Description

  The present invention relates to a method for producing a sheet-like molded body.

  The sheet-like molded body is manufactured by being processed into various shapes according to applications. For example, Patent Document 1 discloses a method of obtaining a pair of sheet members whose shapes are line symmetrical with respect to each other in succession from a single sheet material. In this method, every other line-symmetric sheet member is rotated 180 ° and transferred to a predetermined position. Thereby, the sheet | seat member of the same shape is continuously sent to the next process, and is attached to an absorptive main body so that the side panel of an absorptive article may be constituted there. By performing the same rotation, transfer, and attachment on both the left and right sides, side panels on both the left and right sides are configured, and efficient manufacturing is realized.

  In the manufacturing method described in Patent Document 1, in order to change the orientation of the sheet member, a plurality of rotatable transport heads are incorporated on the outer peripheral surface of the roll, and a device that enables rotation and transfer is provided. Yes. However, there is a limit to the degree of freedom of setting in the rotational transfer. Therefore, the rotation angle of the transport head is made constant, and the rotation of each transport head is synchronized as a series on the circumference. Therefore, a processed member is procured in a shape that meets the constraints of such processing conditions. When dealing with complex shaped sheet members or trying to cope with changes in various angles and positions, it is inevitable that the sheet members will be wasted from the original sheet, and it is difficult to improve the yield. .

It is another object of the present invention to provide a manufacturing method that can improve the yield by reducing the geometric constraints of the sheet member to be procured by improving the processing flexibility.

  The above-mentioned problem is a method for continuously manufacturing a sheet-like molded body in which two asymmetric sheet members are rotated and transferred, and two of the sheet members are symmetrically arranged on different sheet materials. The sheet member cutting step of cutting the member substantially continuously in the front-rear direction from the original sheet so that the member is a set of four members on the front, rear, left, and right in the initial arrangement so as to be symmetrical about the left and right and have the same shape on the front and rear, A pair of sheet members are gripped by the transfer means and rotated, the two diagonally positioned are placed on the left and right at positions shifted in the conveying direction, and the remaining two diagonally positioned sheet members are The invention has been solved by a method of manufacturing a sheet-like molded body having a rotational transfer step of further rotating the shaft by the transfer means and placing the two previously placed sheet members side by side.

  According to the manufacturing method of the present invention, it is possible to perform a rotational transfer process with a high degree of freedom without relying on a complicated mechanism in the manufacture of a sheet-like molded body that rotates and transfers a sheet member. In addition, the improvement in the processing freedom described above can reduce the shape constraints of the sheet member to be procured and improve the yield.

The manufacturing process of the sheet-shaped molded body of the present embodiment includes, as a whole, a process (I) for cutting the first sheet material, a process (II) for rotating and transferring the first sheet member, and a sheet-shaped composite. It consists of a step (III), a step (IV) for producing a sheet-like intermediate, a step (V) for transferring the sheet-like intermediate, and a step (VI) for cutting the third sheet original fabric. In addition, the position corresponding to each of process (I)-(VI) was shown in FIG. 1 by the number.

-Cutting the first sheet material (I)
In (I) of FIG. 1, the first sheet material 1 fed from the roll 61 and conveyed along the conveying path is cut into a first sheet member having a predetermined shape by a cutting machine 91. A die-set type punching device can be applied to the cutting machine 91. For example, a device using a Thomson blade or an equivalent device can be used. In addition, the cutting device (rotary die cutter) provided with the die cut roll can also be used.
In order to supply the 1st sheet original fabric 1 to process (I), in this embodiment, a conveyance path should just comprise a winding roller, a drive roller, a belt conveyor, a vacuum conveyor, a roller conveyor, etc. in combination. The conveying means conventionally used for conveying the sheet member can be appropriately selected and used. Further, in the present embodiment, the first sheet raw fabric 1 is automatically and stably not restricted by the outer diameter of the state wound around the roll 61, the deformation from the perfect circle, and the change in the surface state. It is preferable to provide an automatic paper guiding device capable of feeding and guiding paper. The same applies to an apparatus for feeding out the second sheet original fabric 2, the third sheet original fabric 3, the first ventilation material original fabric 5, and the second ventilation material original fabric 4.

