Description

  The present invention relates to a technique for finishing an inner surface of a building.

The inner surface of a building (in the present application, the term “inner surface” is used to include any of a wall surface, a ceiling surface, and a floor surface, but in the present application, it mainly means a wall surface and a ceiling surface). Finished by covering with a finishing material.
The finishing material is, for example, a finishing sheet that is a tile material, a panel material, or a film material. An example of a finishing sheet that is most frequently used is wallpaper.

  By the way, when covering the inner surface of a building with a finishing sheet, it is usual to affix the finishing sheet on the inner surface using, for example, an adhesive. A process using such a liquid or the like is called a wet process, but such a wet process needs to prevent soiling due to dripping of the adhesive, and has a curing period. There are many troubles such as being necessary. Also, the use of adhesives tends to cause sick house problems.

If such a point is considered, it will be sufficient if a finishing sheet can be attached to the inner surface of a building without going through a wet process. In fact, it has been proposed to finish the inner surface by placing a finishing sheet, which is a membrane material, in front of the inner surface of the building.
In this technique in which the finishing sheet is arranged in front of the inner surface of the building, it has also been proposed that the finishing sheet can be freely attached and detached. By doing in this way, the finishing of the inner surface of the building can be easily performed, and the finishing sheet can be easily replaced when the finishing sheet becomes dirty. This technology with such advantages is expected to have future demand.

The finishing sheet is conventionally fixed in a state of covering the target surface using a gripping material 100 as shown in FIG.
The gripping material 100 is used by being attached to an attachment position that sandwiches a target surface to be finished among the inner side surfaces of the building. The gripping material 100 is long and is attached along two opposite sides of the target surface, which is usually rectangular. The gripping material 100 is a rectangle slightly smaller than the target surface, and covers and covers the target surface with the finishing sheet 200 by gripping and fixing two opposing sides of the finish sheet 200 having elasticity.
The gripping material 100 has the same cross-sectional shape as shown in FIG. 8 at all portions in the length direction. The gripping material 100 includes a fixed portion 110, a first gripping plate 120, and a second gripping plate 130.
The fixed portion 110, the first gripping plate 120, and the second gripping plate 130 are all plate-shaped and are integrally formed of resin.
The fixing part 110 is for fixing the gripping material 100 to an attachment position that sandwiches the target surface. For example, the fixing part 110 is fixed to the attachment position by driving a wood screw 300.
The base end of the second grip plate 130 is directly connected to the fixing portion 110. On the other hand, the first holding plate 120 is fixed to the fixing portion 110 via the connecting portion 140 by being fixed to the distal end of the connecting portion 140 formed in a substantially L-shaped cross section with the base end connected to the fixing portion 110. It is fixed. The first holding plate 120 is fixed to the distal end of the connecting portion 140 at the base end.
The first holding plate 120 and the second holding plate 130 are provided with a slight gap. The end of the finishing sheet 200 is pushed into this gap so that the end of the finishing sheet 200 is held by the gripping material 100.

Such a gripping material 100 is useful in that the finishing sheet 200 can be fixed so as to cover the target surface, and the fixing can be made detachable.
However, the gripping material 100 also has a point to be improved.
As described above, the finishing sheet 200 has elasticity. This is because the finish sheet 200 is covered with the finish sheet 200 that is slightly smaller than the target surface, so that tension is applied to the finish sheet 200 so that wrinkles and undulations do not occur in the finish sheet 200, thereby improving the aesthetics of the finish sheet 200. It is. Therefore, a force directed toward the center of the finishing sheet 200 acts on the end portion of the finishing sheet 200 fixed by the gripping material 100.
When such a force is continuously applied, or when this force temporarily increases for some reason, the finishing sheet 200 is attached to a portion of the gripping material 100 where the first gripping plate 120 and the connecting portion 140 are fixed. A force toward the central direction is applied, whereby the first holding plate 120 moves in a direction away from the second holding plate 130. When such a thing happens, naturally the edge part of the finishing sheet 200 falls out of the holding | gripping material 100. FIG.
Although it is preferable that the finishing sheet 200 can be detached from the gripping material 100 when the finishing sheet 200 is intended to be exchanged, unintentional dropping of the finishing sheet 200 from the gripping material 100 as described above is not preferable.

