- DE-A-2455895 relates to a method for producing a multi-layer, absorbent paper wipe, taking on at least one side a relatively inextensible middle layer of tissue paper a continuous pattern of a water-resistant, reinforcing synthetic resin, whereby this pattern covered between 15 and 50% of the entire surface and in certain Spaces on both sides of the middle layer an outer layer of one highly stretchable, creped tissue paper on the outer layers mentioned shaped embossing points is glued.
- DE-B-2149103 relates to a multi-layer composite material for absorbent paper towels, which is characterized in that an inner layer from a creped absorbent cellulose wadding that at least in the material plane is extensible in one direction, sandwiched with at least one outer Position on a creped absorbent that is less extensible in one direction Cell wadding is connected, the or each outer layer being connected to the middle one Position protruding, spaced embossments and on at least some of these embossments with the inner layer by adhesive is connected in such a way that there are unbound between the connection points Zones. From Figure 1 and there in particular the reference numerals 7 to 10 respectively 17 to 20 shows that the layer adhesion is given by two gluing units is. It is not possible with this that the central position is designed to be freely movable. A similar situation can be found in US-A-37 38 905.
- DE-A-4414238 relates to a household or hygiene paper consisting of at least one, preferably two to four layers of tissue paper, the paper with an embossing, in particular for layer attachment, which is characterized by is that the household or hygiene paper after its embossing and if necessary, arrest of layers is recalendered. Except for this special post-calendering this document sets the subject of the present invention as claimed, not close, but especially not the unstamped freely movable Central location.
- GB-A-2255745 is a paper product consisting of at least two layers known, in which the layers are at least partially embossed and knurled are connected, dyes arranged in the manner between the layers are that a color is visible at points where the first layer with the second layer comes into contact.

- the middle layer is also fed in at the embossing station an embossing roller is assigned to a counter roller.
- a disadvantage of most of the aforementioned tissue products that have a continuous Having embossing on all layers is that the embossing knobs on the tissue product can be felt on the other side, which is not considered advantageous by the end user becomes. Furthermore, such pimples are considered by the end user as little viewed softly.
- the multilayer, web-shaped tissue product specified in such a way that at least one of the External layers, in the case of a roll product usually the external layer, the observer facing outer layer, applied to at least part of its surface Has (layer) embossing that is independent of the layer liability generation is.
- each of the two outer layers has at least two superimposed embossings e.g. micro and macro embossing, possibly motif embossing, to create certain functional properties such as softness and volume (bulk) in combination with one that consumers find interesting optical appearance.
- embossings e.g. micro and macro embossing, possibly motif embossing, to create certain functional properties such as softness and volume (bulk) in combination with one that consumers find interesting optical appearance.
- the multilayer, web-shaped tissue product connects the layers, for example by mechanical action, optionally also by gluing generated layer adhesion, on a part of the total surface of the tissue product is limited and thus creates sufficiently large zones in which one Mobility of the individual layers relative to one another with appropriate stress is possible and this gives the impression of increased softness (subjective impression of softness, especially increased softness of crumple) with a sufficient for use Has bond strength.
- the distribution of areas with layer adhesion can zone-shaped, for example stripe-shaped, narrow, as with conventional knurling inside the "tissue surface" of the tissue product of the tissue product section parallel run to the edge, with one or more such knurled zones being common.
- the strip-shaped area which has a layer adhesion, can according to another preferred embodiment of the present invention also an enlarged Have width, such as with a knurled width with a strip width from 5 to 40 mm per strip or together 10 to 80 mm. Two such Stripes are then parallel to the cut edge of the multi-layer, web-shaped tissue product in direct connection to the cutting edge and range accordingly Width from the cut edge to the inside of the surface of the tissue product.
- web-shaped tissue product becomes the knurling pattern of knurling, in particular the wide knurling, the embossing pattern of the layer embossing.
- This Compensation of the layer embossing pattern and connection embossing pattern can lead to identity and register accuracy are driven, which leads to an optically complete disappearance the connection embossing leads in the pattern of the layer embossing.
- a further adjustment is already sufficient, in which the zone of arrest compared to the layer embossing it is no longer noticeable and none of them Bead negatively influencing optics and haptics by the connection embossing occurs.

