Description

  The present invention relates to a wet tissue and a wet tissue manufacturing method.

In order to store the wet tissue impregnated with the chemical solution in the container, the method of folding the wet tissue into three is folded in approximately half and folded in the opposite direction, and the manufacturing method thereof. (Patent Documents 1 to 4). Further, a structure for folding wet tissue, a folded plate, and the like have been proposed. (Patent Documents 1 to 6)
Japanese Patent No. 2951187 (FIG. 8 etc.) Japanese Patent No. 2777871 (FIG. 6 etc.) US Pat. No. 3,401,928 (FIG. 9 etc.) US Pat. No. 3,462,043 (FIG. 9 etc.) JP 2002-102107 A (FIG. 1 etc.) JP 2001-286410 A (FIG. 1 etc.)

However, in Patent Document 2, there is a problem that the manufacturing process is complicated because the wet tissue folding method is complicated.
Further, in Patent Document 1, although the folding method is not complicated, there is a problem in that the production efficiency is poor because it is cut into units of one wet tissue and then folded in three and overlapped with other wet tissues.
Therefore, it is conceivable to improve the production efficiency by folding as in Patent Document 5 after being folded according to the folding method of Patent Document 1.
However, when the wet tissue is transported in the X direction of FIG. 1 of Patent Document 5, a force is applied in the X direction of the wet tissue, so that there is a problem that the wet tissue extends along the transport direction and becomes defective. It was.
In addition, regarding how to fold wet tissue, when multiple layers of three-folded wet tissue are stacked, the folded portions overlap each other, and if the wet tissue height after stacking is uneven, it is stable during distribution and use There was also a problem that it was not possible to place them, for example, they could not be stacked.

  Therefore, even if a plurality of sheets are folded in three, the overall thickness does not become non-uniform, the production efficiency can be increased, and the wet tissue and wet tissue manufacturing that is difficult to extend in the conveying direction in the production process is difficult. It aims to provide a method.

  According to the first aspect of the present invention, there is provided a wet tissue that is folded and accommodated in a moisture-impermeable bag having an outlet, and each wet tissue is located on the outlet side. A first region disposed in the first region, a second region disposed below the first region, and a third region disposed below the second region, wherein the second region is The first region and the second bent portion are connected to each other, the third region is connected to the second region and the second bent portion, and the first bent portion and the second bent portion are connected to each other. The bent portions are arranged substantially parallel to each other, and the fibers of the wet tissue are arranged along a folding direction which is an arrangement direction of the first bent portion and the second bent portion, and the first region The length in the width direction, which is the direction orthogonal to the folding direction, is The length in the width direction of the second region is equal to or less than half the length in the width direction of the first region. Another wet tissue having a length that is longer than the length of the third region in the width direction and having an end positioned in the opposite direction between the first region and the second region. This is achieved by a wet tissue characterized in that it is arranged so that a part of the first region is sandwiched.

According to the said structure, a 1st bending part and a 2nd bending part are mutually arrange | positioned substantially parallel,
The wet tissue fibers are arranged along the folding direction which is the arrangement direction of the first bent portion and the second bent portion. For this reason, the first bent portion and the second bent portion are formed without cutting the long wet tissue sheet into a size for each wet tissue, and conveyed on the machine along the folding direction. Even if it makes it, since the sheet | seat body for wet tissue does not extend in relation to the directivity of a fiber, it can prevent that wet tissue becomes defective.
In addition, the directionality in the fiber of the wet tissue shown here has shown that there are many fibers arrange | positioned toward the same direction in the used fiber.
Moreover, the production efficiency of wet tissue increases by cutting after forming the 1st bending part and the 2nd bending part in this way.
That is, in the above-described configuration, as in the conventional case, since the wet tissue sheet body is cut and then the first bent portion and the second bent portion are formed and stacked, it can be continuously produced. Production efficiency can be remarkably increased.

