A method for feeding a granular powder from a granular powder feeding hopper onto an upper surface of a sheet material, the method comprising: disposing a feeding passage extending downward from an outlet of the granular powder feeding hopper so that the lower end of the feeding passage faces the upper surface of the sheet material moving beneath the feeding passage; opening and closing the feeding passage with an open-close member to discharge part of the granular powder flowing in the feeding passage to the outside of the feeding passage when the said granular powder is blocked by the open-close member; and thereby intermittently feeding the granular powder from the granular powder feeding hopper onto the sheet material. n