  This invention makes it the subject to improve the holding material used in order to finish the inner surface by covering the inner surface of a building with a finishing sheet so that unintentional dropping of the finishing sheet can be prevented.

The present invention for solving the above-described problems is as follows.
The present invention is a long material that is attached to and used at an attachment position that sandwiches an object surface to be finished and that is at least a part of an inner surface of a building, and is stretched in a spanning direction connecting the attachment positions. The end surface of the finished sheet, which is a stretched film material, can be gripped along its length direction, and the inner surface of the building is formed by covering the target surface with the finished sheet It is a holding material used for the finishing process.
The gripping material includes a fixing portion that is fixed to the attachment position, and a plate-like first portion that extends in a direction substantially perpendicular to the target surface when the fixing portion is fixed to the attachment position. When the fixing part is fixed to the gripping plate and the mounting position, a plate-like shape that faces the first gripping plate parallel to the first gripping plate and with a slight clearance from the first gripping plate. A second gripping plate, and grips the end portion of the finishing sheet by sandwiching the end portion of the finishing sheet inserted into the gap between the first gripping plate and the second gripping plate. It is like that.
Further, the first grip plate of the grip material includes the fixed portion between the both ends in the direction substantially perpendicular to the target surface and one end thereof, and the connection portions connected to the fixed portion and the other end, respectively. And the other end in the direction substantially perpendicular to the target surface is substantially parallel to the spanning direction when one end in the direction substantially perpendicular to the target surface is moved substantially parallel to the spanning direction. And one end in a direction substantially perpendicular to the target surface moves in a direction opposite to the moving direction.
In such a gripping material, a force toward the center direction of the finishing sheet is applied to the end portion of the finishing sheet fixed by the gripping material, so that the end portion in the direction substantially perpendicular to the target surface of the first gripping plate When the side far from the target surface moves to the center side of the finishing sheet, the side close to the target surface among the ends of the first grip plate in the direction substantially perpendicular to the target surface moves in a direction away from the center side of the finishing sheet. . That is, in this gripping material, the gap between the first gripping plate and the second gripping plate is moved by moving the side farther from the target surface to the center side of the finishing sheet among the end portions in the direction substantially perpendicular to the target surface of the first gripping plate. At the same time, the side closer to the target surface in the direction substantially perpendicular to the target surface of the first gripping plate moves in the direction opposite to the center side of the finished sheet, and the first gripping plate and the first gripping plate The gap between the two gripping plates becomes narrower. In short, the first gripping plate of the present invention performs a seesaw motion around the portion where the first gripping plate and the tip of the connecting portion are connected. Therefore, in this gripping material, when the gap between the first gripping plate and the second gripping plate becomes large and the finish sheet is likely to fall off, the other of the first gripping plate and the second gripping plate is used. The gap becomes smaller at this portion, and the force for holding the finished sheet becomes larger.
Thereby, in the holding material of the present invention, it is possible to prevent an unintended finish sheet from dropping from the holding material based on the tension of the finishing sheet. On the other hand, when the finishing sheet is pulled with a certain force or more in the gap direction between the first gripping plate and the second gripping plate, the movement of the both ends of the first gripping plate as described above does not occur, so that the finishing can be performed without any problem. The sheet can be pulled out of the gripping material. Thereby, this invention also maintains the advantage of the conventional holding | grip material that a replacement | exchange of a finishing sheet can be performed easily.

The connecting portion in the present invention is configured to connect the first gripping plate and the fixing portion to integrate the first gripping plate and the fixing portion, and in a direction substantially perpendicular to the target surface of the first gripping plate. When one end moves substantially parallel to the spanning direction, the other end in the direction substantially perpendicular to the target surface of the first gripping plate is substantially parallel to the spanning direction and one end in the direction substantially perpendicular to the target surface is Any configuration may be used as long as it moves in the direction opposite to the moving direction.
For example, the connecting portion is a plate-like support that extends in the stretching direction when the fixing portion is fixed to the attachment position, and the tip of the connecting portion is positioned away from the center of the finishing sheet. A plate may be provided, and in this case, the first holding plate may be connected to the tip of the support plate.