  In the present embodiment, the first sheet member is continuously cut from the first sheet raw fabric 1 as the first sheet members 1a to 1d having a predetermined shape shown in FIG. As shown in FIG. 2A, each first sheet member is formed in the same shape in the transport direction (MD direction) and is formed in a line-symmetric shape in a direction (CD direction) perpendicular to the first shape. Further, similar first sheet members 1a to 1d are sequentially cut in the transport direction.

  In the present embodiment, illustration is omitted, but without shifting the first sheet member cut as described above during the transition from the step (I) to the next step (II). The arrangement is changed to diffuse in the transport direction (MD direction) and the direction perpendicular to the transport direction (CD direction). This is an arrangement change from step (a) to step (b) shown in FIG. The first sheet member is assumed to be heating sheets 1a to 1d (see FIG. 4A) such as a papermaking thermal sheet. Taking the first sheet member 1a as an example, the first ventilation member 5a and the second ventilation member 4a are arranged on the front and back, and the second sheet member 2a is further arranged. Complex) 1A is constructed. Four sheet-like intermediate bodies 1A to 1D having the same form are arranged in four directions to form a set of four (see FIG. 4B). Note that MD (direction) is the above-described transport direction and is an abbreviation for “Machine Direction”. Also called flow direction. CD (direction) is a direction orthogonal to the MD and is an abbreviation of “Cross Direction”.

・ Rotary transfer of the first sheet member (II)
In FIG. 1 (II), the first ventilating material 5 on which the first sheet member is placed is unwound from the wound roll 65, conveyed along the conveying path, and then conveyed horizontally at a predetermined position. Is done. A plurality of first sheet members obtained in the previous process are held by the transfer means 92 at a position slightly apart from the horizontally conveyed position, changed to a desired orientation, and are conveyed horizontally. 1 It is transferred onto the original material 5 of the ventilation material. This transfer is performed continuously, and the first sheet members are arranged in a predetermined direction on the first ventilation material original fabric 5. Details of the transfer will be described later.

  At the position where the transfer means 92 holds the first sheet member and the position where the held first sheet member is placed on the first ventilation material original fabric 5, the first sheet member and the first ventilation material original fabric respectively. 5 is conveyed horizontally by a known rotary drive belt. The tension and the like are determined in consideration of the mass of the first sheet member placed on the belt without bending. In this position (II), it is preferable to control the stop, start timing, speed, and alignment of the operation of conveying the first sheet member or the first ventilation material original 5 in synchronization with the operation of the transfer means 92. As described above, as means for gripping the first sheet member or the first ventilation material original fabric 5, for example, sequencer control using a servo motor or an equivalent control method can be used, but is not limited thereto.

  In the present embodiment, the transfer means 92 has a robot mechanism that can move in the transport direction (MD direction) or a direction orthogonal to the transfer direction (CD direction), and that can perform a rotational operation with one or more axes. A vacuum unit that sucks and fixes the sheet member, a mechanical hand that mechanically grips the sheet member, and the like can be adopted as the portion that grips the sheet member. Further, in order to control the direction of the first sheet member, a visual sensor using a video camera or the like may be used to control the driving of the robot mechanism. Examples of the robot mechanism to be used include those having a drive motor and a drive transmission system configured to move the robot hand in the horizontal direction. Further, another drive motor and another drive transmission system configured to move the robot hand up and down in the vertical direction and rotate in the rotation direction with respect to the first sheet members arranged in the horizontal direction. Is mentioned.

  If necessary, a mass meter may be provided near the transfer means 92 and each mass may be inspected by replacing the held first sheet member with the mass meter one after another. Further, the shape and color can be inspected using a visual sensor using a video camera or the like. Considering the use as the eye thermal mask, it is preferable to accurately grasp and manage the temperature of the first sheet member constituting the thermal sheet member from the viewpoint of stabilization of the performance.

