Definitions

  • the invention relates to a device for direct or indirect, one or both sides Apply a liquid or pasty medium to a running surface according to the preamble of claim 1.
  • roller applicator Such an applicator, called roller applicator, has become known from DE 3605409.
  • Such application unit belongs to the group of the L ong D well T imeApplikatoren, ie applicators with l anger E inwirk z eit.
  • the object of the invention is therefore to apply the application medium with a suitable device, to be distributed evenly across the machine width.
  • the scoop roller of the roller applicator is in the direction of travel of the material web or upstream of the applicator roller, a nozzle applicator.
  • the scoop roller and the nozzle application device are the same application roller or counter roller (in the case of direct application, this is partially wrapped in the paper web) assigned. This results in a compact arrangement that takes up little space requirement.
  • the nozzle applicator can be a free jet nozzle applicator known per se be, as is already known from WO 95/12031, and a machine-wide metering gap having.
  • the nozzle applicator can also be an applicator, where from a variety the application medium from individual nozzles evenly distributed over the width of the machine is applied to the running surface.
  • the arrangement of the nozzles is such that those emerging from the nozzles Radiate on the running surface in their end areas and thus a complete covering of the current surface with the application medium to guarantee.
  • a pre-coat should be applied to the running surface with the nozzle application device provided.
  • the main part of the line is done by the scoop roller. Excess medium applied in this process is then scraped off using doctoring devices known per se.
  • This variant is particularly applicable where such a roller applicator already exists is present in the paper machine or finishing machine.
  • the coating machine easily with the nozzle application device, in particular the Retrofit free jet nozzle applicator.
  • the scoop roller then no longer has to perform its actual function, namely the scooping and application of the application medium.
  • the scoop roller can then be used in the variant with individual application nozzles to equalize or even out the line application. In this way, the overlapping or penetrating end regions of the individual jets in the nip between the scoop roller and the running surface can advantageously be compensated for by rubbing.
  • the roller runs in the opposite direction to the running surface at a lower peripheral speed than this.
  • the scoop roller which is no longer scooping, can run in the same direction (clockwise). In this case, i.e. in the case of equalization, it does not need to be driven at all.
  • the applicator shown in Figure 1 comprises a scoop roller 1, which in one Swamp 2 of application medium M revolves.
  • the swamp is in a trough with Collecting pan 3.
  • the scoop roller 1 is a counter roller as a so-called running surface 4 assigned, which is wrapped in a paper web B. Both rollers 1 and 4 run in opposite directions. Together they form a nip N, in which the application medium is delivered directly to paper web B.
  • a round machine-wide ink feed pipe 7 is selected, into which a large number of individual nozzles 8 arranged distributed over the length of the tube 7 are.
  • a primer can be applied to the paper web B, whereby the bulk of the order is then done with the scoop roller.
  • the whole can also be used with the nozzle application device 6 Stroke can be applied.
  • the scoop roller 1 is not an application medium fed, but it is transformed to a certain extent by the previously applied layer evened out.
  • the scoop roller rotates in the same direction, to achieve a better rubbing effect (see dashed arrow in Figure 1).
  • the scoop roller 1 has a doctor device 5 is subordinate.
  • This is a known device with a doctor blade, a doctor rod or a fixed squeegee bar.
  • Figure 1 is a doctor blade as an example shown the, if necessary, scrapes excess medium from the paper web B. The excess medium is in a collecting trough, not shown in the figure caught and can in the circulatory system the coating process again be fed.
  • FIG. 2 There are two from FIG. 2, in which the indirect application to the paper web is shown Application rollers 10, 10 'can be removed, which together form a nip N through which the Paper web B is running. In this nip, the application medium is transferred to the paper web.
  • Each application roller is assigned a scoop roller 1 or 1 'with a trough 3 or 3'.
  • a nozzle application device 6 or 6 ' is the current one in the running direction Surface (here the application roller 10 or 10 ') in front of the scoop roller in a small amount Spaced from her.
  • FIG. 1 A material web B running upward is shown in FIG.
  • This version shown is only an example and is intended do not limit the scope of the invention.