  As described above, the second gripping plate of the present invention faces the first gripping plate with a slight gap, and the finishing sheet inserted in the gap cooperates with the first gripping plate. And is to be pinched. The second gripping plate plays a role of creating a certain gap with the first gripping plate. As long as this is possible, the second gripping plate is not necessarily integrated with the fixing portion. On the other hand, the second grip plate may be connected to the fixed portion and integrated with the fixed portion. In this way, when the gripping material of the present invention is fixed at the mounting position, the second gripping plate need not be positioned with respect to the first gripping plate.

  The gripping material may have a space in the inside thereof so that the end of the finishing sheet inserted into the gap is not visible from the outside. With such a space, it is possible to improve the aesthetics when finishing the target surface with a finishing sheet.

The fixing portion is for fixing the gripping material to the attachment position, and there is no particular limitation on the configuration thereof as long as it is possible. The fixing part may be plate-shaped. In that case, the second gripping plate may be connected along one end of the fixed portion. In this case, the one end of the fixing portion may protrude slightly from the surface of the second gripping plate that is far from the first gripping plate.
When inserting a finishing sheet between the first gripping plate and the second gripping plate, the end of the finishing sheet is provided with a long enough margin to be pushed into the gap between the first gripping plate and the second gripping plate. After cutting, it is common practice to press a thin plate against the edge of the end of the finished sheet slightly from the center and push the plate into the gap between the first and second holding plates together with the finished sheet. Is. By the way, for example, when the finishing sheet is arranged with the entire surface of the rectangular ceiling as the target surface, the gripping material is fixed to two opposite sides of the ceiling. In this case, it is preferable from the viewpoint of aesthetics to fix the gripping material so that the second gripping plate is brought into contact with the wall surface without a gap, but when the second gripping plate is brought into contact with the wall surface without a gap, the finished sheet It becomes very difficult to perform the above-described operation of pushing the plate into the gap between the first holding plate and the second holding plate. That is, when the plate is pushed into the gap between the first gripping plate and the second gripping plate, if the second gripping plate is in contact with the wall surface, the plate moves in the direction of increasing the gap when the plate is pushed into the gap. However, since only the first gripping plate is used, the force required to push the plate into the gap is increased.
On the other hand, if one end of the fixed part protrudes slightly from the surface of the second gripping plate far from the first gripping plate, the second gripping plate is positioned so as to contact the wall surface without a gap. Even if the gripping material is fixed, a slight gap corresponding to the protruding portion of the fixing portion is generated between the second gripping plate and the wall surface. As a result, when the plate is pushed into the gap between the first gripping plate and the second gripping plate, both the first gripping plate and the second gripping plate move in the direction in which the gap increases. This reduces the force required to push the plate into the gap. One end of the fixing portion can move in a direction in which the second gripping plate escapes from the first gripping plate when the above-mentioned plate is pushed into the gap between the first gripping plate and the second gripping plate, and thereby the first gripping plate And the second gripping plate need only protrude to a length that facilitates the operation of pushing the plate into the gap. In addition, the length of the second gripping plate and the wall surface when the gripping material is arranged along the wall surface (the wall surface is the wall surface when the target surface is the entire ceiling, but this is the case when the target surface is the entire wall surface, etc. It is preferable that the gap generated between the first and second layers is not detrimental to aesthetics.
The length of one end of the fixing portion protruding from the surface of the second gripping plate far from the first gripping plate is about 0.5 to 1.5 mm, preferably about 0.5 to 1.0 mm.

The cross-sectional shape when cut in a plane perpendicular to the length direction of the gripping material may be the same in all parts in the length direction, or may be different for each part in the length direction. It may be. If the cross-sectional shape is the same in all portions in the length direction, the gripping material can be easily processed during manufacturing.
The case where the cross-sectional shape when the gripping material is cut in a plane perpendicular to the length direction is different in each part in the lengthwise direction of the gripping material is, for example, that the first gripping plate or the second gripping plate is of the gripping material. This is a case where it does not exist in a part of the length direction.

