- the invention relates to a device for applying liquid or pasty application medium by means of an application work on a running Underground according to the preamble of claim 1.
- curtain applicator also known as “curtain coating”
- the application medium to the surface in the form of an application medium curtain issued, which is due to gravity from Commissioned work moved to the underground. That the curtain commission is at a predetermined distance from the surface Among other things, it has the advantage that it breaks down, for example is exposed to a lower risk of damage.
- Curtain coaters differ from other "contactless" commissions, for example free jet nozzle applicators, in which the movement of the order medium from the order work to the underground mainly comes from the ejection impulse from the delivery nozzle of the application unit, fundamental since the shape of the emerging from the dispensing nozzle Curtain only the interplay between the surface tension of the application medium and gravity.
- the surface tension tries to make the curtain based on its volume or its cross-sectional area has a very large surface or Has circumferential length to contract so as to its surface reduce. Only gravity opposes this effect Tries to stretch the curtain. It is therefore easy to see that it is all the more it is more difficult to have a uniform thickness across the entire working width Obtain the gas medium curtain the larger this working width.

In addition, this distance X even with the machine at a standstill or at low web speeds be given. Basically, however, is also one dynamic sealing possible, in which the sealing plate section 782c only when starting the machine, i.e. with increasing web speed is lifted off by a part of the air boundary layer G, whereby the desired distance X, however, at the latest when the operating speed is reached established. Because of the latest in operation non-contact sealing can also be set in this If there is no abrasion.
- the sealing device 780 prevents that a larger proportion of those carried along by the material web 720 Air G in the area of the impact position P, not shown in FIG Order medium curtain arrives.
- the air boundary layer G entrained by the material web 720 thus becomes largely scraped or stripped.
- Another advantage is too call that the sealing plate portion 782c on the surface of the Material web 720 carried impurities without further notice can dodge. And also in the event of a web break and "packing up" the Back-up roller 774 is at risk of damaging the sealing device 780 reliably prevented.
