Definitions

  • the present invention relates to a device for direct or indirect application a liquid or pasty coating medium on a running material web, in particular made of paper or cardboard, according to the preamble of claim 1.
  • a running web of material for example made of paper, cardboard or a Textile material consists of one or both sides with one or more layers of Coating medium, for example paint, starch, impregnating liquid or the like, to provide.
  • Coating medium for example paint, starch, impregnating liquid or the like.
  • the coating medium can also be acidic or others have aggressive properties.
  • a generic device for the direct or indirect application of a liquid or pasty coating medium on a running web of material, in particular Paper or Cardboard, is known from DE 44 32 179 C1 of the applicant and includes one with the Elastic medium in direct contact with an elongated functional unit, namely a free jet nozzle applicator with a feed gap intended for the coating medium, the between a front wall arranged on the inlet side and an outlet side arranged rear wall is formed, and with feed channels through which the liquid Medium is fed from a central distribution pipe into the feed gap, as well as a the functional unit carrying elongated support element, namely one with the Functional unit integrally connected support beam, which is also the central distribution pipe includes.
  • construction methods are also common, for example, in which the functional unit and the support element as separate parts from the same Made of materials and fixed to each other by means of a welded joint.
  • the Functional unit and the support element usually have a length of several Meters.
  • liquid or pasty Coating medium is known to be applied directly to the surface of the running material web, that during the order on a rotating counter surface, for example an endless belt or a counter roller.
  • the liquid or pasty coating medium is initially on a support surface, e.g. the surface of a counter roller designed as an application roller, applied to from there in a nip through which the web of material passes through to be transferred from the applicator roller to the material web.
  • the coating medium pumped by the device is usually due to the Flow through various device components and the passage of circulating devices or by the action of specially provided heating devices or drying devices connected downstream from the functional unit heated. Due to the significant temperature difference between the warm Coating medium or the partial areas of the functional unit heated by the coating medium and the colder support element and the resulting different Changes in the length of these components create a kind of "bimetal effect" that a warping or bending of the device structure with respect to the one to be coated Surface and thus, unless suitable countermeasures are taken lead to considerable inaccuracies in the order to be produced.
  • thermal, mechanical, pneumatic or hydraulic deflection compensation systems also as “ADS” or “Anti Deflection System” known
  • ADS Anti Deflection System
  • One equipped with a thermal deflection compensation system Support element arrangement in which the support element provided with several chambers is flowed through by a bath liquid, z. Described in U.S. Patent No. 3,134,126. By introducing the appropriate temperature control a minimal deflection of the doctor bar is achieved.
  • the functional unit (or essential parts thereof) and the supporting element are firmly connected to one another, this requires in particular one on the connection technology of these two device components coordinated material pairing, i.e. usually the use same materials, so that the designer mostly with regard to the choice of materials is very limited. Material pairings, which are more favorable to the previously explained negative deflection behavior would affect, or the use of special materials for device areas particularly stressed by the coating medium are therefore generally not feasible with the known technologies.
  • the support element and essential parts of the related Functional unit can be processed together, which is large and complex machine equipment presupposes. Finally, is for a particular functional unit always produce a special support element that is precisely adapted to it. this leads to at a higher manufacturing and cost expenditure.
  • the invention has for its object a simple and effective generic device to create, which the state of the Disadvantages inherent in technology, in particular a deflection as a result different changes in length of the elongated functional unit and the elongated support element ("bimetal effect) avoids the simplest possible way, easily to different coating conditions is customizable and high quality order results achieved.
  • This task is accomplished by the device solved with the features of claim 1.
  • the webs according to the invention enable the desired thermal shielding of the functional unit and the support element up to today. Furthermore, the webs allow mechanically simple and thus cost-effective way of compensating thermal relative Changes in length between the functional unit and the support element. The webs can with respect to the Torque transfer and heat conduction optimized become.

  • the functional unit can of course be diverse Assemble assemblies or individual parts in order to replace or replace them if necessary Maintenance of these components, especially those subject to high wear Parts to ensure.
  • one serves as an elongated support element Hollow body designed support beam that has a suitable base or surface for attachment of the respective functional unit.
  • the inventors of the present subject matter have recognized that by a physical separation of the parts of the functional unit contacting the coating medium from the support element as well as the provision of the thermal shield between these components, which are connected to one another via a "linear expansion compensation device" formed by the webs are connected, which occur in conventional devices adverse deflection in a simple and effective manner and Way can be effectively minimized or even completely avoided. This the combination of thermal shielding with the Linear expansion compensation still improved.
  • the thermal shield prevents heat transfer from the functional unit to the support element and thus through differently tempered support element areas conditional deformation of the support element itself, while the "linear expansion compensation device" the functional unit and the support element firmly connected with each other, but at the same time an unhindered linear expansion of these two components in the longitudinal direction relative to each other, so that a change in length of the functional unit caused by the heated coating medium not transferred to the support element (or vice versa) and a deformation or cause deflection of the device structure. That’s actually it possible that several functional units are arranged on the same support element can. In known constructions, each functional element had to have its own Support element can be assigned.
