Problems solved by technology

[0010] However, the scheme shown in this publication cannot suppress the inclined state of the end portion on the coating liquid starting side where the coating liquid is started to be coated on the substrate, and in the above case, the responsiveness of the suction valve, etc. are not sufficient, and the coating The end of the stop side is still in a slightly inclined state, and the coating liquid cannot be applied to the substrate with a certain uniform thickness

Embodiment Construction

[0051] Hereinafter, the intermittent coating method and the intermittent coating apparatus according to the embodiment of the present invention will be described in detail based on the drawings. In addition, the intermittent coating method and intermittent coating apparatus according to the present invention are not limited to the following embodiments, and can be appropriately modified within a range that does not change the gist of the invention.

[0052] Such as Figure 4 As shown, in this embodiment, while the substrate 1 is hung on the support roll 2 and moved, the control device 21 is used to control the conveying device 20 that conveys the coating die 10.

[0053] The front end surface 10a of the coating die 10 is guided downward to a position where the front end surface 10a of the coating die 10 is spaced apart from the substrate 1 moved in the above manner by a desired distance, while making the coating The die head 10 moves in the same direction as the base material 1 al...

Abstract

The technical problems of the present invention reside in that coating liquor can be coated on a substrate web with certain even thickness when the mobile substrate web is coated with coating liquor intermittently from head of a coating model. Coating liquor (12) is coated on the mobile sheet substrate web (1) intermittently from a discharge opening (11) located at front end surface (10a) of the coating model head (10), while coating liquor is coated intermittently on the substrate web, the process as shown below: the coating model head and the substrate web are moved in same direction when the coating model head provides coating liquid to the substrate web; the coating model stopping moving or moving along the direction opposite to the substrate web, coating liquor being coated from the coating model head to the moving substrate web; When coating liquor is stopped providing to the substrate web from the coating model head, the coating model head and the substrate web are moving alongsame direction.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2007-99952. Technical field [0002] The present invention relates to an intermittent coating method for intermittently supplying a coating liquid from a slit-shaped discharge port provided on the front end surface of a coating die to a moving sheet-like substrate and intermittently coating the coating liquid on the substrate, and Intermittent coating device. [0003] In particular, the above-mentioned intermittent coating method and intermittent coating apparatus have the following characteristics: at the end of the coating start side where application of the coating liquid to the substrate is started, and the end of the coating stop side where application of the coating liquid to the substrate is stopped. The surface is formed perpendicular to the substrate without being inclined, and the coating liquid can be coated with a certain uniform thickness on the substrate. Background technique [0004] Co...
