Definitions

  • the present invention relates to the field of cellulose wadding products for sanitary or domestic use and is more particularly an embossing and assembly facility for the manufacture of multiply products.
  • products are produced in rolls generally consisting of at least two plies of cellulose wadding.
  • Cellulose wadding is a sheet of light weight paper, between 10 and 50 g / m 2 , which is obtained on paper machines designed and adjusted to give it properties of mechanical strength, softness and resistance. absorption capacity in relation to the application for which it is intended.
  • the formed sheet is reeled and stored as a semi-finished product.
  • the machines for the manufacture of this type of paper are well known.
  • the semi-finished product is subsequently converted into rolls or size formats adapted to their use.
  • the transformation consists of the assembly of several folds into a multi-ply sheet with a step or no embossing, a step or not of knurling, placing in rolls or in formats and cutting to the commercial dimension.
  • the embossing makes it possible in particular to increase the thickness of the sheet, by modifying its mechanical properties.
  • One or more plies can be embossed before assembly in a pattern composed of discrete or continuous protuberances, so as to impart more volume to the sheet and improve its softness, its ability to absorb liquids and / or its aesthetics.
  • a processing installation generally comprises one or more embossing groups, with possibly an adhesive applicator.
  • an embossing unit is used which comprises a rigid cylinder, etched on the surface in a pattern. relief as desired, and for example a cylinder with a deformable coating, generally made of elastomer.
  • the embossing fold is guided between the two rolls which roll one over the other.
  • the pressure exerted by the deformable cylinder on the fold causes a deformation more or less pronounced of the latter which marries the relief of the engraved cylinder.
  • the embossing units are provided with means for driving the cylinders in rotation, as well as for adjusting their spacing. See for example the document WO 98/53985 .
  • the installation for producing this type of sheet comprises two distinct embossing groups arranged so that all or part of the peaks of the protuberances of the two engraved cylinders come into contact through the two folds which are guided between them.
  • Another method of assembling folds forming a sheet is known as "nested".
  • the protuberances of a fold are nested between those of the fold vis-à-vis.
  • the two plies are waffled separately on two separate embossing groups; a fold is detached from the engraved cylinder on which it has been embossed and then applied to the other fold still resting on the cylinder by which it has itself been embossed. Glue was previously applied to the top of the protuberances of this last fold.
  • the combination of this fold with the other is done by means of a so-called marrying cylinder, which exerts a pressure on the assembly allowing the connection of the two folds.
  • a first known installation allowing the association of folds is schematically shown on the figure 1 .
  • the installation comprises a smooth cylinder 1A1 and wheels 1M1 and 1M2.
  • the pressure of the wheels on the combined plies may be sufficient to bind them mechanically without adhesive, but the pressure exerted must be particularly strong. In this case, the imprint wheels inevitably remain; moreover, it can not be homogeneously distributed, generating an irregular "rendering".
  • the figure 2 schematically shows a conventional plant for producing a tip - to - tip product where a first embossing group 2C1-2A1 (rubber - steel with protuberances) is arranged to cooperate with a second equivalent group 2C2 - 2A2.
  • a first embossing group 2C1-2A1 rubber - steel with protuberances
  • the figure 3 shows another solution using a single embossing group comprising a deformable cylinder 3C1 elastomer and a rigid cylinder with protuberances (steel) 3A1 associated with a 3M marrying cylinder.
  • the installation would make it possible to manufacture a sheet with an embossed or unembossed fold, depending on whether the rubber roll 3C1 is bearing or not against the steel roll 3A1.
  • marking can not be avoided when passing through the connection zone. If the roll 3M is soft, the multiply sheet is waffled, which is not the desired solution; if the cylinder is hard, one can not avoid the marking generated by the protuberances of the cylinder 3A1.
  • the figure 4 shows an installation for the manufacture of a "nested" product.
  • the installation consists of two embossing groups 4C1-4A1 and 4C2-4A2.
  • the two plies are embossed separately between the cylinders 4C1-4A1 and 4C2-4A2, respectively, and then they are associated by means of a 4M marrying cylinder.
  • the two plies are not waffled. This provision thus allows, as in the previous proposals, to manufacture one of the embossed or non-embossed plies.
  • the marking of the sheet at the passage between the marrying roll 4M and the associated steel cylinder 4A1 can not be avoided, since the roll 4M necessarily supports the sheet against the protuberances of the roll 4A1 to generate the combination of folds.
  • the plaintiff has set itself the objective of producing an installation that would make it possible to manufacture a conventional embossed product or a smooth product without marking, with the associated plies. Another objective is to achieve an installation that would easily switch from one mode of production to another.
