Definitions

  • the invention relates to the web guide after a coating device and in a downstream dryer section which has suspended and infrared radiation dryers.
  • a coating device is known from German Offenlegungsschrift 39 10 898.
  • the combined use of infrared radiation and floating dryers is known.
  • the object of the invention is based on the problem, after the process of coating a paper or cardboard web, after the web has a relatively high moisture content of approx. 30%, to provide a web guide for drying the same so that the web first stresses as little as possible and secondly, as little as possible tends to form folds, particularly in the longitudinal direction.
  • a bar-shaped box-like blowing device can be provided in front of the deflection device, which blows air jets onto the web directed against the outside of the web arch.
  • This bar-shaped device can preferably be curved, in addition to which a stronger blowing effect is also produced at the center of the web than at the edges of the web, so that the web receives a greater deflection in the middle than in the edges and thereby produces a spreading effect.
  • drying is carried out to a large extent, with the infrared radiation dryer and the floating dryer alternating, an optimal, maximum drying being able to be achieved in the shortest distance.
  • An alternating arrangement of levitation and infrared dryers is known from EP 0291832, but not for the purpose of web smoothing by undulating web guidance according to the invention.
  • the floating dryers are therefore deliberately designed in such a way that the web is not undulated, but is guided at a very precise distance from the infrared dryers in order to optimally utilize their heating power.
  • a floating dryer is arranged after each infrared dryer to remove the water vapor that forms under each infrared dryer. The dryers are only assigned to one side of the web.
  • the invention provides a longitudinal stiffness (waves in the longitudinal direction of the web) during the initial drying - i.e. in front of the after-dryer group formed with drying cylinders - a stiffness in the transverse direction of the web, so that the ripple in the transverse direction of the web is reduced and wrinkles are avoided.
  • Fig. 1 the web B is passed through a coating device which e.g. has two press rolls 12 and 13, each of which is assigned an application device for coating compound (coating slip) 51 and 52, respectively.
  • the direction of the vertical is indicated here by V and extends essentially parallel to the long edges of the drawing sheet.
  • the web is guided downwards after the coating device and first reaches an air pressure-based web stabilization device 6 and also an air-based web deflection device 2, which has blow nozzles 21 arranged next to one another in an arc. Due to the web tension and the air pressure of the blown air of the web deflection device 2, the web is continued in a contactless manner and first arrives at a floating drying device 3, which also shows blowing devices 23.
  • the blowing devices 23 of the two levitation drying devices are arranged offset from one another, so that, as is known, the web assumes a sinusoidal course.
  • the temperature of the blowing air is between 150 ° and 300 °, but in this case it can also be at room temperature. In this case, of course, this is not a floating drying device but simply a floating web guiding device. However, it is also preferred to work with considerably warmed air here, so that the web is already dried.
  • blowing devices have lateral slots for the exit of the air, which run next to the pressure surfaces 31 for the air cushion. Air is removed again between the blowing devices (see US 4,833,794).
  • the wavy guidance of the web in this area is intended to prevent the waves generated by the transverse shrinkage of the web which is relatively moist after the coating device from enlarging or forming into folds. Also by the action of the web stabilizer 6 and the non-contact web deflection device 2, this ripple based on the expansion of the web should be greatly reduced in the transverse direction.
  • an infrared drying unit 4' is provided, which in turn is followed by floating dryer 3 '', 3 ''' 'with blowing devices arranged offset in relation to one another in the course of the web.
  • This blowing device is essentially designed as a box or bar-shaped.
  • the waviness of the web in the floating dryers 3, 3 'or 3' 'or the sine wave should have a length between 20 and 60 cm, preferably between 20 and 40 cm.
  • Fig. 2 it is indicated that floating drying units 3 and infrared units 4 are arranged alternately, the final infrared unit with I2 and the last floating drying unit with S2 are designated.
  • the web is then deflected on a spreader roller 16 and guided to the first drying cylinder 15, to which further drying cylinders are connected in a known manner.
  • the angle at which the web is guided upwards after the deflection is preferably between 40 and 65 ° to the vertical V.
  • the first blowing device 23 of the floating outer device blows radially from the outside against the convex side of the web B, so that the web - or its course - is also well fixed at the end of the arch.
  • the non-contact web deflection device 2 is curved so that the web is deflected further in the middle of the deflection sheet than towards the edge of the web. Furthermore, the blowing pressures in the middle are chosen to be stronger than towards the edge, so that the web assumes the shape indicated by the dot-dash line in an exaggerated representation. This additionally improves the effect of reducing the wave formation of the web transverse to the course of the web and eliminating the formation of wrinkles. The curvature is of course a little exaggerated here.
  • the difference in blowing pressures between the center and the edge should be approximately 20% and the curvature of the web deflection device should be between 5 and 10 times the web width.
  • the deflection device 2 ′′ with blowing nozzles according to FIG. 4 also has blowing devices 21 ′ radially on the outside of the web arch; if hot air is used in this case, the web drying can begin here, on both sides.
  • the float dryers are numbered 66 to 68 and 66 'to 68', the infrared dryers 69 and 70, storage chairs for the coating rollers 12 and 13 with 61 and 62 and the machine base with 63.
  • the contactless deflection device 2 is mounted on the machine foundation by means of bearings 64.
