Definitions

  • the present invention relates to the field of rolls of tissue paper or other similar material such as a nonwoven. It relates in particular to the field of products for sanitary and / or domestic use such as wiping rolls, towels or toilet paper.
  • Tissue paper means a paper whose characteristics are defined by the European standard EN 12625-1 .
  • a roll is formed by winding-a continuous sheet which is composed of one or more folds of paper.
  • the sheet is optionally precut in consecutive coupons in the direction of the winding, and is wound, preferably about an axis or a pin that can support or not a mandrel; the roll can thus comprise a central mandrel or not.
  • the roll is unwound, either from its outer surface in the direction of the winding perpendicular to its axis, it is called tangential unwinding, or from the inside from the center in its axial direction. In the latter case, it is said that the roll is centrally rewind.
  • the present invention relates to rollers having a central, center-fed, and tangential-winding roll.
  • the roll When the roll is for a center-feed type application, it may include a mandrel.
  • the mandrel is a cardboard cylinder that extends over the width of the roll. It is generally formed of a cardboard strip wound helically spiral. In this case, it must first be extracted when the roller is put into service.
  • the mandrel can be designed so that it can be torn off when its edge is pulled at one end of the spiral cardboard spiral that forms it.
  • this solution is not always satisfactory, because the extraction of the mandrel is sometimes difficult if the fracture zone or areas are poorly formed.
  • it can cause the first roll sheets that become difficult to use. The first turns of the sheet being most often glued to the mandrel, they are unfit for any use and are a waste.
  • This type of mandrel is expensive to produce, since it is generally composed of two or more bonded layers of cardboard and is associated with an adhesive "hook" of the first turn of the roll. It is no longer useful once removed, and becomes a waste.
  • the sheet is cut in line in the direction of the latter or longitudinal, before winding on the spindle, from a sheet of large width, in as many strips as individual rolls to obtain.
  • the mother sheet is wound directly on a pin, also without the interposition of a mandrel.
  • the initial sheet which is large in width, is first rolled up to form a single coil with the final diameter of the individual roll, called "log" in the field. After training, the log is extracted from the spindle and cut into individual rolls.
  • the sheet whether cellulose wadding, creped dry or wet, dry paper or a nonwoven, has some elasticity. Because of the internal stresses of the roll, due for example to the clamping of the sheet on the spindle during the winding and / or the tension of the sheet that generates the unwinding / winding operation by the machine, it can not be avoided normally. reducing the diameter of the central hole by collapsing or collapsing at the center of the first turns after the pin has been removed. This collapse occurs, for example, after extraction of the spindle or at the time of cutting log, the pressure exerted by the saw or during packaging and overpacking operations.
  • the primer is a tight, helical, low-pitched torch that is not conducive to easy extraction.
  • the diameter of the central hole is larger, it is necessary to associate the first turns between them.
  • a bonding agent that is deposited directly on the sheet or indirectly via the spindle on the winding rolls, by a suitable system, at the time of winding of the first turns on the spindle. Any other principle of association of the first turns with each other, by a mechanical process in particular, is applicable. We thus consolidate these first turns which together withstand the efforts of internal constraints.
  • the Applicant has developed a mandrel-free mandrel-type roller comprising a central unwinding primer along its axis, intended to facilitate the gripping of the innermost turns of the roller.
  • This technique is described in patent applications FR 2 869 891 and EP 1 636 123 . This is a specific solution to the problem of the collapse of the central hole of rolls without mandrel.
  • the present invention provides a different and inventive solution to this same problem and applies not only to the so-called center-fed rollers, but also to the tangential unwinding rollers.
  • the present invention relates to a roll of paper, especially tissue paper, comprising a central hole along its winding axis with a cylindrical reinforcing element on which the paper is wound and characterized in that said reinforcing element comprises at least one ring integral with the innermost turn of the roll, the ring being of width less than the width of the roll and provided with a means for extracting the ring by traction substantially along the axis of the roll .
  • the ring or rings allow support of the hole from its manufacture, and until the end use, with little additional material vis-à-vis a roll without mandrel and without special reinforcement.
  • the ring comprises at least one slot allowing, from the outer edge of the ring, to fold the material constituting the ring towards the axis of the roll and thus to provide a tongue forming said extraction means.
  • the slot follows the curvature of the ring and is in particular an arc.
  • the slot is preferably perpendicular to the axis of the ring.
  • the extraction means is formed of the inwardly folded arcuate portion extending from the axial edge of the ring.
  • the slot is axial.
  • the slot extends from one edge of the ring over a portion of the width of the ring.
  • the extraction means is formed of the portion of the ring folded towards the axis of the roll.
  • the roll has two or more slots for increasing the number of gripping means forming the extraction means.
  • the ring is preferably made of cardboard, flush with or near one of the sides of the roll.
  • the ring comprises at least two layers with an outer layer in contact with the sheet of paper and an inner layer towards the axis of the roll, with a means for extracting the inner layer.
  • the ring is advantageously corrugated with a corrugated layer between two non-corrugated layers or formed of folds of different grammages including higher grammage for radially internal folds.
  • the outer layer and the inner layer are glued to each other, a part of the inner layer in contact with the outer layer not being bonded to the outer layer and forming the extraction means of the inner layer.
  • the ring comprises at least two layers with an outer layer in contact with the sheet of paper and an inner layer towards the axis of the roll, the two layers being formed of helical turns, the turns of the inner layer partly overlapping and not being bound in the overlap area.
  • the turns of the outer layer and the turns of the inner layer are wound at the same winding angle and the turns of the inner layer have a width greater than that of the turns of the outer layer of to create said overlap.
  • the turns of the outer layer are contiguous or substantially joined; they may not be perfectly joined.
  • the ring has a zone deformed by displacement towards the axis of the roller so as to form a spoiler.

  • This dimension reduces the cost of the material to a chuck solution over the entire width of the roll, while being sufficient to prevent collapse of the central hole.
  • At least the ring has a thickness of between 0.1 and 4 mm. Depending on the material used, the thickness of the wall of the ring is determined to ensure sufficient resistance to crushing.
  • a second ring is disposed in the central hole near the other edge. It can be maintained without sticking in the hole to the extent that it does not participate in the extraction of the sheet. It can also in the case of use with tangential unwinding forming a support bearing on an axis of the distributor on which the roller is installed.
  • the invention also relates to the use of a roll in a center-fed paper dispensing system.
  • a method of manufacturing a roll according to the invention comprises placing on a spindle rings arranged for, after transverse cutting forming two of said rings, to provide an extraction means on each of said rings, the winding of a large sheet on the spindle, the extraction of the spindle and the log section obtained across said rings so as to obtain rollers with said rings.
  • the rings are temporarily fixed in rotation and in translation on the spindle, the time to allow the winding of the sheet without sliding.
  • the rings are fixed temporarily on the spindle by mechanical means, in particular by crimping.
  • Another method of manufacture includes placing rings in the central hole in the roll after the roll has been wound.
