Definitions
- the present invention relates to the field of products for sanitary or domestic use made with sheets of absorbent paper such as cellulose wadding.
- the invention relates in particular to a sheet consisting of at least one embossed fold for use as a toilet paper essentially but also as a handkerchief, table napkin or possibly a paper towel.
- a generally creped absorbent paper of low grammage, cellulose wadding, also designated cotton fabric.
- the elongation capacity conferred by creping allows the sheet to be embossed. This operation consists of permanently deforming it between a rigid cylinder provided with reliefs or spikes on the surface and a counter-cylinder, for example with a resilient coating.
- the embossing is carried out in the present invention on paper with low humidity, during a step of transforming the sheet of paper downstream from the paper machine.
- the embossing patterns most often consist of elementary protrusions of small cross section and simple geometric shape. An example is described in US Patent 3,414,459 which relates to a sheet composed of several folds superimposed and glued together.
- the folds were embossed with a distribution frequency and a height of the protrusions suitable for the production of water-absorbing products, such as a paper towel.
- the number of elements ranges from 5 to 30 per cm 2 .
- the applicant has developed, for toilet paper in particular, patterns whose number of elements is greater, ranging from 30 to 80 or more per cm 2 . These latter elements necessarily have a very small elementary surface at the top. It is less than 1 mm 2 . An aspect which imitates that of a woven product is obtained for these latter embodiments.
- An example has been described in patent EP 0 426 548 in the name of the Applicant. This type of fine and dense embossing is well suited to induce an effect of thickness on the sheet. However, it has limited visual appeal.
- the solution presented in patent EP 797 705 consists in producing a combined pattern, comprising a graphic pattern and a background pattern.
- the first is made up of protuberances whose shape is called linear. These have an elongated, curvilinear shape, with a width of between 0.1 and 2 mm.
- the second pattern includes small protuberances, generally frustoconical, distributed at a rate of at least 30 per cm 2 . This solution allows a wide choice of patterns while offering a good compromise between softness and sheet thickness.
- the present invention relates to a sheet comprising at least two superposed plies of absorbent paper, such as cellulose wadding, each of grammage between 10 and 40 g / m 2 , at least one of which has been embossed so as to present on its external face of the cavities corresponding to protuberances on its other face adjacent to the second fold.
- the subject of the invention is such a product which combines thickness and softness to the touch.
- the sheet is characterized in that the first fold comprises first zones forming cells with first cavities, the cells being surrounded by second zones with second cavities, the first zones being in relief on said external face with respect to the second zones with a difference in level, the first zones presenting a contour with a line of marking.
- the solution of the invention by the effect produced by the pads formed by the first zones, gives the product an impression of remarkable thickness.
- this impression of thickness is confirmed by touch.
- the protuberances corresponding to the cavities structure the surface of the first zones by offering resistance to crushing. This resistance to crushing gives volume to the sheet.
- the presence of the second cavities further enhances the relief effect, in particular when these are at least partially aligned with the contour of the first zones.
- the marking makes it possible both to reinforce the visual effect given by the raised areas and their resistance to crushing.
- the height of the first protrusions is at most equal to the height of the second protrusions, increased by the difference in level between the first and the second zones.
- the product comprises third non-embossed zones between the different second zones which, by contrast, increase the impression of thickness.
- the third zones can be embossed.
- the first protuberances are of frustoconical shape, and at least part of the first zones comprises third protuberances of linear shape.
- the second fold superimposed on the first fold is not embossed.
- the second fold is embossed. It may have protuberances arranged so that the two plies are in contact with the tops of the second protuberances.
- the present invention also relates to a device for manufacturing a sheet.
- It comprises at least one rigidly coated cylinder suitably engraved so as to present first zones forming cells surrounded by second zones, the first zones comprising first pins and the second zones comprising second pins, the background of the engraving of the first zones being at a level, measured with respect to the axis of the cylinder, lower than that of the second zones.
