Definitions

  • the present invention relates to systems and methods for converting paper, more specifically tissue paper, with which rolls of toilet paper, kitchen towel, paper handkerchiefs, paper napkins and the like are produced.
  • a ply of cellulose fibers is normally formed with a dry or - more frequently - wet technique.
  • the ply is obtained by distributing a pulp of cellulose fibers on a forming screen and then gradually draining the water to obtain a ply of sufficient consistency, which is dried in a suitable way, using a Yankee drum, a TAD system or the like.
  • the dried ply is then wound in reels of large diameter. These reels are subsequently converted, using converting lines, into the finished product.
  • one or more reels of cellulose ply are unwound to feed the continuous web material to converting machines that produce finished products in the form of rolls, packets of handkerchiefs, packets of napkins or the like.
  • composition of the ply of cellulose fibers changes as a function of the final use for which the product produced with the ply of cellulose fibers is intended.
  • a certain quantity of one or more wet strength resins is added to the pulp of cellulose fibers with which the ply is formed; these are resins that give the paper ply at least temporary mechanical strength when wet. This allows said type of paper to be used to clean and dry washable surfaces, for culinary uses and the like, or also as paper sheets replacing conventional cloth towels.
  • wet strength resins for these uses are described in the following United States patents: 6,852,197 ; 6,702,923 ; 6,423 . 179 ; 6,207,013 ; 6,149,769 ; 6,059,928 ; 5,760,212 ; 5,264,082 ; 5,138,002 ; 4,981,557 .
  • the entire ply produced in the continuous machine has substantially the same composition and the same wet strength characteristics.
  • a system is used to produce plies of cellulose fibers in which the pulp is fed continuously onto a felt or cloth through one or more headboxes.
  • An example of a headbox for this use is described in the patent USA n. 5,560,807 .
  • wet strength is not desired, but is instead a disadvantage.
  • the ply of cellulose fibers must disintegrate upon contact with water to allow easy disposal in waste water systems, preventing pipes from clogging and facilitating decomposition in septic tanks and purification plants.
  • wet strength resins are not added to the cellulose pulp with which the ply of tissue paper is produced, or only a minimum quantity is added.
  • US-A-4,512,529 discloses a winding machine and method, wherein a plurality of individual slides are provided, each of which can be selectively arranged in a desired position along a guide.
  • a winding core is supported by a pair receiver devices or tail stocks supported by corresponding pairs of pivoting arms, carried by a corresponding pair of said slides.
  • the slides can be connected to one or more motors for driving the corresponding receiver devices. The position and number of motors is selected according to the quality and properties of the web material to be wound on the core, such that this prior art machine is suitable for winding rollers of web materials of different kinds and properties.
  • an object of a possible embodiment of the present invention is to provide a production method or process that allows greater flexibility to be obtained, or products intended for different uses to be produced even simultaneously on the same line for converting a web material and preferably a cellulose material typically in the form of a web or ply. This object is achieved with a method according to claim 1.
  • Cellulose material is intended, in general, as a semi-finished material obtained by depositing one or more layers containing cellulose fibers.
  • the invention relates in particular to a method for processing or converting a ply or a plurality of plies of tissue paper obtained by a wet process, i.e. in which the ply containing cellulose fibers is obtained from an aqueous suspension of cellulose fibers and any other components, additives, fillers, or the like required.
  • the present invention can also be applied to "dry" production, converting or manufacturing processes of plies, layers or sheets of paper, i.e. obtained using the air-laid technique, in which the cellulose fibers are deposited to form a ply, subsequently consolidated in a suitable manner, without being carried in an aqueous suspension.
  • an object of one embodiment of the present invention is to provide a system or line for converting tissue paper or other cellulose material, which is more flexible, or which allows even simultaneous production of products intended for different uses.
  • a system achieving this object is defined in claim 18.
  • an object of an embodiment of the invention is to provide a method or a production system or line that allows the production of mixed packs containing products intended for different uses, such as kitchen towel and toilet paper.
  • the tissue paper can be composed of one, two or more plies that are joined together in a known manner, such as by ply bonding, embossing, gluing or the like, or by a combination of these techniques.
  • the two or more plies can be fed from the same reel on which two or more plies are wound, or from different reels.
  • the invention relates to a method for simultaneously producing rolls of wound web material having different characteristics to one another, comprising the steps of:
  • the two or more web materials differ by one functional characteristic, and can be wound simultaneously in a winding cradle of a surface or peripheral rewinder, even without a central winding core.
