Definitions

  • the present invention relates to an apparatus for pasting two or more plies for manufacturing tissue products.
  • embossing is frequently used to modify the softness and absorption features of the end product.
  • the products are manufactured by bonding multiple plies of paper and there are many different embossing and coupling systems.
  • two or more paper plies are embossed separately and then mutually bonded by means of tip-to-tip bonding systems or nested bonding systems, so-called random nesting or "DERL” systems, and the like.
  • two plies are each embossed between an embossing roller, provided with protrusions or tips arranged according to a repetitive pattern, and a presser roller, generally covered with yielding material, such as rubber or equivalent.
  • the two plies are bonded by lamination between the two mutually opposite embossing rollers, which are synchronized so that in the lamination groove between the two rollers the tips of one roller are located at the tips of the other roller.
  • the distance between the rollers is such as to cause the lamination of the plies between the mutually opposite tips.
  • an adhesive is applied to one of the two plies at the regions in relief generated by the embossing.
  • the plies are embossed separately in a manner similar to what has been described above and are mutually coupled so that the tips of one ply are interleaved with respect to the tips of the other ply.
  • the two embossing rollers are not pressed against each other in the groove between them, and the two plies are mutually bonded by lamination between one of the two embossing rollers and a bonding roller.
  • Devices have been proposed for providing both an embossing of a nested type and an embossing of the tip-to-tip type by modifying in each instance the configuration of the components of the device, converting an actual tip-to-tip embossing assembly into an actual nested embossing assembly.
  • WO2005/033408 discloses an embossing device for obtaining a sheet comprising two folds.
  • An upper fold comprises first areas forming cells with first cavities; the cells are surrounded by second areas with second cavities; the first areas are elevated on the outer surface in relation to the second areas.
  • the aim of the present invention is to provide a new pasting and embossing system which allows to obtain a product which is improved in terms of softness and handfeel.
  • An object of the invention is to provide a pasting system which allows to use a reduced amount of paste.
  • Another object of the invention is to provide a system which allows to provide any type of pattern on the product.
  • an apparatus for pasting two or more plies for providing tissue-type products comprising at least one first embossing roller which cooperates with at least one second embossing roller, characterized in that said first embossing roller comprises a plurality of tips alternated with a plurality of continuous protrusions, said second roller comprising a plurality of tips alternated with a plurality of continuous protrusions, the arrangement of the tips and of the continuous protrusions of said first roller being reproduced identically and mirror-symmetrically on said second roller.
  • the apparatus according to the invention comprises at least one pair of embossing rollers, a first roller 2 and a second roller 3.
  • each roller has a plurality of tips 4 which are alternated with a plurality of continuous protrusions 5 and with regions or compartments 6 without tips or continuous protrusions.
  • the first roller 2 has a regular pattern which is constituted by a series of tips 4 spaced by a series of protrusions 5.
  • the depth P of the incision is preferably comprised between 0.3 and 2.5 mm.
  • the arrangement of the tips 4 and of the continuous protrusions 5 of the first roller 2 is identically and mirror-symmetrically reproduced on the second roller 3.
  • the pasting areas are constituted only by the regions 7 that correspond to the presence of a tip 4 on the other roller.
  • mirror-symmetrical pattern here means that the second roller has a pattern that correspond to the first roller but in which the tips are replaced by continuous protrusions and the continuous protrusions are replaced by tips.
  • the apparatus comprises at least one pair of embossing rollers, a first roller 102 and a second roller 103.
  • each roller has a plurality of tips 104, which are separated by a plurality of recesses 105, which are arranged on raised regions 107 which are spaced by regions or compartments 106 without tips.
  • the depth P of the incision of the tips 104 is comprised preferably between approximately 0.15 mm and approximately 0.4 mm.
  • the incision depth S of the raised regions is comprised preferably between approximately 1 mm and approximately 2.5 mm.
  • the pasting of the plies is performed, if the rollers are provided with identical patterns, only at the regions 108 of contact of the tips 104 of the two rollers, since one of the plies to be joined is spread previously with paste, or laminated, only on the protrusions generated by the embossing process.
  • the bonding of the plies is provided on the protrusions that meet randomly, as shown schematically in Figures 4-7 .
  • the invention achieves the intended aim and objects, an apparatus having been provided which is capable of pasting two or more plies with a reduced consumption of paste, thus obtaining a product with superior functional characteristics which is cheaper also from a production standpoint.
  • the pasting system according to the present invention also allows to increase the thickness of the embossed paper.
