An apparatus for manufacturing a powder-containing article containing a powder, comprising: a sheet conveyance device which conveys, along a conveyance path, a sheet in which a given region from an obverse surface toward a reverse side thereof is composed of a non-woven fabric; a powder supply device which is provided on the conveyance path, and supplies the powder to at least a partial zone of the sheet, from an obverse side of the sheet; and a fiber-raising device which is provided on the conveyance path at a position upstream, in a conveyance direction of the sheet, of a powder supply position where the powder is supplied to the sheet, and raises fibers in at least part of the powder supply zone of the sheet, from the obverse side of the sheet, wherein the fiber-raising device comprises one or more blades each protruding toward the obverse surface of the sheet to contact the sheet; the sheet conveyance device conveys the sheet such that the sheet is moved relative to the one or more blades, the fiber-raising device comprises a drive section which moves the one or more blades from an upstream side toward a downstream side of the conveyance direction of the sheet, at a movement speed less than a movement speed of the sheet, the drive section rotationally drives the one or more blades along a circumferential plane of a circular cylinder having a center line which is a line extending in a direction orthogonal to the conveyance direction of the sheet and parallel to the obverse surface of the sheet, each of the one or more blades has a first face facing the upstream side of the conveyance direction of the sheet at a contact position with the sheet, and a second face facing the downstream side of the conveyance direction of the sheet at the contact position, the first face has a shape extending in the radial direction of the circular cylinder, the first face has an outer edge in the radial direction of the circular cylinder, and the second face has a shape extending from the outer edge of the first face, toward a downstream side of the movement direction of the one or more blades and an inward side of the radial direction of the circular cylinder. a sheet conveyance device which conveys, along a conveyance path, a sheet in which a given region from an obverse surface toward a reverse side thereof is composed of a non-woven fabric; a powder supply device which is provided on the conveyance path, and supplies the powder to at least a partial zone of the sheet, from an obverse side of the sheet; and a fiber-raising device which is provided on the conveyance path at a position upstream, in a conveyance direction of the sheet, of a powder supply position where the powder is supplied to the sheet, and raises fibers in at least part of the powder supply zone of the sheet, from the obverse side of the sheet, wherein the fiber-raising device comprises one or more blades each protruding toward the obverse surface of the sheet to contact the sheet; the sheet conveyance device conveys the sheet such that the sheet is moved relative to the one or more blades, the fiber-raising device comprises a drive section which moves the one or more blades from an upstream side toward a downstream side of the conveyance direction of the sheet, at a movement speed less than a movement speed of the sheet, the drive section rotationally drives the one or more blades along a circumferential plane of a circular cylinder having a center line which is a line extending in a direction orthogonal to the conveyance direction of the sheet and parallel to the obverse surface of the sheet, each of the one or more blades has a first face facing the upstream side of the conveyance direction of the sheet at a contact position with the sheet, and a second face facing the downstream side of the conveyance direction of the sheet at the contact position, the first face has a shape extending in the radial direction of the circular cylinder, the first face has an outer edge in the radial direction of the circular cylinder, and the second face has a shape extending from the outer edge of the first face, toward a downstream side of the movement direction of the one or more blades and an inward side of the radial direction of the circular cylinder.