Moreover, in the said structure, the length of the width direction which is a direction orthogonal to the folding direction of a 1st area | region is comprised longer than the length which combined the length of the width direction of a 2nd area | region and a 3rd area | region, The length in the width direction is less than half the length in the width direction of the first region, and is longer than the length in the width direction of the third region, between the first region and the second region. The other regions of the other wet tissue are arranged so as to be sandwiched.
For this reason, for example, the second region disposed below the first region of the wet tissue disposed on the outlet side only occupies less than half of the lower surface of the first region. In addition, other wet tissue sandwiched between the first region and the second region of the wet tissue and disposed in the opposite direction also occupies less than half of the lower surface of the first region. Only. For this reason, the 2nd area | region of the said wet tissue arrange | positioned on the lower surface of the wet tissue arrange | positioned at the extraction side and the 2nd area | region of another wet tissue do not mutually overlap.
And since 2nd area | regions do not overlap, the 3rd area | region narrowed rather than the 2nd area | region does not overlap.
Therefore, non-uniformity in the length of the wet tissue in the overlapping direction caused by the second region and the third region of different wet tissues overlapping each other does not occur.
For this reason, the right-and-left balance in the bag body which accommodated the wet tissue does not become non-uniform, and a state where it can be stably placed can be achieved.

Moreover, in the said structure, since the length of the width direction of a 2nd area | region is comprised longer than the length of the width direction of a 3rd area | region, the edge part of a 3rd area | region does not protrude outward from a 1st area | region. In the second region.
For this reason, the end of the third region protrudes and is prevented from being bent inadvertently in the bag body, and the third region is always arranged in a certain range on the left and right, and can be stably placed.
As described above, in the above-described configuration, even if a plurality of sheets are stacked in a three-fold state, the overall thickness does not become non-uniform, the production efficiency can be increased, and the production process is difficult to extend in the conveying direction. Difficult wet tissue can be provided.

  Preferably, according to a second aspect of the present invention, in the configuration of the first aspect, the first region, the second region, and the third region are provided, and the first region and the second region are between the first region and the second region. A plurality of the wet tissues folded so as to sandwich a part of the first region of another wet tissue are stacked to form a wet tissue group, and the wet tissue group is compressed in the stacking direction. It is a wet tissue characterized by being.

  According to the above configuration, since the wet tissue group is compressed in the stacking direction, the first region, the second region, and the third region of each wet tissue in the wet tissue group are stuck to each other with a weak force. Thus, the folded state is fixed and stabilized.

  Preferably, according to the invention of claim 3, in the configuration of claim 1, the wet tissue group is configured to be compressed in the stacking direction with a gap therebetween.

According to the above configuration, the wet tissue group is configured to be compressed in the stacking direction with a space therebetween, so that the wet tissue group is strongly between the first region, the second region, and the third region of each wet tissue. A sticky part and a weakly sticky part are formed.
That is, when the user pulls out the wet tissue from the take-out port, the portion strongly attached in the same direction as the direction in which the wet tissue is drawn out and the portion attached weakly are arranged in parallel. Therefore, since the positional relationship between the strongly sticking portion and the weakly sticking portion of each wet tissue is the same for the user, a so-called pop-up that can be reliably and continuously taken out can be performed, and the wet tissue can be easily taken out.

  According to a fourth aspect of the present invention, there is provided a sheet body supplying step in which a plurality of sheet body supply sections supply a plurality of long wet tissue sheets, and a plurality of chemical liquid impregnation sections are the plurality of sheets. The chemical liquid impregnation step of impregnating the wet tissue sheet body supplied from the body supply section with the chemical liquid and the first folding section are formed in the bag body when the manufactured wet tissue is accommodated in the bag body. A first folding step for forming a first bent portion for connecting a first region disposed on the upper side on the take-out side and a second region disposed on the lower side of the first region; and a second folded portion A second folding step of forming a second bent portion that connects the second region and a third region disposed below the second region, and a sandwiching portion includes the first region and the second region. Between the second region, the end is opposite A sandwiching step for sandwiching a part of the first region of the other wet tissue sheet disposed so as to be positioned, and the first region, the second region, and the second region by the first folding unit and the second folding unit. A third region is formed, and a plurality of wet tissue sheet bodies sandwiching a part of the first region of another wet tissue sheet body by the sandwiching portion are stacked to form a wet tissue sheet body group, and a sheet body cutting unit Cutting the wet tissue sheet body into the wet tissue size of the unit of use to form a wet tissue group, and the bag forming section converts the wet tissue group into a moisture-impermeable bag body. And the first folded portion and the second folded portion are arranged substantially parallel to each other, and the wet tissue fibers Is arranged along the folding direction, which is the arrangement direction of the first bent portion and the second bent portion, and the length in the width direction which is a direction orthogonal to the folding direction of the first region is The second region and the third region are longer than the total length in the width direction, and the width direction length of the second region is the length of the first region in the width direction. The wet tissue manufacturing method is characterized in that the length is less than half and is longer than the length of the third region in the width direction.