The present invention also provides the following gripping materials.
This gripping material is a long material that is attached to an attachment position sandwiched between target surfaces to be finished and is at least a part of the inner side surface of the building, and is a film material having elasticity. The two finishing sheets, the ends of which are respectively stretched on both sides of the long material so as to be along the stretching direction that is perpendicular to the length direction of the long material It is used for the finishing process of the inner surface of the building performed by covering the target surface with the finishing sheet.
The gripping material is configured to extend in a direction substantially perpendicular to the target surface when the fixing portion is fixed to the attachment position, and when the fixing portion is fixed to the attachment position, and Two first gripping plates facing each other with a slight gap therebetween, and the end portions of the finishing sheet inserted into the gap are sandwiched between the two first gripping plates. Thus, the end portion of the finishing sheet is gripped.
In addition, the two first gripping plates of the gripping material are both connected at both ends in the direction substantially perpendicular to the target surface and at one end thereof via connection portions respectively connected at the fixed portion and the other end. When the one end in the direction substantially perpendicular to the target surface moves in a direction substantially parallel to the spanning direction, the other end in the direction substantially perpendicular to the target plane is the spanning direction. And one end in a direction substantially perpendicular to the target surface is moved in a direction opposite to the moving direction.
This gripping material is roughly configured by configuring the second gripping plate in the gripping material described so far in the same manner as the first gripping plate in the gripping material described so far. Such a gripping material can be used by being attached between two adjacent target surfaces, and is useful in that it can grip two finishing sheets covering the two adjacent target surfaces at a time.
The first gripping plate in the gripping material can be configured in the same manner as the first gripping plate in the gripping material described above.

  Hereinafter, preferred first and second embodiments of the present invention will be described with reference to the drawings. In 1st-2nd embodiment, the same code | symbol is attached | subjected to the overlapping part, and the overlapping description shall be abbreviate | omitted suitably.

<< First Embodiment >>
In the first embodiment, the entire rectangular ceiling of a building having a rectangular parallelepiped inner surface is the target surface to be finished, and the entire ceiling is covered with a finishing sheet. In this embodiment, the target surface is a ceiling surface, but is not limited to a ceiling surface, and may be a wall surface or the like. Further, the shape of the target surface is not necessarily rectangular.
FIG. 1 shows a state where the ceiling R is looked up from below. There is a hatched portion in the portion along the wall surface near the opposite side of the ceiling R, and a gripping material to be described later is attached to that portion. That is, in this embodiment, the hatched portion is the attachment position referred to in the present invention. Further, the direction along the straight line perpendicular to both of the two mounting positions parallel to each other in this embodiment, that is, the left-right direction in FIG. In the first embodiment, it has been described above that the entire surface of the ceiling R is the target surface T. To be precise, the portion sandwiched between the hatched portions is the target surface T. Further, it is sufficient that the gripping material is attached along a pair of opposing sides of the target surface T, but four gripping members may be attached along two opposing sides of the target surface T, that is, four.
The finishing sheet can be made into an appropriate shape according to the shape of the target surface T. However, in the first embodiment, the finishing sheet is a rectangular sheet material that is slightly shorter in the stretching direction than the target surface T. In general, the shape of the finishing sheet may be such that the length in the stretching direction is slightly smaller than the length of the target surface in the direction. The finishing sheet has elasticity. The finishing sheet in this embodiment is, for example, a polyester woven fabric. The finishing sheet may be a knitted fabric having elasticity.

Next, the configuration and usage method of the gripping material will be described. FIG. 2 is a longitudinal sectional view showing a state in which the gripping material 10 is attached to a portion along the wall surface, which is the attachment position of the ceiling R across the target surface T.
In this embodiment, the gripping material 10 is formed as an integral body made of resin. In this embodiment, the cross-sectional shape when cut by a plane perpendicular to the length direction of the gripping material 10 is not necessarily limited to this, but is the same in any part.

  The gripping material 10 includes a fixed portion 11, a first gripping plate 12, a second gripping plate 13, and a connection portion 14. The fixed portion 11, the first holding plate 12, and the second holding plate 13 are all plate-shaped. The connection portion 14 has a substantially L-shaped cross section and includes a connection plate 14A and a support plate 14B. Both the connection plate 14A and the support plate 14B are plate-shaped.

