Definitions

  • the coating colors contain chalk, calcium carbonate etc. as pigments, and additives such as CNC, starch and auxiliaries are also added.
  • the main application DE 197 16 647 has a method and an apparatus for
  • a pigment coating ink to a paper or cardboard web, in which the coating ink with a solids content of 30% by weight to 72% by weight is applied to the free-falling curtain by means of a slot nozzle which is arranged above the web and extends transversely to the web running direction Web is applied.
  • the application in a free-falling curtain has the advantage that an application without excess and thus without stress by a subsequent metering element is possible even with a very low coat weight.
  • guide elements are arranged at both ends of the exit slit of the slot nozzle which extend down to near the web and counteract a constriction of the edges of the free-falling curtain.
  • Guide plates are preferably used as guide elements.
  • a generic method for applying a pigment coating ink to a paper web in a free-falling curtain is known from EP 0 517 223 B1. This document does not address the problem that the curtain tends to constrict.
  • the auxiliary liquid forms a triangular, flat, stabilizing liquid bridge between the curtain and the curtain holders.
  • the invention has for its object to improve the stability and uniformity of the curtain in a generic method for applying a pigment coating ink on a paper or cardboard web.
  • Another object is to provide an apparatus for carrying out a method according to the invention.
  • the first task is solved with the features of claim 1, the second task with the features of claim 4.
  • FIG. 1 shows a cross section through a loading device transverse to the direction of web travel
  • FIG. 2 shows the edge region of FIG. 1 in an enlarged representation
  • FIG. 3 shows a side view of the device according to FIG. 2
  • FIG. 4 shows a further enlarged illustration of the edge area in the impact zone of the curtain on the web
  • 5 and 6 show alternative embodiments of an element for separating the curtain edge.
  • the device shown in the figures is used to apply a water-based pigment coating color with a solids content of 30% by weight to 72% by weight, preferably 45% by weight to 70% by weight, on a paper or cardboard web 1. It points out the essentials Part of a slot nozzle 2 which is suspended in the frame of the device extending transversely to the web running direction (arrow 3 in Figure 3).
  • Slot nozzle 2 is connected to a feed, not shown, for coating color and has on its underside a slot-shaped outlet gap 4, from which the coating color emerges and forms a free-falling curtain 5, which falls onto the surface of the web 1.
  • the shooting nozzle 2 is suspended in a height-distributable manner in order to be able to adjust the distance of the outlet gap 4 from the web 1 and thus the drop height of the coating color.
  • the web 1 is deflected and supported by a deflection roller 6 so that it runs very smoothly and thus order fluctuations when the curtain 5 impacts the web 1 are prevented.
  • a guide element 7 is attached directly next to the exit gap 4, which extends downwards into the vicinity of the web 1.
  • the guide element 7 has the task of guiding and spreading the curtain 5 at its edge in order to counteract a constriction due to the surface tension.
  • Each guide element 7 is flat on its inner side 8 facing the curtain 5, the inner surface 8 is preferably flat with a width of more than 10 mm, preferably approximately 20 mm, measured in the web running direction 3. Alternatively, it is also possible to design the inner surface 8 in a concave or convex shape, the axis of curvature being perpendicular. Runs from the nozzle 2 to the web 1 the inner surface 8 of the guide element 7 is inclined at an angle between 0 ° and 10 ° to the center of the curtain 5.
  • Each guide element 7 is preferably rigid, as shown in the figures.
  • either the entire guide element 7 or only its inner surface 8 is designed to be flexible.
  • actuating elements then act on the guide element 7.
  • Flexibly designed guide elements 7 also make it possible to additionally spread the curtain 5 before it hits the web 1 in order to thin the edges. For this purpose, the guide elements 7 are bent outwards in the lower region.
  • each guide element 7, which forms the end of the inner surface 8 is preferably designed as a tear-off edge 9 so that the edge of the curtain 5 leaves the guide element 7 in a defined flow without undesired deflection to the outside.
  • the tear-off edge 9 prevents the so-called “teapot effect", which would cause the curtain edge to be partially deflected around the underside of the guide element 7.
  • each guide element 7 has a through hole which serves as a feed line 10 for feeding a separate partial stream of coating color onto the inner surface 8.
  • the feed line 10 is connected to the paint supply system of the slot nozzle 2 by means of a separate valve via a control valve, so that the size of the partial flow of coating color supplied to the guide element 7 as auxiliary liquid can be adjusted.
  • the feed line 10 opens into the upper part of a feed channel 11 of approximately 20 mm in length, which runs vertically downward above the outlet gap 4, the outlet opening of which is located directly next to the slot 4 at the height of the outlet gap 4.
  • the feed channel 11 is constructed in a structurally simple manner such that a vertical longitudinal groove extending as far as the bore 10 is worked into the inner surface 8 of the guide element 7 in the region of the slot nozzle 2 and is sealed by the latter when the guide element 7 is fastened to the side wall of the nozzle 2.
  • the partial flow of coating color fed to the guide element 7 above and flowing down on the inner surface 8 when it comes into contact with the edge of the curtain 5 - in the example when leaving the feed channel 11 at the height of the outlet gap 4 - is essentially vertically downward directional flow and that the flow rate of the partial flow is at least as high as the exit speed of the coating color from the nozzle 2.