- the zones with layer adhesion are relatively small, i.e. punctual (spot embossing, if necessary with structural laminating) before, these zones with layer adhesion evenly distributed over the entire area of the tissue product are that in the resulting gaps the mobility of the previously shaped Outer layers relative to the unembossed middle layer (s) are preserved and these zones without layer adhesion similar to an air cushion to that described Improve softness and improve the impression of volume.
- the multilayer, web-shaped tissue product post-smoothed or calibrated.
- smoothing i.e. under constant pressure or by calibration, i.e. through a constant roughness with the help of a smoothing tool, the roughness peaks of the previous ones Embossing (s) eliminated, whereby the surface softness (surface softness) in addition to the improvement in softness according to the invention (body softness) is increased.
- the thickness of the tissue product is primarily determined by calibration equalized, which contributes to an improvement in the winding structure. With the thickness improvement goes hand in hand with an improvement in softness that however, in many cases falls short of the improvement in softness due to smoothing.
- the embossing of at least one of the outer layers in such a way that this is achieved by at least an embossing station takes place in which an embossing gap is formed in that a masculine nub-bearing roller with a steel surface of a counter roller with a rubber surface, a plastic surface, a paper surface or is assigned to a steel surface.

- CTMP chemi-thermo-mechanical pulp
- HTCTMP high temperature chemi-thermo-mechanical pulp
- the multi-layer, web-shaped tissue products also count all those whose outer and / or inner layer (s) are made of tissue qualities were selected, the one or more of the aforementioned features in any Combination included, with certain properties of those used Tissue qualities during the manufacturing process of preliminary or finished products can be influenced in a targeted manner by adding chemical auxiliaries.
- the strength of the tissue quality used can be added of dry and / or wet strength agents or the softness by using suitable Plasticizers (softeners), optionally in combination with creping aids and the use of softness-enhancing crepe technology or the absorbency for liquids by adding absorption aids to a desired level can be set.
- tissue papers in which the outer and / or inner layer (s) can be selected from different basis weights in the range from 12 to 40 g / m 2 , preferably 14 to 23 g / m 2 , but especially from the range of 15 to 21 g / m 2 per individual layer.
- At least one of the layers, preferably one of the inner layer, in the multilayer, web-shaped tissue product should contain at least 50% by weight, preferably at least 80% by weight, in particular up to 100% by weight, of recycled paper or Waste paper included.
- Typical basis weight ranges of these paper qualities both for the inner and for the outer layers are basis weights of 12 to 40 g / m 2 , preferably 14 to 23 g / m 2 , in particular 15 to 21 g / m 2 per individual layer.

- connection with the multi-layer web-shaped tissue product provides additional cohesion via a connection embossing by at least one on the surfaces, in particular of the end face (s) of the knurled wheel knobs present, which preferably is round or angular.
- a connection embossing by at least one on the surfaces in particular of the end face (s) of the knurled wheel knobs present, which preferably is round or angular.
- the object of the present invention is a method for producing a multilayer, web-shaped tissue product, which is characterized in that that between two outer layers, one of which on at least one of the outer layers (Layer) embossing at least over part of its surface in one of the layer adhesion generation upstream, independent process step applied is arranged, at least one unembossed middle layer, which is essentially free is mobile.
- a method for producing the multi-layer, web-shaped tissue product provides that both outer sides at least one over have (layer) embossing covering part of the surface of the respective outer layer, which is applied independently, before the layer adhesion generation, where the outer layers have the same or different pattern (embossing pattern) Receive embossing, using a similar embossing pattern especially for the (layer) embossing of the outer layers over their entire surface is preferred.
- the embossing pattern of the superimposed layer embossing procedural are essentially predeterminable, with the successive method steps the embossing an outer layer first a micro-embossing and then receive a macro embossing, the macro embossing if appropriate is an embossed motif.
- Overlying layer embossments of the outer layers are functional product properties, such as firmness, softness, volume with one for the consumer interesting optical appearance of the tissue product can be influenced, whereby the procedural trick to leave the middle layer (s) unembossed in interaction with only a portion of the total area of the tissue product (Section) limited connection of the layers to each other (Layer adhesion area (e)), the essentially free mobility of the unembossed Inner layer relative to the previously embossed outer layers guarantees what the desired consumer-significant improvement in softness (softness of crumpling) leads, as a subsequent consumer test shows.