- the top of the first pins is at a level below that of the tops of the second pins.
- the transition surface between the first zones and the second zones is constituted, at the less in part, frustoconical surface elements defining a so-called pinch edge. This arrangement marks the outline of the first zones which stand out in contrast to the second and third zones.
- the contour forms a closed perimeter.
- FIG. 1 shows a top view of an embossed sheet in accordance with an embodiment of the invention
- - Figure 2 shows a view in perspective, in partial section of the sheet along line II II of Figure 1
- - Figure 3 is a view of an embossing machine for producing the product of the invention
- - Figure 4 shows the detail d 'a cylinder engraved according to the motif of the invention.
- - Figure 5 is a cross section of a sheet according to another embodiment of the invention
- - Figure 6 is a cross section of a sheet according to yet another embodiment of the invention
- - Figures 7A and 7B respectively represent the front and back of a sheet according to an embodiment according to that of Figure 6
- - Figure 8 illustrates an embossing characteristic of an additional embodiment.
- the sheet shown in Figures 1 and 2 is a sheet consisting of two plies PI and P2 of absorbent paper, for example creped cellulose wadding.
- the grammage of the paper is preferably between 10 and 40 g / m 2 .
- the sheet comprises a first embossed fold PI, called upper, and a second fold P2, called lower.
- the second fold is not embossed.
- the upper fold is for example of the type obtained according to a conventional wet pressing process which is usually designated in the field by CWP or else a paper obtained according to a process with drying of the sheet by air passing through which is designated by TAD .
- the bottom fold can be CWP or TAD paper.
- a papermaking process, of the CWP type consists of depositing the paper fibers suspended in water on a canvas to form a sheet. The sheet is drained and then transferred to a felt which will allow it to be applied with a press against a drying cylinder. The sheet is peeled off and is creped using a doctor blade. Finally, it is put on reel awaiting transformation into a finished product.
- a TAD type technique consists, after draining, of drying the sheet without exerting pressure, at least in part, until sufficient dryness to freeze the fibers within the sheet. If necessary, the drying is finished by applying the sheet to a heated cylinder. Thanks to this first drying, the sheet can be pressed on a heated cylinder; it retains part of its volume. This cylinder also allows its creping. Drying is carried out without pressure by blowing hot air through the sheet after draining.
- This TAD technique makes it possible to obtain thicker sheets, of greater mass volume, than the so-called conventional technique. Referring to Figure 1, we see a combination of dots and lines. The points represent cavities or protuberances depending on the face of the fold that is observed.
- the lines also represent cavities or protuberances depending on the face observed. Their shape is elongated. Certain lines represent simple markings as will be seen below.
- the cavities / protuberances are obtained by deforming the sheet between a tool with a rigid surface such as a cylinder engraved in steel, and a rubber counterpart for example.
- the rigid surface of the cylinder has reliefs arranged according to the pattern which it is desired to obtain on the cellulose wadding sheet.
- the pins have a substantially trapezoidal profile in the height direction. If they are tapered, they have a cross section relative to their axis, circular, oval or polygonal. In Figure 1, considering that this is the outer face of the sheet, we see the cavities 12 distributed inside the first zones Ai.
- zones Ai are themselves regularly distributed here over the entire surface of the sheet in a pattern with constant pitch in two directions perpendicular to each other. One of the directions is slightly inclined with respect to the machine direction represented by the direction L and which corresponds to the direction of travel of the sheet during its manufacture.
- Ai is delimited by a solid line D obtained by marking the sheet, as will be explained below. Outside the marking line D, each zone Ai is surrounded by a second zone A 2 made up of cavities aligned parallel to the marking line D. Between the different second zones A 2 , there are third non-embossed zones A. Certain first zones, designated A'i, include first cavities 12 and also third cavities 20 as visible in FIG. 2. Referring to FIG. 2, the different zones are shown in section, in more detail. We see the sheet partially from above with the upper Pi fold superimposed on the lower P 2 fold. The embossing on the fold Pi defines several zones Ai, A 2 and A 3 . The first zones Ai are in relief with respect to zones A and A.
