Description

The present invention relates to a connecting structure for connecting a plurality of thick fabrics.

Conventionally, as a connecting structure for connecting a plurality of fabrics, for example, the technique described in Patent Document 1 is known. Patent Document 1 describes a cup such as a brassiere in which a plurality of cup-constituting cloths made of non-stretchable fabric are joined to each other. In this cup, highly elastic tape pieces are sewn on both the front and back sides of the joint line between the cup constituent cloths.

Jikken 4-49124 Gazette

When the tape piece is sewn on the joint line between the plurality of fabrics as described above, the thread is passed through the front and back of the fabric, and the tape piece and the fabric are bound by the thread. Then, unevenness is generated on the surface, which is aesthetically unfavorable. Further, on both sides of the joint line, a portion compressed in the thickness direction is formed, while the joint line portion maintains the original thickness. As described above, although the cup has a three-dimensional shape, the curved surface is not smoothly continuous and may be divided. When the curved surface is divided, a gap is likely to be formed inside the cup, which may affect the comfort when the brassiere is worn.

An object of the present invention is to provide a connecting structure having a three-dimensional shape suitable for covering a part of a human body and capable of suppressing division of a curved surface in the vicinity of the connecting portion.

One aspect of the present invention is a connecting structure for connecting a plurality of thick fabrics, wherein the plurality of fabrics have a first fabric and a second fabric, and the first edge portion and the second fabric of the first fabric are connected. The front surface adhesive tape and the back surface adhesive tape extending along the butt line are provided on the front surface side and the back surface side of the first fabric and the second fabric in a state where the second edge of the fabric is abutted against each other. The first fabric and the second fabric are connected by the adhesive force of the front surface adhesive tape and the back surface adhesive tape, and the butt line is curved based on the shape of the first end edge portion and the second end edge portion to form the first fabric and the second fabric. The second fabric forms a three-dimensional shape that bulges toward the front surface side or the back surface side.

According to this connecting structure, the first edge portion of the first fabric and the second edge portion of the second fabric are butted against each other, and the first fabric and the second fabric are abutted by the adhesive force of the front surface adhesive tape and the back surface adhesive tape. Are concatenated. By adjusting the shapes of the first edge portion and the second edge portion in a plan view, the first fabric and the second fabric can form a desired three-dimensional shape that bulges toward the front surface side or the back surface side. Therefore, the connecting body including the first cloth and the second cloth is suitable for covering a part of the human body. As a part of the human body, for example, a female bust or a rounded part such as an elbow, a knee, a buttocks or a head can be mentioned. Further, since the tape is not sewn with a thread or the like, the fabric is not compressed in the thickness direction. Therefore, a smooth curved surface is realized even in the vicinity of the connecting portion (that is, the butt line), and the conventional division of the curved surface is suppressed. Therefore, it is difficult for a gap to be formed on the back surface side, and it is easy to follow a part of the human body. Clothing and the like to which this connecting structure is applied are excellent in comfort. Furthermore, the surface is smooth and aesthetically pleasing.

The first edge portion of the first fabric and the second edge portion of the second fabric are the first end surface and the second end surface orthogonal to the front surface and the back surface of the fabric, respectively, and the first end surface and the second end surface are mutual. It may be in contact. In this case, since it is difficult for a gap to be formed on the front surface side or the back surface side, it is even more comfortable to wear when applied to clothing or the like. In addition, the surface becomes smooth and aesthetically pleasing.

One of the front surface adhesive tape and the back surface adhesive tape located on the convex side may be uniformly stretched in the extending direction of the butt line. In this case, the stress becomes uniform in each part of the fabric along the butt line. Therefore, the desired three-dimensional shape is surely realized without the butt line having a distorted shape.

Of the front surface adhesive tape and the back surface adhesive tape, the convex side within a predetermined section between the first position on the butt line and the second position on the butt line separated from the first position in the extending direction of the butt line. The length of one adhesive tape located on the concave side may be longer than the length of the other adhesive tape located on the concave side. In this way, by making the lengths of the adhesive tapes on the front and back sides different from each other with respect to the predetermined section, the adhesive tapes on the front and back sides can be smoothly provided without unevenness. For example, if the adhesive tape is short, the curved surface will be dented or depressed. If the adhesive tape is long, the adhesive tape will undulate. If the lengths of the adhesive tapes on the front and back are different and adjusted to appropriate lengths, the above situation can be prevented. Therefore, a stable and desired three-dimensional shape is realized.

At least one of the first fabric and the second fabric has a three-layer structure including a front side fabric and a back side fabric and an intermediate portion that is interposed between the front side fabric and the back side fabric and connects them. It may have cushioning properties. In this case, since the connecting body having a three-dimensional shape has a cushioning property, it is excellent in functional aspects such as protecting a part of the human body. In addition, the connected body has excellent skin contact.