- the arrangement takes place in such a way that the outer sides of the embossed outer layers soft and the inside of the embossed outer layers are rough. This means that the outer layers merge when embossed to the finished product so that the layers are embossed in the tissue paper of the outer layers produced embossed nubs from the outside of the later Tissue product after the unembossed middle layer (s) to be aligned.
- the as rough Perceived embossed nubs are supported on the unembossed middle layer, see above that the opposing embossed knobs or approximately opposite one another Do not hook the embossed knobs together, but instead when subjected to stress Shear or bending forces acting on the outer layers are relative despite being embossed can move to each other by embossing the outer layers on the unembossed Can slide along the middle layer.
- This method according to the invention leaves a desired distribution of the areas with mechanical action to generate layer attachment, in which the Areas with mechanical action according to a given pattern, based on the surface of the tissue product (sections), taking into account aspects how durability of the ply connection during manufacture and during later use, simplicity of manufacture, good visual appearance, etc. are arranged.
- the areas for the generation of layer arrest are being processed by means of mechanical action, optionally with additional gluing, zoned, For example, narrowly arranged in strips so that these zones inside the later surface of the tissue (tissue product / section) runs parallel to the edge, the method providing for the creation of one or more such zones.
- Each of the two strip-shaped Areas with layer adhesion have a when using this wide knurling Width of 5 to 40 mm according to the invention, taken together 10 to 80 mm, wherein the method according to the invention has an essentially matching width of both Has marginal zones (with layer adhesion).
- Layer adhesion through mechanical action in the manner explained above is, for example produced by a method with the help of a connection stamping station at through the tissue web according to the invention, consisting of several tissue layers a further embossing gap is made, which is formed from two rotating steel rollers, of which a harder steel roller carries masculine embossed nubs, while the other, softer steel roller has a smooth surface and in which the masculine Nub-bearing roller in this way against the smooth surface of the counter-roller is pressed that the tissue layers located between the rollers of the tissue web in the press nip at the points where embossed knobs of the knobs bear Steel roller is deformed, with its knobs in all tissue layers map so that the tissue layers leaving the press nip now themselves Wear pimples.
- the intensity of the deformation in the tissue (formed pimple) as well as its plastic and elastic content depend on moisture, composition, structure and physical properties of the tissue on the one hand and the specific surface pressure on the other hand, in the area of the knobs by pressing against each other the rolls is produced.
- the surface pressure that can be generated is in turn one Function of the number of knobs per unit area, the distribution pattern of the knobs, the Stud geometry, in particular the size and shape of the end face of the studs as well the formation of the nub flanks and the effective contact pressure.
- the pimpled steel roller of the connection embossing station becomes narrow sections divided, one speaks from a certain ratio of coat length Roll diameter of wheels. These narrow roller sections serve exclusively the layer arrest of the individual tissue layers of a multi-layer tissue and these pimple-bearing "wheels" do not cover the entire width of the tissue web but are zoned as separate individual wheels to certain points of the Tissue web limited, so we usually speak of so-called knurled wheels.
- the embossing is carried out in such a way that through the process of embossing the connection Knobs appear in the tissue, which are in an approximately rectangular or parallelogram-shaped, arranged in particular square or rhombic grid are, whose rows and columns are approximately the same oblique to the edges of the web (Cut edge of the tissue product) are arranged.
- the front and foot surfaces of the knobs produced (shown) in the tissue can show regular shape, for example n-angular, diamond-shaped, rhombus-shaped, square, square, round or oval etc.
- these can be frontal and Buttocks of the nubs also irregularly in the form of any pattern be designed.
- the mechanical influence is possibly connected with the layer adhesion is produced with gluing, on small areas, measured on the total area of a portion of the tissue product rather limited punctiform areas that be evenly distributed over the entire area of the tissue product so that in the resulting gaps the mobility of the previously shaped outer layers relative to the unembossed middle layer (s) is preserved and these zones without layer adhesion similar to an air cushion to the described softness improvement and lead to an improvement in the impression of volume.
- the finished product is created by a time sequence to be determined several process steps through the mechanical setup of the processing line (Processing machine or system) can be realized.
