With printing paper places and cardboard a high bending strength is erwflnscht t r an appropriate operating attitude and an appropriate printability. The bending strength can be increased for example by a Oberfiachenleimen and also by different Gradientenslrukturen (multiple structures and a Gradientenkalandrieren). A high specific volume is gotten for reaching a constant thickness with a smaller quantity of Pulpe. A task of the Oberfiachenleimens is it to improve the Festigkeitseigenschaflen from paper or cardboard to as for example the interior connection firmness (interlaminate firmness) or the upper flat firmness (burlap or Picking). Chemicals a use with upper flat glues are due to their attractive price water-soluble polymers, which exhibit mainessentially strong one. The raw material fltr strong ones covers plants as for example corn, wheat, barley, potato, Maniok, etc., whose tubers, seed, are etc. Herkunflsquellen to strong ones. Strong one (C6 H10 05) consists geradkettige Amylose and branched Amylopectin of. Other chemicals fllr a use with upper flat glues are for example different cellulose derivatives (CMC) and polyvinyl alcohol (PVA). The bending strength is reduced with the Kalandrieren, if the course is compressed, which fllhrt to a smaller thickness and to a reduced specific volume. The computed bending strength erht ht itself proportionally to the third power of the thickness in accordance with the following formula: h2h31 = 111 2 h1 h32 112 2 65403 stocks i “""”: """" "" ù. “: EO 900 oe9o eDe° -2o whereby S, and $2 the bending strengtheningnesses of the kalandrierten and/or kalandrierten paper represent and h, and h2 the thicknesses of the kalandrierten and/or kalandrierten dad jetty represents and Et and E2 the Elastizitatsmodul of the kalandrierten and/or kalandrierten paper represents. The following general description treats Papierund cardboard types and different Kalandrierund of coating processes RIr a use when its production. Papierund cardboard types it exists a wide range at different sorts by paper and cardboard and this k0nnen on the basis of the basis weight (flat mass) in two categories to be divided: Papers with a single situation and a basis weight of 25-300 g/m " and cardboards, which are manufactured possibly in Mehrlagenteclmik, with a basis weight of 150-600 g/m2. As this admits is, the dividing line varies between paper and cardboard, whereby cardboards with the smallest basis weight are easier than the heaviest papers. F [lr paper for printing on and cardboard are usually used for packing.

Cardboards can for example into the following main categories gladly-ate intended application eingeteik to become. Waving cardboard, which is provided with a liner and a Fluting. Box cardboard for manufacturing Behaltern, boxes. Box cardboards cover for example Flllssigkeitsverpackungskartons (FBB ffi cardboard for folding box, LPB ffi flat steel bar sigkeitsverpackungskarton, WLC - white lined chip board, SBS = solvently bleached sulfites, SUS ffi solvently unbleached sulfites). Graphic cardboards for manufacturing for example maps, files, briefcases, keeping nits, covers etc. Tapetenrohpapier. Kalandrieren Ill IIO D • Q • °5° the Oberflacheneigenschaflen and thickness profiles of different papers and cardboards are treated by a Kalandrieren, in order to erfltllen the requirements of a printing process and a further Behandelns. Painted sorts are vorkalandriert typically before a caper process (coating process) and suspended a Endkalandrieren after the caper process. The Kalander are divided in Maschinenkalander, Weichkalander and Mehrwalzenkalander. A Maschinenkalander has typically 1-2 column and both gap training rollers is hard rollers. A Weichkalander has generally 1-4 column and at least one the Spaltausbildungswalzcn is coated by a soft coating. A Mehrwalzenkalander has generally 5-11 column. The roller building group of a Mehrwalzenkalanders enclosure both erw L, 'rnte rollers and yields coated rollers. Special Kalander cover for example a Nassstapelkalander, a Feuchtegl tttwerk and a Langspaltkalander. The Nassstapeikalander is more or less a Mehrwalzenmaschinenkalander identically, however regarding the Kalandrierprozess completely different. The Nassstapelkalander uses effectively humidity gradients, whereby the course arriving at the Kalander has only a humidity of approximately 1-2%. The Nassstapelkalander is with water cults provided for training a water film on the Balmoberfll/che upstream a gap, whereby the film is pressed on the Bahnobedlache in the gap. Thus the course becomes only at the surface wet (damp), whereby the Oberfll [a che stronger Kalandrieren than the Ubertrocknete inside received. The Nassstapelkalander is used as a Vorkalander filr some cardboard types. The dampness smooth work is a Maschinenkalander, which is in the dry end of a paper-making machine. Langspaltkalander cover a Schuhkalander, a soft belt around a Schuhwalzv have and with that the cleavage typically 50-400 mm beü /gt, and also Riemenkalander. The conventional Riemenkalander consists of a thermal roller of the Weichkalanders, a belt loop and a Gegenwalze inside the belt loop, whereby the latter is either a hard roller or soft whale.