・ Process for producing sheet composite (III)
The 2nd ventilation material original fabric 4 is drawn | fed out from the roll 64 currently wound, and is conveyed along a conveyance path. Thereafter, the second sheet original fabric 2 fed out from the wound roll 62 is joined to the second ventilation material original fabric 4, and the laminated second ventilation material original 4 and second sheet original fabric 2 As described above, the first sheet member 5 is transported by being overlapped from above so as to sandwich the first sheet member with respect to the first ventilator raw fabric 5 which is transported horizontally with the first sheet member placed thereon. In this horizontally conveyed position, the bonding machine 93 causes the first ventilation material original fabric 5, the second ventilation material original fabric 4, and the second sheet original fabric 2 to surround the first sheet member, such as hot melt. These are bonded by an adhesive, heat seal, ultrasonic seal or the like to produce a sheet-like composite. If necessary, the first sheet member sandwiched between them is also joined by an adhesive such as hot melt, heat sealing, ultrasonic sealing or the like. The 2nd sheet original fabric 2 is arrange | positioned outside the 2nd ventilation material original fabric 4 in a sheet-like composite.

・ Process for producing sheet-like intermediate (IV)
Subsequently, the cutting machine 94 cuts the outer side of the joined portion obtained by joining the outer periphery of the first sheet member so as to have an L shape larger than the outer periphery of the first sheet member. Thereby, the sheet-like intermediate body which has the 1st sheet | seat member enclosed by this junction part and included in the 1st permeable material member, the 2nd permeable material member, and the 2nd sheet | seat member is obtained. These sheet-like intermediate bodies 1A to 1D are steam thermal composites in the present embodiment (see FIG. 4B). The outlines of the four sheet-like intermediate bodies 1A to 1D obtained here are all the same.

-Step of transferring the sheet-like intermediate (V)
In FIG. 1 (V), the 3rd sheet original fabric 3 which mounts a sheet-like intermediate body is unwound from the roll 63 wound, is conveyed along a conveyance path, and is conveyed horizontally in a predetermined position. The The sheet-like intermediate bodies 1 </ b> A to 1 </ b> D obtained by cutting in the above-described process are transferred to the third sheet original fabric 3 in a horizontal state by the transfer means 95. At this time, among the four sheet-like intermediate bodies 1A to 1D, the front left and right two sheet-like intermediate bodies 1B and 1D are not moved, and the third sheet original fabric is not opened between the left and right sides. 3 is arranged. Further, in the present embodiment, the transfer means 95 is used to change the arrangement of the left and right two sheet-like intermediate bodies 1A and 1C to be interchanged, and the sheet-like intermediate bodies 1B and 1D are spaced apart from each other. Arrangement on the third sheet material 3 is performed without a gap. For these operations, for example, an apparatus having the same mechanism as the transfer means 92 described above can be used. However, since the transfer operation here is only movement and left / right replacement, a device with a more simplified mechanism can be applied. The third sheet original fabric 3 and the sheet-like intermediates 1A to 1D are joined by a bonding machine (not shown) by an adhesive such as hot melt, heat sealing, ultrasonic sealing or the like.

  Speaking of important advantages in the present embodiment, the direction of the fibers of the second sheet member 2 on the second ventilation member 4 (for each sheet-like intermediate body 1A to 1D joined to the third sheet raw fabric 3 ( The fiber orientation direction) is the same in the transport direction (MD direction). As described above, in the transfer when placing on the third original sheet 3, the sheet-like intermediates 1A and 1C whose positional relationships have been changed only perform the arrangement change to replace the positions in the CD direction. ing. Therefore, there is no position change that changes the direction from the MD direction to the CD direction by 90 °. Therefore, in the eye thermal mask 10 (10A, 10B) finally manufactured in the present embodiment (see FIG. 4C), the product has not only the shape of the member but also the direction of the fibers of the member. be able to. In particular, since the eye heat mask is used against the human face, it may affect the feeling of wearing and the steam heat effect, so it is particularly effective to align the eyes of the fibers as described above. .

