Definitions

  • the present invention relates to a curtain coater, and more particularly, to an edge guide for a curtain coater.
  • Coated paper such as printing paper used for printing brochure or catalog, carbonless duplicating paper and thermal recording paper is manufactured by coating a coating material on a web (base material), that is, base paper, by a coater, and then by drying the coated web.
  • the machine for coating a coating material is called a coater.
  • coaters such as a blade coater, a rod coater and an air knife coater that adopt the post-metering method predominated as mainstream of coaters.
  • an excessive amount of coating material is firstly coated on a web, then an excessively coated coating material is scratched off by a blade or a rod of small diameter, or is blown off by an air knife, and metering is performed.
  • curtain coaters in which a curtain film of a coating material is spouted onto a running web from a die (a chamber with nozzle that forms a curtain film of coating material) to coat the web with the coating material, have been widely used.
  • curtain coaters have long been used in the field of photographic printing paper or the like, they were not used in the paper manufacturing industry. This is because coating by using the curtain coaters was not stable due to engulfing of air at a high speed of 1000m/min or greater, bubbles got mixed into coating material, unstableness of the curtain film caused by an insufficient mechanical accuracy, etc.
  • the curtain coating machine is advantageous in that it is easy in maintenance because it does not have consumable components such as blades and rods, it can adjust the amount of coating easily with a high accuracy, it is user friendly with good operability, it is highly effective in improving surface properties because it employs contour coating, and so on.
  • a curtain film of coating material falls by its own weight when it is separated from a die. At that moment, edges are pulled inward by a surface tension of the coating material, resulting in neck-in in which width of the curtain film becomes narrower. When the neck-in occurs, the both end portions of the curtain film becomes thicker. If the curtain film with the end portions thereof being thickened is coated on a web as it is, corresponding web portions will be thickly coated, resulting in insufficient desiccation for that portions, which will cause a so-called blocking phenomenon in which paper sticks to each other when it is rolled up.
  • the width of a curtain film is made greater than that of a web, and portions of the curtain film that protrude beyond the web are received by edge pans provided below the web so that the coating material is reused as a cyclic usage.
  • coating materials are likely to be mixed with each other. Therefore, such a conventional coating method cannot be employed. Instead, coated-up coating must be performed in which, the width of a curtain film being made smaller than that of a web, all of the coating material of the curtain film is coated on the web, and non-coated portions (dry edges) are left to be present in both end portions of the web. Therefore, in order to prevent such a neck-in, an edge guide is provided.
  • FIG 8 is a conceptual diagram of such an edge guide.
  • A represents a die
  • B represents an edge guide
  • c represents a curtain film of coating material
  • w represents a web.
  • the edge guide B is made of metal such as stainless steel to prevent the neck-in.
  • flow speed v of the curtain film c of the coating material is slow in the neighborhood of the edge guide 2 as shown in Figure 8 , and is uniform in areas other than in the neighborhood of the edge guide B. If the flow rate of the curtain film c of the coating material is small in the above situation, the curtain film c flows away from the edge guide B, resulting in the occurrence of the neck-in.

  • the edge guide main body C when shown in a plane cross-sectional view, is shaped as a mountain with the guide surface a being a peak thereof.
  • a bottom face of the edge guide main body A is an inclined face, a front end thereof (inner side in a web width direction) being positioned in the lowest and getting higher toward an rear end thereof (outer side in the web width direction).
  • the metal separation sheet f is attached to the bottom face.