  • Rewinding machines of this type are known to those skilled in the art.
  • two or more windings of web materials will form simultaneously and in axial alignment in the winding cradle.
  • the method provides that the first and the second web material are wound simultaneously on common winding cores, forming logs each comprising: a winding core; a length of said first web material wound in a first portion of the axial extension of said core; and a length of said second web material wound in a second portion of the axial extension of said core.
  • the logs thus configured are cut to form first rolls of a first web material and second rolls of a second web material.
  • the first and second rolls are fed to a common packaging machine, which forms packs comprising at least one of said first rolls and at least one of said second rolls.
  • the reels To allow the paths of the web material to be arranged close to one another, it is advantageous for the reels to feed the web materials in the various paths to be unwound in separate unwinders, staggered along the extension of the converting line. However, it would also be possible for more than one reel to be disposed in the same unwinder aligned axially with one another.
  • the web materials fed in the various paths of the converting line can advantageously differ by at least one technical-functional characteristic.
  • tissue paper for example, a preferred embodiment of the invention provides for feeding web materials with different wet strengths, such as web materials with or without wet strength resins. This allows rolls of kitchen towel (with resins or other wet strength agents) and rolls of toilet paper (without or with small quantities of wet strength resins) to be produced in parallel and simultaneously.
  • the two or more web materials could differ by other characteristics, such as aesthetic characteristics, instead of or in addition to the technical-functional differences.
  • the web materials can be subjected to the same process, or processes at least in part different for the two paths.
  • one or more of the following processes can be provided: embossing, printing, mechanical joining (ply-bonding).
  • embossing in particular, the two or more web materials can be subjected to embossings that differ in pattern, density, engraving depth and/or other characteristics, also as a function of the degree of absorption, softness and depth that the finished material must have.
  • Embossing can take place in distinct embossers for the two or more paths, or in the same embosser, if necessary provided with sector rollers, i.e. divided into different areas for the various paths. It would also be possible to arrange an embosser common to the various paths of the different web materials, and further individual embossers for the individual paths.
  • the web materials can each be composed of a single ply or of two or more plies.
  • the web materials can all have the same number of plies, for example two or three plies, joined to one another with one of the techniques known to those skilled in the art.
  • three plies can be used for one of the web materials and two plies for the other web material.
  • multi-ply reels can be used, i.e. on which two or more plies are wound, which are then preferably unwound and fed along coinciding or even partially different trajectories, for example to emboss two plies along the same path using two distinct embossing rollers of an embossing-laminating unit, in which they are then joined and sent to the rewinder.
  • two or more plies forming the same web material can be fed from two or more separate reels, such as two plies from two single-ply reels, or three plies from three single-ply reels or also from one single-ply reel and one two-ply reel.
  • the invention relates to a system for converting tissue paper or other cellulose web material, comprising at least two adjacent paths for a first web material and for a second web material towards a rewinder.
  • the rewinder is preferably disposed and controlled to produce, in parallel and adjacent to one another, windings formed of said first and of said second web material.
  • the rewinder comprises an inserter of winding cores, and the first and second web material are wound simultaneously on common winding cores, forming logs each comprising: a winding core; a length of said first web material wound in a first portion of the axial extension of said core; and a length of said second web material wound in a second portion of the axial extension of said core.
  • the present invention relates to a pack of tissue paper products, comprising at least two products with different functional characteristics.
  • the term functional characteristic is intended as a characteristic that influences the mode of use or properties of the product, including aesthetic properties.
  • Functional characteristics in general can include: the form of the product (e.g. a product wound in a roll or a folded product); or the greater or lesser wet strength and therefore the presence or absence, or greater or lesser quantity, of wet strength agents; or the presence or absence of printed patterns or the presence of different printed patterns; the presence or absence of embossing, or the different shape of embossing; or yet again the different dimension of the products, etc.
  • Products that differ from one another through a combination of functional characteristics can also be included.
  • the pack comprises two types of cellulose products, preferably made of tissue paper, wound in a roll.
  • a first product is constituted by rolls of toilet paper and a second product is constituted by rolls of kitchen towel.
  • the two products differ above all by the different dimension, i.e. the different axial length of the rolls.
  • the rolls of toilet paper will have an axial length equivalent to half that of the rolls of kitchen towel.
  • the two types of roll will preferably also differ by further functional characteristics such as: the presence of resins or other wet strength agents in the rolls of kitchen towel and the absence (or presence in substantially lesser quantities) of these agents in the toilet paper; possible differences in embossing; possible differences in printed patterns.
