INTERMITTENT COATING DEVICE
Document Type and Number:
Japanese Patent JP2022034986
Kind Code:
A
Abstract:
To provide an intermittent coating device that suppresses fluctuations in liquid pressure of a coating liquid to make the coating thickness in the coating section uniform when intermittently coating the web.SOLUTION: In an intermittent coating device 1 having an intermittent valve 10 that intermittently delivers a coating liquid to a die 14, a liquid pressure adjusting pipe 56 branched from a liquid pipe that delivers the coating liquid pumped from the pump 30 to the intermittent valve 10 is vertically provided. An upper end of the liquid pressure adjusting pipe 56 is closed, and connected with an air pipe 74 to which air is delivered. A partition member 64 is provided to partition a first space 80 storing the air delivered into the liquid pressure adjusting pipe 56 and a second space 82 including a liquid surface of the coating liquid. The partition member 64 moves upward as a pressure of the air from the air pipe 74 decreases to lower an internal pressure of the second space 82 so as to lower a liquid pressure value P.SELECTED DRAWING: Figure 2
