ABSTRACT:
An intermittently laying method for intermittently forming laid layers (14) comprising a fluidized substance (13) laid thereon on a surface of a sheet-like member (12) moving in one direction, in the moving direction, the method comprising steps of: folding a part of the sheet-like member (12) corresponding to a non-laid portion (15) between adjacent laid portions inwardly towards a back surface side of the sheet-like member (12) on an upstream side of a coating head (16) for laying the fluidized substance (13) on the sheet-like member (12) thereby forming a continuous surface-to-be-laid (30) on a surface side; continuously supplying the fluidized substance (13) from the laying means to the surface-to-be-laid thereby forming the laid layer (14); bringing back the inwardly folded non-laid portion (15) so as to be flush with the surface-to-be-laid (30) on a downstream side of the coating head (16); and intermittently interposing the non-laid portion (15) between continuously laid adjacent laid layers (14).