  Preferably, according to the invention of claim 5, in the structure of claim 4, the compressing section includes a compression step of compressing the wet tissue sheet body group in the stacking direction. is there.

  Preferably, according to the invention of claim 6, in the structure of claim 5, the compression structure includes an interval compression step of compressing the wet tissue sheet group in the stacking direction with an interval therebetween. This is a wet tissue manufacturing method.

  Preferably, according to the invention of claim 7, in the configuration of any one of claims 4 to 6, the sheet body cutting portion compresses the wet tissue sheet body group in the stacking direction at intervals. In addition, the wet tissue manufacturing method is characterized in that the wet tissue sheet body group is cut into wet tissue sizes in units of use to form the wet tissue group.

  According to the said structure, a manufacturing process can be simplified and production efficiency improves remarkably.

  In the present invention, even if a plurality of sheets are folded in three, the overall thickness does not become non-uniform, and the production efficiency can be increased. There is an advantage that a tissue manufacturing method can be provided.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

(First embodiment)
FIG. 1 is a schematic explanatory view showing a state in which a wet tissue group 20 in which a plurality of folded wet tissues are stacked is housed in a storage bag according to an embodiment of the present invention, and FIG. It is a schematic explanatory drawing which shows the folding state and lamination | stacking state of the wet tissue in a storage bag, FIG.2 (b) is a schematic explanatory drawing which shows the state which opened the wet tissue.
As shown in FIG. 1 which is a half-section perspective view, in the present embodiment, for example, a storage bag 11 is used which is a bag body into which wet tissues 10a, 10b, 10c and the like to be described later are placed.
The storage bag 11 is made of a moisture-impermeable material and can be deformed. Further, on the upper surface of the storage bag 11, a take-out port 11 a having a substantially elliptical shape or a substantially oval shape for a user to take out the wet tissue 10 a or the like is formed.
The wet tissue 10a taken out from the take-out port 11a is folded while sandwiching a part of the wet tissue 10b etc. arranged below it. This folding method is called, for example, modified Z-folding.

In this way, since the wet tissue 10a disposed above sandwiches a part of the lower wet tissue 10b, when the user pulls out the upper wet tissue 10a, the lower wet tissue 10b is also taken out. It moves to the direction discharged | emitted from 11a, and the one part protrudes from the extraction port 11a, and is arrange | positioned.
Therefore, when the user subsequently takes out the wet tissue 10b, the wet tissue 10b is configured to be easily taken out by the user because a part of the wet tissue 10b protrudes from the outlet 11a. Such a relationship is the same for the stacked wet tissues 10c and lower, so that a part of the next wet tissue 10c and the like is always held at a position protruding from the outlet 11a.
For this reason, the user can easily take out the wet tissue 10a and the like until the end. Such a configuration is called, for example, a pop-up type.
Such wet tissue 10a and the like are made of a nonwoven fabric impregnated with a chemical solution, and the nonwoven fabric used in the wet tissue 10 has fibers oriented in the direction Y in which each bent portion extends, and is in the direction of being drawn out. With respect to the width direction X, it is configured so that it is difficult to extend in the direction Y in which each bent portion extends.

The pop-up deformation Z-folding of the wet tissue 10a will be described below.
As shown in FIG. 2 (a), the wet tissue 10a includes a first region 12a disposed on the upper side on the outlet 11a side, a second region 13a disposed on the lower side of the first region 12a, And a third region 14 a disposed below the two regions 12.
As shown in FIG. 2, the second region 13a of the wet tissue 10a is connected to the first region 12a via the first bent portion 15a.
The third region 14a is connected to the second region 13a via the second bent portion 16a.
By the way, as shown in FIG. 1, the 1st bending part 15a and the 2nd bending part 16a are arrange | positioned substantially parallel mutually. Specifically, the first bent portion 15a and the second bent portion 16a are arranged substantially in parallel along the arrow Y direction (folding direction) in FIG. 1, and are in the same direction as the longitudinal direction of the outlet 11a. Thus, it is arranged substantially parallel to the edge of the wet tissue 10a for the user to pull out.

