Definitions

  • the present invention relates to a device for regulating the coating width of a coating to be applied by a curtain coater, comprising an applicator head with an application medium chamber and a dispensing slot extending from the application medium chamber for dispensing a liquid to pasty application medium to a running paper, board or other Fibrous web, wherein at both lateral ends or edges of the discharge slot in each case a limiting element in the discharge slot can be inserted
  • Coated paper such as printing paper, catalog paper, etc., pressure-sensitive paper, thermal paper, etc.
  • Coated paper is produced in an online or offline coater by placing on a die-forming web (starting material) a liquid to pasty application medium, e.g. Coating color is applied and then dried.
  • blade coaters in which the method of replenishment was used, were used as coaters.
  • coating medium e.g., size, thickness, coating color
  • a doctor blade member such as a rod, blade or air knife, that is, brought to the desired coating weight.
  • curtain coating machines have been increasingly used in recent years.
  • the application medium is applied in the form of a curtain from an applicator head from above onto the underlying moving web a curtain layer of paint.
  • curtain coaters lead, unlike conventional coating machines, no additional metering and therefore have no wear parts in the form of doctor elements. This has the advantage that the maintenance is simple, the amount of coating can be easily applied with high precision and the operability is good. In addition, the applied contour line (Contour Coat) shows an improvement in the surface quality.
  • FIG. 3 Shown is a used in the relevant known curtain coater applicator head in section, which in the FIG. 3 denoted by 1.
  • This application head contains an application medium chamber 2 extending in the width direction of the application head 1 into which the application medium, for example coating color, is filled.
  • the application head 1 is assembled from two parts 1a and 1b so that the part 1a has the application medium chamber 2 and the part 1b does not.
  • the application medium chamber 2 is directed downward in an open, located between opposite die lips 1c and 1d discharge slot 3.
  • the nozzle lip 1d is adjustable to adjust the width of the discharge slot 3, wherein the opening or the slot width is 0.3 to 0.5 mm.
  • the nozzle lip 1d is attached to the lower edge of the applicator head part 1b by means of several profile regulating bolts 1 e.
  • a set consisting of the profile regulating bolt 1e or upper pressure bolt 1e, a lower pressure bolt 1g and a middle tension bolt 1f is attached at a distance of about 50 mm in the width direction of the application head. Characterized in that the opening or width of the discharge slot 3 is finely regulated in the width direction, the profile of the color curtain is regulated.
  • the width of the fibrous web to be spread (in particular paper web) is changed relatively frequently. It is necessary, according to the width of the web, the coating width or Ausströmit width of the slot 3 to change.
  • a limiting element are introduced from below and clamped from the outside, so that a leakage in both edges of the slot 3 is prevented and at the same time the falling of the boundary elements is prevented.
  • a lid is inserted from the side and adjusted by moving this cover the width of the outflow from the slot 3.
  • Fig. 4 is one from the Japanese patent 6-198240 known device for regulating the Ausströmbreite shown. This device is shown in the oblique view and in a reversed position by 180 °.
  • a dispensing slot 3 which is connected to the application medium chamber 2 and opens downwards, is likewise present.
  • a cap shaft a is inserted into the application medium chamber 2, and the front edge part b is made of a plastic material and has a liquid-tight structure. In addition, its inner part is hollow, so that application medium can flow into it.
  • the front edge portion d also consists of a plastic material and has a liquid-tight construction and is inserted into the interior of the discharge slot 3. With e the order medium is designated.
  • a disadvantage is that between the limiting element and the opening of the discharge slot 3, a gap remains, can run out of the application medium (leakage) or the limiting element falls out. Therefore, after the restriction member has been inserted, it is necessary to close the gap to rotate a plurality of profile regulating bolts and to move the nozzle lip 1d in the direction of the associated other nozzle lip 1c. This requires a lot of effort. Furthermore, when the nozzle lip 1d is moved, the profile regulation must be performed again from the beginning.
  • the invention has for its object to provide an easier to operate device for regulating the coating width of a curtain coater.
