  • the waste paper will first pretreated and then dissolved with water added to the substance center. Water is added to the pulp in the pulper. It will thus be pumpable Brought condition. After disassembling the contained in the fiber suspension Bundles of fibers in individual fibers, cleaning and additions to improve strength the various fiber materials and auxiliary materials are mixed.
  • the highly diluted fiber mixture is spread evenly across the width of the Machine distributed. This mixture runs through one on the Fourdrinier machine Slit on the flat, constantly rotating sieve on which the fibers are deposited and the water runs through or is sucked down. This forms the leaf.
  • the paper web still contains 80% Water that is further dewatered by mechanical pressure in the press section.

  • This roll coating can also be produced by casting, whereby a centrifugal casting with special conditions is used, the inorganic Substance is fed simultaneously to the surface of the melt.
  • the object of the present invention is to provide a method for coating a To provide roller body, which is an easy to apply and durable coating delivers that has a good surface quality.
  • the object is achieved in that the coating material in the still flowable state by means of a removal tool at least in the intended one Longitudinal working area of the roller body is subtracted to a predetermined layer thickness becomes.
  • the proposed method results in a uniform coating with simple and also ensures continuous coating process. They are just few procedural steps necessary.
  • the coating is homogeneous in terms of large and small dimensions. This guarantees a low liability of too processing or processing material on the surface of the roller body and so on very good operating behavior and good quality of the end product.
  • This smooth surface offers a particular advantage when used in a frame papermaking, because in this way it is avoided that loose paper substance on a wire guide roller or dryer wire guide roller for pressing out Liquid sticks in papermaking, and paper piles into the pressed Paper.
  • the roller body that is coated largely corresponds to a roller cylinder surface, with which the roller hits the material to be processed. This surface is provided with a layer that is smooth on the one hand, so little Material sticks to you. Secondly, it is stable and forms for the roller in the Rule made of an iron alloy is a corrosion protection.
  • the coating material is first applied to the roller surface in the liquid state applied. In this way, unevenness can be easily compensated and achieve a good bond between the surface and the coating.
  • the coating material can be divided into one under normal processing conditions bring flowable, liquid state and remains liquid until it through the Pulling tool is pulled off.
  • Flowable means a thin to viscous viscous Fluid, which thus adheres to the surface of the fluid already in the fluid state Has roller body.
  • Peeling can be a wiping with a simultaneous smoothing.
  • the pulling tool can protrude into the surface and by a circumferential relative movement between the removal tool and the surface of the coating take / pull off the (all) top layer.
  • This peeling is done in such a way that a predetermined layer thickness is reached.

  • the type and number of air pockets is determined in particular by the composition, the viscosity as well as the application and removal temperature of the coating material certainly. With this in mind, there is a special adjustment the layer thickness in particular to the above parameters, so that an optimal Quality of the coating given with regard to inclusions of the type mentioned is.
  • An indifferent behavior of the material to be processed or the processing process means that only the desired ones are processed with the roller Processing processes run and no negative change in the material surface due to poor surface quality of the roller or Affected by material to be processed. Editing refers to this Case in particular to squeezing liquid out of a paper pulper, but it can also be, for example, an application of color to a paper or a Pressing a material means.
  • the deduction therefore consists on the one hand of removing a certain proportion of the liquid material film, which has a certain toughness or sufficient Viscosity must be sufficient, on the one hand, to adhere to the roll surface stick and on the other hand to be sufficiently mobile that it can be removed by pulling it off partially taken away and mixed so that it is trapped by air is essentially exempt.
