Definitions

  • the invention relates to methods for the direct or indirect application of a liquid or pasty medium to a running material web, in particular of paper or cardboard, and devices for carrying out the method.
  • the application unit described is a free jet application unit, in which the free jet nozzle is formed by two elongated lip elements.
  • the metering gap of the free jet nozzle ie the distance between the two lip elements, can be set differently zone by zone over the longitudinal extent of the lip elements, that is over the width of the material web to be coated.
  • the application amount of the liquid or pasty medium at the free jet nozzle can thus be metered differently in zones.
  • adjusting devices are provided, which are arranged distributed over the longitudinal extent of the lip elements and which act on at least one of the two lip elements of the free jet nozzle. Furthermore, an automatic control circuit is provided, which adjusts the adjusting devices on the basis of measured values of the cross profile of the applied liquid or pasty medium.
  • the free jet nozzle applicator can also be followed by a fine metering device which can be operated by means of a doctor element, e.g. doctor blade, excess liquid or pasty medium applied to the desired final cross profile.
  • Patent application No. 196 05 183.5 which has not yet been published, describes a method for regulating the transverse profile of the applied liquid or pasty medium over the width of the material web, which relates to a commissioned work, as was explained above. Thereafter, two control loops are provided, of which one control loop effects a first correction of the cross profile directly on the free jet nozzle and the second control loop effects a second and final correction of the cross profile of the applied liquid or pasty medium on the fine metering device. The effect of the two corrections should complement each other to a desired overall correction of the cross profile. Although a desired cross profile is achieved with relatively high accuracy with the aid of this proposed method, in addition to the mechanical effort, the control engineering effort required for this is considerable.
  • the invention is based on the technical problem of creating methods and associated devices in which the regulation of the profile of the applied liquid or pasty medium is simplified.
  • the invention is based on the idea of making a separation of the regulation of the cross profile and the regulation of the longitudinal profile.
  • the transverse profile of the applied liquid or pasty medium is regulated directly when the medium is applied, and the longitudinal profile of the applied liquid or pasty medium is subsequently regulated, that is, downstream in the direction of flow, on the previously applied medium.
  • the longitudinal profile of the applied liquid or pasty medium is regulated directly when the medium is applied, and the transverse profile of the applied liquid or pasty medium is regulated in the direction of flow thereafter on the previously applied medium.
  • the cross profile is controlled by a corresponding zone-wise different dosing during the process of applying the medium, while the longitudinal profile is controlled in a subsequent process on the medium already applied.
  • the longitudinal profile is controlled by a corresponding total dosing during the process of applying the medium, while the transverse profile is controlled in a subsequent process by influencing the medium already applied in zones.
  • the cross profile of the applied medium is the contour of the applied coating over the transverse direction of the material web, that is over the width of the material web.
  • the longitudinal profile relates to the course of the coating in the longitudinal direction of the material web, that is to say in the direction of travel of the material web.
  • the final so-called stroke weight is set for longitudinal profiling. A predetermined average order quantity per material web area for the continuous material web should be adhered to.
  • a transverse profile that is regulated directly when applying the medium is practically hardly falsified by the subsequent adjustment of the longitudinal profile, for example by means of a leveling device, which would be feared. It must be taken into account here that part of the liquid or pasty medium applied with a certain cross profile penetrates into the material web with this cross profile before the leveling device for adjusting the longitudinal profile is reached.
  • the longitudinal profile setting device can therefore no longer change the transverse profile, insofar as it concerns the part of the medium which has already penetrated the material web.
  • a zone-by-zone ie locally different across the web width
  • the control process is thus significantly simplified.
  • the methods according to the invention can be used both in the direct and in the indirect application of a liquid or pasty medium to a running material web, which consists of paper, cardboard, a textile material or the like.
  • a liquid or pasty medium is applied directly to the surface of a running material web, which is supported on a surrounding counter surface in the area of the application point.
  • Such a circumferential counter surface is formed by the outer surface of a rotating counter roller, the surface of a circumferential endless belt or the like.
  • the liquid or pasty medium is first applied directly to the surface of a circumferential application area.
  • Such a circumferential application surface is designed as a circumferential surface of a rotating application roller, as a surface of a circumferential application endless belt or the like.
  • the applied medium is transferred from the surface of the circumferential application surface, that is to say, for example, from the outer surface of an application roller, to the surface of a material web in an application gap.
  • Such an application nip is thus between an application roller and a counter roller or For example, it is also formed between a continuous feed belt and a counter-endless belt and the material web is passed through the application gap in order to transfer the medium there to the material web.
  • the cross profile over the material web width is influenced in a zone-controlled manner during the application directly onto the material web or during the application initially onto an application area.
  • This influencing takes place by a zone-wise different metering of the application quantity directly at the application device, that is to say, for example in the case of a free jet nozzle application unit, by zone-wise different setting of the nozzle gap.
  • the method according to the invention can be used for different types of orders. So e.g. for application of the medium in a free jet, for application of the medium by means of a doctor element, for application of the medium by means of a scoop roller and comparable types of application. In a preferred embodiment, however, the application takes place in a free jet.
  • the medium previously applied is controlled in order to adjust the line weight longitudinal profile.
  • the medium previously applied and applied in the cross profile is thus removed as a whole, if necessary, for example by means of a doctor element in order to regulate the desired final coat weight.
  • a squeegee blade, squeegee bar or roller squeegee is used as the squeegee element.
  • a Air knife or another leveling element known to those skilled in the art can be used.
  • control of the cross profile and the control of the longitudinal profile of the medium applied are carried out separately from one another in automatic control loops.
  • the control loops are based on measurements of the profile of the medium which has been applied to the surface of the material web or to the surface of the application surface, i.e. the measurements are placed downstream of the point at which the longitudinal profile is influenced or, alternatively, the measurements can be placed directly downstream of the job site.
  • the measured actual values of the profile applied are continuously compared with the computer using predetermined target values for the profile and the resulting deviations are converted into corresponding separate control instructions for influencing the cross profile and for influencing the longitudinal profile.
  • the second method according to the invention works analogously to the previously described first method according to the invention, however, a total metering of the application quantity is now carried out on the application device in order to influence the longitudinal profile directly during the application, and in a downstream arrangement there is a zone-wise influencing of the applied medium by means of a leveling element, to influence the cross profile of the medium.

  • Such adjusting devices or adjustable dosing devices are known per se and are explained, for example, in DE 44 32 177 A1 mentioned at the beginning.
  • a leveling device is provided downstream of the application device, which in the case of a direct application of the medium is either assigned to the same counter surface to which the application device is assigned or is assigned to a separate counter surface.