The first dough and the second dough may have substantially the same thickness. In this case, a uniform and smooth surface is formed as the whole connecting body.

The connecting structure of the fabric of the present invention has a three-dimensional shape suitable for covering a part of the human body, and the division of the curved surface in the vicinity of the butt line is suppressed.

It is sectional drawing which cut | cut the connecting structure of FIG. 1 by the plane orthogonal to the butt line, and is sectional drawing along line III-III of FIG. It is sectional drawing which cut | cut the connecting structure of FIG. 1 on the plane including a butt line, and is sectional drawing along line IV-IV of FIG. It is a figure which shows an example of the apparatus used for manufacturing a said body. It is a perspective view which shows the connection body which concerns on the modification.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

A cup (connector) 1 according to an embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3. The cup 1 is provided on underwear such as a brassiere or upper body clothing to cover the wearer's bust. FIG. 1 illustrates a cup 1 covering the wearer's left bust. In FIG. 1, the outer shape of the brassiere is also shown by a virtual line. The cup 1 is, for example, a bowl-shaped part in which three pieces of dough are connected to each other. The cup 1 is formed to fit the wearer's bust size (cup size) in terms of shape and size. The cup 1 has a three-dimensional shape (in other words, a rounded shape) that fits the wearer's bust.

The cup 1 includes a first dough 2, a second dough 3, and a third dough 5. These fabrics have approximately equal thickness. "Approximately equal" includes the meaning that the thickness of the dough is exactly equal. "Approximately equal" means that the thickness of one dough is within the range of 0.9 to 1.1 times the thickness of the other dough. The first dough 2, the second dough 3, and the third dough 5 are, for example, the same dough. The first dough 2, the second dough 3, and the third dough 5 are made of the same material and have the same structure, for example. In addition, any one of the first dough 2, the second dough 3, and the third dough 5 may be different from the other two doughs, or all three doughs may be different.

The thickness of some or all of the plurality of fabrics may be different. Two pieces of dough with different thicknesses can also be butted and joined in the same manner as described below. By making the thickness of the dough different, the dough having a desired thickness can be arranged at a predetermined portion. For example, it is effective to make the thickness of the fabric different when it is desired to give a function such as volume up to a predetermined portion.

As the first dough 2, the second dough 3, and the third dough 5, for example, double Russell is used. The first fabric 2, the second fabric 3, and the third fabric 5 each have a three-layer structure including a front side fabric and a back side fabric, and an intermediate portion that is interposed between the front side fabric and the back side fabric and connects them. is there. For example, as shown in FIG. 3, the first fabric 2 includes a front side fabric 21 and a back side fabric 22, and an intermediate portion 23 that is interposed between the front side fabric 21 and the back side fabric 22 and connects them. .. The second fabric 3 includes a front side fabric 31 and a back side fabric 32, and an intermediate portion 33 that is interposed between the front side fabric 31 and the back side fabric 32 and connects them. Regarding the three-layer structure, the first fabric 2 will be described, and the description of the second fabric 3 will be omitted. The front side fabric 21 including the front surface 2f and the back side fabric 22 including the back surface 2g are knitted fabrics having elasticity, for example. The intermediate portion 23 is a portion knitted so as to be bridged between the front side fabric 21 and the back side fabric 22. The intermediate portion 23 has elasticity and elasticity that allows the front side fabric 21 and the back side fabric 22 to approach each other while keeping the space between the front side fabric 21 and the back side fabric 22 hollow. That is, the first fabric 2 has a cushioning property due to the three-layer structure. The first fabric 2 may have breathability.

In addition, these fabrics may be fabrics other than double Russell. These fabrics may be, for example, corrugated cardboard knit. The plurality of doughs constituting the connecting body may have a double structure or a single structure. The plurality of fabrics constituting the connecting body may be a thick non-woven fabric or the like. The plurality of doughs constituting the connecting body may have a structure of four or more layers. The plurality of fabrics constituting the connecting body may be one in which sheet-like fabrics are bonded to both sides of a non-woven fabric or both sides of a foam made of resin. The material of these fabrics may be chemical fibers, natural fibers, or a mixture of these.

The first dough 2, the second dough 3, and the third dough 5 have a predetermined thickness. The "thickness" of "having a thickness" means, for example, a thickness larger than one thread constituting the fabric. From another point of view, "having a thickness" means, for example, a thickness such that the dough can be reduced to less than half the thickness by receiving a compressive force, but returns to the original thickness when the compressive force is lost. The thickness of each of the first dough 2, the second dough 3, and the third dough 5 may be, for example, 2 mm or more and less than 20 mm.