  • the ratio between number of rolls of toilet paper and number of rolls of kitchen towel will take into account, in addition to packaging needs, also the different consumption of these products in an average family. It has been found that consumption of rolls of toilet paper is typically higher than consumption of rolls of kitchen towel.
  • the pack can contain two rolls of kitchen towel and four rolls of toilet paper, or six rolls of toilet paper. Larger packs can have a multiple number of rolls of the two types of product.
  • Figures 1 and 2 show a side view and a plan view of a part of a possible tissue paper converting line according to the invention. More specifically, Figure 1 schematically shows the unwinders, an embossing-laminating unit and a rewinder, while Figure 2 schematically shows, besides the aforesaid elements, also a cutting machine positioned downstream of the rewinder.
  • the line comprises a first pair of unwinders 1, 3 in which there are disposed two reels indicated with B A1 , B A2 respectively.
  • the first reel B A1 dispenses a first ply V A1 along a first feed path towards a rewinder 5 to form, together with a second ply V A2 fed from the second reel B A2 , a first web material N 1 .
  • the reel B B1 dispenses a ply V B1 along a second feed path, to form, with a ply V B2 dispensed by the second reel B B2 , a second web material N 2 fed, in parallel to the web material N 1 , to the rewinder 5 along a second feed path adjacent to the first feed path of the web material N 1 .
  • the rewinder can advantageously be a peripheral or surface rewinder, comprising three winding rollers 10, 12, 14, to which winding cores A are fed using a feeder 13, provided with a core inserter, towards the winding area formed of the three rollers 10, 12, 14.
  • the number 15 schematically indicates a cutting machine that cuts the logs formed by winding the web materials N 1 and N 2 fed simultaneously and in parallel to the rewinder 5 into rolls.
  • the shape of the logs L formed by the rewinder 5 will be described in greater detail hereunder with reference to Figure 6 .
  • an embossing-laminating unit 17 which, in the example illustrated, is configured as a tip-to-tip embosser.
  • embossers of a type known per se, comprise a pair of embossing rollers 19, 21 cooperating with respective pressure rollers 23, 25 to separately emboss the plies fed from the reels.
  • the number 27 indicates a glue applicator unit.
  • the two embossing rollers 19 and 21 are divided into two sectors indicated (for the roller 19) with 19A and 19B respectively.
  • the two sectors 19A, 19B have a width substantially the same as the width of the plies V A1 , V A2 and V B1 , V B2 respectively.
  • the two rollers 19, 21 have cylindrical surfaces provided with protuberances which can have different patterns in the sections or sectors 19A, 19B to obtain downstream of the embossing-laminating unit 17 web materials N 1 , N 2 with different embossing patterns.
  • embossing patterns can differ from one another through a different pattern of the engravings on the sectors 19A, 19B, a different density, a different height, or any other characteristic that can distinguish the surface shape of the two sectors, both for the cylinder 19 and for the cylinder 21.
  • the log delivered from the rewinder 5 (better illustrated in the perspective view in Figure 6 ) is constituted by a central winding core A, made of plastic, cardboard or any other suitable material, removable if necessary, on which there are formed two windings indicated respectively with L A and L B .
  • the two windings L A , L B are constituted by the same length of web material N 1 and N 2 respectively.
  • the winding L A is formed of a certain length of plies V A1 , V A2 joined to one another in the embosser-laminator 17, while the winding L B is formed approximately of the same length of web material N 2 constituted by joining the plies V B1 , V B2 embossed and laminated in the embosser-laminator 17.
  • the reels B A1 , B A2 are formed of plies V A1 , V A2 having at least one characteristic that distinguishes them from the plies V B1 , V B2 forming the reels B B1 and B B2 .

  • the reels B B1 and B B2 are formed, for example, of plies substantially without, or in any case containing minimum quantities of, wet strength resins, for producing toilet paper.
  • the widths of the plies V A1 , V A2 and V B1 , V B2 , and consequently the axial lengths of the windings L A and L B are purely indicative.
  • the axial length of said windings and consequently the width of the plies of which they are formed are chosen as a function of the quantity of rolls to be obtained respectively with the plies V A1 , V A2 and with the plies V B1 , V B2 .
  • the movement of the devices to feed the log to the cutting unit and the movements of the cutting blade or cutting blades are controlled so as to divide the windings L A , L B into the desired number of rolls R A and R B (indicated briefly in Figure 2 ) of two different types and of two different dimensions.
  • the rolls R A have an axial length twice that of the rolls R B .