- the raw tissue webs provided as outer layers point an embossing made in an upstream process step, and these become then together with the unstamped inner layer (s) Process subjected to, where appropriate, supported by mechanical action by gluing, a layer adhesion between the layers is generated, so that, for example, by means of embossing or non-embossing Differences in length (elongation) of the individual layers in the composite are no longer compensated can be. Without such an individual regulation of speed and Pull each single web (tissue layer) in connection with appropriate spreading every web, starting from the unwinding through each individual process step representative station up to the winding, it turns out a production of end products with an unembossed middle layer as less desirable.
- the control strategy for a preferred embodiment of the production method of a multilayer, web-shaped tissue product according to the invention with an unembossed Middle position, which is essentially free to move, has to meet the requirement that the speed of each individual layer of the multi-layer tissue product to be produced at the inlet of the connection embossing station (knurling or wide knurling if necessary) is the same and this to the transport speed of the connection embossing station (Peripheral speed of the driven embossing roller) in such a ratio stands that the tensile stress in each of the supplied tissue webs (Single layers) almost takes the value zero, so that different length changes individual layers as a result of different force / elongation behavior, for example the embossed outer layers compared to the unembossed middle layer (s), be avoided before entering the connection embossing station.
- the speed of the master drive of this first layer embossing station continues the subsequent connection embossing station (knurling if necessary wide knurling station) with a small positive difference regulated in a feedforward control that the tension occurring in this tissue web (layer) between the first layer embossing unit and the following stamping station almost takes the value zero.
- Positive difference means one compared to that of the leading embossing station only slightly higher speed of the connection stamping station, which is sufficient the tissue web without significant stretching and without wrinkling or undesirable To keep sagging taut and to transport.
- the control strategy of a method for producing a tissue product according to the invention further provides that the web tension of each further tissue web, the forms a layer of the tissue product (via the one already described Outside location), over the speed of the upstream station is regulated, guided by the speed of the connection (knurling, if necessary Breiträndel) station.
- the layer embossing station of the second embossed outer layer (s) then takes the lead the upstream associated unwinding in such a way that on the drive the unwinding, the peripheral speed depending on that of the layer embossing station is adjusted so that a desired for the tissue web (s) can be specified Tension can be kept constant.
- the transport (peripheral) speed of all on the connection embossing station The following stations are conventionally based on the state of the art regulated.
- a facility for Manufacture of tissue products of the aforementioned type contains Means for unwinding mother rolls 21, 22, 23 and means for determining and regulating the web tension 44, 45, 46 and transport speed (Peripheral speed of driven rolls / parent rolls) for each, if necessary Tissue web individually, if necessary from station to station between unrolling, first Layer embossing, subsequent connection embossing and, if necessary, further subsequent ones Stations, possibly via controllable individual drives and means for and Guiding the tissue webs 18, 19, 20, consisting of a first (layer) embossing station 24 from at least two separate embossing mills, for the tissue webs 18, 20, one further (connection) embossing station 25, which forms an embossing gap in which several narrow embossing rollers 26, optionally knurled wheels or preferably wide knurled wheels, a counter roller 27 are assigned
- Such a device preferably contains at least one first layer embossing station 24 a pair of rollers, in which a roller with a steel surface, the masculine Noppen carries, a roller with a rubber surface, a plastic surface, a paper surface or is assigned to a steel surface.
- the smoothing unit itself may be designed so that the tissue web once through the gap (or several columns in a row) of a pair of rollers, if necessary several pairs of rollers is performed, in which first a smooth roller with a Steel surface of a smooth counter roll with a plastic surface and then mirror image of a smooth roller with a plastic surface of a smooth counter roller with a steel surface (soft smoothing).
- the smoothing can also be done so that a smooth roller with a Steel surface is assigned to a smooth counter roll with a steel surface.
- the printing unit is used, for example, to apply a pattern, a lettering, Logos etc.
- Embossing station 24 Feeding the tissue webs from the unwinds to the embossing stations (Embossing station 24) in the case of the outer layers as well as all other tracks including the non-embossed middle (inner) layer (s) to the connecting embossing station 25 and the guidance of the tissue product web takes place through further subsequent stations in a preferred embodiment of a device for producing an inventive Tissue product preferably via means that speed and the stretching behavior of the embossed tissue webs compared to the unembossed ones Path (s) as a function of the speed of a first layer embossing station and that of the connection embossing (knurling, possibly wide knurling) station regulate, for example through individual unrolling with appropriate train regulations, Web guides including spreader devices.