A special Ausfllhrungsbeispiel of the Riemenkalanders is a Metallriemenkalander, whereby the Kalandrierriemen exhibits a metal belt, which establishes around Fflhrungswalzen leaves and together with a Gegenelement, typically a roller, a long gap zone with long ones of even more than 5000 mm. Inside the belt loop the moreover one a press element can be intended, for example a deflection balance roller, use can for establishing one point of gap with higher compression load in the center of the way Qber the long gap zone. Caper techniques types of paper and painting as a procedure ever more popularer, experience the Streichprozusse and the Streichanlage a challenge by increasing requirements, painted there. In the caper procedure and more exactly said in the pigment caper procedure the paper-upperflat with a situation made of caper color (coating color) at a caper head is trained, whereupon running off the water (drain) is expenditure-honoured, which is brought by the caper color composition inside. Training a caper color situation can be divided into the Zufllhren of a caper color to the paper-upperflat, i.e. laying on, and into adjusting the final caper quantity. The most important pigment caper procedure is blade capers so called, with which the caper quantity is stopped by means of a scraper blade so called. The ttblichsten kinds at Klingenstreichk0pfen cover one Klingenstreicheim ichtung, which is provided with an order roller, and a blade coating device, which is provided with a radiation's application. In addition the St calibration process involves the application of a Filmttbertragungsstreicheinrichtung so called, whose application became ever more flblicher in the recent time. Another new technology, which was eingeffihrt ffir high-speed printing paper machines, involves the use of Curtaln coating devices (so-called curtain capers). From the point of view of practice out the most substantial difference between the different caper devices refers to the Auflragprozess and in particular to the penetration arising with it, i.e. to the penetration of a caper color into the paper. During the production of high-quality painted printing papers in the recent time more and more attention not only on a high Qualitat but also on the Produktivitat one put. The Qualitat became in the same way a ever more important aspect with easily painted papers of a kind of mass product. Approximately samtliche coating devices are at the pressure of an increasing Qualitat, Produktivitat and a run speed. - w u ooOO • • oo oo oo: i': ':: 0000 • “0” ““O.00 OOOl =7= in the case of the application of order rollers, which is covered with the Klingenstreicben, laying on is caused by the application of a roller, which turns in a caper pan, in order to take up a caper color to the lower surface of a paper, that by a Gegenwalze bef0rdert. The laid on quantity amount to normally 200-250 g/m2. In the case of the application of order rollers the caper color penetrates effectively into the basis paper. In addition the fibers of the basis paper have sufficiently time to pour before the blade use to swell (), with which the roughness volume of the paper increases. I0 during radiation's application (Strahlauflragen) is supplied the caper color again directly on the Bahnoberflacbe by means of a D e. An advantage approximately/more lber the Auflragwalzenanwendung is the absence of a turning roller and therefore an improved suitability fllr high run speeds. A further advantage is a less kralliger impulse of the Auflragdrucks, which fllhrt to an improved operating attitude. During radiation's application the Balmbefeuchtungsprozess lies between a Auitragwalze and a so-called Short Dwell mechanism. During radiation's application amount to the laid on quantity of typically 130-220 g/m2. With that so-called Short DellAuflragen is supplied the caper color to a Auflragkammer, which is directly behind the scraper blade, whereby a side panel of the chamber is formed by a moving paper web, which is gestutzt by the Gegenwalze. The moving paper web develops eddies in the order chamber, and the caper color has a Fiießgeschwindigkeit on the upperflat