Abstract
To provide a sheet former capable of suitably regulating the thickness of a sheet forming body in a width direction in response to factors changing with time. A sheet former includes at least one vessel which stores slurry as a raw material, a wire cylinder immersed in the slurry inside the vessel and making sheets from solid components in the slurry while being rotated, and a sheet-forming amount regulator which regulates an amount of the solid components for making sheets by the wire cylinder in a width direction in accordance with a thickness of a sheet forming body in the approximately width direction formed for making sheets by the wire cylinder.
Claims6
A sheet former comprising:
- at least one vessel which stores slurry as a raw material;
- a wire cylinder immersed in the slurry inside the vessel and making sheets from solid components in the slurry while being rotated;
- and
- a sheet-forming amount regulator which regulates an amount of the solid components for making sheets by the wire cylinder in a width direction and in accordance with a thickness of a sheet forming body, in the substantially width direction when the sheets are made by the wire cylinder,
- wherein the sheet-forming amount regulator includes a sheet-shaped regulator covering at least part of the surface of the wire cylinder in a circumferential direction by sheet pieces divided into plural pieces in a width direction of the wire cylinder, which regulates the amount of solid components by covering the surface of the wire cylinder by each divided sheet piece.