- the layer embossing patterns are largely identical to the embossing pattern of the connection embossing, which in addition to the technical advantage that the multi-layer tissue narrow web everywhere has approximately the same properties, also has the advantage that the embossing strips 4, 5 visually hardly differ from the embossing pattern between these embossing strips Lift off the lying zone without layer attachment 14.
- the trunk 15 is then cut by which are guided with saws and knives approximately in the middle of the embossing strips 16, as indicated by dash-dotted lines 17, into a number of rolls with fewer axial length divided.
- These have those for the use of the tissue product intended width and contain a wound tissue narrow web length, which results from the section (sheet) length determined by the perforation cut and the given number of sheets.
- the reference number 51 represents the grid spacing of the next adjacent embossing knobs, which are on parallel circumferential lines A-A is a reference line along which a section is perpendicular is led to the flat development of the roller surface, in which 3 on the oblique reference line successive embossed knobs are cut so that the contour of the knobs is visible in a side view.
- Figure 9B shows the flat development of a surface section with knurled (wheel) knobs in high magnification, which is analogous to the layer embossing Process by creating one through all tissue layers of the tissue product deformation of the tissue web that becomes effective, embossing knobs in the tissue trains that mechanically connect the individual layers.
- the distance 70 that is between parallel reference lines of the same edges of the End faces of successive knurled knobs to those of neighboring knurled knobs is particularly preferred embodiment shown equal.
- the distance 69 A parallel edges of the diamond-shaped end faces of each one Knurled knob 69 is the same and has in a particularly preferred embodiment a value less than 2 mm.

Description
- Eine verbrauchersignifikante Verbesserung der Weichheit (hand feel), insbesondere der Knüllweichheit, durch eine leichte Beweglichkeit der Einzellagen relativ gegenüber den durch Lagenhaftung miteinander verbundenen Bereichen.
- Die Beweglichkeit der Einzellagen relativ zueinander wird im erfindungsgemäßen Fall gewährleistet durch eine Verringerung der mechanischen Reibung, die bei Relativbewegungen zwischen geprägten Lagen auftritt, indem die Prägenoppen der zuvor geprägten Außenlage des Tissueprodukts auf der im Vergleich zu einer Prägung glatten Oberfläche der ungeprägten Mittellage entlang gleiten können, ohne miteinander zu verhaken. Den extremen Gegensatz hierzu würden Lagen darstellen, die gemeinsam geprägt werden, wobei durch den Prägevorgang selbst die Prägenoppen der einzelnen Lagen sich bereits im Eingriff miteinander befinden. In einem solchen Falle wirken Relativbewegungen höhere Reibkräfte entgegen, als beim Gleiten der Prägenoppen auf der relativ glatten Oberfläche einer ungeprägten Mittellage. Höherer Reibwiderstand der Lagen gegeneinander wird haptisch als Verringerung der Weichheit, insbesondere der Knüllweichheit, erlebt.
- Vermeidung eines beim Gebrauch unangenehmen Durchfühlens (Hindurchfühlens) gegeneinander gerichteter Prägenoppen, indem diese sich auf der/den ungeprägten Mittellage(n) abstützen.
- Erhöhung der Tuchdicke des Tissueprodukts durch das Abstützen der Prägenoppen auf der ungeprägten Mittellage.
- Verbesserung der Gleichförmigkeit des Wicklungsaufbaus durch Vergleichmäßigung der Dicke trotz produktüblicher Toleranzen der Prägung infolge des Abstützens der Prägenoppen auf der ungeprägten Mittellage bei nicht registerhaltiger Prägung mit der Folge eines verbesserten optischen Erscheinungsbildes, wenn das Tissueprodukt als Rollenprodukt vorliegt.
- Festigkeitssteigerung durch Nichtprägen der Mittellage(n) (Vermeidung Festigkeitsverlust durch Prägen).
- Der Sandwichaufbau des Tissueprodukts ermöglicht die Realisierung von Funktionalkonzepten, etwa die Zusammenführung verschiedener Tissuequalitäten, d.h. beispielsweise weiche Außenlagen und eine oder mehrere feste, ungeprägte Mittellage(n).
- Weiterhin sind verschiedene Prägedesigns auf beiden Außenseiten des Tissueprodukts in Kombination mit einer/mehreren ungeprägten Mittellagen möglich.
