Patent ID: 7105203

Claim:
An intermittent coating apparatus, comprising: a nozzle, which applies a coating to a base material; and intermittent coating supply means, which intermittently feeds the coating to the nozzle, stops the feeding of the coating to the nozzle, and discharges remaining coating to a return side, the intermittent coating supply means including: a coating tank, a flow path supplying coating from the coating tank, the flow path including a feeding side in communication with the nozzle, a return side in communication with the coating tank, a segment that connects the feeding side and the return side, and a feedline that connects the segment and the coating tank, a feeding side two-way valve, positioned between the flow path segment and the feeding side of the flow path, that intermittently feeds and stops the feed of the coating to the nozzle, a return side two-way valve, positioned between the flow path segment and the return side of the flow path, that intermittently discharges remaining coating to the tank through the return side of the flow path, and stops discharge of the remaining coating to the tank through the return side of the flow path, and control means causing both the feeding side two-way valve and the return side two-way valve to open and discharge coating before the time that coating of the base material with the coating is started, and thereafter, causing the return side valve to close after expiration of a prescribed period of time to stop further discharge of the coating to the return side, wherein the feedline connects with the segment between the feeding side two-way valve and the return side two-way valve.