- first protuberances 12 of generally frustoconical shape projecting inside the sheet. Each protuberance forms a cavity on the external face of the fold Pi.
- the protuberances have a height which is at most equal to the distance separating the external face of the fold Pi at P 2 . According to the embodiment of the figure, the height is lower. It corresponds substantially to the height of the area Ai with respect to the reference plane formed by the areas A 2 and A 3 .
- the zone Ai comprises between 30 and 100 protrusions per cm 2 , preferably between 30 and 60. Because of this high number of protrusions per unit of area, the dimensions thereof are necessarily limited.
- the overall height of these protrusions is between 0.3 mm and 1 mm.
- the diameter of the flat at the top is here of the order of 0.4 mm.
- the zones Ai are delimited by an inclined wall 14 whose lower edge forms a line D of separation with the adjacent zone A 2 . This line is clearly visible because it is obtained by marking the sheet.
- the fold Pi preferably forms an internal edge along this line D.
- second protuberances 18 At the edge, outside of the zones Ai and along this line D, there are second protuberances 18 also projecting inside from the sheet, towards the fold P 2 .
- These protrusions are here aligned in two parallel rows along the line D.
- the second protrusions can be of the same dimensions as the first. They are in contact with the lower fold P 2 by their top. They ensure the connection therewith in particular by means of an adhesive film.
- FIG. 3 a machine as shown in FIG. 3 is preferably used.
- This machine comprises a first rotary cylinder 100, made of steel or other rigid material, suitably etched on the surface according to the pattern which makes it possible to produce the embossing, the pattern of which is shown in FIG. 1.
- a rubber cylinder 110 is rotatably mounted on an axis parallel to the first. It presses on the cylinder by means of suitable jacks not shown.
- a first strip of paper is guided, from an upstream reel, around the cylinder 110 and then between the two cylinders 100 and 110.
- the sheet then follows the relief of the cylinder 100 by the pressure of the rubber. Depending on the pressure of the cylinders and the nature of the rubber, the paper penetrates more or less deeply inside the engraved pattern. The fineness of it is also a parameter that must be taken into account.
- the sheet pressed against the cylinder 100 then passes in front of a sizing machine 104 which applies glue to the top of the elements in relief.
- the glue here is a cylinder with a rigid surface which receives glue from a doctor blade chamber, for example.
- a second strip of paper from a second reel for example is deposited against the first strip by a matching cylinder 106.
- the film of adhesive on the first sheet Pi migrates partly on the parts of the second strip P 2 which come into contact with the raised parts of the strip Pi. The two folds are thus linked together by these contacting surfaces.
- the two-ply sheet is then rolled up for further processing.
- Other methods than this can be applied, depending on the product one wishes to obtain. It is possible, for example, to replace the roller 106 with a second embossing unit and to associate the plies in point-to-point mode or else in nested mode with a matching cylinder as is known to those skilled in the art.
- FIG. 4 shows a sectional portion of the surface of the cylinder
- the cylinder includes an engraving here on three levels.
- the levels are defined relative to the axis of rotation of the cylinder.
- the upper level Ns is that of the surface forming the overall envelope of the cylinder.
- Ni is that of the surface at the bottom of the engraving of the zones Al or A'1.
- First spikes 112 are observed, of frustoconical shape, which protrude relative to the etching bottom of level Ni.
- the pins 112 have a height such that their apex is at the reference level N.
- the pins 112 are arranged in cavities hollowed out on the cylinder defining the zones A1.
- These cavities are bordered by a wall 114 which cuts the reference surface of level N, along lines forming an edge D A. Along this edge, the tangent to the wall 114 makes an angle between 20 and 50 ° relative to the direction perpendicular to the axis of the cylinder. Preferably, the angle is between 25 and 35 °.
