Problems solved by technology

[0006] However, in the inventions disclosed in Patent Document 1 and Patent Document 2, although the gap between the tip lip and the plate can be adjusted, since the adjustment is performed by tightening and tightening the bolts, the bolts usually have It is difficult to adjust to an accurate position due to play, etc., and due to the lack of reproducibility of the adjustment, it is necessary to repeatedly adjust the bolts to be successful occasionally.
In addition, in this adjustment by bolts, there will be many practical problems such as the following: the bolts are loosened during the coating process due to the vibration of the rotating body of the coating device, and the gap changes, resulting in uneven coating. Coating fluid applied; plate breakage

Abstract

Intended is to homogenize stably the clearance between the tip lip of an applying die and a web. Provided is an applying apparatus for applying an application liquid to a moving web from the tip lip of the applying die fixed on a bed. The applying apparatus is characterized in that a plurality of shims fixed on the bed by bolts are arranged in that joint zone of the jointing face of the bed which is to be jointed to the applying die, so that the straightness of the tip lip of the applying die is adjusted by adjusting the individual thicknesses of the shims arranged.

Description

technical field [0001] The present invention relates to a coating device and a coating method, in particular to a coating used to form photosensitive emulsifiers, magnetic fluids, viewing angle-enhancing films, and antireflection films on supports such as plastic films, paper, and metal foils. A coating device and a coating method for a coating liquid such as a solution, a pigment liquid for color filters, a solution for forming a surface protection film, and the like. Background technique [0002] As a method for applying a coating liquid to the surface of a moving support (plate, etc.), a die coating method is known. In recent years, along with the high performance of the film formed by the die coating method, etc., a technology for forming a high-precision laminated film in a thinner lubricating film thickness of 20 [μm] or less has been demanded. In order to uniformly form such a thin film, the accuracy of the coating device, particularly the gap between the front end l...
