PURPOSE: To prevent thickness of a coating at a coating starting end from becoming larger, in a device for intermittently applying a coating material to a base material which is continuously running by making straight a coating starting end and a coating terminal end which are formed intermittently on the base material. CONSTITUTION: A base material 12 is caused to continuously run by a roll 13, while a coating material 11 fed to a nozzle 1 is intermittently applied onto the material 12 from a head 2. The head 2 shuts off the flow of the material 11 to the nozzle 1 when the material 11 is not applied, thereby to lead the material 11 to other unit than the nozzle 1 and at the same time, the head 2 draws the material 51 in the nozzle 1 and at the outlet of a slit 7 into a suction part formed in the nozzle 1, so that when coating of the material 11 is restarted, flow of the material 11 is released to the nozzle 1 and at the same time the material 11 having been drawn into the suction part is returned into the nozzle 1. |