  • the limiting element consists of a flexible plate which can be inserted from below into the discharge slot and zigzag-shaped bendable when inserted into the discharge slot, wherein the thickness of the flexible plate is less than the width of the opening of the Abgabeschlitzes and that a projecting from the discharge slot protruding part of the limiting element is held together with an existing flexible cover of the edge region of the discharge slot on the outer side surface of the applicator head.
  • the flexible plate of the limiting element consists of a plastic material. This makes it very easy that the boundary element are kicked alternately several times can and can be inserted from the bottom of the dispensing slot.
  • the cover is made of a thin, flexible plate made of a plastic material.
  • An advantageous embodiment of the limiting element is that it preferably consists of vinyl chloride.
  • the cover however, preferably made of polypropylene.
  • edge part of the delimiting element and the edge part of the cover are first glued together (this can be done very easily with double-sided adhesive tape) and then fastened together to the outside surface of the application head.
  • This holder can be suitably designed by having a pressure hose.
  • This pressure hose is positioned in existing channels, wherein the grooves are present on both outer side surfaces and arranged horizontally there in the width direction of the applicator head.
  • the holder also has a pressure hose from the outside holding pressure plate.
  • the pressure hose can be filled with air so that it expands and thereby holds the edge part of the limiting element and the edge part of the cover.
  • edge part of the limiting element and the edge part of the cover are clamped very simply and securely between the channel and the pressure hose.
  • FIGS. 1 and 2 are components that come with components from the FIGS. 3 and 4 are identical with the prior art, provided with the same reference numerals.
  • 1 designates the curtain applicator head of the curtain coater.
  • An application medium chamber 2 extending in the width direction of the application head 1 contains the application medium to be applied, for example coating color.
  • 3 of the associated with the application medium chamber 2 downwardly open discharge slot is designated. 4 is a limiting element.
  • This limiting element 4 consists of a flexible plate, made of a plastic material and has a smaller thickness than the opening of the discharge slot 3. If z. B. the opening of the discharge slot 3 is about 0.3 mm, the thickness of the plate or the limiting element 4 is about 0.2 mm.
  • the limiting element 4 is inserted from the lower edge of the slot. In this case, a zigzag shape is formed. To form this zigzag shape, the plate 4 is inserted in the required length in the interior of the slot 3 and protruding from the slot 3 part is kinked by the sharp edge at the bottom of the one nozzle lip 1 d of the paired lips, the Form discharge slot 3, is pressed.
  • the kinked plate or the limiting element is introduced further in the required length in the interior of the discharge slot and the projecting out of the slot part is again, now bent in the opposite direction. This is done by touching the sharp edge of the other lip 1 c the paired lips forming the slot 3 is pressed. Because this process can be done manually and as often as is repeatable, a sealing of the edge regions of the dispensing slot is very easy and inexpensive possible.
  • the remaining after the introduction of the limiting element 4 rest is guided upward and held on the outer side surface of the applicator head 1.
  • the cover 5 is a cover.
  • the cover 5 consists of a thin, flexible plate made of a plastic material.
  • the cover 5 has the same width as the restriction member 4.
  • the cover 5 externally covers the lower edge of the discharge slot 3 at the part where the restriction member 4 has been inserted.
  • the two ends of the cover are also raised as the spacer remainder or guided upwards and held on the outer side surface of the applicator head 1.
  • the holder 6 consists of a pressure hose 6b and a pressure tube holding the pressure plate 6c.
  • the pressure hose 6b is positioned in a groove 6a. This groove runs horizontally along the outside surface of the application head 1 in the width direction, i. transverse to the direction of not marked with the fibrous web.
  • the holder 6 also has a pressure plate 6c which holds the pressure tube 6b from the outside.
  • 6d denotes a fixing bolt for fixing the pressure plate 6c to the outer side surface of the application head 1.
  • FIG. 2 a final plate 10 is shown, which is present on the edge surface of the applicator head 1. In addition, located at the side surface of a feed 11 for filling the application medium chamber 2 with the application medium.
