PROBLEM TO BE SOLVED: To provide a coating feeding system which secures the moment flow rate of a coating to inhibit the pulsating and which prevents the sedimentation of a coating. SOLUTION: The coating feeding system 10 is provided with a coating passage 3 and coaters 21, 22. It is also provided with a transfer pump 6 and a buffer 7. The coating passage 3 supplies the coating from a tank 5 and returns the same to the tank 5 therethrough. The coating is supplied to the coaters 21, 22 through a branch 40 connected with the coating passage 3. The transfer pump 6 pumps the coating from the tank 5 and sends out the coating. The buffer 7 stores a constant volume of the coating sent out of the transfer pump 6 and transfers the stored coating to the coating passage 3 under constant pressure. COPYRIGHT: (C)2009,JPO&INPIT
