Abstract
Rollers that transport a sheet while heating the sheet, and a separating unit that includes a separating plate and a supporting portion are included. The separating plate has a leading end portion that comes into contact with a second roller of the rollers. The supporting portion supports the separating plate. The separating plate is provided with a slit that absorbs bending due to a thermal expansion difference between the separating plate and the supporting portion.
Claims4
A sheet separating apparatus comprising:
- a pair of rollers that transports a sheet while heating the sheet;
- and
- a separating unit including a separating plate and a supporting portion, the
- a separating plate having a leading end portion that comes into contact with one roller of the pair of rollers, the supporting portion supporting the separating plate,
- the separating plate having a slit that absorbs bending due to a thermal expansion difference between the separating plate and the supporting portion,
- the separating plate being made of polyimide, and
- further comprising a wind-around roller facing the separating plate and the supporting portion, wherein the wind-around roller is arranged such that the sheet that has passed between the pair of rollers passes between the separating unit and the wind-around roller and between the supporting portion and the wind-around roller, and is transported downstream.

A sheet manufacturing apparatus comprising:
- a supply unit that supplies a raw material;
- a deposition unit that accumulates a part of the raw material and forms a sheet;
- a pressing unit that presses the sheet;
- and
- a cutting unit that cuts the sheet,
- the pressing unit including
- a pair of rollers that transports the sheet while heating the sheet, and
- a separating unit including a separating plate and a supporting portion, the separating plate having a leading end portion that comes into contact with one roller of the pair of rollers, the supporting portion supporting the separating plate, and
- the separating plate having a slit that absorbs bending due to a thermal expansion difference between the separating plate and the supporting portion, and
- the separating plate being made of polyimide, and
- further comprising a wind-around roller facing the separating plate and the supporting portion, wherein the wind-around roller is arranged such that the sheet that has passed between the pair of rollers passes between the separating unit and the wind-around roller and between the supporting portion and the wind-around roller, and is transported downstream.