・ Process of cutting the 3rd sheet material (VI)
In (VI) of FIG. 1, in a state where the third sheet original fabric 3 and the sheet-like intermediate are joined and conveyed, the cutting machine 96 cuts with an arbitrary outline wider than the outline of the sheet-like intermediate, A sheet-like molded body 10 is obtained. In this embodiment, two sheet-like intermediate bodies are joined to the sheet-like molded body 10, and the obtained sheet-like molded body 10 is an eye thermal mask 10 (10A, 10B) (FIG. 4). (See (c)). Therefore, normally, the contour for cutting the third sheet original fabric 3 is the contour of the product, and if a hole or a cut is necessary as the product, they are formed simultaneously. The obtained sheet-like molded body 10 is transferred to a belt conveyor or the like (not shown), and is conveyed, for example, to a bag storing step. Furthermore, other necessary sheet members and the like may be stacked and joined to continuously manufacture a sheet-like molded body. As the cutting machine 96, the same ones as the cutting machines 91 and 94 in step (I) can be used.

[Shape, transfer and rotation of first sheet member]
In the manufacturing method of the sheet-like molded body of the present invention, the details of the embodiment in the rotation and transfer will be described with reference to FIG. 2 for the step (II) of rotating and transferring the first sheet member. The shape of the first sheet member will also be described based on FIG. The first sheet members 1a to 1d shown in the figure correspond to the first sheet member described with reference to FIG. For easy understanding, the first sheet member 1c and 1b shown in black are marked with a circle on the slightly cranked side of the first sheet member.

  In one embodiment of the method for producing a sheet-like molded body of the present invention, as shown in FIG. 2 (a), the first sheet members 1a, 1b, 1c, 1d are arranged in the front-rear direction from the first sheet original fabric. It is cut out substantially continuously. In the present invention, “substantially continuously cut out” means that the shape of each member is determined in consideration of the manufacturing condition restrictions in the rotational transfer process, and is not cut out leaving a large surplus portion. To do. Therefore, this means that there is a gap between the members for another reason. From the viewpoint of improving the yield, it is preferable to continuously cut without a gap.

  Each of the first sheet members 1a, 1b, 1c, and 1d has an asymmetric shape (non-symmetrical and non-point-symmetric), and preferably has a crank shape as a whole. Not symmetric. Further, in the present embodiment, the first sheet members 1a to 1d are arranged in a symmetrical manner in the left and right and in the same shape in the front and rear in the initial arrangement in which the first sheet member 1a to 1d is cut out from the first sheet raw fabric 1. It is arranged to be. That is, when the first sheet members 1a and 1d are rotated symmetrically about the center line c (not shown), the first sheet members 1c and 1b overlap each other. On the other hand, when the rear first sheet members 1a and 1c are fed forward, the front first sheet members 1d and 1b are overlapped. In the description here, the direction of proceeding to steps (a) to (e) in FIG. 2, that is, the transport direction is set to the front and the reverse (MD direction), and the direction perpendicular to this is set to the left and right (CD direction). As described. Also, the front in the transport direction may be referred to as downstream and the rear as upstream. The center line c is a center line in the width direction of the first original sheet 1, but may be any line that separates the first sheet members 1a, 1d and the first sheet members 1c, 1b. The center of the original sheet 1 may not be the exact center in the width direction (CD direction).

  Thereafter, the pair of first sheet members 1a to 1d shown in FIG. 2 (a) is gripped by a gripping tool (not shown) installed on the transfer means 92, and each interval between the gripping tools is widened. Then, as shown in FIG. 2B, the first sheet members 1a to 1d are separated from each other in the direction away from the center line c and in the front-rear direction.

