Definitions

  • the invention relates to a method for treating a Web of paper or cardboard, in which one has Apply the coating on the web and then satinize the web. Furthermore, the invention relates to a device for treating a web of paper or cardboard with a Coater and a calender.
  • Paper and board webs are often painted, So provided with a coating.
  • the stroke that also called “coating color” is used to the web an improved surface property To provide.
  • the invention is based on the object, a painted Satin the web at a high degree of smoothness and volume-saving to be able to.
  • This object is achieved in a method of the aforementioned Art solved by placing the web in front of the Satinieren steamed and satined in a wide nip.
  • the Smoothing the Breitnips is characterized in considerable Measurements improved.
  • a Breitnip with a Length in the range of 30 to 400 mm, especially in the range from 40 to 100 mm for coated graphic paper grades and 100 to 200 mm for coated board grades.
  • a nip length can be with Great reliability make sure the dash do not get caught on a roller.
  • the web is calendered in a shoe calender, the one having a circumferential coat Shoe roll and a counter roll, wherein the Counter roll with a surface temperature in the range from 130 to 300 ° C, especially in the range of 170 to 250 ° C operates.
  • the counter roll has thus at least in Inlet and outlet area a temperature above the Steam temperature of water. This ensures that the moisture contained in the dash, or the Moisture, which is additionally applied by the steam has been able to evaporate in the nip.
  • the compressive stresses in the nip are on the one hand so big that the vapor is the surface of the applied stroke can not rip, but on the other hand still one Protective layer may arise, which is an adhesion of the Strokes prevented at the counter roll.
  • you can also reach this relatively low compressive stress sufficient gloss and smoothness values. on the other hand prevents this low compressive stress that the Stick to the counter roll adheres.
  • a residence time of the web in the nip in the range of 0.8 to 50 ms. This residence time is enough to the painted surface of the web sufficiently smooth. In cardboard, the Dwell time tends to be greater, with graphic papers rather less.
  • the web is 10 to 100 ms steamed before entering the nip.
  • the steam then has enough time to work with the applied Stroke to react, so prepare him so far, that the desired smoothness are generated in the nip can.
  • one generates in the inlet and outlet areas of the broad nip a pressure gradient of maximum 2 MPa / mm.
  • the length of the inlet and outlet areas is usually of the order of about each 10 mm.
  • the compressive stress increases in the No more than 2 MPa per mm wide nip. This has to Consequence that the steam adhering to the web or there already condensed, with penetrate into the broad nip can.
  • the wide nip does not form a vapor barrier, like this due to a relatively large pressure gradient for two opposite rolls of the case is.
  • the object is in a device of the aforementioned Art solved by the fact that between the coating device and the calender a Dampf Dahls gear is arranged and the calender as a wide-nip calender is trained.
  • the interaction of the steam application device with the Breitnip calender causes on the one hand that the painted Surface of the track has sufficient smoothness and optionally also obtains a sufficient gloss. On the other hand, but it ensures that the stroke do not get caught on a roller of the calender. you So must not fear that the line of the Detach the web and soil the calender. With the Wide nip can thus be a sufficient quality increase effect the painted surface of the web, without significant volume losses of the web must accept.
  • the length of the wide nip is in the range from 30 to 400 mm, especially in the range of 40 up to 100 mm for coated graphic paper types and 100 to 200 mm for coated board grades.
  • Such Length is sufficient to sufficiently satin the web even if only relatively small Compressive stresses used.
  • the wide-nip calender has a Shoe roll with a circumferential coat and one with it interacting counter roll on.
  • the coat of the shoe roll is supported by a pressure shoe.
  • the coat runs in the manner of a roller and is doing in the field the counter roll and the pressure shoe from his im remaining convex shape concave deformed. This is a relatively simple design to a wide-nip calender to realize. With the surrounding coat can be sufficiently long Breitnips realize.
  • the counter-roller has a temperature in Range of 130 to 300 ° C, in particular in the range of 170 to 250 ° C on.
