  • the printing unit may be a flexographic printing device or any optional printing device adapted to print on paper or nonwoven.
  • the first paper web is then fed towards a glue application station. This comprises a glue chamber 3 from which glue is applied on a glue roll 4.
  • the glue roll 4 is in contact with a first patterned glue transfer roll 5, which along its periphery is provided with a pattern of protuberances 6.
  • the glue roll 4 is only contacting the tops of the protuberances 6, so that glue is applied only thereon.
  • the paper web 1 is passed into a press nip between the glue transfer roll 5 and the centrally placed impression roll 7. Glue will thus be applied to the first paper web 1 in a pattern corresponding to the configuration of the tops of the protuberances 6.
  • the printing roll 15 is driven in register with the glue transfer roll 5.
  • the printing pattern is in register with and preferably not overlapping with the glue pattern.
  • the term "in register with” generally refers to that two or more patterns are applied with fixed relationship to each other, and are either overlapping or non- overlapping.
  • the term "overlapping" includes that the patterns are located just above each other or are only partly covering each other.
  • the pressure in the press nip between the glue transfer roll 5 and the impression roll 9 is low and only sufficiently high to accomplish a transfer of glue to the paper web 1. According to one aspect of the invention no or only a slight deformation of the paper web takes place, i e no distinct impression of the protuberances 6 of the glue transfer roll 5 into the paper web will occur.
  • a second paper web 8 is fed over a roll 9 and into a press nip between a patterned lamination roll 10 and the centrally placed impression roll 7.
  • the lamination roll 10 has a three dimensional pattern of protuberances 11 corresponding to the pattern of the protuberances 6 on the glue transfer roll 5.
  • the term "corresponding to” in this respect means that the protuberances 11 either have the same shape and size of the effective surface area as the protuberances 6 of the glue transfer roll 5, the same shape but a larger effective surface area than the protuberances 6 of the glue transfer roll 5 so as to extend outside the outer circumference of the glue sites provided by the glue transfer roll 5, or a different shape and a larger effective surface area than the protuberances 6 of the glue transfer roll 5.
  • a glue pattern 12 provided by the first pattern roll 5 may be in the form of groups of three dots 13 arranged in a triangular pattern as shown in Fig. 1 and 2, wherein the protuberances 11 of the lamination roll 10 may either be exactly the same as or slightly larger than the glue pattern, or may for example be in the form of a triangle 14 covering the three dots. In all these cases the relative positions of the patterns on the glue transfer roll 5 and the lamination roll 10 are in correspondence with each other.
  • the glue transfer rolls 5 and the lamination roll 10 are driven in register with each other so that the first and second paper webs 1 and 8 are pressed and glued together in a pattern corresponding to the configuration of the glue pattern provided by the glue transfer roll 5.
  • one centrally impression roll 7 is used for both the glue transfer roll 5 and the lamination roll 10, as is shown in Fig. 1.
  • the pressure should be sufficiently high to provide a gluing together of the two paper webs 1 and 8.
  • the pressure in the second press nip should preferably not be higher than to cause only slight compacting impressions just opposite the glue sites in the second ply 8 facing the lamination roll 10.
  • the pattern on the glue transfer roll 5 can be optional, but should be chosen so that glue is applied to the paper web 1 in an amount corresponding to between 0.03 and 9%, preferably between 0.1 and 6% of the total surface area of the paper web 1.
  • the glue sites 13 are sparsely distributed over substantially the entire area of the laminated product. It is with the method according to the invention possible to provide a very distinct positioning of the glue sites 13, wherein a very small amount of glue is needed. This means advantages with respect to softness, drapability, absorption etc.
  • the number of glue sites 13 per area unit should amount to between 25 and 350000 glue sites per m 2 , preferably between 300 and 180000 glue sites per m 2 and more preferably between 800 and 50000 glue sites per m 2 .
  • the size of each glue site 13 should amount to between 0.15 and 150mm 2 , preferably between 0.5 and 100mm 2 and more preferably between 1 and 15 mm 2 .
  • each glue pattern unit is built up of a plurality of small screen dots.

  • the printing pattern provided by the printing roll 15 will appear on the inside of the laminated multiply product, and will be visible through the plies, in case the printing pattern is a coloured pattern.
  • the printing pattern is a surfactant, a skin care agent or other functional chemical it may be of advantage to have the chemical substance on the inside of the laminated product, so that it is protected during the converting process and before use and becomes active only after wetting of the paper.
  • a second printing roll 16 is arranged after the lamination roll 10 for printing on the outside of the second web shaped material 8.
  • This second printing unit may also be a flexographic printing device or any optional printing device adapted to print a colorant, a surfactant, a skin care agent or other functional chemical on paper or nonwoven.

  • two or more printing rolls may be provided, which print in subsequent steps on said second web shaped flexible material 8 after lamination to the first web shaped flexible material 1, said patterns being printed in register with each.
  • the lamination roll 10 may further act as a printing roll carrying a colorant, a skin care agent or other functional chemical in a selected pattern, which is printed on the outside of the laminated product. This is shown in the embodiment of Fig. 2.

