散布されなくなる。Reduced pressure acts intermittently on the continuous powder flow 12 falling through the chute 7, and the direction of the flow changes intermittently. That is, as shown in FIG. 3, when the suction opening 19 of the rotating vacuum roll 6 is not facing the suction nozzle 23, the reduced pressure inside the rotating vacuum roll 6 acts on the continuous powder flow 12. As a result, the powder is scattered onto the moving porous web 8, and as shown in FIGS. 2 and 3, the suction opening 19 faces the suction nozzle 23. When the rotating vacuum roll 6 is under pressure, the continuous powder flow 12 is affected by
It is sucked into the vacuum roll 6 and is no longer spread onto the porous web 8.

ｉｎ程度での間欠散布が可能である。Therefore, by rotating the depressurized rotary vacuum roll 6 at a predetermined rotation speed, powder and granules are intermittently spread onto the moving porous web in a predetermined spread width and a predetermined number of fabric lengths in a predetermined intermittent spreading cycle. It becomes possible to disperse the During spreading in the direction perpendicular to the moving direction of the porous web 8, the width of the chute 7 determines the spreading length, and the spreading length in the moving direction of the porous web 8 is determined by the rotational speed of the rotary vacuum roll 6, the suction opening 19 It is determined by the width of the porous web 8, the falling speed of the powder and the moving speed of the porous web 8. In addition, in this embodiment, the intermittent spraying cycle (times/5 inches) and the rotational speed (rpm) of the rotary vacuum roll 6 are the same, and the width of the suction opening 19 is set to 115 to 1/4 (1/4) of the circumference.
When the opening angle is set to about 70 to 90 degrees) and the vacuum air speed is set to 30 to 40 s/sin, the moving speed of the porous web 8 is 100" to 120 m.

板２２により、十分な風速まで増幅されている。When the moving speed of the porous web 8 is low, the intermittently sprinkled powder and granules will move onto the porous web 8 from the time they fall onto the porous web 8, even without such fixing.
However, if such fixing is not performed when the moving speed is high, the moment the dispersed powder falls onto the porous web 8, the moving speed of the porous web 8 and the powder particles The air is scattered from the porous web 8 depending on the speed relative to the falling speed of the body, and falls again between each intermittent spraying portion, making the intermittent spraying pattern unclear. The wind speed is amplified to a sufficient level by the air intake 21 for fixing the spread powder and granular material in the chute 7 and the partition plate 22 for amplifying the air for fixing the spread powder.
