Definitions

  • the invention relates to a coating or sizing device for applying treatment substance on a fiber web, which device comprises an application unit with an application module for applying the treatment substance onto the fiber web or onto a roll for transferring the treatment substance onto the fiber web. More especially the invention relates to an application unit according to the preamble of claim 1.
  • a typical production and treatment line comprises a head box, a wire section and a press section as well as a subsequent drying section and a reel-up.
  • the production and treatment line can further comprise other devices and sections for finishing the fiber web, for example, a sizer, a calender, a coating section.
  • the production and treatment line also comprises at least one winder for forming customer rolls as well as a roll packaging apparatus.
  • fiber webs are meant for example paper and board webs.
  • treatment substances are added onto the fiber web directly or by first applying the treatment substance onto a surface of a roll that then transfers the treatment substance onto the fiber web.
  • Sizing is used to alter the properties of a fiber web by adding sizing agents (sizing medium), for example glue chemicals onto the surface of the fiber web at the fiber web machine.
  • sizing medium for example glue chemicals onto the surface of the fiber web at the fiber web machine.
  • coating onto surface of a fiber web is added a layer or layers of coating color (coating medium) at a coating station followed by drying.
  • the coating or the sizing of a fiber web typically utilizes a coating device - a coater - or a sizing device - a sizer.
  • a coating device - a coater - or a sizing device - a sizer In connection with the coaters and sizers different kinds of application technology for application of the coating medium or the sizing medium on the fiber web are employed, for example curtain technology or blade coating technology or film transfer technology or rod coating technology or air brush coating technology or spray coating technology.
  • an application module of an application unit is utilized for applying the treatment substance on to a coating roll for then transferring it onto the fiber web of for applying the treatment substance directly onto the fiber web.
  • the application unit and the application module supported on a support beam of the application unit extend over the whole width of the fiber web and can thus be even over 10 meters long.
  • the application module is slender and its own stiffness is not enough to provide the required loading force for the application element, such as a doctor blade or a rod, and therefore the required stiffness is provided by the stiff support beam or element.
  • the treatment substance is fed to the application module at one of its longitudinal ends and applied through feed openings located spaced apart in longitudinal direction of the application module and at the other longitudinal end is provided a flow-through.
  • the treatment substance is applied onto the surface of the roll, for example the sizing or the coating roll, just before the application element, for example the doctoring blade or the rod.
  • the space before the blade or the rod is delimited by a dam blade or by an over-flow edge to create a space filled with the treatment substance in order to ensure that no areas without the treatment substance exists.
  • the application module In order to provide even and desired treatment substance application one important requirement of the application module is straightness, which is accomplished by straightness of the support element of composite material or of steel structure with a cooling liquid space for uniform temperature or with pneumatic devices or the steel structure may be without cooling liquid and/or temperature isolated and/or sheathed. Independent of the material of the support element deflection of the support element due to application forces of the application element causes geometric error and undesired variation of application force in cross direction of the application i.e. in cross direction of the fiber web. In order to minimize the geometric error very stiff support beams with large cross section and very strict operational temperature adjustment have been required.
  • the application element i.e. the blade or the rod is attached to a holder, for example to a rod-bed.
  • the holder with accompanying support and fastening means is in turn attached to a beam or corresponding support structure arranged on the frame of the machine.
  • the beam or corresponding support structure of a coating / sizing rod/blade is arranged movable by loading means arranged at each end of the beam or corresponding support structure by which the main loading of the blade or rod is provided.
  • the loading of the blade or rod is typically arranged by profiling loading means for example by spindles that load cross-directional means for example a loading hose (a hose-loaded blade) and/or by a rigid loading plate, which spindles are spaced apart at certain, typically short intervals at the cross direction of the fiber web to be coated or sized.
  • load cross-directional means for example a loading hose (a hose-loaded blade) and/or by a rigid loading plate, which spindles are spaced apart at certain, typically short intervals at the cross direction of the fiber web to be coated or sized.
  • the contact force of the blade or rod on the opposing surface is increased by means of loading hoses acting on the blade or rod holder.
  • Loading hoses normally have an oval cross-section.
  • the loading hose is set between the holder and its support.
  • a couple of millimeters deflection of the application module may create a 10% change in loading of the loading hose, which will cause visible changes in treatment application on the fiber web when grooved application rod is used and in cases a smooth surfaced application rod is used even smaller deflections will cause visible changes in application of the treatment substance.
  • Furthermore when there are changes in loading may cause problems in the function of the dam blade or the over-flow edge since the lubrication conditions of the blade/edge may decrease and air may enter to the space before the application element.
  • An object of the invention is to create a coating or sizing device for applying treatment substance on a fiber web, in which the above problems and disadvantages are eliminated or at least minimized.
  • An object of the invention is to create a coating or sizing device in which the problems relating to the deflection of the application module and/or of the support element of the application module of the coating or sizing device are eliminated or at least minimized.

  • the articulated fixing point of the application module is positioned advantageously such that perpendicular displacement in respect of the tangent executes the equation: angular change of the application module ⁇ 0,5 ° / 1 mm.
  • the floating mounting located between the application module and the support element compensates and corrects the deflection of the application module and/or the support element and keeps the application element perpendicularly against the roll.

  • the adjustment cylinders form a closed system, in which each cylinder has the same support force.
  • the corresponding adjustment cylinder/-s adapts new position maintaining the constant support force in relation to the application module.
  • the adjustment system provides that the application element load against the roll is constant in cross direction of the fiber web i.e. in longitudinal direction of the roll.
  • the requirements of the support element of the application module can be reduced and simultaneously a very constant force of the application element is reached.
  • the adjustment cylinders are replaced by adjustment screws that are manually or automatically operated. This requires good conditioning of the operating environment.