- a wall 114 which cuts the reference surface of level N, along lines forming an edge D A. Along this edge, the tangent to the wall 114 makes an angle between 20 and 50 ° relative to the direction perpendicular to the axis of the cylinder. Preferably, the angle is between 25 and 35 °.
- These second pins define second zones A2. The surface portions formed between the different zones A2 are not engraved, they are at level N. They constitute the third zones A3.
- third pins 120 of non-frustoconical shape but whose apex is of elongated shape.
- the dimensional parameters are as follows: N-Ni, that is to say the depth of the etching cavities which correspond to the first zones Al in relief after embossing, is between 0.1 and 1.3 mm.
- the embossing of the fold PI leads to areas Al having a difference in level NA with the reference plane.
- the difference in Ns-Ni levels is between 0.2 mm and 2.0 mm.
- the height of the pins 112 is between 0.1 mm and Ns-Ni.
- the height of the pins is between 0.5 and 0.9 with a difference in level Ns-Ni greater than 0.5 mm.
- the height of the pins 120 inside the zones A'1 is preferably between 0.1 mm and Ns-Ni. Preferably, it is equal to Ns-Ni so in particular that the corresponding protrusions on the paper form areas of connection with the adjacent fold.
- the rubber is applied with sufficient pressure to the etched surface so that it penetrates into the cavities of the zones Al.
- a concentration of the stresses at the level of the edge leads to a pronounced marking of the sheet along this edge line. It contributes to forming the relief of the area Al, in particular by the shade that the marking produces when the sheet is lit in inclined light.
- the parameters are chosen so that the rubber follows the pins to get as close as possible to the Ni level.
- a sheet is shown, in cross section: the fold PI is embossed as described above while the fold P2 is smooth. Such a sheet has a maximum thickness h.
- FIG. 6 shows, in cross section, another embodiment of the invention according to which the two folds PI and P2 each have a different embossing. More precisely, the embossing produced on the first ply PI is almost identical to that described above while that of the second ply P2 is as visible in FIG. 5.
- the embossing of the second ply P2 and its arrangement opposite of the first fold are such that the micro-embossings present inside each cell defined by the marking line D, are arranged opposite, that is to say in point-to-point contact with the corresponding micro-embossing of the first PI fold; in other words the first cavities 12 are arranged opposite cavities 12 ′ of the second fold P2.
- the tops of the second cavities 18 of the first ply are provided with glue and therefore serve as connection points with the second ply P2; at this level the fold P2 is smooth.
- a sheet is thus obtained, the front and back of which are respectively presented in FIGS. 7A and 7B, given by way of illustration and in no way limitative.
- it has been chosen to arrange the micro-embossed areas of each ply one opposite the other.
- an identical pitch can be provided for the micro-embossings of each of the plies.
- the micro-embossings produced inside each of the cells delimited by the contours D may have different pitches.
- the embossing cylinder of the second fold is hollowed out in order to achieve the aforementioned arrangement.
- This arrangement results in a sheet whose relief is even more marked than that of the first embodiment of the invention.
- the distance H from vertex to vertex that is to say the thickness is greater than the distance h (thickness) measured on a sheet produced according to FIG. 2 for example.
- the fact that the two faces of such a sheet have different embossings constitutes an unexpected and pleasant aspect for the user.
- one of the folds may have an embossing close to that of Figure 1; the difference consisting in adding cavities (or protrusions) A 4 between the second zones A 2 .
- Said cavities can be in the form of continuous lines as shown in FIG. 8, or possibly of point alignments.
- linear patterns are provided.
- these linear cavities (or protrusions) represent bonding points between the folds, preferably uniformly distributed over the whole of the embossing. This strengthens the connection between the folds while improving the external appearance and in particular the relief given to the product.
