Abstract
A sheet manufacturing apparatus includes a rotatable drum unit that includes an opening unit having a plurality of openings on a surface thereof and a cylindrical unit having no opening; a material supply unit that is provided to supply a material containing fibers to the drum unit by airflow; and a forming unit that forms a sheet by using the material passing through the openings, in which at least one of the drum unit and the material supply unit has a dispersion unit in which airflow is dispersed further on a downstream side than on an upstream side in a supply direction of the airflow.
Claims7
A sheet manufacturing apparatus comprising:
- a rotatable drum unit that includes an opening section having a plurality of openings on a surface thereof and a cylindrical section having no opening;
- a material supply unit that is provided to supply a material containing fibers to the drum unit by airflow;
- and
- a forming unit that forms a sheet by using the material passing through the openings,
- wherein at least one of the drum unit and the material supply unit has a diffusion section in which airflow is diffused further on a downstream side than on an upstream side in a supply direction of the airflow.
A sheet manufacturing apparatus comprising:
- a housing unit that surrounds a periphery of a drum unit;
- and
- a suction unit that sucks air within the housing unit below the drum unit,
- wherein outside air is suctioned from a sliding contact part between the drum unit and the housing unit during suction by the suction unit.
A sheet manufacturing apparatus comprising:
- a rotatable drum unit that is a hollow cylindrical drum unit and includes an opening section having a plurality of openings;
- a supply unit that includes a supply port for supplying a material containing fibers transported by airflow to the drum unit;
- and
- a forming unit that forms a sheet by using the material passing through the openings of the drum unit,
- wherein the supply port is disposed at a predetermined distance with respect to the opening section of the drum unit in a rotation axis direction of the drum unit, and
- wherein a diameter of the supply port is smaller than an internal diameter of the drum unit.
