Powder supply method, method for manufacturing powder containment article using the same, powder supply device, and device for making powder containment article using the same
A powder supply method of supplying a powder to a sheet that is transported along a transport path, the powder supply method implements: a distribution step of dropping the powder from a storage section that stores in the same the powder, to distribute the powder on a surface of the sheet through a distribution port； a first closing stage to move a first opening-closing device such that the first opening-closing device periodically overlaps the distribution port when viewed vertically from above the distribution port, to periodically close the distribution port by the first opening-closing device； a second closing stage to move a second opening-closing device so that the second opening-closing device overlaps the distribution port when viewed vertically from above the distribution port, in the same cycle period as that of the first opening-closing device and at a later time than that of the first opening-closing device, to periodically close the distribution port by means of the second opening-closing device, and moving the second opening-closing device so that the second opening-closing device extends from an upstream side edge of the first opening-closing device which is located on an upstream side of a direction of movement of the first opening-closing device towards the upstream side of the direction of movement of the first opening-closing device, for a period of time during which the edge of the waters arrives the first opening-closing device overlaps the distribution port, when viewed vertically from above the distribution port； and a timing setting step for establishing a difference between a timing in which the second open-close device overlaps the distribution port when viewed vertically from above the distribution port, and a timing in which the first device Open-close overlaps the distribution port when viewed vertically from above the distribution port.Un método de suministro de polvo para suministrar un polvo a una hoja que es trasportada a lo largo de
