Definitions

  • the invention relates to a method for treating a Paper or cardboard web where the web dries, puts a line on the web and the Before applying the line in a wide nip satin.
  • the invention further relates to a device for treating a paper or cardboard web with an application device for applying a line, in front of which a wide nip calender is arranged.
  • a smoothing cylinder also known as a Yankee cylinder used to the surface properties of the cardboard defined.
  • the smoothing cylinder is the at a certain point Drying section of a paper or board machine installed, where the web has already been dried a bit is. Because the web moisture at the point of the smoothing cylinder can only be changed within narrow limits, this limits the flexibility in producing different ones Varieties or basis weights on the machine and prevents, among other things, that the production speed can be increased.
  • the smoothing cylinder therefore has a wide nip calender replaced, i.e. through a calender, the one Has pressure treatment zone in the web running direction seen longer than a pressure treatment zone that formed between two rollers pressed against each other is.
  • the object of the invention is printability to improve.
  • This task is carried out in a method of the type mentioned at the beginning Art solved by using the stroke as a stroke applying.
  • contour stroke With a contour stroke the surface of the web not leveled, but it becomes a relatively uniform thick layer applied to the surface of the web.
  • This layer follows the contour of the web, i.e. a surface structure that can be found, for example, in of roughness remains largely intact. It is believed that the penetration of brush and / or Ink is evened out in the surface area, so that the ink streaking in the print quality influencing magnitude of the surface structure becomes more uniform and so the print quality improved. It is of course possible after the stroke apply more coatings to the web.
  • the contour line should at least largely be dried before another order is placed. Another treatment of the stroke is of course possible. However, one should avoid that the contour line is leveled, for example by a squeegee or a scraper.
  • the web is preferably dried before satinizing in the wide nip.
  • the train then has a slightly lower one Moisture when it runs into the wide nip. she is generally under the influence of Heat dried further. This way good conditions for applying a stroke create.
  • a treatment length is preferably used in the Wide nip of at least 40 mm. With such a treatment length are also available at higher web speeds sufficient time is available in which the web is subjected to heat and increased pressure can be.
  • Preferably used to limit the wide nip at least one circulating belt.
  • wide snips For the training of There are various options for wide snips.
  • a spray, free jet or roller application Preferably used to apply the stroke a spray, free jet or roller application. All these Procedures are well suited to a stroke to create.
  • Glue, starch is preferably used as the line and / or pigment. These fabrics work well for you Contour line.
  • the line is preferably designed as a primer. Then another stroke on the primer applied. If the primer is designed as a stroke less problems arise later the printability, regardless of what else applied to further coatings on the web becomes.
  • the object is achieved in a device of the type mentioned Art solved in that the application facility is designed as a stroke application device.
  • the application device is preferably a spray, Free jet or roller application device designed. All of these order facilities are well suited to one Apply a contour line to the surface of the web.
  • the wide nip calender preferably has a treatment length of at least 40 mm. With this Sufficient treatment time is guaranteed, so that the web is pre-smoothed to a sufficient extent can be.
  • the wide nip calender preferably has at least a circulating belt. It can be relative Realize large treatment lengths relatively easily, i.e. you can get longer treatment lengths with little effort than when training a nips through two rollers pressed against each other have been realized is.
  • a device 1 for treating a paper or Cardboard web 2 (hereinafter referred to as "web") a wide nip calender 3.
  • the wide nip calender 3 has a roller 4, which with a circulating band 5 interacts to form a wide nip 6 to form.
  • the band 5 is with the help of a pressure shoe 7, which has a support surface 8 against the Roller 4 pressed.
  • the roller 4 can be heated to the Lane 2 not only with the raised one in Breitnip 6 Pressure, but also with an elevated temperature to act upon.
  • the support surface 8 can have a curvature have adapted to the curvature of the roller 4 is.
  • the Breitnip 6 has an active length of at least 40 mm, i.e. the web 2 is in the Breitnip 6 on a length of at least 40 mm with increased pressure and increased Temperature applied.
  • the band 5 can be the jacket of a so-called shoe roller his. In this case it is relatively stiff but elastic enough to adapt to the curvature of the roller 4. Band 5 can also be used as a flexible band be trained, as shown, over several Backing rolls 9 is circulated.
  • the web running direction 10 runs from left to right.
  • the web running direction 10 is marked by an arrow.
  • a heating device 11 arranged with which the web 2 pre-dried becomes. In Breitnip 6, however, the web 2 should still have some moisture.
  • the Application device 12 coats the web 2 with a Coating made of glue, starch and / or pigment.
  • the Stroke is sometimes referred to as a coating color.
  • a further drying device 13 is provided, with the help of which the web 2 can be dried in order to dry the stroke. Accordingly, behind the Drying device 13 another application device 14 may be provided in which another stroke can be applied. In the application device 12 accordingly, a primer can be applied, while in the application device 14 a repaint is applied.
  • the application device 12 as a contour line application device is trained. At a Contour line does not equalize the surface of the web, such as a blade stroke.
  • the So coating color is not by a squeegee or a Scraper smoothed. While this would be a relative one bring smooth surface with it. When printing one Such a surface can cause problems which are called "pressure mottling".
  • a contour stroke on the other hand, there is a coating applied to the surface of the web 2, the one has uniform thickness and the contour of the surface Lane 2 follows.
  • the surface of the stroke has in Basically the same or at least a similar structure like the surface of the web 2 itself you buy reduced smoothness. The printability but will be significantly improved.
  • the application device 12 is as Roll press formed with two rolls 15, 16, wherein each roller 15, 16 cooperates with a nozzle 17, 18, which a "film" on the surface of the rollers 15, 16 applying. This film is then transferred to the train Second
  • FIG. 2 shows an alternative embodiment of the application device 12, where the line through spray nozzles 19, 20 applied directly to the surfaces of the web 2 becomes.
  • designated order device 12 can in principle achieve an ideal contour stroke in which a capillary penetration of the coating into the surface the lane 2 takes place. You can also get one here Omit spray nozzle if only one-sided application the stroke is desired.
