Definitions
- the present invention relates to the field of absorbent papers for sanitary or domestic use, and aims a sheet composed of at least three folds of absorbent paper, the plies being embossed.
- the field of sanitary and domestic paper relates, without limitation, products intended to be applied to the skin, such as towels for cosmetic use, tissues, toilet paper, or for wiping such as wipes -all, wiping cloths, or used for the table, such as napkins.
- a wet absorbent paper is used, which is then processed in a dry phase of manufacture.
- the paper obtained by wet process, designated cellulose wadding is manufactured according to conventional techniques known as CWP for "conventional wet pressed" or with through-flow known as TAD for "through air dried".
- the paper is made more particularly so as to have a certain capacity of elongation, in particular by creping.
- emboss the sheet By embossing, the sheet is deformed in places permanently, in order to obtain protuberances on one side of the sheet.
- the embossing makes it possible to increase the thickness of the sheet but also to make it more flexible because of the breaking of interfiber bonds that it entails.
- the aim is to make the sheet softer, softer and more attractive while maintaining or improving the functional characteristics of thickness and resistance in particular. These can be affected, improved or degraded by the embossing process.
- the embossing operation is performed on paper with low humidity, that is to say in transformation in the dry part.
- a plurality of plies are associated with each other for the purpose of obtaining a thick product.
- the folds are superimposed generally so that the protuberances are turned towards the inside of the sheet as far as a soft-touch surface is desired.
- the protuberances between the adjacent plies form between them cavities giving softness to the sheet while ensuring a good absorption capacity.
- the protuberances may be either arranged vertices against vertices in the so-called tip / tip position, which in principle gives the maximum thickness to the sheet. They can also be arranged so as to nest. The thickness is less than in the point / tip position, but this arrangement is suitable for applications related to wiping where the density of embossing protuberances is low,
- the present invention relates to a product composed of two or more plies, each having an embossing pattern.
- the document EP 1 772 257 relates to the manufacture of associated tip / tip embossed composite products whose embossing patterns are designed so as to also avoid the phenomenon of nesting.
- the solution is to emboss the two plies separately according to patterns of which at least a part - AT -
- each of the folds has an elongate shape in one direction.
- the directions of each of the folds form an intersection between them.
- the two patterns are arranged to allow the manufacturer to choose between the point / tip relationship and the interlocking relationship of the two patterns.
- No. 3,738,905 proposes an embossing pattern formed of planar surfaces and cavities. Folds are associated along flat surfaces arranged along continuous lines.
- the problem that the invention aims to solve is therefore that of producing a sheet of paper having at least two embossed folds, in a pattern formed at least in part of protuberances elongate in the plane of the sheet, whose rigidity is controlled.
- this problem is solved with a sheet of absorbent paper comprising at least a first and a second corrugated ply of cellulose wadding, of grammage between 10 and 40 g / m 2 , each of the plies comprising protuberances. on the inward side of the sheet corresponding to cavities on the outer side, with first protuberances on the first elongate fold, first protuberances on the second elongate fold, at least a portion of the first protuberances first ply being in contact with at least a portion of the first protuberances of the second ply.
- the sheet according to the invention is characterized in that the first fold and the second fold each comprise second protuberances of frustoconical shape, at least a portion of the first protuberances being adjacent at least in part to second protuberances, the first protuberances of said first ply are aligned in a first direction and the first protuberances of said second ply are aligned in a second direction, the two directions forming a non-zero angle alpha between them, at least a portion of the second protuberances forming alignments interposed between two alignments of first protuberances.
- the frustoconical shape includes protuberances circular section parallel to the plane of the sheet but also oval or polygonal, especially square, and whose ratio of the largest dimension to the smallest is small, less than 2.
- adjacent protuberances adjacent protuberances are designated in the immediate vicinity of each other without the interposition of any other protuberance.
- protuberances By elongate protuberances are meant protuberances whose section, made parallel to the plane of the sheet, forms a line or a segment.
- the ratio of the dimension in the direction of the length to the dimension transverse to the line, ie the width, is greater than three. It is preferably greater than five.
- the length of the line or segment is preferably also in a ratio of less than twenty and more particularly less than ten with the width; this line can be closed.
- the invention benefits from the crossing of the elongated protuberances which ensures contact between the two folds, insofar as the alignments between the elongate protuberances of the two folds form a sufficiently high angle.