The fixing portion 11 is fixed to the mounting position in a state where the outer surface is in contact with the mounting position of the ceiling R. By fixing the fixing portion 11 at the mounting position, the gripping material 10 is fixed at the mounting position of the ceiling R.
The fixing portion 11 may be fixed to the mounting position in any way, but in this embodiment, the fixing portion 11 is moved to the mounting position by screwing the wood screw M into the ceiling R through the fixing portion 11. It is supposed to be fixed.
In order to make this possible, the fixing portion 11 projects from the connection plate 14 </ b> A in a direction toward the center of the target surface T.
Further, the fixing portion 11 slightly protrudes from the second gripping plate 13 in a direction away from the center of the target surface T. In this embodiment, the length that the fixing portion 11 protrudes from the second gripping plate 13 in the direction away from the center of the target surface T is approximately 0.5 mm, but this length is 0.5 mm to 1 mm. It may be determined appropriately between about 5 mm, more preferably between about 0.5 mm and 1.0 mm.
As described above, in this embodiment, the gripping material 10 is fixed along the wall surface. Therefore, when fixing the gripping material 10 to the wall surface, prior to that, the end of the fixing portion 11 on the side to which the second gripping plate 13 is connected is placed along the wall surface, and in this state, the fixing portion 11 is fixed. And wood screws M are screwed into the ceiling R. Since the end of the fixing portion 11 on the wall surface slightly protrudes from the second holding plate 13 as described above, in this state, the second holding plate 13 perpendicular to the fixing portion 11 and A slight gap corresponding to the length of the fixed portion 11 protruding from the second gripping plate 13 is left between the wall surface.

The first holding plate 12 and the second holding plate 13 are opposed to each other in a positional relationship such that they are parallel to each other with a slight gap therebetween. In this embodiment, the first holding plate 12 and the second holding plate 13 are perpendicular to the fixed portion 11. A finishing sheet is inserted into the gap between the first holding plate 12 and the second holding plate 13 as will be described later. In this state, the first grip plate 12 and the second grip plate 13 sandwich the finished sheet. In order to make it possible, the width of the gap between the first gripping plate 12 and the second gripping plate 13 is slightly narrower than the thickness of the finished sheet.
In order to securely hold the finishing sheet when the finishing sheet is sandwiched between the first gripping plate 12 and the second gripping plate 13 on both the opposing surfaces of the first gripping plate 12 and the second gripping plate 13. Can be devised. For example, the opposing surfaces of the first holding plate 12 and the second holding plate 13 are roughened to increase the friction coefficient with respect to the finished sheet, or the opposing surfaces of the first holding plate 12 and the second holding plate 13 are Sawtooth-shaped unevenness toward the R side can be provided.
The connecting portion 14 is for fixing the first holding plate 12 to the fixing portion 11. In this embodiment, the connection plate 14 </ b> A constituting a part of the connection portion 14 is perpendicular to the fixed portion 11. Further, the support plate 14 </ b> B is configured to be parallel to the fixed portion 11.
The support plate 14B is connected to the connection plate 14A at the base end, and is fixed to the first gripping plate 12 at the tip end. In this embodiment, the support plate 14 </ b> B is connected to the center in the direction perpendicular to the fixing portion 11 of the first gripping plate 12. However, the support plate 14 </ b> B may be connected anywhere on the first holding plate 12 as long as it is other than both ends in the direction perpendicular to the fixed portion 11 of the first holding plate 12. However, it is preferable that the support plate 14B is fixed in the middle in the direction perpendicular to the fixing portion 11 of the first gripping plate 12.

Next, the end of the finished sheet is gripped by the two gripping materials 10.
In order to grip the end portion of the finishing sheet S with the two gripping materials 10, a procedure as shown in FIG. 3 may be executed.
In order to grip the end portion of the finishing sheet S with the gripping material 10, the end portion of the finishing sheet S is pulled to the lower side of the gap between the first gripping plate 12 and the second gripping plate 13 (FIG. 3A), In this state, the finishing sheet S is inserted into the gap between the first gripping plate 12 and the second gripping plate 13 using a pushing tool 30 as shown in FIG. The pushing tool 30 is obtained by attaching a thin metal blade 32 to a grip portion 31 that is shaped to be easily gripped by hand.
Specifically, for all portions in the length direction of the gripping material 10, for example, little by little from one end side to the other end side in the length direction of the gripping material 10, for each end (a little closer to the center) of the finishing sheet S. The tip of the pushing tool 30 is pushed into the gap between the first holding plate 12 and the second holding plate 13. At this time, since both the first holding plate 12 and the second holding plate 13 move away from each other, this operation can be performed relatively easily. This operation is repeated about 3 to 4 times for the same place.
Then, the end portion of the finishing sheet S changes from the state of FIG. 3B to the state of FIG. 3C, and when the blade 32 of the pushing tool 30 is removed, the first gap of the gripping material 10 is finally obtained. It is all housed in the space above the grip plate 12 and the second grip plate 13 (the space surrounded by the fixed portion 11, the first grip plate 12, the second grip plate 13, and the connection portion 14), and FIG. It will be in the state shown in.
By performing such an operation on both of the two gripping materials 10, both ends of the finishing sheet S are gripped by the gripping material 10, and the target surface T is covered with the finishing sheet S.