An arrow X direction (width direction) in FIG. 1 is a direction orthogonal to the above-described folding direction (Y direction). The length L1 in the width direction of the first region 12a shown in FIG. 2A is a length obtained by combining the length L2 in the width direction of the second region 13a and the length L3 in the width direction of the third region 14a. Longer than that.
The length L2 in the width direction of the second region 13a is not more than half the length L1 in the width direction of the first region 12a and is longer than the length L3 in the width direction of the third region 14a. Has been.
Further, as shown in FIG. 2 (a), it is disposed between the first region 12a and the second region 13a of the wet tissue 10a, that is, inside the first bent portion 15a so that the end portion is positioned in the opposite direction. The other wet tissue, for example, the region on the edge side which is a part of the first region 12b of the wet tissue 10b is arranged so as to be sandwiched.

As shown in FIG. 2B, in the expanded state in which the wet tissue 10a is expanded, the first region 12a in the width direction is divided by one end edge (left side in the figure) and the first bent portion 15a. The length L2 in the width direction of the second region 13a divided by the first bent portion 15a and the second bent portion 16a with respect to the length L1, the second bent portion 16a and the other edge (see FIG. The length L3 in the width direction of the third region 14a divided by the right side in FIG.
At this time, the ratio of L1, L2, and L3 is such that L2 + L3 is in the range of 75 to 95, where L1 is 100.
If L2 + L3 is larger than this range, the second bent portion 16a of the wet tissue 10a and the other wet tissue 10b facing each other overlap, and only the central region of L1 becomes high.
Moreover, if L2 + L3 is larger than the above-mentioned range, the area where the wet tissues 10a and 10b are in contact with each other is increased as the other wet tissues 10b are more sandwiched.
In this case, when the wet tissue 10a is taken out from the take-out port 11a, the so-called slip phenomenon that other wet tissue 10b comes out in a sticking state may increase.

On the other hand, if L2 + L3 is smaller than this range, when the other wet tissue 10b is taken out from the take-out port 11a, the other wet tissue 10b is removed when the other wet tissue 10b is caught in the first bent portion 15a. There is a risk that pop-ups will not be possible.
Further, the ratio of L2 and L3 is in the range of 75 to 95, where L2 is 100.
When L3 is larger than this range, the other edge of the third region 14a is positioned outside the first bent portion 15a, and the edge is not intended in the state of being accommodated in the storage bag 11. There is a possibility that it will break in the state and affect the withdrawal from the outlet 11a.
On the other hand, when L3 is smaller than this range, not only can it not be stably placed, but also the outer surface of the third region 14a reliably contacts the first region 12c of the next wet tissue 10c at the time of pop-up. This may not be possible and may affect the withdrawal from the outlet 11a.

In addition, after each wet tissue 10 is folded and stacked, compression is applied from above and below to stabilize the overlap of the wet tissue 10 and to make it compact and to be properly attached.
In this compression, not only the entire surface is compressed, but also a plurality of intermittent compression regions 143 extending in the width direction (X direction) are formed at intervals, and here, four locations are formed.
For this reason, when the wet tissue 10a is pulled out from the take-out port 11a, the strongly sticking portion and the weakly sticking portion are arranged side by side in the direction in which the wet tissue 10a is pulled out, and there is an appropriate sticking partially. Therefore, the user can take out the wet tissue 10a and the like stably and continuously.

With this configuration, when the user pinches and pulls the edge of the first region 12a of the wet tissue 10a of FIG. 2 from the outlet 11a, first, the first region 12a is the first region of the other wet tissue. It is peeled off from the upper surface of 12b and moves upward.
At this time, the second region 12b also starts to move upward at the same time, but the third region 14a is attached to the upper surface of the first region 12c of the wet tissue 10c located next by a weak force, so the first bending is performed. While the angle of the portion 15a begins to open first, the edge of the first region 12b of the other wet tissue 10b begins to be pulled out while sticking to the second region 13a.
Further, when the user pulls out the wet tissue 10a, the sticking of the third region 14a to the wet tissue 10c is peeled off, and the entire wet tissue 10a is pulled out in an open state as shown in FIG. At the same time, the end of the first region 12b of the wet tissue 10b sandwiched between the first region 12a and the second region 13a is both pulled out from the outlet 11a, and the resistance at the outlet 11a whose width is narrowed. Therefore, the structure is separated from the wet tissue 10a.

