of 40 to 250 N / mm 2 .
- the difference in external hardness between the first and the second cylindrical element is between 2 and 20 HRC, preferably between 5 and 15 HRC.
- this difference in hardness creates a wear of the engraved cylindrical element slower than that of the first cylindrical element, which is an advantage because the engraved cylindrical element is an expensive element of the installation, more expensive than the first one. smooth cylindrical element.
- values between about 30 and about 65 HRC may be chosen.
- the method according to the invention advantageously allows to associate folds of width between 0.3 and 4 m, without wear problem of the cylindrical elements or variation in the quality of the association, regardless of the scrolling speeds folds.
- the subject of the invention is a set of cylindrical elements made of steel intended for the combination of multi-ply absorbent sheets, the first cylindrical element being externally smooth and the second cylindrical element being externally provided with elements in relief. outer hardness of the first cylindrical element being lower than that of the second cylindrical element, and said assembly for associating under pressure the different folds of the sheets by passing in the gap between their generatrices.
- the first cylindrical member has a hardened surface layer and a deformable underlayer
- the second cylindrical member has a hardened outer surface, the first cylindrical member being pressed against the second cylindrical member so as to exert on the absorbent sheet a specific pressure of between 40 and 250 N / mm 2 .
- the invention allows great flexibility in the choice of marking patterns, in the type of embossing, the arrangement and / or the quantity of patterns.
- the first cylindrical element may comprise a cylinder, or a set of several coaxial cylinders.
- the outer (surface) layer of the first cylindrical element has a thickness of between 3 and 30 mm, while the deformable underlayer, which is thinner, may have a thickness of between 0.5 and 10 mm.
- a hardness gradient of said outer layer of the first cylindrical element may advantageously be provided, depending on its thickness.
- said outer surface layer of the first cylindrical element may comprise two layers associated and superimposed on one another, the outermost being treated, cured.
- the outer surface (or ferrule) of the first cylindrical element, mounted on the deformable underlayer is a kind of shield that resists perfectly to mechanical stresses while maintaining overall flexibility to the cylindrical element.
- said deformable sub-layer comprises at least two layers having different mechanical characteristics.
- FIG. 1 is a simplified section of a "nip" between two cylindrical elements, according to a first embodiment of the invention
- FIG. 2 is a simplified section of a "nip" according to a second embodiment of the invention.
- - Figure 3 is a diagram showing the main elements necessary for the implementation of an embodiment of the invention.
- - Figure 4 is a diagram showing the main elements necessary for the implementation of another embodiment of the invention.
- the set of two cylindrical elements allowing the association of the plies comprises a first cylindrical element 1 commonly called a marrying cylindrical element which cooperates with a second cylindrical element. 2 says embossing.
- the marrying cylindrical element 1 has a smooth outer surface
- the cylindrical embossing element 2 externally has protuberances such as lines, spikes having one or two different depths, or more.
- the first marrying cylindrical element has an external hardness of hardness lower than that of the second cylindrical element.
- the first cylindrical element 1 has an external surface formed of two layers 111, 112 associated and superimposed on one another, the outermost 112 being treated, hardened .
- the first marrying cylindrical element has a hardened outer surface 11 which rests on a deformable underlayer 12 which itself may for example be made of a polymer.
- said sub-layer 12 may comprise at least two layers having different mechanical characteristics, in particular hardnesses and / or different resilience.
- the external hardness of the first cylindrical element can be achieved through a treated steel sleeve; or through a sleeve externally coated with a cured treated layer.
- the outer surface of the engraved cylindrical element 2 has a hardness greater than 2 to 20 HRC to that of the first matching cylindrical element 1.
- a hardness difference of between 5 and 15 HRC may be preferred.
- the HRC unit is a unit of hardness according to the test developed by ROCKWELL based on the following principle:
- a pointed body is penetrated into a metal test tube.
- a penetrating body is used a slightly rounded diamond tip whose apex angle is 120 °; this diamond point is gradually pushed into the metal and the residual indentation (e, in ⁇ m) of the tip under a given load is measured.
