PURPOSE: To effectively attach baby powder on a continuous laminated sheet for producing a disposable diaper by forming an air flow having a velocity gradient on the surface of the sheet by running the sheet at high speed, and by feeding the baby powder to the air flow. CONSTITUTION: A continuously laminated sheet 2, which becomes each disposable diaper when being cut, is run at high speed in the longitudinal direction. Thereby, an air flow from 28 to 30 having a velocity gradient with the higher velocity at the position nearer to the surface 6 of the sheet 2 is generated on the surface 6 of the sheet 2. Baby powder 13 is fed to the air flow. The baby powder is sucked and attached to the surface 6 of the sheet 2 by the phenomenon of the pressure being lowered according to the approach to the surface. |
