Definitions
- the invention relates to the field of fibrous products, in particular sanitary and household papers, made of cellulose wadding. It relates to a method of embossing a sheet with one or more plies, as well as a sheet of embossed paper for the purpose of use as toilet paper, napkin or paper towel in particular.
- embossing a sheet with one or more plies as well as a sheet of embossed paper for the purpose of use as toilet paper, napkin or paper towel in particular.
- it is sought to produce products which have bulk because this character is associated by the user with the properties of absorption, softness and appearance.
- the bulk is increased by embossing the sheet and, if necessary, by making a sheet from two or more embossed plies.
- US Pat. No. 3,556,907 is known, which teaches a method of making paper, in particular with two folds or elementary sheets of crepe paper.
- the plies are embossed separately, with protrusions or bosses on one side, and are combined by bringing said faces closer to one another with interlocking of the protrusions; the installation comprises two embossing units, each with a steel cylinder and a rubber cylinder, and a matching cylinder separate from the embossing cylinders.
- the matching cylinder made of rubber, cooperates with one of the metal cylinders to ensure the association of the folds.
- the sheet which has been embossed by the cylinder not in contact with the matching cylinder undergoes, due to its capacity to elongate, a slight but noticeable deformation, when it is detached from its cylinder to come under the matching cylinder . It is therefore necessary to provide sufficient spacing between the protrusions to allow their nesting. The maximum allowable density is thus limited. In fact, a high density would cause the protuberances to overlap.
- US Patent 3940529 describes an absorbent two-ply product.
- the folds each have a pattern made by embossing with depressed areas and raised areas.
- the raised areas on one fold are arranged between the raised areas of the other fold. and the connection is made by mechanical welding of the sides between the bottom and the top of the reliefs. This mechanical welding results in a loss of mechanical strength with perforation of the sheet at this level.
- the installation comprises two metallic embossing cylinders, provided with reliefs or spikes, meshing one inside the other.
- the distance between the elementary reliefs is less than their width so that the sheet is strongly compressed along the sides of these reliefs, and welded.
- US Pat. No. 4,325,773 describes a method of assembling two plies where the latter have been previously embossed separately.
- the two embossing cylinders, meshing one inside the other, ensure the association of the folds. It is observed that the embossing pattern consists of reliefs of elongated shape relatively spaced from each other.
- US Patent 4,759,967 describes an embossing mode for a multiple sheet consisting of bonding the plies together beforehand by means of an adhesive spray and then embossing the sheet between two metallic embossing rolls.
- the embossing pattern on the cylinders consists of alternating cavities with raised areas relative to the plane of the surface. The two cylinders mesh with one another, the reliefs of a cylinder engaging in the cavities of the second. It should be noted that these cylinders have been engraved together.
- the thickness el at the level of the ply bonding zones equal to the sum of the thicknesses of the plies, is less than that e2 of the zones, intermediate between two zones of collage, which form air pockets.
- the subject of the invention is a method of manufacturing by embossing a sheet with at least one fold according to which the latter is engaged between two metal cylinders provided with protuberances, driven in rotation by means known per se, and meshing with each other with a clearance el between the apex of the protuberances of a cylinder and the surface of the cylinder opposite, and a clearance e2 between the sides of two adjacent protuberances.
- This process is characterized in that el and e2 are determined in the transverse direction with respect to the machine direction so that the ratio el / e2 is between 0.8 and 1.
- a sheet which combines the advantage of a rubber / steel embossing and a steel / steel embossing, that is to say a sheet the thickness of which is substantially uniform. by presenting an improved softness by the effect of calendering produced on the top of the raised areas of the sheet.
- a sheet with at least two plies is produced by causing at least one of the two plies to match the surface of one of the cylinders in the application by means of a rubber cylinder.
- the two folds can be shaped beforehand and glued by depositing an adhesive on at least part of the raised areas on the cylinders before they are combined.
- the clearance el is between 5/100 and 5/10 mm and corresponds at most to the sum of the thicknesses of the folds constituting the sheet.
- a sheet with at least two folds is thus produced, which, compared to a sheet of prior art of the nested type, "nested", may include a greater number of bosses. This results in better resistance to crushing.
- rollers with a smaller diameter can be obtained for the same sheet length, which reduces the storage volume.
- the calendering effect produced by contact with the two metal cylinders provides softness to the touch.
- Figure 1 shows in section a two-ply sheet of the prior art.
- Figure 2 shows in section the combination of two conjugate cylinders of the prior art.
- FIG. 3 represents an installation allowing the implementation of the invention for the production of a sheet with one fold or with several folds previously bound.
- FIG. 4 represents a sectional view along IV of FIG. 3.
- FIG. 5 represents an installation allowing the implementation of the invention for the production of a sheet with at least two folds.
- FIG. 6 represents a sectional view along VI of FIG. 5.
- FIG. 7 shows another embodiment for producing a 3-ply paper.
- Figure 1 shows, in cross section, a sheet 1 of the prior art with two folds 2 and 3 nested one inside the other.
- the method of manufacturing such a sheet is taught for example in US patent 3556907.
- the fold 2 has bosses 4 obtained by embossing, these bosses are spaced regularly from each other and turned towards the fold 3 which also has bosses 5, .turned towards the fold 2. These are fitted between the bosses 4.
- the spacing between the bosses 4 and 5 is sufficient to create a vacuum 6 between them.
