  • the invention thus relates on the one hand to machines which enable the production and treatment, including the application of an application medium, to at least one side of the material web in a so-called online operation.
  • machines of this type only touching application devices are conventionally used as application devices
  • the invention relates to machines which are used for treatment, including application of an application medium, on at least one side of the material web in a so-called offline mode.
  • Such machines are machines separate from a machine for producing the material web (coating or application machine), to which the material web to be treated is generally fed in the form of material web rolls.
  • both contacting application devices are used as application devices (Coating units) and contactless application devices (contactless coating units) are used.
  • Touching application devices can be problematic in that the performance (runnability) and average operating times between business interruptions due to the touching application or coating could be impaired. There is an increased risk of a web break in the coating unit (coating unit), with the result that the entire production line comes to a standstill.
  • offline operation has a lower volume efficiency.
  • the Matenalbahn can be satin-finished online in a smoothing unit, possibly two-roll soft calender, machine-smooth or sharply machine-smooth.
  • material qualities that conventionally have to be satined offline in a further operation after the production of the material web in a corresponding machine or after painting on a coating machine.
  • the satin has a significant influence on the surface structure of the material, especially paper or cardboard, and thus on both the visual impression and the printability. Satinizing is a very important process, especially for coated papers. After painting, it brings smoothness and possibly shine. After brushing alone, sufficient smoothness or gloss is usually not achieved.
  • the object of the invention is to provide a machine of the type mentioned at the outset which has good performance and runnability and Can provide material with high smoothness and possibly gloss with good volume efficiency.
  • the application device comprises at least one contactless application unit which is designed to dispense application medium in at least one free application medium jet or application medium curtain or application medium veil or in application medium spray drops and to apply it to the material web Based on the forces or / and movement impulses given by the application medium and / or on the basis of a movement of the application medium caused by gravity, and that a material web smoothing device is provided along the treatment path before or / and after the application device.
  • an order based on electrostatic forces can be considered, for example.
  • contactless application of the application medium to at least one side of the material web is made possible in online mode or in offline mode in the machine (in particular paper machine).
  • the material web smoothing device integrated in the machine ensures a high level of smoothness and, if necessary, a sheen of the material on one or both sides of the material web.
  • Material web smoothing device also achieves the high smoothness and possibly the gloss of the material online.
  • the machine preferably has a material web smoothing device along the material web path at least in front of the application device.
  • a material web smoothing before the application of the application medium is particularly expedient and effective insofar as contactless application methods, in particular coating methods, largely retain the contour of the material web surface (in this context, one speaks of so-called contour coating methods).
  • This means that a rough contour of the material web is not or only comparatively little compensated for by the application medium and thus smoothed.
  • the smoother the material web before the application medium was applied the higher the product quality. In this context, it has also been found that it is better to smooth first and then apply the contour stroke than to smooth a rough contour after painting.
  • the material web smoothing device is designed to smooth the material web at least on one side in such a way that a material web roughness of between 5 ⁇ m, preferably of at most 3 ⁇ m, remains.
  • These material web roughness values preferably relate to values determined using the PPS method (Parker Print Surve): roughness (PPS - 10s) ⁇ 5 ⁇ m, better ⁇ 3 ⁇ m.
  • the main consideration is that these roughness values are achieved on the basis of normal operating parameters of the machine.
  • a material web smoothing device can also be provided along the material web path after the application device, for example in order to achieve a particularly high smoothness or a particularly high gloss.
  • a material web smoothing device arranged in front of the application device can ensure sufficient smoothness or a sufficient gloss.

  • at least one contactless application unit designed as a spray application unit is provided, which delivers the application medium to the material web in the form of application medium spray drops or application medium jets, preferably at least predominantly on the basis of the application medium when it emerges from a nozzle arrangement of the application unit movement impulses.
  • the curtain application process is preferred over the spray application process, since a higher product quality can be achieved on the basis of the curtain application process and the curtain application process generally entails less maintenance work than the spray application process.
  • the machine according to the invention can have at least one further material web treatment device.
  • Material web treatment device can be arranged along the material web path between the material web delivery device and the application device or between the application device and the drying device or between the drying device and the device for processing or / and picking up and / or dispensing the material web and, if necessary, can be connected upstream or downstream of the material web smoothing device according to the invention or in the material web delivery device or the application device or the drying device or the device for Processing or / and recording or / and delivery of the material web can be integrated.

  • contactless application by means of an appropriate application device is also particularly advantageous when application medium is applied to the running material web at several application points in the machine.
  • the material web is less stressed by the contactless application of the application medium than by a contacting application, so that the risk of web breaks is reduced and accordingly the performance or runnability is improved.

  • the invention proposes, among other things, to apply contactless painting in a uniform process and to use a suitable smoothing device, in particular a calender, for smoothing, the smoothing being able to take place before or after painting.
  • Smoothing using a calender before painting replaces a conventional smoothing unit, so that a particularly good substrate for painting and an improvement in the final quality (high smoothness or high gloss) are achieved in a uniform process.
  • a very smooth end product is achieved by applying a line of curtains to a very smooth raw material (raw paper).