  • the surface temperature is the counter roll so relatively high. Moisture, which is included in the coating order becomes so it heats up accordingly, so they may can form a protective film that sticks prevents the stroke of the counter roll. possibly the sticking of the stick to the counter roll also becomes prevents the stroke due to the prevailing can dry out at relatively high temperatures and no longer tends to stick.
  • the maximum compressive stress in Wide nip 20 MPa. This is a relatively small one Compressive stress. But it is sufficient to the deleted Smooth side of the web. Maybe she will allow also, that steam, which after applying is not yet is completely condensed on the web, with in the Wide nip can occur, there not further condensed and forms a blocking layer against sticking.
  • the compressive stress increases in the input and Outlet areas of the wide nip with a gradient of a maximum of 2 MPa / mm.
  • the limitation of the increase the compressive stress is for the entry of the vapor advantageous in the wide nip.
  • the steam application device is arranged in the range of 0.3 to 1.5 m before entering the broad nip.
  • the speed of the web which can range from about 250 m / min (400 g / m 2 carton) to about 2,500 m / min (graphic papers, eg LWC 50 g / m 2 )
  • the steam will have until then Although a certain moistening of the coated surface of the web causes.
  • a device 1 shown in the figure serves for Treat a web 2 of paper or cardboard.
  • the train 2 comes from a paper or board machine 3, the is shown only schematically. It is also possible, the web 2 from a supply roll, for example one Jumbo roll to complete.
  • the web 2 first passes through a coating device 4, in which a line 5 on a surface of the web. 2 is applied. In the illustrated embodiment this is the top.
  • the dash 5 is exaggerated here shown thick.
  • the coating device 4 is designed as a "curtain coater", i.e. it has a bar dispenser 6, which is a coating medium, so a coating color or line pigments, in the form of a curtain 7 on the Surface of the web 2 applies.
  • a bar dispenser 6 which is a coating medium, so a coating color or line pigments, in the form of a curtain 7 on the Surface of the web 2 applies.
  • the thickness of the Stroke 5 set relatively accurately. In the figure is the thickness of the stroke 5 exaggerated for clarity shown big. Coating color not from the web 2 is recorded, for example, because of Curtain 7 is too wide, is in a drip tray. 8 collected and the bar dispenser 6 again recycled.
  • the bar delivery device 6 still drying devices arranged the the applied stroke dry. These can be equipped with infrared, hot air, drying cylinders or other means work.
  • a steam applicator 10 is arranged, the steam 11 on the provided with the stroke 5 side of the web. 2 applying.
  • a wide-nip calender 12 In the web running direction 9 behind the steam application device 10 is arranged a wide-nip calender 12, the Also referred to as "shoe calender".
  • the wide-nip calender 12 has a shoe roll 13 with a circumferential jacket 14.
  • the jacket 14 acts with a counter-roller 15 together and forms a Wide nip 16, in which the web 2 is calendered, so with a certain pressure and with an elevated temperature is charged.
  • the counter roll 15 has a plurality of peripheral Holes 17, through which a heat transfer medium, for example Oil or steam, can be passed to the Surface of the counter roll 15 with a surface temperature in the range of 130 to 300 ° C, preferably in Range from 170 to 250 ° C, to provide.
  • a heat transfer medium for example Oil or steam
  • other peripheral bores 17 can also be used Possibilities used to surface the To heat counter roll 15, for example, an induction heater or an infrared heater.
  • the shoe roll 13 has a pressure shoe 18, the is arranged stationary. To close the wide nip 16, the counter roll 15 is in the direction of a double arrow 19 lowered, the jacket 14 of a Pressure surface 20 of the pressure shoe 18 is supported.
  • the pressure surface 20 has in the present embodiment a shape that takes into account the thickness of the jacket 14 to the curvature of the counter roll 15th is adapted. But this is not absolutely necessary.
  • the broad nip 16 has a length in the web running direction 9 in Range of 30 to 400 mm, especially in the range of 40 to 100 mm for coated graphic paper grades and 100 to 200 mm for coated board grades. at a speed of the web 2 in the range of 400 to 2.500 m / min, the web thus takes about 0.8 to 50 ms, to go through the wide nip 16.