- the thickness of the sheet varies between a minimum value el where the bosses of a fold are in contact with the opposite fold, and a value e2 between two adjacent bosses.
- the ratio e1 / e2 is low, of the order of 0.1. Indeed, it corresponds to the thickness of the 2 plies of crepe absorbent paper, for example 0.2 mm and e2 was measured at 1.85 mm.
- Figure 2 shows the embossing interval of two cylinders, in section in the plane passing through the axis of the two cylinders.
- the metal cylinder 7 has radial projections 8 regularly distributed on the surface; similarly the cylinder 7 'has projections 8' of the same dimension.
- the usual technique of engraving a pair of such cylinders consists in engraving a first cylinder by means of a wheel made of a material harder than that of the cylinder. Once this first cylinder is made, the second cylinder is engraved using the first so as to obtain two conjugate patterns which perfectly overlap one another.
- FIG. 3 Schematically shown in Figure 3 an embossing installation 10 of a sheet with a fold or a multiple sheet previously bonded, with two cylinders 11, 12 arranged in parallel and driven by conventional means in the direction of the arrows.
- the cylinders 11, 12, made of metal or of another equivalent material, are provided, on the surface, with pins 13, 14, extending radially outwards.
- the cylinders are positioned relative to each other so as to mesh with one another, the pins 13 of the cylinder 11 coming to be placed between the pins 14 of the cylinder 12 in the embossing interval .
- the sheet 15 of crepe paper is engaged between the cylinders 11 and 12 and emerges therefrom having on each face of the bosses corresponding to the pins of the cylinders.
- Figure 4 is an enlarged view of a section made by a plane passing through the axis of the two cylinders and shows a configuration of the pins according to the invention.
- the pins are identical on the two cylinders and are distributed in the same pattern with steps in the direction of travel, respec ⁇ tively in the cross direction, identical.
- the running direction is that of the direction of scrolling of the sheet; the creping lines are perpendicular to it.
- the transverse direction is defined as forming an angle of plus or minus 45 ° relative to the perpendicular to the running direction.
- the pattern has a transverse direction perpendicular to the running direction.
- the pins have a height of between 0.5 and 1.5 mm.
- the embossing interval between the two cylinders is equal to el between the top of the pins 13 of the first cylinder and the bottom of the engraving between the two adjacent pins 14 of the second cylinder. It is equal to e2 between the flanks of two adjacent pins 13 and 14.
- the clearance el is a function of the spacing which has been fixed between the two cylinders.
- the value of the e2 clearance depends, for its part, on the geometric parameters of the pins.
- P of the given pattern it is a function of the angle at the top ⁇ of the pins as well as their width L at the top. In practice the angle ⁇ is between 25 and 35 ° and the width at the top is 0.1 and 1.2 mm.
- el and e2 are determined so that the ratio el / e2 is less than or equal to 1 and greater than 0.8.
- the value el will be chosen at most equal to the thickness of the sheet to be embossed. This ensures calendering of the sheet at the top of the bosses obtained, providing improved softness to the touch.
- FIG. 5 shows an embossing installation for the formation of a two-ply sheet.
- This installation per se of the conventional type comprises two cylinders 111, 112, made of metal or an equivalent material, arranged in parallel and driven by conventional means in the direction of the arrows.
- the cylinders 111 and 112 are provided with pins 113, 114 extending radially outward and meshing with one another.
- a pressure cylinder 119, 120 coated with rubber or other elastomeric material is associated with each of the cylinders 111 and 112.
- Two plies of crepe paper 115, 115 ′ are engaged respectively between the cylinders 111 and 119, and 112 and 120 and are pressed on their respective embossing cylinder, the relief of which they follow.
- a sizing device 121 also known per se, deposits an adhesive substance on the tops of the raised areas of the fold 115, then the two folds are entrained in the embossing interval between the two rolls 111 and 112 where they combine into one sheet.
- This sheet 115-115 ' is then transformed into a finished product such as, for example, a household paper towel.
- FIG. 6 represents an enlarged view of a section made along a plane passing through the axis of the two cylinders 111 and 112.
- the two folds 115, 115 ' substantially match the outline of the pins 113 and 114 respectively.
- the clearance between the two cylinders is equal to el between the tops of the pins and the bottom of the engraving facing it. It is equal to e2 at the flanks.
- the clearance el is determined so that it is at most equal to the thickness of the two plies so as to ensure on the one hand the bonding at this level, on the other hand an action of calendering.
- the geometry of the pins is determined so that the ratio el / e2 is between 0.8 and 1. This ensures the formation of a sheet, where the air pocket is reduced.
- the value of the ratio el / e2 has been determined so that it is between 0.2 and 1. In particular, this must be between 0.2 and 0.5.
- FIG. 7 shows an embodiment of a 3-ply sheet. The installation is similar to that of FIG. 5. Each common element has been designated by the same reference. It includes an additional sizing machine 122 and a 115 "paper feed.
- Each of the glueers 121, 122 deposits an adhesive substance on at least part of the tops of the reliefs of the plies 115 and 115 ". These are applied against the metal cylinders 111 and 112 by means of the rubber cylinders 119, 120.
- the two plies 115, 115 ' are driven in the direction of the arrows as far as the engagement interval of the two cylinders 111 and 112.
- a third fold 115 " is driven between the two folds 115, 115' at the time of their engagement in said interval. Thanks to the invention, with el / e2 and el less than or equal to the sum of the 3 ply thicknesses, the plies 115 are connected with 115 "and 115" with 115 '.
