Definitions

  • the present invention relates to a process for laminating plies of tissue paper according to the preamble of claim 1, and to a laminated tissue paper according to the preamble of claim 10.
  • Embossment patterns are produced by feeding tissue plies through at least one embossing unit. Subsequently; the tissue plies are generally ply bonded to produce, for example, a 2-ply or a 4-ply tissue paper.
  • the creation of bulk by embossing is limited by various factors.
  • the depth of the pattern, the hardness of the backing roll in an embossing unit for steel/rubber embossing, the type of embossing pattern, if union embossing is used and, last but not least, the tissue paper itself are all factors which can limit the bulk that is achievable in a hygiene paper product.
  • EP-A-0,344,056 describes a process and apparatus for producing a multi-ply embossed fibrous sheet. Separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, the embossed webs separated from one another and longitudinally displaced relative to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another.
  • the disclosed process results in a multi-ply sheet with a thickness essentially the same as that embossed with the same pattern and not separated and recombined in a displaced manner after embossing.
  • US 3,668,055 discloses superimposed embossed packaging sheets. A series of sheets of relatively heavy paper or similar matted fibrous materials are embossed and then passed through shorter or longer paths of travel before again being assembled so that their matching mounds and recesses are offset in such a manner that they no longer match.
  • the disclosed method is, however, designed for kraft paper and is not suitable for tissue paper.
  • the object underlying the present invention is to provide a process for laminating plies of tissue paper, as well as a laminated tissue paper, of the above mentioned kind, wherein bulk is increased in an easy manner.
  • At least two plies of tissue as it is used for manufacturing hygiene paper products, for example toilet paper, household towels, or the like, are embossed with one and the same embossing nip. Both plies are provided with substantially the same embossing pattern consisting of embossing protrusions.
  • the protrusions of the ply which is nearest to the embossing roll stack backwards into the indentations (protrusions) of the second ply.
  • the generated bulk of the paper depends on the height of the protrusions, i.e. the embossing depth.
  • the maximum distance D in the displacement direction between an embossing protrusion of a first ply and an embossing protrusion of a second ply, which has been displaced relatively to said first ply is set as a function of the height H of the embossing protrusions and the length L of the embossing protrusions in the displacement direction of the two plies, so that D is equal to the smaller one of the values of 12H and 14L.
  • the embossing displacement can be subsequently fixed by any conventional, well-known ply bonding technique.
  • the resulting laminated tissue paper has an increased thickness, which creates more volume in the product.
  • the embossing protrusions of the respective tissue plies are reliably prevented from nesting, and the recombined tissue paper has an increased volume as compared to the two plies the protrusions of which are in register, before having displaced the plies.
  • the defined distance D in the displacement direction between an embossing protrusion of a first ply and an embossing protrusion of a second ply prevents the unembossed areas on one ply from being pressed down under the effect of gravity by the embossing protrusions of the other ply.
  • the higher bulk gives an improved sensation of bulk softness, a critical feature for the feeling of softness.
  • the increase in thickness moreover creates a textile-like appearance which is a very desirable feature of high quality tissue paper products.
  • the embossing protrusions will extend outwards. This might slightly impair the aesthetic appearance and the haptics of the product. To avoid this, another ply, either unembossed or embossed, can be joined to the laminate. In case an embossed ply is used, the embossing protrusions thereof ought to be directed inwards.
  • Fig. 1 shows a first embodiment of an apparatus for carrying out the process according to the invention.
  • the apparatus serves for embossing and combining four plies 1, 2, 3, 4 of tissue in the form of a fibrous web, and operates as follows.
  • Two plies 1, 2 are combined and fed to a bottom embossing roll 10 by means of which they are embossed in combination.
  • the two plies 1, 2 are embossed with one and the same nip and, therefore, provided with the same embossing pattern consisting of embossing protrusions.
  • the protrusions of the ply 2 which is nearer to the embossing roll 10 stack into the protrusions of the other ply 1.
  • embossed tissue plies 1, 2 are then separated and displaced relatively to one another so that the embossing protrusions are not in register with each other.
  • this displacement or phase difference between plies 1 and 2 is effected by passing ply 1 over a deviating roll 15 so that it travels along a longer path than ply 2.