of the course, which is equal to the speed of the paper web. With the Short DellAuflragen is moistening the paper geringfllglg, if the Auflragzone is exposed to a low pressure and is short the effective range. Swelling the Papieffasem results partly only stromahwartig the scraper blade, which thaws the upperflat out geglittete by the blade. Thus the caper-smooth, which is erzieibar by a Short DwellStreicheiurichtung, is underlaid for against silver of those, which are obtained by a Auttragwalzenstreicheiurichtung and a Stralflstreicheinrichtung. The caper quantity remaining at the upperflat of the paper is affected by a wide range at variables. If like the roughness, which Porositat and the Wasserabsorption increase, the caper quantity increases such characteristics of the basis paper likewise. In aimlicher way, if the Trockengehalt and the Viskositat of a caper color increase, the caper quantity takes too. On the other hand an increase of the Wasserhaltekapazitat of a caper color reduces the caper quantity. If the tension, which Arbeitswinkei and the Kiingendicke of a scraper blade - v v 0000 • • O • o • o • • °8° increase, the caper quantity is again reduced. Which concerns the other factors, then an increase of the run speed and an increase of the Auttragdrucks ttlhren to an increase of the caper quantity. Supplementary light to that managing described blade coating devices can be ausgefllhrt the caper treatment and surface treatment also by other devices. Below some very ttblich used options are descriptive. The Leimpressenei eit consists itself of two turning rollers. With this alternative on the Oberfl, 'iche a course which can be laid on caper color is laid on on the course in basins l0 existing between the course and the rollers. Additionally to that upper flat glues can the size press fllr pigment capers be also used. The caper quantity amount to unge/thr 1.0-2.0 g/m2/Seite. A problem with the standard size press is the Instabilitat of the Auflragbeckens with high run speed rates. There attempts was undertaken, the problem too by shapes of film size presses eliminates, with which a situation of a caper means or a glue means, which is erwttnscht at the upperflat of a paper web, is laid on first on the surface by Presswalzen, whereby the situations happen from there to the paper in a gap between the rollers. The applied outer ones rising up devices exhibit units similarly as with the Short Dellcoating devices. The advantages obtained by this Gerbt cover a steered laying on even at high run speeds and a M0glichkeit of a Pigmentstreichem (2-6 g/m2/Seite). DurOber outside can be increased the Trockengehalt of the caper color regarding a standard size press. Painting filming realm colors can be ausgefllhrt either in a one-sided or in a bilateral way. The operating attitude of a Filmtlbertragungsstreichprozesses is 9blicherweise relative to that blade capers well. Compared with the Klingemtreichen by a Filmtlbertragungsstreichen is obtained caper situation usually better in relation to the outline conformal and has a gr0Bere Bedeclamg in this sense. It is not possible however, high caper quantities (ttber I0… to reach 12 g/m2) by a FilmBbertragungsstreichen. With the LuttbOrstenstreichen laying a caper color on is implemented either by a Einzeloder Mehrwalzenldingenauflraggerat or by means of a box. The attitude of the caper quantity and the Glattens of the upperflat again by means of a Luflstrahls are ausgefllhrt. The Luflb0rstenstreicben almost exclusively applied with a Kartoastreichen due to excellent covering planned thereby. The disadvantages cover a limited run speed of the procedure and very small Trockengehalte of the caper color. The caper situation, which is trained by a Luftbürste, has a consistent thickness, which is conformal the Obertlachenkonturen of the paper. In accordance with reason, 'ttzliche L0sungen is planned today regarding painting a paper web by Short Dwell.Streicheinrichtungen and Aut rising up rolling coating devices, a plant on the basis of a Strahlau agent and film size presses. A general general-purpose coating device is valid to still arrange it. The blade