Further, in this way, about 60 to 100 wet tissues 10a and the like are folded into a deformed Z-fold, and when a part of the lower wet tissue is sandwiched, a single unit as shown in FIG. The wet tissue group 20 is formed and accommodated in the storage bag 11. At this time, the first region 12a of the wet tissue 10a is arranged in the opening of the outlet 11a sealed with a label (not shown).
The user may remove the label from the storage bag 11 in which the wet tissue group 20 is stored, and store it in a molded storage container having a sealing function such as an opening / closing lid (not shown). The label may be opened and closed in the state of the storage bag 11.

FIG. 3 is a schematic diagram showing a wet tissue manufacturing apparatus 100 according to the present embodiment. As shown in FIG. 3, for example, sheet body supply rolls 110a to 110f are sheet body supply bodies that are formed into a substantially cylindrical shape by winding a long wet tissue sheet body 111a (see FIG. 4). Has been placed. Specifically, for example, 60 sheet body supply rolls 110a and the like are formed according to the number of wet tissue layers.
As described above, the belt-shaped wet tissue sheet body 111a and the like supplied from the sheet body supply roll 110a and the like are folded by the folding mechanism (details will be described later) shown in FIG. For example, 60 sheets are stacked.
FIG. 3 shows only a part of the sheet body supply roll 110a and the folding mechanism 120a and the like, but the following description will be made with reference to FIG.
For example, the wet tissue sheet body 111a and the like supplied from the sheet body supply roll 110c in FIG. 3 is a wet tissue sheet body 111c corresponding to the wet tissue 10c in FIG. 2 (an example of a sheet body supply process). That is, the wet tissue sheet body 111 supplied from the sheet body supply roll located on the downstream side in the manufacture indicated by the arrow M direction is positioned above the laminated wet tissue 10.
The wet tissue sheet body 111c is folded as shown in FIGS. 1 and 2 by the folding mechanism 120c. Specifically, the first region 12c, the second region 13c, and the third region 14c shown in FIG. 2 are formed in the wet tissue sheet 111c.
The wet tissue sheet body 111c folded in this way and formed with the first region 12c, the second region 13c, and the third region 14c is conveyed in the direction of arrow M in FIG.

In addition, for example, the wet tissue sheet body 111b supplied from the sheet body supply roll 110b of FIG. 3 is similarly formed by folding the first region 12b, the second region 13b, and the third region 14b by the folding mechanism 120b. As described above, when the first region 12b and the second region 13b are folded, the edge side of the first region 12c of the already formed wet tissue sheet 111c is sandwiched and conveyed in the direction of arrow M.
The wet tissue sheet body 111a supplied from the sheet body supply roll 110a is similarly folded by the folding mechanism 120a, and conveyed in the direction of the arrow M with the first region 12b formed by the folding mechanism 120b interposed therebetween. .
That is, the folding mechanism 120a and the like are arranged for each sheet body supply roll 110a in this way, and are folded by sandwiching the first region 12c and the like of the already folded wet tissue sheet being conveyed. The wet tissue sheet body group 112 (see FIGS. 3 and 4) in which the wet tissue sheet bodies 111a and the like are stacked can be formed. In other words, if a set of 60 sheet body supply rolls 110a and the like and a folding mechanism 120a and the like are arranged on the line in FIG. 3, a wet wet sheet body 111a and the like corresponding to the number of sets will be provided. The tissue group 112 for tissue can be formed.

In this manner, for example, the wet tissue sheet group 112 in which 60 sheets of wet tissue sheets 111a and the like are stacked is further conveyed in the direction of the arrow M on the line.
The transported wet tissue sheet body group 112 applies a force for transporting by the compression roller 130 of FIG. 3, and the stacking direction (stacking direction) of the wet tissue sheet body group 112 corresponding to the vertical direction of FIG. ) And reduced in thickness.
That is, the compression and thinning of the wet tissue sheet group 112 is an example of a compression process in which the compression roller 130 compresses the wet tissue sheet group 112 in the stacking direction.
By compressing the wet tissue sheet group 112 with the compression roller 130 in this way, the first region 12a, the second region 13a, etc., the third region 14a, etc. of each wet tissue sheet 111a, etc. are weak in each other. In this case, the state of being closely attached, sticking and folding is fixed, and the laminated state is made stable.

