Abstract
Official abstract text for this publication.
The sheet manufacturing apparatus includes a defibrating unit configured to defibrate a defibration object in the air, and a sheet forming unit configured to form a sheet by using at least a part of defibrated material that has been defibrated by the defibrating unit. The flow path configured to transfer the defibration object to the defibrating unit has a pipeline unit through which the defibration object passes, an opening having a size through which the defibration object does not pass on a surface of the pipeline unit, and an enclosure unit enclosing the pipeline unit such that the opening is positioned inside.
First claim
Opening claim text (preview).
What is claimed is: 1. A sheet manufacturing apparatus, comprising: a defibrating unit configured to defibrate a defibration object in the air; a sheet forming unit configured to form a sheet by using at least a part of defibrated material that has been defibrated by the defibrating unit; and a flow path configured to transfer the defibration object to the defibrating unit, the flow path having a pipeline unit through which the defibration object passes, an opening having a size through which the defibration object does not pass on a surface of the pipeline unit, and an enclosure unit enclosing the pipeline unit such that the opening is positioned inside. 2. The sheet manufacturing apparatus according to claim 1 , wherein the opening is an opening formed in a mesh unit having a net-like form. 3. The sheet manufacturing apparatus according to claim 2 , wherein the mesh unit is arranged in an entire circumference in a circumferential direction of the pipeline unit. 4. The sheet manufacturing apparatus according to claim 2 , wherein the mesh unit is arranged in a part in a circumferential direction of the pipeline unit. 5. The sheet manufacturing apparatus according to claim 1 , further comprising a crushing unit configured to crush material including fibers, wherein the defibrating unit is configured to defibrate a crushed piece, which has been crushed as the defibration object by the crushing unit, in the air, and the flow path is provided between the crushing unit and the defibrating unit.
