Definitions

  • the invention relates to a method for coating a blade.
  • Blades are used today for a variety of uses. For example, it is known to use blades in paper machines. Here, the blade is placed and contacted immediately adjacent to a moving surface, in particular a rotating roller or drum, for example, to remove water from the surface of a roller, to set a coating thickness, to remove an excess of coating To keep the surface of a roll of foreign matter or to detach a layer or a fabric or the like from a roll or drum.
  • a moving surface in particular a rotating roller or drum
  • a coating thickness to remove an excess of coating
  • Such blades are used in the form of doctor blades, doctor blades or scrapers at various locations, e.g. in the forming, pressing or drying section as well as in calenders.
  • the blades are in direct contact with a moving surface, such as a roller surface, in a paper machine, for example, the blades are subject to high wear over time. Depending on the purpose, the durability or life of a blade can be a few hours to several months.
  • a coating of the blade material is expedient.
  • Known coating methods for example, lead a strip-shaped body linearly past an application nozzle with which a corresponding coating material is applied. Disadvantage of such known methods, however, is in particular the irregular thickness of the applied coating. This leads to various problems when using a blade coated in this way: for example, the blade which is in direct contact with the roll surface can no longer guarantee a uniform cleaning of a surface, the service life is shortened, since the fluctuating coating thickness has a disadvantageous effect on the properties of the blade material.
  • Quality loss of the product produced is also to be feared.
  • an uneven coating can adversely affect the blade holder, which may not ensure a secure grip. A possible spalling of the coating is thereby more likely.
  • the present invention is therefore based on the object of specifying a method for coating a blade, which reduces the disadvantages described, with a uniform coating to be obtained in a simple manner without high effort in a rational manner.
  • the object of the invention is achieved by a method for coating a blade according to claim 1, wherein the blade has a blade body with a blade top and a blade bottom, with the steps of the spiral Winding the blade body to be coated on a cylindrical base body with the blade side to be coated to the outside, coating a blade side of the wound blade body with a coating material, after curing of the coating material performing a cut through the coating, which is placed under a slope which the slope of the on the cylindrical base body spirally wound blade body corresponds, and unwinding of the coated blade of the cylindrical base body.
