Definitions

  • the present invention relates to improved tissue paper rolls, such as toilet paper, kitchen paper or the like.
  • the invention also refers to a working method for making such improved rolls. State of the art
  • FIG. 1 an example of a prior known art system for the production of rolls of the first type, i.e. wrapped around a tubular core, is shown.
  • the system represented consists of a main line, LP, for the production of rolls and of an auxiliary line, LA, for the production and feeding of cardboard tubular cores.
  • the main LP line suitable for the production of two veils rolls, comprises successively a first unwinder, S1 , a second unwinder, S2, an embossing or printing group, GS, a tubular cardboard cores rewinder, R, an adhesive applier, I, a roller storage tank, AR, and finally a trimmer, T.
  • the auxiliary line LA is constituted by a cores former machine, FT, which produces tubular cores from two or more coils of cardboard strips, SC, of a limited axial length which are spirally wrapped together around a fixed spindle to form the cardboard tubes which are then extracted from the spindle by an elevator E, which raises the tubes so formed to feed them from above into a cores storage tank, AA, usually of a hopper type, from which they pass into a feeder, AL, which feeds them individually in succession, to the cores rewinder R of the main line LP according to the timing defined by the rewinder itself.
  • FT cores former machine
  • the first and second unwinder, S1 , S2 unwind two respective tissue paper coils and feed the embossing or printing group GS with two corresponding tape paper veils of tissue type.
  • the two veils are embossed or printed and coupled by roller assemblies according to known prior art, and then the two-veils tape paper is been fed to the tubular cardboard cores rewinder R.
  • the tubular cardboard cores rewinder R wraps the two-veils tape paper around a tubular core coming from the auxiliary line LA according to known techniques, forming rolls of a determined diameter constituted of a multiplicity of two-veils tissue paper wraps wrapped around a tubular cardboard core.
  • a roll When a roll is completed, it is ejected by the rewinder R and transferred to the adhesive applier I where the outer paper wrap is pasted over the preceding one in order to obstacle the roll unwinding. Subsequently, the roll is transferred to a rolls storage tank AR, which acts as a lung between machines with different productivity, and then feeds the trimmer, T, in which the roll is cut perpendicular to its axis in a plurality of identical small rolls that have the axial length of the finished product (toilet paper, kitchen paper, etc.
  • the systems of the type described above are expensive, and in particular the cores former machines FT have high costs, as well as the paper coils with which the tubular cores are realized but, above all, they create the need to handle raw materials , paper coils and adhesives, which are different from those used for processing the tissue, so they have to be supplied from other sources and stocked in special warehouses.
  • tubular cores create the problem of their disposal when the paper roll is all used: disposal cost, drain clogging if thrown into the toilet, environmental problems related to their production and disposal because a line like the one mentioned, for example, can use over 5 tons of cardboard a day, and this means trees to be cut down and used pipes that end up in the environment.
  • rolls obtained using the above-mentioned technologies, as well as generally all coreless rolls have the structure of a full or substantially full cylinder if the central hole is small or of a paper cylinder with the central hole collapsed and with the first paper layers deformed if the central hole is large.

  • a separating element such as a sheet of different material interposed between two consecutive wraps of the wrapping paper
  • the main purpose of the present invention is to propose a roll of tissue paper belonging to the category of inner core rolls which however does not exhibit the above- mentioned limits and disadvantages of the cardboard core rolls.
  • Another object of the present invention is to propose a roll of tissue paper which has zero or extremely low overall disposal costs.
  • Another object of the present invention is to propose a paper roll made entirely of tissue paper and with a central hole of such size as to allow it to be used with common dispenser supports.
  • Yet another object of the present invention is to propose a paper roll that can be manufactured by means of high productivity or even already existing plants with the only change of a minor part of machinery.
  • Another object of the present invention is to propose a paper roll made using, for the cores formation, only materials already present in the roll production line without the need to introduce and handle different materials, as instead occurs in the case of cardboard cores for which must be handled the latter material, specific adhesives and other related auxiliary materials and equipment.
  • Another object of the present invention is to propose an innovative and

  • the core is made of tissue paper, so the whole roll is made of tissue paper .
  • the core is made of an inner roll consisting of a plurality of tissue paper wraps and the inner roll constitutes the central support around which are wrapped the tissue paper wraps forming the outer wrapped portion of the roll.
  • the inner roll is provided with containment means for which it is not likely to unwind before it is wrapped over the outer rolled tubular portion.

  • the roll of the invention can be used to be associate with most of the commercially available dispenser supports.
  • the inner roll can be similarly used by selecting the containment means of the same with such characteristics as to allow a separation of the paper wraps making it sufficiently easy. Otherwise, it is always possible to dispose the inner roll as simple tissue paper , for example by throwing it directly into the drain if it is a roll of toilet paper or using it to dry or clean if it is a roll of kitchen paper.
  • the core has the shape of a full cylinder with a diameter smaller than the total diameter of the roll.
  • the inner roll provides an amount of additional tissue paper rather relevant with respect to the common cardboard tubular core rolls.
  • the embodiment in which the inner core or roll has a cylindrical tubular shape having an inner diameter greater than or equal to 5 mm and an outer diameter not greater than 90 mm requires that this is constituted of two-veils paper wraps each of the tissue-type, embossed and laminated, and that the inner roll containment means consist of adhesive means applied between the inner face of each paper wrap and the outer face of each paper wrap immediately below.
  • the above-described inner roll structure provides the same a stiffness suitable for its use as a central support core for wrapping the outer rolled tubular portion even if it is formed by a relatively low paper wraps number and then with a very low raw material cost.