- the best yield is obtained with a cross at right angles.
- At least a portion of the second protuberances form alignments interposed between two alignments of first protuberances.
- the first protuberances are arranged alternately along an alignment, with at least one second protrusion.
- the first protuberances are in the form of segments, the latter being parallel to each other.
- the said segments are rectilinear or with a curved portion.
- the width of the first protuberances is equal to that of the second protuberances.
- the length of a first protrusion is between 3 and 20 times the width of a second protuberance, preferably between 3 and 10 times and more particularly between 5 and 10 times.
- the first protuberances of the first fold are identical to the first protuberances of the second fold.
- the absorbent paper sheet comprises at least a third embossed ply, superimposed on the second fold.
- the third fold comprises first and second protuberances, the orientation of the first protuberances of the third fold being the same as the orientation of the first protuberances of the first fold.
- the paper sheet of which at least one of the folds comprises third protuberances, the height of the third protuberances being greater than those of the first and second protuberances.
- Figure 1 shows a sheet of paper with two folds, seen from above, with the design of the protuberances of each of the folds, that of the lower fold being formed of fine lines;
- Figure 2 is a cross-sectional view of Figure 1;
- Figure 3 is a cross-sectional view of a sheet according to the invention composed of three plies.
- Figure 4 is a top view of a sheet according to the invention, one of the folds comprising third protuberances.
- Figure 1 illustrates the relative arrangement of the two plies 10 and 20 constituting a sheet 1.
- the two plies are absorbent paper, preferably creped tissue paper.
- the basis weight of the paper is between 10 and 40 grams per m 2 .
- a first ply 10 is embossed with an embossing pattern formed by first protuberances 11 and second protuberances 12.
- the second ply is embossed with an embossing pattern formed by first protuberances 21 and second protuberances 22.
- the first protuberances 11, 21 are in the form of segments here rectilinear and the second protuberances are of frustoconical shape with oval section, parallel to the plane of the sheet.
- the length of the first protuberances is, in this example, in a ratio four with the length of the second protuberances.
- the protuberances have substantially the same widths.
- the first protuberances 11 form alignments of segments parallel to each other, separated by disk alignments of the second protuberances 12.
- the pattern of the first ply 10 has an alternation of first protuberances 11 and second protuberances 12. This alternation is as well in the direction of the length of the segments 11 only in the direction of their width.
- the height of the first protuberances 11 is in this example the same as that of the second protuberances 12. However it also enters in the object of the invention to produce second protuberances of lesser height.
- the two patterns are, in this example, identical with this difference that the pattern of the lower fold 20 of the figure is rotated by an angle alpha with respect to the pattern of the upper fold 10.
- the angle is defined between the main directions of the two reasons.
- the embossing is performed by deformation of the folds, each on an embossed rigid embossing cylinder.
- the engraving is composed of pins, raised on the surface of the cylinder, corresponding to the protuberances to be obtained.
- the first protuberances 11 or 21 must have a width of between 0.2 mm and 1.2 mm.
- the corresponding width of the second protuberances 12 or 22 is for example equal to that of the first protuberances.
- the spacing between two adjacent studs measured at their base is preferably at least 0.15 mm.
- the contact between the two folds is provided by the first protuberances 11 and 21 of the two folds.
- an angle alpha is determined as a function of the length "1" of the first protuberances 11 and 21 and the distance "e” separating two first protuberances 11 and 21 adjacent in the direction perpendicular to the main direction of these, the mean direction for the present example.
- the angle ⁇ is thus chosen such that sinoc is at least equal to the ratio e / 1.
- FIG. 2 shows the section of a sheet with two plies, but it is preferred to associate a third ply 30 embossed with a pattern having the same alignments of first and second protuberances as the first ply and to arrange it. with the same orientation as the first fold. This embodiment is shown in FIG.
- the invention is not limited to the embodiment shown.
- the first protuberances may have a curvilinear shape or even a closed form.
- the curvilinear shape can be that of a capital "S”.
- the first protuberances remain aligned.
- FIG. 4 shows a variant embodiment of a sheet according to the invention in which at least one of the plies comprises third protuberances 13.
- these third protuberances have a height relative to the plane of the sheet which is greater than that of the first 11 and the second protuberances 12.