The wet tissue sheet body group 112 compressed by the compression roller 130 is conveyed on the line in the direction of the arrow M in FIG. 3 and further compressed by the intermittent compression roller 140. As shown in FIG. 3, the intermittent compression roller 140 is configured to compress the wet tissue sheet group 112 conveyed on the line from above and below.
Specifically, two belts 141 and 141 are configured to draw an endless track along the transport direction (the direction of arrow M) above and below the wet tissue sheet group 112 to be transported.
A large number of convex portions 142 are formed on the two belts 141 and 141 at regular intervals, and a force for sandwiching and transporting the wet tissue sheet group 112 between the multiple convex portions 142. It is comprised so that it may compress from the upper and lower sides.
Therefore, since the wet tissue sheet group 112 is compressed only by the convex portions 142 of the intermittent compression roller 140, the wet tissue sheet body group 112 is compressed at intervals, and specifically, compressed by the convex portions 142. 1, the intermittent compression regions 143 and 143 of the wet tissue group 20 in FIG. 1 are compressed. Here, four portions are compressed so as to extend in the width direction X. (There are two places on the drawing, but it is better to have four places.)
The step in which the wet tissue sheet group 112 is compressed with an interval is an example of an interval compression step in which the wet tissue sheet group 112 is compressed in the stacking direction with an interval.

Thus, the first region 12a, the second region 13a, the third region 14a, etc. of the wet tissue sheet 111a, etc., of the wet tissue sheet group 112 compressed by the intermittent compression roller 130 are intermittently compressed. The regions 143 and 143 are relatively strongly attached, and the other portions are attached weakly.
Accordingly, when the user pulls out the wet tissue 10a from the take-out port 11a, a portion (intermittent compression region 143) that strongly sticks in the same direction as the direction in which the wet tissue 10a is pulled out and a portion that weakly sticks are arranged in parallel. Has been.
That is, for the user, since the positional relationship between the strongly stuck portion (intermittent compression region 143) and the weakly stuck portion of each wet tissue 10a and the like is the same, so-called pop-up that can be reliably and continuously taken out can be performed, The wet tissue group 20 is easily removed.
Further, since the convex portion 142 of the intermittent compression roller 130 compresses the wet tissue sheet group 112 from above and below to form a relatively strong compression region 143, the thickness of the entire wet tissue sheet group 112 can be made more compact. It can be made thin.

The wet tissue sheet body group 112 having an appropriate thickness by the intermittent compression roller 140 is further conveyed in the direction of arrow M in FIG. 3 and is cut by a cutting device 150, for example, a sheet body cutting portion (sheet body cutting). Example of process).
Specifically, for example, the disk-shaped cutter 151 (see FIG. 3) is cut by being lowered in the direction of the arrow while rotating. That is, the long wet tissue sheet group 112 conveyed on the line is cut by the cutter 151 to become the wet tissue group 20 shown in FIG. 1 corresponding to the dimensions used by the user. .

In this way, after being cut by the cutting machine 150 to form the wet tissue group 20, it is further conveyed on the line in the direction of the arrow M, and the opening label is previously arranged at the outlet 11a in the bag forming section 160 in FIG. It is stored in a moisture-impermeable storage bag 11 as shown (an example of a bag forming process).
In this way, the storage bag 11 containing the wet tissue group 20 is manufactured.

Hereinafter, the folding mechanism 120a and the like that folds the wet tissue sheet characteristic of the present embodiment will be described.
FIG. 4 is a schematic diagram showing a main configuration of the folding mechanism 120a and the like of FIG. The hatched portion in FIG. 4 is a wet tissue sheet body 111a or the like supplied from the sheet body supply roll 110a or the like, and the wet tissue sheet bodies 111a, 111c, and 111e that are used as an odd number, and the wet tissue sheet that is an even number. Only the folding positions of the sheet bodies 111b, 111d, and 111f are opposite to each other in the left-right direction. Here, the folding mechanism of the wet tissue sheet body 111a will be described.
First, as shown in FIG. 4, the folding mechanism 120a has a chemical solution impregnation unit 121 that impregnates the wet tissue sheet body 111a and the like supplied from the sheet body supply roll 110a and the like (chemical solution impregnation step). Example).
