SHEET PRODUCTION DEVICE

Discharge of fiber and other particulate to the outside of a housing unit is prevented. A drum unit in which material including at least fiber passes through apertures; a conveyance unit configured to deposit the airborne material that passed the drum unit as a web and convey the web; a housing unit configured to cover the drum unit， contact the web on the downstream side in the conveyance direction of the web， and contact the conveyance unit on the upstream side in the conveyance direction of the web from the downstream contact position; and a forming unit that forms a sheet using the web.

防止纤维及其他颗粒物向壳体单元（housing unit）外部逸散的装置包含以下组件：鼓单元（drum unit），至少包含纤维的物料可通过其上的开孔（apertures）；输送单元（conveyance unit），被配置为将经过鼓单元的气载物料沉积为纤维网（web）并输送该纤维网；壳体单元（housing unit），被配置为覆盖鼓单元，在纤维网输送方向的下游侧与该纤维网接触，且从该下游接触位置起，在纤维网输送方向的上游侧与输送单元相接触；以及成型单元（forming unit），利用该纤维网成型纸页（sheet）。