- Eine Vielzahl verschiedener Lagenverhaftungsmethoden, wie konventioneller Rändelung (edge-embossing), Breiträndelung (wide track edge-embossing), zonenweise Lagenverleimung (structural laminating), deren Kombination sowie eine Motivprägung zur Lagenverhaftungserzeugung (spot-embossing), gegebenenfalls in Kombination mit Verleimung, gegebenenfalls aus dekorativen Gründen mit farbigem Leim, sind anwendbar. Dies allerdings nur solange wie die Lagenverhaftungserzeugung auf vorgegebene Bereiche oder Zonen des Tissueprodukts begrenzt bleibt und dadurch auf flächig möglichst großen Nachbarbereichen die Beweglichkeit der verschiedenen Einzellagen relativ zueinander beim Knüllen des Tissueprodukts oder einer sonstigen Scherbeanspruchung erhalten bleibt. Dieser Bereich der im wesentlichen freien Beweglichkeit der Lagen ist bevorzugt der flächige Innenbereich des mehrlagigen bahnförmigen Tissueprodukts oder eines Abschnitts hiervon, und das Produkt ist unabhängig von der Art der Lagenverhaftungserzeugung einer zuvor angebrachten Prägung der Außenlagen und besitzt eine oder mehrere nicht geprägte Innenlagen.
- Bereitstellen geeigneter Rohtissuequalitäten, einlagig oder mehrlagig doubliert;
- separates Abrollen von Mutterrollen aus einlagigem oder mehrlagig doubliertem Rohtissue;
- getrenntes Führen der Tissuerollen für Außen- und Innenlage(n);
- getrenntes Regeln von Geschwindigkeit und Bahnspannung, getrennt für Außen-und Innenlage(n) und für jeden Verfahrensschritt, geführt von einem ersten Lagenprägewerk und davon abhängig von der Verbindungsprägestation, gegebenenfalls Verleimung;
- Breitstrecken einzelner Bahnen, gegebenenfalls des Verbundes, zur Vermeidung von Faltenbildung durch Querkontraktion;
- separates, gegebenenfalls gemeinsames Prägen der Außenlagen zur Erzeugung einer Lagenprägung;
- Zuführen der ungeprägten Mittellage(n);
- Vereinigen der Lagen und Verbinden der gegebenenfalls vollflächig oder über einen Teil ihrer Oberfläche geprägten Außenlagen mit der/den ungeprägten Mittellage(n) durch mechanische Einwirkung (Verbindungsprägung), gegebenenfalls in Verbindung mit zusätzlicher Verleimung, wobei die mechanische Einwirkung durch konventionelles Rändeln oder bevorzugt durch Breiträndeln, erfolgt;
- gegebenenfalls Bedruckung;
- gegebenenfalls Einführen von Wickelkernen (Hülsen);
- gegebenenfalls Befestigung des ersten Abschnittes am Wickelkern durch Erstblatt-Beleimung;
- Unterteilen der Tissueverbundbahn in Abschnitte (Einzelblätter) des Tissue-Rollenproduktes durch Perforier-Querschneiden;
- Wickeln der Tissue-Verbundbahn zu Stämmen mit der im Endprodukt gewünschten Anzahl von Abschnitten auf einem vorgegebenen Durchmesser;
- Abschlagen des Stammes bei erreichter Abschnittzahl;
- Verleimung des Endblattes.
- Ausstoßen und Transportieren der Stämme;
- Speichern von Stämmen in einem Stämmespeicher;
- Teilen der Stämme gemäß der von der Stammlänge (Rohtissuebahnbreite auf der Mutterrolle) und der Röllchenbreite (Fertigprodukt) möglichen Nutzenzahl durch Abtrennen mittels Messer- oder Sägeschnitt, wobei der Trennschnitt erfindungsgemäß mittig, jeweils in einer in Papierlaufrichtung ausgerichteten Zone mit Lagenverhaftung, bevorzugt mit einer Verbindungsprägung, insbesondere bevorzugt mittig in einer Breiträndelzone, erfolgt;
- Sammeln, Transportieren, Stapeln, Verpacken der Röllchen, Zusammenführen zu Großgebinden, gegebenenfalls Stapeln auf Transportpaletten entsprechend der Bedürfnisse des Marktes.