  Next, as shown in FIG. 2C, the transfer means 92 is rotated by 90 °. Then, the two first sheet members 1a and 1b positioned diagonally rotated in this manner are placed on the first air-permeable material 5 (see FIG. 1) being conveyed. In FIG. 2C to FIG. 2E, the first ventilation material original fabric 5 is not shown for simplification of description.

  The remaining two first sheet members 1c and 1d do not release the gripped state and are further rotated 180 ° in the same direction or in the opposite direction. The first sheet members 1c and 1d positioned at the two remaining diagonal positions after the rotation are placed on the first sheet material 5. Then, as shown in FIG. 2D, the first sheet members 1c, 1d are arranged on the left and right sides of the two loaded first sheet members 1a, 1b, respectively. Placed on top.

  In the present embodiment, an arrangement change is performed in which the left and right of the first sheet members 1a and 1b located further rearward are exchanged. In the embodiment shown in FIG. 1, this is a process performed on the sheet-like intermediate body. However, in order to simplify the description, the arrangement of the first sheet member is described as it is. By changing the left and right arrangements in this way, the left and right two first sheet members or the sheet-like intermediate body including the first and second sheet members are made symmetrical in the front and rear directions, and are arranged so as to coincide with each other by rotating the shaft. . Therefore, as described above, when the final product is as shown in FIG. 4C, a large number of products having the same shape can be continuously produced in the process flow direction (MD direction).

  In the present embodiment, the rotation and transfer of the first sheet member or the sheet-like intermediate body including the first sheet member are completed as described above. That is, in the method for manufacturing a sheet-like molded body according to the present embodiment, four first sheet members are simultaneously handled twice in order to continuously obtain a final product having the same shape by combining two asymmetric sheet members. Since it can be configured by only the rotational transfer operation and the left and right arrangement change only once, it is extremely effective in simplifying the equipment. Furthermore, it is possible to obtain the first sheet member continuously without gaps in the front-rear and left-right directions, and waste generated in the material can be greatly reduced.

Next, a modification of the rotational transfer process will be described with reference to FIG. As shown in the figure, the first set of first sheet members 1a ₁ , 1b ₁ , 1c ₁ , 1d ₁ , and the second set of first sheet members 1a ₂ that are continuously cut from the first sheet raw fabric ₁ . 1b ₂ , 1c ₂ , 1d ₂ , and a third set of first sheet members 1a ₃ , 1b ₃ , 1c ₃ , 1d ₃ are shown to be transferred onto the first ventilation material original fabric 5 in this order. ing. In the actual manufacturing process, a large number of first sheet members are continuously carried out. By sequentially performing these three sets of operations, the rotational transfer of the members can be continued continuously.

In the illustrated example, the first set of first sheet members 1a ₁ , 1b ₁ , 1c ₁ , 1d ₁ cut from the first sheet original fabric 1 shown in FIG. 3 (a) is shown in FIG. 3 (b). As described above, the two first sheet members 1b ₁ , 1d ₁ and the two first sheet members 1a ₁ , 1c ₁ are rotated away from each other in the front-rear direction and transferred onto the first ventilation material original fabric 5. It is listed. This process is the same as the process of FIGS. 2 (a) to 2 (d). The gripped first sheet members 1a ₁ , 1b ₁ , 1c ₁ , 1d ₁ are rotated by 90 degrees and the diagonally positioned first sheet members 1a ₁ , 1b ₁ are placed on the first air-permeable material 5. The first sheet members 1c ₁ and 1d ₁ that are positioned and positioned diagonally while being held are further rotated 180 degrees and placed on the first ventilation material original fabric 5. The distance separating the first sheet member 1b ₁ , 1d ₁ and the two first sheet members 1a ₁ , 1c ₁ in the front-rear direction is a distance that allows the two first sheet members to be accommodated in the transport direction (MD direction). The That is, in FIG. 3C, the left and right pairs of the first sheet members that have been placed first (shown by dashed lines) and the left and right sides of the second set of first sheet members 1 b ₂ and 1 d ₂ . One pair is set as an interval between them. That is, when the first sheet member shown in FIG. 2B is separated, the first sheet member is separated so as to be approximately every two in the MD direction which is the front-rear direction. The first ventilating material 5 is intermittently transported, is stopped during the placement of the first set of first sheet members, and is advanced by a predetermined distance before the placement of the second set of first sheet members. It is preferable to leave.

