PROBLEM TO BE SOLVED: To provide a sheet production apparatus including a fibrillation unit for fibrillating an object to be fibrillated, and producing a sheet having a practical strength by fibrillation without excessively fibrillating in the fibrillation unit.SOLUTION: A sheet production apparatus includes a fibrillation unit in which an object to be fibrillated is subjected to a dry type fibrillation treatment by rotating a rotation unit. At least, a part of the object to be fibrillated, subjected to the dry type fibrillation treatment, is accumulated and heated to produce a sheet. The rotation unit has a rotator having a plurality of protrusions at an outer periphery and a feeding blade provided at a side part of the rotator. The feeding blade is provided at the side part of the flow-in part side of the object to be fibrillated in the rotator and has a blade part standing in an extension direction of a rotation axis of the rotator. |