  • a first embossing group with a rigid cylinder provided with embossing protrusions and a cylinder with deformable coating capable of being pressed against the rigid cylinder for embossing a first band of cellulose wadding by passing the first band between the rigid cylinder and the deformable-coated cylinder, and a marrying cylinder which can be applied against the rigid cylinder so as to marry the first band to a second band, the two strips being guided between the marrying cylinder and the rigid cylinder of the first embossing group.
  • This installation is characterized by the fact that it comprises an additional marrying cylinder which can be placed in abutment against the marrying cylinder so as to allow the assembly of the two cellulose wadding strips, by passing between the marrying cylinder and the cylinder additional marryer, the assembly being without marking when the first band passes around the first rigid cylinder without support of the deformable coating cylinder against the rigid cylinder.
  • the marrying cylinder is disposed between the rigid cylinder of the first embossing unit and the additional marrying cylinder and is movable between a first position of connection between the rigid cylinder and the marrying cylinder and a second connecting position. between the marrying cylinder and the additional marrying cylinder.
  • the installation comprises a sizing unit for applying glue to the first cellulose wadding.
  • a glue applicator cylinder for applying the glue to the surface of the first strip when it is placed on the rigid cylinder.
  • the glue applicator device comprises a glue spraying means between the two plies.
  • the installation comprises a second embossing group for embossing the second cellulose wadding.
  • the invention particularly relates to a method for producing a bonded and unlabelled sheet from two wadding strips, comprising passing a first band of cellulose wadding in the first embossing group of the plant without it being embossed, then passage of this first band with a second band of cellulose wadding between the marrying cylinder and the additional marrying cylinder.
  • FIG. 5 an installation where the majority of the components correspond to the installation of the figure 4 .
  • It comprises a first embossing group comprising a rigid cylinder 5A1, made of etched steel for example, cooperating with a deformable coating cylinder 5C1.
  • the etching pattern may be arbitrary and include so-called embossing protuberances.
  • the second embossing group also comprises an engraved rigid cylinder 5A2 cooperating with a deformable coating cylinder 5C2.
  • the patterns of the two engravings on the rigid cylinders are compatible with each other, so that the folds that are derived from the two embossing groups can be found in "nested" configuration.
  • the protuberances of a first fold are placed between the protuberances of the second fold.
  • the two folds fit one into the other.
  • a sizing group schematized by the elements BTA applies glue on the protuberances of the first band 10 in place on the cylinder 5A1.
  • the installation comprises a 5M matched parallel shaft to that of the rigid cylinder 5A1. This part of the installation corresponds to that of the prior art illustrated on the figure 4 .
  • an additional 5M2 marrying cylinder was added to this installation an additional 5M2 marrying cylinder.
  • This cylinder preferably has an axis parallel to that of the marrying cylinder 5M.
  • the installation comprises a third embossing group and a marrying cylinder.
  • the additional marrying cylinder 5M2 according to one embodiment is the marrying cylinder of the third embossing group which has not been shown.
  • the two deformable rolls 5C1 and 5C2 are placed in position by which the folds 10 and 20 respectively are entrained in the nip intervals that they form with their engraved rollers 5A1 and 5A2. respective.
  • the marrying cylinder 5M bears against the cylinder 5A1.
  • the first ply 10 is embossed by passing through the nip between the rolls 5C1 and 5A1.
  • Glue is deposited by the gluing unit BTA on the tops of the protuberances created by the embossing of the first fold 10 on the cylinder 5A1.
  • the second ply 20 is embossed while passing between the rolls 5A2 and 5C2, then is detached from the cylinder 5A2 to join the fold 10 again on the cylinder 5A1.
  • the marrying roll 5M applies a pressure on the sheet formed by the two folds 10 and 20, thus ensuring their connection to the cylinder 5A1.
  • the sheet is then guided to a reeling station of the sheet and cutting the roll into individual rolls.
  • the two cylinders 5C1 and 5C2 are separated from their associated embossing cylinder, respectively 5A1 and 5A2, so that the folds 10 and 20 are not embossed while passing around the rolls 5A1 and 5A2.
  • the marrying roll 5M is moved so that it no longer exerts pressure on the cylinder 5A1, but it comes to press the sheet formed by the two folds 10 and 20 against the additional marrying cylinder 5M2 causing the association said folds.
  • the two cylinders 5M and 5M2 are smooth, the product that comes out is perfectly smooth too, while being perfectly associated, and in particular optimizing its softness.
  • the sizing of the sheet is limited to the surface of the protuberances on the cylinder 5A1.
  • the rigidity is not increased by passing from an embossed product to a smooth product.
  • the method according to the invention for the assembly of a sheet is also applicable to an installation using a single embossing group or a tip-to-tip configuration, as well as any installation of the prior art.