Then, the rotation and transfer operation, performed for the second set of the first sheet member _{1a 2,} 1b _2, 1c two, 1d _2. By the above rotation and transfer operations, as shown in FIG. 3C, the second set of first sheet members 1b ₂ , 1d ₂ is moved in the conveying direction of the first set of first sheet members 1a ₁ , 1c ₁ . Placed downstream and upstream of the left and right pair of first sheet members indicated by the one-dot chain line already placed, and placed in a place where the second set of first sheet members 1a ₂ and 1c ₂ are separated. To do.
Further, the above-described rotation and transfer operations are similarly performed on the third set of first sheet members 1a ₃ , 1b ₃ , 1c ₃ , 1d ₃ . As shown in FIG. 3D, the third set of first sheet members 1b ₃ , 1d ₃ is replaced with the first set of first sheet members 1a ₁ , 1c ₁ and the second set of first sheet members 1a ₂ , 1c. ₂ and placed in a place where the third set of first sheet members 1a ₃ and 1c ₃ are separated.

  As a result, the three sets of the first sheet members can be rotationally transferred and arranged at desired positions. Further, the first sheet member arranged in this manner is separated as viewed in the MD direction, and if necessary, the operation of changing the left and right positions is performed as shown in FIG. The first sheet member having the final arrangement is continuously obtained.

  By continuously rotating and transferring the first sheet member in the front and rear of one group and separating a part of the first sheet member in the next group between them as in the modification, FIG. As shown in (b), the paper-making thermal composites (sheet-like intermediate bodies) 1A to 1D composed of the first sheet member, the first ventilation member 5, the second ventilation member 4, and the second sheet member are continuous as much as possible. Thus, it is possible to arrange the first ventilation member 5 and the second ventilation member 4 as much as possible.

[Manufacture of eye thermal mask]

[material]
The first sheet member can be used in various applications as a sheet-like product for steam-heating the obtained sheet-like molded body by using a papermaking thermal sheet. In addition, when making a 1st sheet | seat member into a papermaking thermal sheet | seat, it is preferable to implement in the apparatus assembled in the inert gas atmosphere. As the papermaking thermal sheet, those described in JP-A-2003-102761 can be used.

The 1st ventilation material member 5 and the 2nd ventilation material member 4 can be comprised from a moisture-permeable film or an air-permeable film. The moisture-permeable film is manufactured by forming a melt obtained by melting and kneading a thermoplastic resin and an inorganic filler into a film shape, and uniaxially or biaxially stretching the formed film. Moisture permeability (JIS Z0208,40 ℃, RH 90% ) of the moisture-permeable ^{film, 200~5000g / (m 2 · 24hr} ), particularly preferably a ^{500~1000g / (m 2 · 24hr)} , moisture permeability (Defined by JIS Z0208) and air permeability (specified by JIS P8117) are appropriately selected depending on the composition and amount of the papermaking thermal sheet and the usage form. In order to improve the touch of the product, a sheet member having a good texture such as a nonwoven fabric may be laminated on the outer surface of the moisture-permeable film. The thickness is appropriately determined in consideration of the thickness and mass of the first sheet member sandwiched therebetween. Moreover, it is preferable that the size surrounds the outline with a width of about 0.5 to 5 mm from the first sheet member.