  • plies 1, 2 are recombined at a merging roll which, in this case, is a design roll 20.
  • a merging roll which, in this case, is a design roll 20.
  • two further plies 3, 4 are fed to a top embossing roll 11 and are also embossed in combination. Afterwards, they are also fed to the design roll 20.
  • a glue application roll 30 is provided for applying glue to the upper one of the plies 3, 4.
  • design roll 20 can also correspond to a further embossing roll to apply a further embossing pattern to all the plies 1 to 4.
  • the plies 3, 4 are fixed to the previously mentioned plies 1, 2 at a marrying roll 40.
  • the resultant 4-ply sheet, comprising the two embossed, relatively displaced plies 1, 2 and the two further plies 3, 4 which are also embossed, is then discharged from the apparatus.
  • FIG. 2 is a modification of the process of Fig. 1.
  • the further plies 3, 4 are also separated and displaced relatively to each other, in a similar manner as in the case of ply 1.
  • the bulk of the plies 3, 4 is increased so that the overall bulk of the resultant 4-ply tissue is even greater than that produced in the apparatus of Figure 1.
  • one of the first plies 1, 2 can also be directed to the glue application roll 30 by means of further deviating rolls 17, 18 and 19. Glue is then applied to ply 1 before ply 1 is recombined with ply 2, to ply bond plies 1 and 2.
  • Figure 4 shows a fourth inventive embodiment in an arrangement wherein plies 1, 2 and 4 are simultaneously fed to the bottom embossing roll 10, while only ply 3 is fed to the top embossing roll 11.
  • the same embossing pattern is applied to plies 1, 2 and 4, while a different pattern may be applied to ply 3.
  • plies 1, 2 and 4 are separated by means of deviating rolls 15 and 17, 18, 19 and 21, respectively, and glue is applied to ply 4 by means of the glue application roll 30.
  • the four plies 1, 2, 3, 4 are then recombined at the design roll 20 and marrying roll 40.
  • Figure 5 shows, as a fifth embodiment, a similar arrangement to that of Fig. 4 wherein, however, ply 1 is directed to the glue application roll 30 by means of deviating rolls 17, 18 and 19, whereas ply 4, after having been embossed together with plies 1 and 2, is fed directly to the design roll 20 by means of deviating rolls 22, 23 and 24.
  • the embossed tissue paper has a base plane, i.e. the plane of the unembossed parts of the paper, and embossing protrusions protruding there from.
  • the height H of the embossing protrusions from the base plane to the top of the protrusion may be measured by means of a so-called UBM measuring method such as disclosed in WO-A-00/63489, which is incorporated herein by reference. According to such a method, a cross section of the paper is measured. The length L of the protrusions is measured in the base plane.
  • base tissue The abbreviations in the column “base tissue” have the following meaning, the base tissues being manufactured by SCA Hygiene Products GmbH, Mannheim, Germany:
  • embossing combination shows which embossing and design rolls were used, the embossing designs being those used by SCA Hygiene Products GmbH, Mannheim, Germany:
  • the embossing patterns falling within the scope of the present invention can be of any conventional design.
  • the embossing protrusions have dimensions ususally up to about 5 mm in the machine and cross machine directions. However, certain embossing patterns can also have dimensions up to about 20 mm in length in the machine direction and about 2 mm in the cross machine direction. Additionally, the embossing protrusions can extend at an angle to the machine direction. The height of the embossing protrusions can be about 1 mm to 2 mm. Naturally, however, the dimensions and shapes of the embossing protrusions are not limited to the examples given and are well known in the art.
  • the plies of the laminated tissue paper and the laminated tissue paper product may be plybonded with mechanical or adhesive plybonding as known in the art.
  • Mechanical plybonding as known in the art can be achieved by application of a high pressure, e.g. in an additional embossing nip.
  • ultrasonic welding for plybonding a method that is explained in the US pending provisional patent application No. 60/341803.
  • the glue can, for example, be added to all the protrusions of one ply or with a structured glue application roller to just some of the protrusions.
  • the paper can also be further embossed in a further embossing nip, for example by giving the paper an embossed spot pattern.
  • a further embossing nip for example by giving the paper an embossed spot pattern.
  • spot protrusions will be covered with glue and will be the part that bonds to the other plies.