capers in its different forms at the furthest common Sü'eichverfahren and seems it is also in the future to remain. Since the run speeds increase and expand the ranges t'dr an applied painting, the Auflragwalze will be probably replaced annabemd completely by passwords on the basis of a Strahlauflragens. In addition appearing a new technology is a Curtäin Sü'eichtechnik so called. CurtainStreicheiru'ichtungen kOunen in Langsamzufllhrstreicheinrichtungen and Gleitzufllhrstreicheinrichtungen to be divided. In a Gleitzufllhrvorhengsstreicheinrichtung a caper mass is to it-brought that it flows along a bent level, and a curtain develops, if the caper mass 0ber the edge of the level runs. To SchachtzufUhrauflragbalken a caper mass is pumped by a distribution chamber to a narrow vertical pit, whereby a curtain (from there it Curtain) develops along its lip and runs downward to the course. A caper mass can be laid on in one or in several situations. Compared with that blade capers applies that curtain capers or Curtainstreichen much less Kraft on the course and thus to fewer interruptions, which are caused by a course tearing in the paper web, with which the operating attitude is improved. The curtain capers is not able to be planned a smooth one which equal that is, which is obtained by the blade capers, however is better the coverage obtained thereby than that one, which is obtained by the Klingenstreicben. The fundamental idea was it that cu inStreicheinrichtungen, “finally the Luftb/h'ste replace. The Finnish patent FI 115,732 reveals a procedure and turns out, by which the penetration of an upper flat glue means into a fiber course can be improved by means of a negative pressure device. MOO0 • • • • O - lOEs a task of the available invention is to create a password which is in addition able, the bending strength and the specific volume of flat paper/cardboard regarding such values further to improve, which by standard upper flat glues and enclosing a Kalandrieren is obtained. In order this task to loose, is characterized a procedure of the available invention by the fact that writing in such a manner exhibits a treating of a fiber course with a chemical obtaining a drying shrinking that the chemical essentially completely penetrates through the fiber course thickness, and afterwards the fiber course is brought to the fact that they erwarnten to a treatment zone between two metal-flat with the result progress that the humidity walks within the fiber course to a middle section, l0 whereby the middle section as a result of the increasing humidity swells and to the Obcrflachenabschnitt of a high Troclmungsspannung is exposed, since is prevented that the Obedl shrinks henabschnitt, and if the fiber course from the Bchandlungszone out-does, the evaporated water fast through the upper twisting pores without substantial condensation in the upper flat situations it escapes which to a increased Elastizitatsmodul fltr the upperflat and to a small density fllr the middle section ft on the other hand is simultaneous a device of the available invention thereby marked that the device exhibits a Auttrageinheit, by which a chemical obtaining a drying shrinking on a Faserbehn in such a manner more aufbringber is that the chemical essentially completely penetrates by the fiber course thickness, and the fiber course is adapted to the fact that they erwarmten by a treatment zone between two metal-flat with the result progress that the humidity surprises within the fiber course to a middle section, whereby the middle section swells as a result of the increasing humidity und'der upper flat section of a high drying tension suspended will, there it is prevented that the upper flat section shrinks, whereby, if the fiber course from the treatment zone out-steps, which evaporated water fast by the Obcrflachenporen without substantial condensation in the upper flat situations escapes, which to a increased Elastizitatsmodul the upperflat and at the same time to a small density filr the middle section flat steel bar t. The available invention is below more in detail descriptive with reference to the beigefllgten designs. FIG.

