- the liquid or pasty medium from an application device directly onto the Surface of the running web of material applied during the application on a rotating counter surface, for example an endless belt or a counter roller, is supported.
- the Application device usually as a pre-metering device designed the liquid or pasty medium initially orders in excess order quantity.
- the pre-metering device is in the direction of travel of the material web expediently a final metering device (also Fine dosing device, finished dosing device or Equalization device) connected downstream, which previously excess applied by the pre-metering device Medium with the help of a running material web pressed, consistently over essentially the entire Web width extending doctor element, such as one Doctor blade, a doctor blade or the like, doctored and so the desired final order quantity on the Material web achieved.
- the final dispenser is common in a variety of cross-directional Zones divided into material web, each zone normally an actuator is assigned so that by a different influence of the Contact pressure of the doctor element by means of a respective one Actuator a desired cross profile of the applied Medium is reached.
- the actuators are mostly operated remotely or by hand, the Control of the actuators based on measured values from the Cross profile of the applied liquid or pasty medium is carried out via a control loop.
- a pre-metering device for this purpose, for example uses a metering gap designed as a free jet nozzle, that between an inlet-side and outlet-side lip formed and in itself transverse to the direction of the web extending zones is divided, with each zone in generally an actuator is assigned so that the lip on the inlet side or the lip on the outlet side the length of the application is uniform or in zones different in their distance from the opposite lip is adjustable. It is also possible to use both lips to adjust at the same time.
- the actuators mentioned are mostly remotely controlled or alternatively by hand press, the actuation of the actuators based on measured values of the cross profile of the applied liquid or pasty medium is carried out via a control loop.

- the final metering device E comprises zones to which either one or two adjusting points are assigned, there are both adjusting point P e of the final metering device E in this configuration, which, viewed in the direction of travel of the material web, lie directly behind an adjusting point P v of the pre-metering device V, as well as adjusting points P e , which are offset from adjustment points P v of the pre-metering device V in the running direction of the material web by a predetermined amount Y in the width direction of the material web.
- the actuators assigned to the zones Z v of the pre-metering device V form at least two divisions which are different from one another due to their respective mutual spacing of their adjustment points.
- FIG. 18 shows a fifth embodiment of the second application unit according to the invention in a representation analogous to FIG. 14.
- the zones Z v and zones Z e of the preliminary and final metering device when viewed in the running direction of the material web, are offset by a predetermined amount x in the width direction of the material web.
- this amount x corresponds to half the zone width b v of the zones Z v of the pre-metering device V, which is smaller than the zone width b e of the zones Z e of the final metering device E.
- FIG. 19 shows a sixth embodiment of the second application unit according to the invention, which corresponds essentially to the variant according to FIG. 18.
- FIG. 20 shows a seventh embodiment of the second application unit according to the invention in a representation analogous to FIG. 14.
- the special feature of this variant is that not only are the zone widths of the zones of the preliminary and final metering devices different from one another, but also the respective zones of the pre-metering device V comprise two different zone types Z v1 , Z v2 , whose zone widths b v1 , b v2 differ from one another are.
- the zones of the final metering device E also comprise at least two different zone types Z e1 , Z e2 , whose zone widths b e1 , b e2 are different from one another.
- the zones Z v1 , Z v2 and Z e1 , Z e2 of the preliminary and final metering device are also offset from one another in the width direction of the material web in this exemplary embodiment.
- the respective zone widths b v1 , b v2 , b e1 , b e2 and the number and arrangement of the adjustment points P v , P e of the preliminary and final metering device are selected such that the adjustment points P e and P v are seen directly in succession in the direction of travel of the material web lie.
- both a first cross profile correction by adjusting the actuators 14 v of the pre-metering device V and a second cross profile correction are required by adjusting the actuators of the final metering device E, the effect of the first and second profile corrections being complementary to a required overall correction of the cross profile.
- a long-wave correction of the cross profile is preferably carried out by regulated adjustment of the actuators 14 v of the pre-metering device V and a short-wave correction of the deviations of the cross profile by controlled adjustment of the actuators 14 e of the final metering device E.
- a short-wave correction of the cross profile by controlled adjustment of the actuators 14 v of the pre-metering device and a long-wave correction of the deviation of the cross profile by controlled adjustment of the actuators 14 e of the final metering device E If predominantly long-wave profile components are to be corrected with the actuators 14 v of the pre-metering device V, fewer actuators 14 v can usually be used than actuators 14 e .
- the actuators 14 v and 14 e of the preliminary and final metering device are integrated in a control circuit, not shown in the figures. The actuators 14 v and 14 e can be adjusted in succession or essentially simultaneously.
- the invention is not limited to the above exemplary embodiments, which only serve to explain the basic idea of the invention in general.
- the application work according to the invention can rather also take embodiments other than those described above.
- the application can have features that represent a combination of the respective individual features of the claims. Configurations are also possible which essentially correspond to the embodiments shown in the figures, although the number and position of the respective adjustment points of the preliminary and final metering device, as is the case in FIGS. 9 and 10, is exactly interchanged.
- the divisions T v and T e explained above can of course also be a non-integer multiple of the other division T e or T v if necessary instead of an integer multiple.
- one or more adjustment points of the final metering device seen in the direction of travel of the material web, can lie directly behind one or more adjustment points of the pre-metering device and / or multiples of the respectively smaller of the mentioned divisions in the direction of travel of the material web can be congruent with the larger of these divisions.