As the 2nd sheet member 2 and the 3rd sheet member 3, a nonwoven fabric, a woven fabric, gauze, paper, a net-like body, felt, etc. can be used. In order to make the obtained sheet-like molded body into a sheet-like product that is heated by steam, as in the eye heating mask that is one embodiment described above, a nonwoven fabric is particularly suitable. As the nonwoven fabric, a nonwoven fabric having a low basis weight, for example, a nonwoven fabric having a basis weight of 20 to 200 g / m ^{2, and} a nonwoven fabric having a basis weight of 50 to 150 g / m ² is preferable. As the nonwoven fabric, various known nonwoven fabrics can be used, and examples thereof include an air-through nonwoven fabric, an airlaid nonwoven fabric, a spunlace nonwoven fabric, a spunbond nonwoven fabric, and a needle punched nonwoven fabric. The thickness is appropriately determined in consideration of the thickness and mass of the sheet-like intermediate body to be fixed. However, the thicker one as compared with the first air-permeable material raw material and the coated sheet raw material has less unevenness as a whole. It is preferable. In particular, the third sheet member is preferably stretchable.

  The manufacturing method of the sheet-like molded object of this invention is not restrict | limited to the above-mentioned embodiment at all, and can be suitably changed in the range which does not impair the meaning of this invention. For example, the order of the step (VI) for cutting the above-described third sheet raw material and the step (V) for transferring the sheet-like intermediate is changed, and the third sheet member 3 is cut into a mask shape first, Two sheet-like intermediates may be transferred there.

  Moreover, the manufacturing method of the sheet-like molded object of this invention is applicable to various sheet-like molded objects without the restriction | limiting in particular including the embodiment illustrated for description. In particular, it is preferable to apply to products that require a degree of freedom in the rotational transfer process. As a sheet-like molded object manufactured, for example, it can be widely used as a product such as cosmetics, medical supplies, daily necessities, or a part of these products.

  As described above, in the illustrated embodiment, after the two shafts rotate, the two papermaking thermal composites 1A and 1C are rearranged on the left and right sides in the step (V), and are arranged symmetrically in the front, rear, left and right. . On the other hand, although not shown in the figure, as another embodiment, the transfer of the step (V), that is, the left and right of the two papermaking thermal composites 1A and 1C are not replaced, and the front and rear are arranged in line symmetry only on the left and right. It may be a non-axisymmetric product form (final arrangement). For example, the papermaking thermal composites 1A and 1C that are not interchanged on the left and right can be provided for a person with a small face size or for a chin. In the case of the chin, the third sheet member has a pair of holes for hooking the ears, but an opening or a recess corresponding to the position of the mouth instead of the pair of holes at the positions of the left and right eyes Is provided.

-Shape of the first sheet member In the illustrated embodiment of the present invention, the four first sheet members 1a, 1b, 1c, and 1d have the same shape in the front and rear and are mirror images on the left and right. One sheet member 1a, 1b, 1c, 1d is rotated at the same angle and can be turned. In such a case, the present invention is suitable, and the two sheet-like molded bodies obtained are exactly the same.
However, for example, if the first sheet member 1a and the first sheet member 1d are not the same shape, the first sheet member 1b and the first sheet member 1c are not the same shape, or both have different shapes, The two sheet-like molded bodies obtained are different from each other, and each has a shape that is not symmetrical with respect to the left-right line. Therefore, changing the contours or changing the arrangement of the four first sheet members 1a, 1b, 1c, and 1d in this way is suitable when two different sheet-like molded bodies are manufactured simultaneously as one set. It is.

  As shown in FIG. 2, the first sheet member is rotationally transferred with respect to the first air-permeable material original, and the first sheet member is arranged and joined to the first air-permeable material original 5, so that the second sheet member 2 is attached. The 2nd ventilation material original fabric 4 which has not laminated | stacked is laminated | stacked on it, and is the same as the shape of the 3rd sheet | seat member 3 shown in FIG.4 (c), and the 1st ventilation material original fabric 5 and the 2nd ventilation material original fabric are the same. 4 may be joined and cut to produce the eye thermal mask 10. In this eye thermal mask 10, the entire shape of the mask is constituted by the first ventilation member 4 and the second ventilation member 5, and the second sheet member 2 and the third sheet member 3 are not provided.