  • the glue pattern 12 is in the form of groups of three dots 13 arranged in a triangular configuration.
  • the glue pattern may be coloured or colourless, so that it either does or does not form part of the patterning effect of the multiply web.

  • the first paper web 1 is printed by a printing roll 15, carrying a colorant, a skin care agent or other functional chemical in selected pattern.
  • glue is transferred to the first paper web 1 by a glue transfer roll 5 transferring glue to the web 1 in a selected glue pattern.
  • the second paper web 8 is laminated to the first paper web by the lamination roll 10 having a pattern of protuberances corresponding to the glue pattern and driven in register with the glue transfer roll 5.
  • the lamination roll 10 in this embodiment is also acting as a printing roll, such as a flexographic printing device or any optional printing device adapted to print on paper or nonwoven.
  • the combined printing/lamination roll 10 prints a printing pattern on the outside of the laminated multi-ply product 17.
  • this printing pattern is identical to and printed on the second paper web 8 on top of the glue pattern on the first paper web 1 provided by the glue transfer roll 5.
  • the printing pattern provided by the combined printing/lamination roll 10 may be different from the glue pattern as described in connection with the embodiment of Fig. 1 as long as it covers the glue pattern and thus provides a lamination of the plies.
  • the glue pattern will also form a visible printing pattern which can be seen from the outside of the multiply product.
  • a "two- sided" product will be provided. This means that the product will look different from different sides, since from one side more or less only the coloured glue pattern 20 will be visible, while from the opposite side more or less only the identical printing pattern 21 will be visible. This is illustrated in Fig. 4.
  • the first printing pattern provided by the first printing roll 15, for example a decorative figure, is denoted 18.
  • a two-sided product may be desirable in cases where the opposite sides of the product have different properties, for example one soft, smooth and absorbent side and one side for example having a more rough surface adapted for cleaning and/or a surface having a three-dimensional structure suited for wiping viscous fluids.
  • the paper webs 1 and 8 that are laminated can be either smooth but also have a three-dimensional structure provided earlier in the process, for example during forming, dewatering and/or drying of the paper web.
  • a three-dimensional structure may also be provided by embossing the dry paper webs before lamination.
  • the method according to the invention is very lenient to such a pattern, so that this is maintained substantially intact throughout the laminating process.
  • the paper webs 1 and 8 laminated together may be of the same or different type. For example, as explained above, a two-sided product may be provided where different sides of the multiply product have different properties.
  • Another important advantage of the invention is that the paper substantially maintains its strength properties through the process, which in many other lamination processes, in which an embossing and deformation of the paper webs occur in connection with lamination, are decreased. Because of the substantially smooth structure of the laminated multiply product this can be converted into dense rolls or folded products, which means space- and cost saving.
  • the laminated multiply product may also if desired, due to the strong ply bonding provided by the glue spots, be embossed after the lamination process, thereby creating a softer material.
  • a relatively dense embossing pattern having a relatively small embossing depth is used, for example a so called "micro quilted" embossing pattern, so as to not disturb the appearance of the printed pattern. It is also possible to use a macro embossing pattern.
  • Three or more paper plies may of course be laminated with the method described above. Two or more glue stations may therefore be provided, which are driven in register and/or two or more plies may enter the first and/or further press nips.
  • Different kind of paper with different properties with respect to absorption capacity, basis weight, manufacturing technique, fiber composition, chemical additives may be used in the different plies.
  • the method is further suitable to use for paper plies having holes therein, since the main part of the holes will be intact throughout the lamination process and not be filled with glue, which normally is the case when gluing the plies together.

Abstract

L'invention concerne un procédé de production de toile multicouche (17) de matériau flexible, tel que papier et non tissé, comprenant au moins une première (1) et une seconde couche (8) interconnectées par collage selon plusieurs sites discrets de colle (13). La toile est imprimée avec au moins une structure (18;19) en correspondance avec la structure de colle (12). La toile multicouche est produite selon un procédé consistant à amener une première couche (1) en contact avec un rouleau de transfert de colle structurée (5), transférant la colle sur la première couche dans une structure de colle, une seconde couche (8) étant amenée en contact avec le côté sur lequel est appliquée la colle de la première couche (1) dans une pince de presse entre un rouleau de lamination structuré (10) et un rouleau d'impression (7),le rouleau de transfert de colle (5) et le rouleau de lamination (10) étant en correspondance l'un avec l'autre avec des structures correspondantes. Au moins une des couches est imprimée à l'aide d'un rouleau d'impression (15;16) portant un colorant, un agent de soin dermatologique ou un autre produit chimique fonctionnel selon une structure choisie, cette impression étant réalisée en registre avec le transfert de glu alors que le premier et/ou second matériau flexible en forme de toile se trouve sur ce rouleau d'impression (7).