With reference to FIG. I points the example-like device one by vacuum (negative pressure) claimant Obertlachenleimeinheit, as she is descriptive for example in the Finnish patent flat steel bar 115,732, and a Metallriemenkalander 10 up. The Oberflachenleimeinbeit has a first Auflragvorrichtung la for laying a Starkel0sung on on a first course side W1 and a first negative pressure device 3a, whereby the negative pressure, which is present in their, is used, in order to produce and over cause a difference of pressure more elber the thickness of a course W that the Starkel0sung walks and penetrates the inside the course W up to a desired depth. The l0 example-like device has the moreover one a second Auftragvorrichttmg lb, which is so arranged that it is turned to a second course side W2, and a second negative pressure device 3b, which is so arranged is turned dnss her to the first course side wl. This structure makes a bilateral surface treatment fllr the course for W possible, whereby the course W is carried sü'omabwartig the first negative pressure device 3a by means of F01mmgswalzen 8 to the second Aufüagvorrichtung lb. After a surface treatment of the first Balmseite wl it can be advisable that the course W is dried at least up to a certain measure before the upper flat treating of its second side W2. This is represented to dryer, which is named the reference symbol 9 by one kontaktfreian and which is more lnfratrockner for example. In addition FIG shows. 1 Umlankwal n and Fülmmgswalzen, which are shown with the reference symbols 4a and/or 5a and which serve to turn the Lauffichtung back as desired the course W. The Metallriemenkalander 10 has a Kalandrierriemen 12, which is made of metal and which around guidance rollers 13 rotate. The Kalandrierriemen 12 progresses around a roller 15 around, which is arranged by it outside, whereby a Kalandrierzone between the belt 12 and the roller 15 is established. A too kalandrierende Materialbahn W lauR by a Kalandrierzone N, whereby it is exposed to a erwflnschten printing impulse and a desired Warmewirlamg as a function of the time. In FIG. I is represented a dot and dash line 19, in order to replgsentieren a kind at printing effect, which is arranged always then auflrirg if inside the Kalandrierriemens 12 a roller gap 14, that as a press element one functions, whereby the belt against the roller 15 one gedrangt, in order to establish a Spaltzone with higher pressure within the Kalandrierzone. On the other hand a broken line 18 is shown, in order to represent a kind at printing effect, which arises whenever within the Kalandrierzone a working kiss pressure is only produced by means of a tension of the belt 12, if the gap roller 14 from a butt contact with the belt 12 arrives except interference (or if head a gap roller 14 inside the belt 12 is not inserted). oo •: 'i.i. O0 • O00 in accordance with the available invention was discovered that the bending strength and/or the specific volume flat of a paper/a cardboard can be improved, by being caused upper twisting glues with one by negative pressure beU'iebenen order value, which a treatment process follows for preventing or limiting a drying contraction, what to increased drying tensions f t. This Photomen is formed on a Tmcknungssclu'umpfunterstützungseffekt of strong ones, whereby preventing the Tmc ungsschrumpfens after the Hinzufugen of strong ones too erhSh n dry us tensions t blank. As a Metallriemenkalander during a treatment process is used stmmabw industrial union of the Oberflacbenleimens, drying can be brought to a course in a gestatzten condition within a closed gap, which is realised by a metal belt and a roller, with itself, with which a steered development of the drying tensions is made possible. The upperflat of a fiber course between the hot upperflat of a Metallriemenkalanders experience drying and the humidity walk to a middle section, whereby the increased humidity and thus an increase of the specific volume cause a swelling of the middle sections of a fiber course, what the thickness raised. At the same time the upperflat Tmckmmgsspannungen develops, whereby a Elastizitatsmodul of the upper flat sections raised becomes. If the fiber course from the treatment zone out-steps, the condemned water existing in the middle section escapes by flat without condensing (a relaxation just now before of the received Elastizitatsmoduls to cause became), whereby the structure obtained in the Metaliriemenkalander remains essentially unchanged, and the result is an improved bending strength of the fiber course. This schafl large savings regarding the raw materials and improvements regarding the Qualitat. FIG. another possibility for improving a surface treatment shows 2. A Behnndlungslosung 30 of FIG. 2 one causes, by one Filmttbertragungsstreicheim ichtung and a Metallriemenkalander are combined. A Oberfi henbehandlungsmittel, as for example a Oberflachenadhasiv (bonding agent) on strong basis, is distributed at the top side of a Auttragwalze 31 by means of an order device 32. The surface treatment means is supplied by the top side of the Auflragwalze in a Fihnübertragungsspalt to the upperflat of a fiber course W. The film transmission gap is established between the Auflragwalze 31 and a Gegenwalze 34. By the gap the moreover one a Metailriemen 33 extends for causing painting and the Metallriemenkalandriereus of a fiber course in a Einzeispalt. A metal belt gap makes the use of high temperatures possible. If it out-steps from the gap, the fiber course is striking drying due to a contact drying, and in Abhangigkeit of the run speed and the temperatures it is m0glich to obtain sufficiently high Trockengehalte for eliminating the need at separate drying. This hybrid solution creates large savings in the view auflnvestitionen and for Ben'iebskosten possible, and makes at the same time a Zunalune of the bending strength of a fiber course, as drying contractions in the metal belt gap are prevented. The Oberfl used into that managing mentioned passwords henbehandlungsmittel is preferably a CHO polymer. The CHO polymers are polymers, which only carbon (C), hydrogen (H) or oxygen (0) contained. Stromaufwl [rtig the Metalkiemenkalanderns can be laid on on the surface of a paper or a cardboard a CHO polymer or a CI-IO-polymer, which contains a mixture.

