Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a curtain delivered by the applicator is to be kept stable over its entire width, so that the curtain in closed form, without the influence of harmful air inclusions, over the entire Web width ensuring uniform order result.
  • This requirement is the more difficult to realize the faster the fibrous webs run in the machine. It is also dependent on the quality of the fibrous web and the application medium.
  • the curtain coater is arranged at a predetermined distance from the web side of the fibrous web to be coated and discharges the application medium, consisting for example of pigment-containing coating color, as a substantially gravitationally moving curtain from a machine-wide slit nozzle.
  • the coating with this commissioned work takes place without excess of medium. This means that only as much medium is dispensed and applied to the fibrous web as to remain on it in the end.
  • the curtain produced by the commissioned work is therefore less voluminous and very sensitive, especially to incoming air boundary layers.
  • the post-published DE 103 58 508.7 also deals with the problem of the harmful influence of air boundary layers flowing to the coating unit with the high-speed fibrous web.
  • an air boundary layer control device for air boundary layers flowing with the fibrous web is arranged on the web side opposite the coating side.
  • This control device is assigned to a longitudinal track section, which passes through the moving track and in the area of which the impact position of the curtain is located on the opposite side of the track.
  • the proposed air boundary layer fighting device can be made as a structural unit, consisting of a support body and arranged thereon acting in the direction of the web underside Beerabstreifaffn.
  • the squeegee are flexible. Ideally, they do not or hardly touch the fibrous web.
  • this control device is disposed on a present below the fibrous web catcher for the curtain.
  • the device is characterized compact.
  • an existing collecting device which is provided for collecting medium parts of the curtain outside the width of the fibrous web, so for collecting the dispensed side edges of the curtain during the operating phase of the commissioned work and / or a web break, simultaneously is designed as air boundary layer removal device.
  • the catcher then has side walls which act as baffles, whereby in the operating phase of the applicator the incoming air boundary layers can be stripped and directed outwards to a location where they are harmless.
  • the complete catcher is designed swiveling.
  • a height-adjustable squeegee strip on the inlet side (this is the side to which the fibrous web in its Running way tapers) of the collecting device is arranged.
  • the distance between the upper edge of the squeegee is motorized, but also manually adjustable.
  • the collecting device is formed like a trough with respectable height.
  • the collecting device can be designed in a simple manner in terms of flow, so that its inlet side (which is also the side on which the fibrous web tapers to it) can act as a guide surface for deflecting the air boundary layer.
  • the collecting device has a continuous fibrous web substantially parallel upper edge or upper edge surface. This upper edge is very close to the fibrous web, that is arranged at a distance a between about 0 and 3 mm. It is an arrangement at a distance, an arrangement with contact or an arrangement with "immersion" (up to -1 mm) in the web possible. As a result, it is particularly prevented that the air boundary layer can be formed again.
  • the collecting device is arranged in the region between two bodies which convey the fibrous web to the applicator unit and which are again guided away from the applicator unit and optionally deflected. At a particularly small distance a the fibrous web undergoes a certain support in the area of the curtain applicator.
  • at least one side wall of the collecting device should reach up to at least one of the body or guide body, which has a particularly favorable effect on the running behavior of the web in the region of the guide body. Air boundary layers can thus not crowd between the guide body and the web, which in turn has a positive effect on the running behavior of the fibrous web in the further path through the manufacturing and / or finishing machine.
  • the bodies or guide bodies are each designed as rotating rollers. As center distance from each other 400 to 2000mm, preferably 500 to 1200mm provided.
  • the Body formed as guide rollers are adjustable relative to each other in height, so that a sloping or rising guide the fibrous web at an angle ⁇ between 10 and 40 ° can be achieved. Such a slope (+/-) has been found to be particularly effective at depositing the curtain on the fibrous web.
  • An increasing web guide brings advantages in terms of preventing the entry of incoming air boundary layers on the coating side, while a falling web guide causes an additional stretching of the curtain when depositing on the fibrous web and thus an improvement in the quality of the application layer.
  • the arranged in front of the curtain relatively large guide roller already acts as an air barrier barrier.
  • the rotatable designed as rollers and possibly as suction rollers guide body can also be provided that at least one guide body is formed as a stationary element.
  • a known Airturn for contactless guidance and deflection of the fibrous web is suitable.
  • An advantageous embodiment may be that the collecting device is equipped with a hinged Gutgrenz für- squeegee, which faces the inflowing air boundary layer. Such an embodiment is easier to produce than the production of a specially designed as a bulkhead sidewall.
  • the entire catcher, as well as the squeegee can be designed as swung off. This is useful for service purposes, above all, space is created when in this area a new train pulled, i. must be transferred.
  • FIG. 1 It is shown how a running in the direction L fibrous web 1 coming from above a first body 2 for guiding and deflecting the web. Then, in a distance 3 sloping at an angle ⁇ of about 15 °, the web 1 passes to a second body 4, from which the web 1 runs downwards to further treatments, such as drying, smoothing, further coatings, rolling up, etc.
  • Both bodies 2 and 4 are guide bodies for the fibrous web 1. They could be called so-called standing airturns, as in the FIG. 6 a to d is shown to be formed.
  • FIG. 1 but are provided for rotating rollers whose diameter is between 400 and 800mm. Due to their diameter, these, in particular the first roll 2, are suitable for use as air-boundary layer control systems. or removal device to be able to act on the coating side 1a.
  • the coating side 1 a within the distance 3 a machine-wide (adapted to the width of the fibrous web) curtain applicator unit 5 is arranged, which emits a vertically downwards and freely falling curtain 6 on the coating side 1 a.
