  • the ply V1 is fed for an angle of approximately 180° around the roller 5.
  • Positioned around the roller 5 is a device 7 to distribute the powders of superabsorbent material.
  • the device 7 forms a storage chamber, in which the particles of superabsorbent material, fed by means of a metering device of known type and not shown, are held in suspension in a flow of air.
  • Suction through the perforated casing of the roller 5 and through the ply V1 along the extension of the suction sector 5A of said roller 5 causes attraction of the particles or powders of superabsorbent material suspended in the gaseous flow towards and against the outward facing surface (that is, not in contact with the roller 5) of the ply V1.
  • the particles are partly retained through the effect of penetration (caused by suction) between the fibers forming the ply and partly through the effect of any glue previously applied to said surface of the ply V1 by a gluing unit 9, disposed upstream of the area to distribute and apply the particles of superabsorbent material by means of applicators comprising, in this example, the device 7 and the suction roller 5.
  • the gluing unit 9 has a glue applicator roller 11 which cooperates with a counter roller 13.
  • the ply V1 is fed into the nip between the rollers 11 and 13 and receives, on the face thereof facing the glue dispensing roller 11 , an adequate quantity of glue to cause at least partial adhesion of the granular particles of superabsorbent product.
  • the roller 11 may be a patterned roller, or may receive the glue according to a pattern produced on a distributor roller 15 which picks up the glue from a tank and distributes it on the cylindrical surface of the roller 11.

  • strips or bands of ply V1 can, for example, be produced devoid of particles or powders of superabsorbent material.
  • These bands or strips devoid of superabsorbent material can coincide with the shear planes along which the rolls or logs formed by winding of the plies V1 , V2, V3 are subsequently cut, as explained in more detail hereunder, to form the finished rolls or folded products destined for distribution and consumption.
  • the powders or granular particles of superabsorbent material are not distributed in those areas in which the cutting blade acts to divide the web material formed by joining of the plies V1 , V2, V3.
  • the absence of these powders in the cutting area reduces wear of the blade and possible dispersion of particles into the surrounding environment, with evident savings in the costs of powders and absence of environmental risks.
  • the pressure exerted between the rollers 5 and 6 causes reciprocal adhesion of the plies V1 and V2, thanks to the glue applied by means of the dispenser 9.
  • the combination formed by the plies V1 and V2 and by the superabsorbent material in powder distributed therebetween is fed along a feed path to the embossing-laminating unit 3.
  • the combination V1 , V2 with the superabsorbent material interposed is fed around a pressure roller 17, optionally coated in rubber or another yielding material, cooperating with a first embossing roller 19, which is provided on the surface thereof with protuberances of adequate shape, advantageously protuberances with a truncated pyramidal shape, distributed according to an adequate pattern on the circumferential extension of said roller 19.
  • the embossing roller 19 forms a lamination nip with a second embossing roller 21 which cooperates with a pressure roller 23 equivalent to the roller 17.
  • a third ply V3 is fed around the pressure roller 23 and then into the nip formed between said roller 23 and the second embossing roller 21.
  • the ply V3 is embossed by the protuberances provided on the embossing roller 21 , while the combination formed by the plies V1 and V2 with the superabsorbent material interposed is embossed between the pressure roller 17 and the first embossing roller 19.
  • the protuberances of the two rollers 19 and 21 can coincide at least partly and the interdistance between the rollers can be such as to cause depression, that is, lamination, of the plies V1 , V2 and V3 between protuberances corresponding with one another of the rollers 19 and 21.
  • a "point-to-point" embossed product is obtained. Reciprocal adhesion of the unit formed by the plies V1 and V2 and by the ply V3 is guaranteed by applying a glue to the protuberances formed on the ply V3 by the points or protuberances of the embossing roller 21.
  • This glue is applied by a glue dispenser 24 conceptually analogous to the glue dispenser 9 described previously.
  • an embossing-laminating unit of the "nested" type can be used (as shown in the diagram).
  • the two embossing rollers 19, 21 have an interdistance and/or reciprocal phasing between the protuberances to ensure there is no pressure between the embossing rollers in the nip defined thereby.
  • the plies V1, V2 and V3 embossed as described above pass through the nip formed by the rollers 19 and 21 and are laminated together in a lamination area formed between the second embossing roller 21 and a laminating roller 27 disposed downstream of the nip between the rollers 19, 21. In this case, a nested product is obtained. Reciprocal adhesion between the combination of plies V1, V2 with the superabsorbent material interposed and the ply V3 is again guaranteed by the glue applied by the dispensing unit 25.
  • embossing laminating unit 3 The configurations, both point-to-point and nested, of the embossing laminating unit 3 are known and do not require more detailed descriptions. It is also known that the embossing-laminating device 3 can have an adjustable configuration and thus be able to operate alternatively in point-to-point or nested mode.
  • the glue dispenser 9 can be replaced by a "lotion applicator", that is, a device capable of applying products other than glue, for example a softening lotion.
  • Lotion applicators are known and already used conventionally for application to single- or multi-ply paper materials, such as in the production of cleansing wipes.
  • the path of the ply V1 can be the one indicated in Figure 1 to receive the superabsorbent material, or alternatively said ply can by-pass the applicator means of the superabsorbent material and be fed by the counter roller 13 directly around the tensioning unit 14 and from here to the embossing- laminating unit 3.
  • This alternative path can be taken when the lotion applicator which replaces the glue dispensing unit 9 applies a lotion and therefore superabsorbent powders are not added to the product obtained.
  • the system configured in this way is a dual system which can be used to produce products of different types.
  • Figure 2 schematically represents a cross section, greatly enlarged, of a portion of a multi-ply product obtained with the present invention and indicated as a whole with N. It is observed in the schematic section in Figure 2 that the plies V1 and V2 define an intermediate area or interface in which the superabsorbent material, indicated with S, is contained. In substance, a layer containing superabsorbent powders, which may be continuous or discontinuous, is formed between the plies V1 and V2. These can also be applied in combination with other types of products or additives, such as fillers or the like.

  • the glue C is applied between these protuberances to reciprocally join the ply V3 to the combination of plies V1 , V2.
  • Figure 3 shows, again schematically and greatly enlarged, the cross section of a multi-ply article or product, again indicated with N, obtained with a configuration of the embossing-laminating unit 3 of the nested type.
  • the same numbers indicate parts identical or equivalent to those in Figure 2. It can be observed in this case that the protuberances P1 are intercalated between the protuberances P3 with a nested arrangement.