- ISO 6508 - 1 1999 provides a comprehensive definition of ROCKWELL hardness tests.
- the external hardness of the cylindrical element 2 etched can be achieved by a surface treatment which preferably relates to a thickness 22 greater than the height of the protuberances (or the highest protuberances) forming the etching.
- the absorbent sheet to be associated passes between these cylindrical elements where it undergoes a specific specific pressure, included between 40 and 250 N / m 2 .
- the specific pressure can be defined as the ratio between the total force applied by the first cylindrical element 1 on the second cylindrical element 2 at the nip, on the sum of the surfaces in contact at this point, at a given instant. It is therefore easy to understand that this pressure varies as a function of the geometry of the distal surfaces (ends) of the protuberances of the engraved cylindrical element 2, and that it can thus be controlled and controlled.
- the present invention advantageously allows a great freedom in the choice of protuberances, that is to say in fact embossing patterns of the absorbent sheet to be manufactured.
- the deformable underlayer 12 may be made of a compressible polymer such as an elastomer.
- This underlayer may have a thickness of between 0.5 and 10 mm; tests with thicknesses ranging from 2 to 4 mm gave very interesting results.
- the arrangement according to the invention makes it possible to reduce the deflection of the cylindrical embossing element 2 as well as the vibrations and other associated disadvantages.
- the marrying cylindrical element 1 is coated with a sleeve 11, which has a hardness of 47 HRC and is in contact with the engraved cylindrical element 2 which itself has an external hardness of 57 HRC .
- the elastic underlayer 12 has a thickness of 4 mm and is made of a compressible polymer such as an elastomer, known per se.
- the underlayer 12 advantageously makes it possible to dampen manufacturing defects, wear and / or vibrations at high speeds.
- FIGS. 3 and 4 show two examples of possible installations.
- FIG. 3 shows a first example according to which the elements used comprise, in addition to the marrying cylindrical element 1 and the embossed cylindrical element (of embossing) 2, a cylindrical rubber element 3 intended to cooperate with the cylindrical element 2 in order to emboss one of the folds (or groups of folds) P1 constituting the sheet F, according to a procedure known per se and which, therefore, will not be further explained.
- a second fold (or group of folds) P2 is brought into the gap (or nip) between the cylindrical elements 1 and 2 where it is associated with the first fold P1, as already described. This second fold is not embossed.
- a sheet F comprising two plies P1, P2 (or group of plies) is thus produced, with a first embossed ply and a second non-embossed ply.
- FIG. 4 shows the elements used to manufacture an absorbent sheet according to another embodiment of the invention, and which comprise, besides a marrying cylindrical element 1 and an engraved cylindrical element 2, a second engraved cylindrical element 4 and two cylindrical rubber elements 31, 32 which are counterparts to each of the cylindrical engraved elements 2, 4.
- first fold (or group of folds) P1 passes first between the first cylindrical rubber member 31 and the cylindrical element engraved 2 where it is embossed.
- second fold P2 passes between the second cylindrical rubber element (counterpart) 32 and the second cylindrical element engraved 4 for embossing purposes.
- the two plies (or group of plies) thus embossed separately, are joined between the first and second cylindrical engraved elements 2, 4 which are wedged so that the protuberances (or markings) of each of the plies are embedded in one another. other.
- This particular arrangement, called nested, is well known to those skilled in the art and will not be further described.
- the plies are then associated at the level of the nip 5 between the first etched cylindrical element 2 and the marrying cylindrical element 1, under conditions in accordance with the invention mentioned above.
- the first cylindrical element (1) may comprise a set of coaxial cylinders carried by one or more axes.
- the axes are angularly offset around the second engraved cylindrical element (2).
- a priori two axes are preferentially provided, diametrically opposed.
- each of the coaxial cylinders has characteristics in accordance with the invention, namely in particular a surface layer (11) treated, cured and a deformable underlayer (12).