The upperflat of the printing paper can be treated by means of custom-made chemicals, so that an improvement of the printingupperflat is obtained, as a very small quantity (less 0.5 g/m2) of a chemical is used. A such chemical is for example a polymer, whose hydrophobische characteristics are strongly on it dependent, like the Polymermolektll on the Oberflacbe sits down, by opening the Polymermolekularmizellen (or Molelmlarcluster) to the Oberflacbe of the Papieffasern the hydrophobischen groups to molecules directly of the Oberflacbe is away addressed. Thus can be used opening of the Molelmlarmizellen, in order to arrange the hydrophobischen effect (or the effect on the resulting Druckqualitat) maximum. Opening the Mizellen to the Oberflacbe of the fibers can be unterstutzt by a warm treatment afterwards to chemical laying on, for example by a treatment in a Langzeitl flundfierriemenzone (some ten Milliselomden or casually). In particular the process with a Metallriemenkalander can become ausgeflllm. The treatment can exhibit different thermal treatments, which are used with the Trodmen, as for example a hot-air bath however sees alternative a Kalandrieren and a warm treatment, which take place at the same time, advantages forwards, since the printing paper must be kalandfiert anyway after the chemical treatment, and therefore the Mizellenbehandiung with the Kalandrieren can is integrated. The chemical can be laid on to blade capers by any so far well-known Auflragverfahren, as for example a FR hfilm0bertragung, or curtain capers. In the case of a multiple curtain cancellation preferably contain the covering realm situation this polymer. Therefore it can be foreseen that the final sequence of the chemical preparation at the paper surface arises, if the structure of the Polymermolekale a desired final result is conditioned by a thermal treatment, which is caused at the upperflat of the paper. This password plans betrachtliche advantages. “o' o oö oö ooooo o œ ù: : .i .i .i. ÷ " ““ö.: - The requirement of a chemical treatment can to be arranged minimum and it be able still important advantages to be obtained, whereby the effect of the chemical is arranged maximum, since the hydrophobische effect of the polymers is verstarkt by the thermal treatment. S - Painting, which form chemical treatment and the Kalandrierprozesse are continued to integrate. Innsbruck, characterized in 29 October 2008 Patentansprflche 1st procedures for the Oberflachenhehandeln by paper/cardboard, by the fact that the procedure in such a manner exhibits a treating of a fiber course with obtaining a chemical a drying shrinking that the chemical penetrates essentially gtlnzlich through the fiber course thickness, and afterwards the fiber course is brought to the fact that it to a treatment zone (N) between two erwarmten Metallflttchen (12, 15) with the result progresses that the humidity walks within the fiber course to a middle section, whereby the middle section swells as a result of the increasing humidity and is suspended the upper flat section of a high drying tension there is prevented that the Obertlachenabschnitt shrinks, and if the fiber course from the treatment zone out-steps, which evaporated water fast by the Obertlachenporen without substantial condensation in the upper flat situations escapes, which fIlhrt at the same time to a increased Elastizitatsmodul fllr the upperflat and to a small density fllr the middle section. 2. Procedure painted requirement 1, by the fact characterized that the procedure the application of an equipped of a Behandlnngseinheit with a metal belt (10), those exhibits the treatment zone between the erwarmten metal-flat (12, 13) realised. 3.
