- at least one plate heater that generates heat so as to heat the portion and a chamber that houses the guide roller and the plate heater.
- the chamber includes an outer wall surrounding the guide roller and the plate heater, in which an opening that communicates the inside and the outside of the outer wall is formed.
- the outer wall includes a front side wall and a rear side wall that are respectively positioned on both sides of the guide roller and the plate heater in the front-rear direction when the direction parallel to the rotation center axis of each guide roller is the front-rear direction.
- the rear side wall respectively support an upper roller support portion rotatably supporting the axial end portion of each upper roller, and an axial end of each lower roller at a position below the upper roller support portion.
- a lower roller support part that rotatably supports the part.
- the opening includes an inter-roller opening formed in a region between the upper roller support portion and the lower roller support portion in at least one of the front side wall and the rear side wall.
- the opening between the rollers of this apparatus is formed between the upper roller support portion and the lower roller support portion on at least one of the front side wall and the rear side wall, and in the traveling direction between the upper roller and the lower roller. Since the plurality of film forming material portions and the plate heater that cross over each other are crossed on the front side or the rear side thereof, each guide roller can be supported by the front side wall and the rear side wall, and wide through the opening between the rollers. It is possible to effectively and efficiently perform maintenance work for each guide roller and plate heater and so-called paper passing work for the film forming material (work for passing the film forming material to each guide roller) over a range.
- the opening between the rollers is formed on both the front side wall and the rear side wall. This not only facilitates the maintenance work, but also reduces the difference in rigidity between the front side wall and the rear side wall, thereby equalizing the degree of deformation of the front side wall and the rear side wall due to the load received from each guide roller, This makes it possible to keep the level of each guide roller high.
- the degassing apparatus further includes a support member that supports the chamber from below and forms a working space below the lower opening. The combination of the support member and the lower opening enables maintenance of each guide roller and plate heater not only from the upper side of the chamber but also from the lower side.
- the degassing apparatus preferably includes a scaffold for performing work through the upper opening, and the scaffold is vertically moved from the opening between the rollers on at least one side in the front-rear direction of the chamber. It is preferable to be arranged at a position deviating from the above.
- the scaffold provided at such a position does not obstruct maintenance work through the opening between the rollers, and allows other process units to be arranged on at least one side of the chamber in the traveling direction. However, the operation through the upper opening can be facilitated.
- the degassing apparatus according to the present invention may be integrated as a part of the film forming apparatus or may be configured as a dedicated apparatus independent of the film forming apparatus.
- the degassing apparatus according to the present invention includes, in addition to the guide rollers, an unwinding roll that unwinds the film-forming material to the guide rollers while rotating about an axis extending in the front-rear direction, and extends in the front-rear direction.
- a winding roll for winding the film-forming material from the guide rollers while rotating around the axis, and the unwinding roll and the winding roll are accommodated in the chamber together with the guide rollers. May be.
- the unwinding roll and the winding roll are provided so as to be aligned with each other in the left-right direction perpendicular to the rotation center axis of each guide roller at a position deviated from the respective guide rollers in the vertical direction.
- the opening left and right openings respectively formed on the left and right sides of the outer wall are formed, and the left and right openings have a size that allows the unwinding roll and the winding roll to be taken in and out through the left and right openings, respectively. Is preferred.
