Definitions

  • the invention relates to a device for extracting an air boundary layer of a running, deflected by a roller material web and a device for coating a moving material web with such a suction device.
  • curtain coaters For coating of running webs such as paper or board webs, plastic or metal foils, so-called curtain coaters are known in which the coating material (adhesive dispersions, pigment coating, etc.) is applied from a slot in a free-falling curtain on the web.
  • the coating material adheresive dispersions, pigment coating, etc.
  • the air boundary layer adhering to the web causes problems, especially at high web speeds of more than 400 mlmin.
  • the air boundary layer adhering to the web causes irregular fluctuations of the curtain and leads to trapped air which leads to unevenness in the coating thickness.
  • a curtain coater for the production of photographic materials in which in front of the slot nozzle, a shield-shaped element ("air shield”) is arranged, which serves to remove the air boundary layer.
  • the element is arranged in the region of a deflection roller for the web and extends arcuately curved over a certain angular range of the guide roller.
  • the element is designed so that in the inlet area and the outlet area zones are determined in which the air resistance is greater than in a zone between the two areas. In the zone between the areas with greater air resistance, there is a chamber connected to a suction pump to reduce the pressure is.
  • the distance between the sealing elements at the inlet and outlet side and the guide roller is between 0.5 mm and 2 mm.
  • the distance between the outlet end of the shield-shaped element and the curtain is between 5 mm and 30 mm.
  • the invention has for its object to provide a device which makes it possible to reduce the air boundary layer of a wide (3 m and more) web at high web speeds (1000 m / min and more) so that a subsequently arranged curtain coater evenly apply the coating material.
  • the coating device shown in the figures is used to apply a dispersion adhesive (eg an acrylate) in aqueous solution to a siliconized paper web 1. Because of its advantageous properties, the device can also be used for applying other dispersions on paper, plastic films or use thin strips or to coat paper or board webs with coating color.
  • a dispersion adhesive eg an acrylate
  • the coating apparatus includes a slot nozzle 2 which is suspended above the run of the web 1 in a rack.
  • the slit nozzle 2 is connected to a supply for coating material and has on its underside a slot-shaped opening from which the coating material emerges and forms a free-falling curtain 3, which falls on the web surface.
  • the width of the slot nozzle 2 is greater than the width of the web 1 to be coated.
  • the web 1 is deflected by a deflection roller 4 which extends in its axial length over the entire working width of the coating device, i.e. the maximum width of a web 1 to be coated, extends.
  • edge troughs 5 are arranged below the slot nozzle, which limit the curtain 3 to the desired coating width.
  • the edge troughs are each attached to the frame of the nozzle 2, so that they are moved in a displacement of the nozzle 2 in or against the running direction.
  • the coating material separated off at the edges of the curtain is collected and removed against the running direction of the web in a drip pan 6.
  • the drip pan 6 is arranged immediately in front of the deflection roller 4.
  • the slot nozzle 2 is in its working position above the guide roller 4 ( FIG. 1 ) or just behind it ( FIG. 3 ) emotional.
  • the embodiment according to FIG. 1 serves to apply a coating with a width less than the web width. On the coated web 1 so remain coating-free edges.
  • the web 1 is coated over its entire width.
  • the curtain 3 is wider than the web 1.
  • the slit nozzle 2 is located in its working position at a distance behind the apex line of the guide roller 4, so that below the curtain 3, a trough 7 can be arranged, from which the laterally collected next to the web edges coating material becomes.
  • the web 1 is guided horizontally in the region below the slot nozzle 2 and then deflected downwards by a second deflection roller 8.
  • a suction device is arranged at a small distance in the web running direction in front of the slot 2, which in the Figures 2 and 4 is shown enlarged.
  • a suction box 8 is arranged, which is the guide roller 4 - ie to the web 1 - open and connected via at least one opening into the rear wall suction line 9 to a suction fan.
  • the suction box 8 extends in its width over the entire axial length of the guide roller 4. At its inlet side, it has an inlet seal 10 and at its outlet side an outlet seal 11 which extend over the axial length of the guide roller 4 and with the web. 1 form a gap 12, 13. At least the end of the inlet seal 10 and the beginning of the outlet seal 11 are located in the deflection of the web 1 on the guide roller 4.
  • the suction box 8 includes a frontal seal 14, which is parallel to the outside of the front side at a small distance from this extends.
  • the sealing elements 14 extend with a width of at least 10 mm, preferably more than 15 mm, measured radially to the deflecting roller 4 into the frontal region of the deflecting roller 4.
  • the outlet seal 11 is arranged and designed so that an outlet gap 13 forms with the web 1, the height and length measured in the web running direction over the entire width of the suction box 8, ie over the entire axial length of the guide roller 4, is substantially constant.
  • the length of the outlet gap 13 is more than 10 mm, preferably more than 30 mm, in particular 50 mm - 70 mm.
  • the height of the outlet gap 13 is chosen as a function of the web speed so that the value of the product web speed (in m / min) x gap height (in mm) is less than 1500. At a web speed of 1000 m / min, the gap height is thus less than 1.5 mm.
  • the measured over the roll circumference distance between the end of the inlet seal 10 and the beginning of the outlet seal 11 is 50 mm - 500 mm.
  • the air boundary layer is sucked by the negative pressure in the suction box 8 of the web 1. It has been found that the suction is improved when the inlet seal 10 and the outlet seal 11 are designed so that they each have a sharp edge at its inlet and outlet ends.
  • At least the outlet seal 11 is therefore at its inlet and designed their sharp-edged outlet, preferably, the inlet seal 10 at least at its outlet end on a correspondingly sharp edge.
  • wall 15 is arranged, which extends across the entire width of the suction box 8.
  • the wall 15 is formed by a perforated plate which separates the rear region of the suction chamber 8 with the suction line 9 from the front region, which is open to the web 1 out. The wall 15 additionally stabilizes the construction of the suction box 8.
  • a corona charging electrode 16 is arranged in the suction box 8, which is connected to a high voltage source.
  • a corona charging electrode and its use for peeling off a gaseous laminar boundary layer is described in detail in US Pat EP 0837824 B1 described.
  • the charging electrode 8 extends across the width of the suction box 8 and has a series of parallel aligned tips 17 which are directed towards the web 1.
  • the applied high voltage causes 16 emerge from the tips 17 of the charging electrode electrons or positrons, which generate turbulence in the air boundary layer and thus stir it up.
  • the tips 17 extend as close as possible to the web 1, wherein the distance to the web 1 0.1 mm - 10 mm, preferably 1 mm - 5 mm. The distance across the web 1 between two tips 17 is about 5 mm.
  • the coating device shown in the suction box 8 is in each case arranged so that the distance from the end of the outlet seal 11 to the exiting the slot 2 curtain 3 10 mm - 200 mm, preferably 20 mm - 70 mm. At this distance, on the one hand ensures that no new disturbing air boundary layer builds up on the way the train to the curtain 3, on the other disturbances of the curtain 3 are avoided by sucking air into the outlet gap 13.
  • Suction box 8 shown formed extended at its end. The end of the suction box 8 with the outlet seal 11 extends over the apex line of the guide roller 4 of time.
  • the upper boundary of the suction box 8 is designed so that it protrudes only slightly over the circumference of the guide roller 4 upwards. This makes it possible to arrange the edge troughs 5 above the suction box 8 immediately above the web run so that they run slightly downwards against the web running direction, so that the collected coating material runs into the trough 6.
  • the suction box 8 is pivoted away from the deflection roller 4, so that a new web 1 can be introduced into the coating apparatus. In addition, its open to the web 1 front is accessible for maintenance.
