Description

  • The invention relates to an application unit of a coating or sizing device for applying treatment substance on a fiber web, which application unit comprises a support beam and an application module. More especially the invention relates to an application unit according to the preamble of claim 1.
  • As known from the prior art in fiber web producing processes typically comprise an assembly formed by a number of apparatuses arranged consecutively in the process line. 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. In this description and the following claims by fiber webs are meant for example paper and board webs.
  • In production of fiber webs, for example of paper or board webs, treatment substances are added 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. In coating onto surface of a fiber web, is added a layer or layers of coating paste (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. 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. In some types of coaters and sizers, for example film transfer coaters, 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. Typically 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 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 application module comprises several hundred, for example 750 feed openings at 50 - 150 mm distance. The application module is typically constructed of acid proof steel and as one piece to avoid leakage points. The acid proof steel construction for the application module is heavy and thus difficult to be moved and complicated and expensive to produce. In some cases even acid proof steel is not resistant enough for the chemicals used in the treatment substance.
  • In DE utility model publication 202004021048 is disclosed a device for applying a fluid substance on a passing material web comprising an application device for applying the substance and/or a doctor for smoothening and/or dosing the substance. The application and/or the doctor are supported by a support frame, which can be produced of steel, refined steel, synthetic material of fiber reinforced material.
  • In EP patent application publication 1211053 is disclosed a carrier beam, which has a longitudinal and hollow body with a round or polygonal cross section of a fiber compound material produced by winding. The fiber compound material can be plastics reinforced with glass or carbon fibers. The beam can be used in a web coating machine, using a liquid or paste coating medium to be applied to the surface of a moving web of paper or cardboard, for supporting at least one applicator and/or doctor.
  • In cases where support structures, for example the support beams, for treatment substance application devices, especially for application modules, are of fiber compound material or of other composite material and the application device is of metallic material thermal expansion in longitudinal direction i.e. in cross direction of the fiber web may cause problems due to dissimilar bending behavior of the structures caused by different thermal expansion coefficients of used materials.
  • When a composite structure is produced by winding, the production method sets limits to the design of the structure.
  • An object of the invention is to create a method and an application unit of 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.
  • Another object of the invention is to provide an application unit, which is producible cost-effectively.
  • In order to achieve the above objects the application unit of a coating or sizing device for applying treatment substance on a fiber web according to the invention is mainly characterized by the features of claim 1.
  • According to the invention the application unit of a coating or sizing device for applying treatment substance on a fiber web, which application unit comprises a support beam and an application module comprising at one of its longitudinal ends an opening for the treatment substance inlet, a feed chamber with feed openings located spaced apart in longitudinal direction of the application module and a flow-through at the other longitudinal end of the application module, which application module is supported on the support beam and which application module of the application unit is constructed at least partially of composite material.
  • According to an advantageous feature the support beam of the application unit is constructed at least partially of composite material.
  • According to an advantageous feature the application module of the application unit is constructed substantially totally of composite material.

  • The connecting element between the application module and the dosing arrangement at the application module's side can also be a separate connecting element attached to the application module. Depending on the application type the dosing arrangement can comprise a connecting element and the dosing element or the dosing element can be connected directly to the application module.
  • The 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 extends over the whole width of the fiber web and can be over 10 meters long. The treatment substance is fed to the application module of the application unit at one of its longitudinal ends and applied from a feed chamber 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 application module comprises several hundred, for example 750 feed openings at 50 - 150 mm distance.
  • If the application unit is constructed to have the connecting element and/or the attachment element and/or support beam as separate parts of the application module, the application module is advantageously produced by pultrusion or winding. In these types of case the application module is constructed of composite material and the elements to be attached can be of same or different composite material or of other material, for example steel.

The application module 10 is supported by an attachment element 12 on the support beam 13 of the application unit.
  • In this example the connecting element (the formfitting attachment) 14 at the application module's side between the application module 10 and the dosing arrangement (the rod-bed 15 and the rod 16) are formed as part of the application module 10. The connecting element between the application module 10 and the dosing arrangement 15, 16 at the application module's side can also be a separate connecting element attached to the application module 10. Depending on the application type the dosing arrangement can comprise a connecting element and the dosing element as in this example or the dosing element can be connected directly to the application module 10 by the connecting element 14. The attachment element 12 can also be formed as part of the application module 10.