When a force directed toward the center of the finishing sheet S acts on the portion of the finishing sheet S stretched in this way held by the gripping material 10, as shown in FIG. 5 moves in the direction indicated by X in FIG. 5, which is the substantially central direction of the finishing sheet S. Then, the upper end portion of the first gripping plate 12 moves in the direction indicated by Y in FIG. At this time, the gap between the first gripping plate 12 and the second gripping plate 13 in the vicinity of the upper end of the first gripping plate 12 becomes narrow, and the first gripping plate 12 and the second gripping plate 13 remove the finishing sheet S located in that portion. The holding force increases.
Therefore, even if a force toward the center of the finishing sheet S acts on the portion of the finishing sheet S gripped by the gripping material 10, the finishing sheet S does not fall off the gripping material 10. In addition, the amount of movement in the X direction of the lower end of the first gripping plate 12 increases as the force toward the center of the finishing sheet S acting on the portion gripped by the gripping material 10 of the finishing sheet S increases. Along with this, the amount of movement of the upper end of the first gripping plate 12 in the Y direction increases. That is, as the force toward the center direction of the finishing sheet S acting on the portion of the finishing sheet S gripped by the gripping material 10 increases, the first gripping plate 12 and the second gripping plate 12 near the upper end of the first gripping plate 12 are increased. Since the gap between the gripping plates 13 becomes narrower and the force that the first gripping plate 12 and the second gripping plate 13 hold the finishing sheet S located in that portion becomes larger, the finishing sheet S cannot fall off. Become.

  On the other hand, when the portion of the finishing sheet S gripped by the gripping material 10 is pulled downward in FIG. 2, the above-described movement at the upper and lower ends of the first gripping plate 12 does not occur. Accordingly, as described above at the upper and lower ends of the first gripping plate 12, such as when the direction in which the finishing sheet S is pulled out matches the direction of the gap between the first gripping plate 12 and the second gripping plate 13. If the direction is set so as not to cause movement, it is easy to intentionally pull out the finishing sheet S from the gripping material 10.

<< Second Embodiment >>
Next, the gripping material 20 according to the second embodiment will be described.
FIG. 6 shows the gripping material 20 in a state of being attached to the attachment position of the ceiling R.
Similar to the gripping material 10 of the first embodiment, the gripping material 20 of the second embodiment includes a fixing portion 11, a first gripping plate 12, and a connection portion 14. The difference is that the gripping material 10 of the first embodiment has only one first gripping plate 12 and one connecting portion 14, whereas the gripping material 20 of the second embodiment has two of them. The gripping material 20 according to the second embodiment does not include the second gripping plate 13 included in the gripping material 10 according to the first embodiment.
That is, the gripping material 20 of the second embodiment has a configuration in which the first gripping plate 12 and the connection portion 14 are provided instead of the second gripping plate 13 of the gripping material 10 of the first embodiment. The two first gripping plates 12 face each other with a gap corresponding to that between the first gripping plate 12 and the second gripping plate 13 of the gripping material 10 in the first embodiment.
The gripping material 20 uses both sides (the left-right direction in FIG. 6) as the target surface T. The finishing sheet is stretched in a direction perpendicular to the length direction of the gripping material 20. The gripping material 20 is attached to a portion sandwiched between the target surfaces T as an attachment position.
The configurations of the fixing portion 11, the first gripping plate 12, and the connection portion 14 in the gripping material 20 of the second embodiment are basically the same as in the case of the first embodiment.

The method of using the gripping material 20 in the second embodiment is basically the same as in the first embodiment.
In using the gripping material 20, the gripping material 20 is attached to an appropriate mounting position, and then the end of the finished sheet S is placed in the gap between the two first gripping plates 12 as in the first embodiment. Push in. In this embodiment, two finishing sheets S are pushed into the gap, but the pushing is performed for one of the two finishing sheets S and then the other.
A state in which the finishing sheet S is gripped by the gripping material 20 is shown in FIG.