  • the curtain 5 is spread along the edges by the cohesive and adhesive forces which act on the one hand between the coating color of the curtain 5 and the partial flows, and on the other hand between the coating color of the partial flows and the inner surfaces 8 of the guide elements 7.
  • the inner surfaces 8 are therefore designed so that they are easily wetted by the coating color. Spreading transverse forces act on the curtain 5 at its edges without its stability being influenced by decelerating the falling speed or by transverse currents at the edges.
  • the coating color can be recirculated as an auxiliary liquid if a curtain 5 is produced, which is wider than the desired coating width on the web 1.
  • a wider curtain 5 is preferably coated to one over the Coating width to achieve even application.
  • the curtain edges, on which the curtain 5 is thickened, are then separated before hitting the web 1, so that a uniform curtain 5 with the desired coating width impacts the web 1.
  • Each guide element 7 preferably contains a cavity 12 in the interior, which extends in the longitudinal direction over the area of the interior surface 8 that comes into contact with the coating color.
  • a cooling liquid is introduced into the cavity 12 via supply lines in order to cool the inner surface 8, so that caking of coating color is prevented.
  • the inner surface 8 is cooled to a temperature which is approximately 15 ° C. less than the temperature of the coating color.
  • a separating element 13 is arranged between the underside of the guide element 12 and the web 1, which extends from the outside inwards into the area of the web 1.
  • Each separating element 13 covers the respective edge area of the web 1 to be kept free.
  • Each separating element 13 is preferably mounted so as to be displaceable transversely to the web running direction in order to adapt its position to the web width and the width of the edge to be kept free - which can also go to zero can.
  • Each separating element 13 has an upper collecting surface 14, which preferably extends inclined outwards, so that the striking paint runs off to the outside.
  • the collecting surface 14 curves upwards in a sharp separating edge 15 which cuts the curtain 5 at the desired point in the manner of a blade.
  • the end of the guide element 13 directed towards the center of the curtain is formed by a guide surface 16 which is designed to run vertically or inclined downwards to reduce the risk of tearing of the curtain 5 at a slight angle to the center of the curtain.
  • the upper end of the guide surface 16 forms the separating edge 15 with the collecting surface 14.
  • the simplest form of the lower end directly above the web 1 forms a right-angled edge with the outwardly extending lower wall 17, as shown in FIG. 5.
  • the preferred embodiment of the inner guide surface 16 of the separating element 13 is shown in FIG. 4:
  • the guide surface 16 is curved outwards in its lower part and ends at the bottom in an acute-angled tear-off edge 17.
  • the part which is curved outwards becomes the one on the guide surface 16 flowing curtain edge spread outwards, ie pulled apart, without the risk of tearing.
  • the spread reduces the thickness of the curtain edge, so that the layer of coating color applied to the web 1 is uniformly thick up to the coating edge, at least not unacceptable, since a quantity of coating color which can no longer be dried is applied to the web edge by a subsequent dryer.
  • the sharp tear-off edge 18 prevents the "teapot effect", that is to say that coating color runs from the guide surface 16 onto the underside of the lower wall 17 and drips off from it in an uncontrolled manner. This would lead to contamination of the web edges and / or the counter roller 6. If the curtain 5 does not need to be spread between the lower tear-off edge 18 and the web 1, the guide surface 16 can also merge in a straight line into the tear-off edge 18, as shown in FIG. 2.
  • the separating elements 13 preferably have a cavity 20 on the inside, in which the cooling liquid for cooling the coating color in
  • the cooling of the separating elements 13 prevents coating color from baking on.
  • the separating elements 13 are preferably made, at least in their part that comes into contact with the coating color, from a hollow profile with boundary walls that run in a curved manner as described above, so that for cooling there is sufficient heat transfer from the contact surfaces 14, 16, 19 to the inner cavity filled with coolant is guaranteed.
  • this can also be coated on its collecting and drainage surface 14 with a poorly wettable material, for example with Teflon, for a trouble-free discharge of the coating color.
  • each separating element 13 measured in the web running direction 3 is dimensioned such that at least the coating color running off the guide elements 7 is completely caught by the collecting surface 14. To ensure this, the drainage surfaces 14 of the separating elements 13 are wider than the guide surfaces 8 of the guide elements 7.

Abstract

Pour produire des bandes (1) de papier et de carton couché, on applique sur la bande (1) un enduit pigmenté provenant d'une buse en forme de fente (2) sous forme de rideau (5) tombant librement. Selon la présente invention, pour l'écartement du rideau au niveau de chaque bord, un flux partiel séparé d'enduit est amené sur la surface interne (8) d'un élément de guidage (7) de manière que chaque flux partiel soit en contact avec le rideau (5) selon un flux essentiellement vertical orienté vers le bas et avec une vitesse d'écoulement qui est au moins égale à la vitesse de sortie de l'enduit de la buse (2). Ledit élément de guidage s'étend vers le bas jusqu'à proximité de la bande (1) immédiatement à côté de la fente (4) de sortie de la buse. De préférence, un élément de séparation (13) est placé sous chaque élément de guidage (7) pour séparer le bord correspondant du rideau (5) et l'évacuer vers l'extérieur.