  • This curtain 6 strikes in a position P or in a point of impact or impingement on the fibrous web and deposits there as a coating layer in the desired thickness.
  • various devices are provided with which the penetration of disturbing air boundary layers in the direction of the curtain 6 is prevented or minimized. Namely, if the curtain 6 is not stable and does not form a uniform and continuously closed veil (without air pockets), then the coating layer is then not even.
  • These devices are in the running direction L of the fibrous web 1 before and after the curtain 6 and the web - i. Coating side 1a assigned.
  • These so-called air boundary layer weakening or removal or control devices are designed in the form of the first roller 2 and at least one sealing strip 7 arranged downstream of the roller 2. After the curtain is on the same side of the web 1a a vertically Asked and approximately the length of the curtain 6 representing protective wall 8 is provided, which also still disturbing air boundary layers -something caused by pumping effects of the fibrous web- prevented.
  • a collecting channel for the start and stop phase of the commissioned work 5, which can be moved in and out of the curtain 6 in the direction of the double arrow, is shown here.
  • the starting chute is in the retracted state above the second guide body. 4
  • the opposite web page 1b is within the distance 3 in the region of the impact point P, a further air boundary layer weakening or control device 10 is present.
  • FIG. 1 It is shown that this is attached in the form of a wiper strip 10a on a trough-shaped collecting device 11 for collecting discharged substantially outside the width of the fibrous web 1 side edges of the curtain 6 at its inlet-side side wall 11a hinged. With dashed lines and double arrow folding down the squeegee 10a and the entire pan 11 should be shown.
  • the outlet-side side wall 11b of the collecting trough 11 is adapted to the outer shape of the body 4, ie the roller 4 and with its upper side 11c facing the fibrous web side 1b extends far into an existing gusset 12 between the roller 4 and the web side 1b.
  • the gusset 12 is protected from inflowing air boundary layer LG, whereby the running behavior of the fibrous web 1 is improved and the web web shown further down can be made to further treatment steps trouble-free.
  • the curtain 6 remains stable in the region of its impact at position P and thus ensures a high quality of the application layer 13 depositing on the fibrous web.
  • FIG. 2 also shows a coming from above fibrous web 1, which in turn tapers the first body or the roller 2 for guiding and deflecting the web.
  • a curtain applicator 5 is assigned above the fibrous web 1 and the web page 1a. Dashed lines and arrows show that the commissioned work can be adjusted horizontally and / or vertically. This is in addition to the mobility for service purposes especially the impact angle ⁇ of the curtain 6 on the fibrous web 1 adjustable.
  • the fibrous web 1 runs in a distance 3 rising at an angle ⁇ of approximately 30 ° to the second guide body or a second roller 4.
  • both rolls 1 and 4 are made with a relatively large diameter whose size is about 400 to 800mm. Therefore, the first roller 2 is able to keep air curtain boundary layers LG reliably from the curtain on the coating side 1a.
  • an air cushion LP can form on the surface of the roller 4, so that in the case of the arrangement of the commissioned work 5 above the roller 4, the side edges of the curtain, which are delivered outside the web width, yet not the surface of the Can contaminate roller 4.
  • the curtain side edges lie on the air cushion LP and are derived with the air cushion, in particular guided into a gutter. If there is no or only insufficient air cushion, the curtain side edges lay down on the roller 4 and must be scraped free with blade elements.
  • a collecting device 11 is arranged below the fibrous web 1 and the web page 1b below the fibrous web 1 and the web page 1b.
  • This collecting device 11 is designed such that it simultaneously acts as an air boundary layer control device 10 against the air boundary layers LG flowing with the fibrous web 1 on the side facing away from the curtain 6 b side.
  • the collecting device 11 is also trough-like with a continuous fibrous web 1 substantially parallel upper edge 11 c formed. This upper edge 11 c forms with the web side 1 b a distance a between 0 and 3mm.
  • the device 11 can therefore touch the web 1 or even dip into a minus region of about 1 mm, without scratches on the web, abrasion dust and electrostatic charges are generated.
  • the collecting device 11 in the region between the two, the fibrous web 1 leading and here also deflecting bodies / rollers 2 and 4, ie within the distance 3 and below the impact position P of the opposite curtain 6 is arranged.
  • At least one side wall of the collecting device 11, namely the outlet-side side wall 11 b and also a scraper plate 11 d attached thereto extends into the gusset 12 between the roller 4 and fibrous web side 1b.
  • the collecting device 11 is dimensioned longer than the web 1 is wide.
  • the height of the collecting device 11 corresponds approximately to the size or the diameter of the second body. 4
  • Nachzutragen is still the center distance between the two guide or deflecting bodies 2 and 4, which is about 400 to 2000 mm.
  • the height of both bodies can be adjusted in such a way that the in FIG. 1 shown sloping or the in FIG. 2 shown rising leadership of the fibrous web 1 is reached.
  • FIG. 2 is still located above the coating side 1a arranged side plate 14. This is present on both sides of the machine and also serves to prevent inflowing air boundary layers LG in the direction of the curtain 6. His the curtain 6 end facing away from the curtain 6 at a distance b of about 30 mm. Its underside, which faces the web side 1a, has a distance c of 0 to 3mm. These dimensions ensure avoidance of the rebuilding of air boundary layers and thus contribute to the fact that the curtain can fall on the fibrous web 1 uninfluenced by harmful air influences.
  • the air boundary layer fighting device 10 is manufactured as a separate component of the catcher 11. At the web inlet and the web drain side are flexible squeegee 10 a, ideally not the fibrous web base 1b to touch, arranged.
  • the device 10 could additionally be equipped with an air suction, not shown.