As shown in FIGS. 2 and 3, in the cup 1, the first end surface (first end edge portion) 2a of the first dough 2 and the second end surface (second end edge portion) 3a of the second dough 3 are formed. In a state of being butted against each other, they extend along the first butt line L1 on the front surface (front surface 2f and front surface 3f) side and the back surface (back surface 2g and back surface 3g) side of the first fabric 2 and the second fabric 3, respectively. A front surface adhesive tape 11A and a back surface adhesive tape 11B are provided. Here, the butt line is a line that passes over the boundary surface (contact surface) of two fabrics having a predetermined thickness when the end faces are butted against each other. The butt line may be set, for example, in the central portion in the thickness direction.

As the front surface adhesive tape 11A and the back surface adhesive tape 11B, any type of adhesive tape may be used as long as it can exhibit adhesiveness to the fabric. The front surface adhesive tape 11A and the back surface adhesive tape 11B are the same adhesive tape, and the adhesive is applied to only one side of the base material tape. The front surface adhesive tape 11A and the back surface adhesive tape 11B are simultaneously adhered to the abutted first fabric 2 and second fabric 3 to the front surface side and the back surface side by using, for example, a connecting device 100 described later. The front surface adhesive tape 11A and the back surface adhesive tape 11B exhibit their adhesive ability by, for example, heating and pressurizing (for example, heat pressing).

As shown in FIG. 2, the shapes and lengths of the first end surface 2a of the first fabric 2 and the second end surface 3a of the second fabric 3 in a plan view are designed in advance, and based on these, the first butting is performed. The line L1 is curved. The first fabric 2 and the second fabric 3 are connected to each other by the adhesive force of the front surface adhesive tape 11A and the back surface adhesive tape 11B. Then, the first dough 2 and the second dough 3 form a three-dimensional shape that swells toward the surface side. In this way, the connection structure X of the present embodiment is formed. No thread for sewing is used in the first fabric 2 and the second fabric 3. The connecting structure X does not have a sewing portion. That is, in the connecting structure X, a plurality of fabrics are connected only by the adhesive force of the front surface adhesive tape 11A and the back surface adhesive tape 11B. The front surface adhesive tape 11A corresponds to one adhesive tape located on the convex side, and the back surface adhesive tape 11B corresponds to the other adhesive tape located on the concave surface side.

As shown in FIGS. 1 and 2, in the cup 1, the first dough 2 and the second dough 3 are first connected to form a small connecting body 4 having a connecting structure X. Further, the third dough 5 is connected to the small connecting body 4. The connection structure of the third dough 5 to the small connection body 4 is also the same connection structure X as described above.

The shapes and lengths of the upper end surface 2b of the first fabric 2 and the upper end surface 3b of the second fabric 3 and the lower end surface 5b of the third fabric 5 after connection are designed in advance, and based on these. , The second butt line L2 is curved. The small connecting body 4 and the third fabric 5 are connected to each other by the adhesive force of the front surface adhesive tape 12A and the back surface adhesive tape (not shown) provided along the second butt line L2. Then, the small connecting body 4 and the third dough 5 form a three-dimensional shape of the cup 1 that swells toward the surface side. In the relationship between the small connecting body 4 and the third fabric 5, one of them may correspond to the first fabric in the claims, and the other may correspond to the second fabric in the claims. ..

In the cup 1, the lower end surface 2c of the first dough 2, the lower end surface 3c of the second dough 3, and the central end surface 5c of the third dough 5 of the third dough 5 are smoothly continuous. The lower end surface 2c, the lower end surface 3c, and the central end surface 5c form an lower end edge 1c of the cup 1 that draws an arc-shaped (convex) curve. Further, the side end surface 3d of the second dough 3 and the side end surface 5d of the third dough 5 are smoothly continuous. The side end surface 3d and the side end surface 5d form a slightly concave side end edge 1d of the cup 1. The shape of the upper end surface 5e of the third dough 5 in a plan view corresponds to the upper end edge 1e of the cup 1 that draws an arc-shaped (convex) curve.

In these first fabrics 2, second fabrics 3, and third fabrics 5, the first end surface 2a, the upper end surface 2b, the second end surface 3a, the upper end surface 3b, and the lower end surface 5b, which are the butt surfaces, are the butt surfaces of the respective fabrics. It is an end face orthogonal to the front surface (front surface 2f, front surface 3f, and front surface 5f) and the back surface (back surface 2g, back surface 3g) (the back surface of the third fabric 5 is not shown). The first end surface 2a and the second end surface 3a, the upper end surface 2b, the upper end surface 3b, and the lower end surface 5b are in contact with each other. There is no gap between these end faces, for example, and the entire end faces are in contact with each other.

As shown in FIGS. 3 and 4, the two cloths (first cloth 2 and second cloth 3) connected by the connecting structure X have a three-dimensional shape, but the thickness thereof is the first butt line. It does not change even in the vicinity of L1 and is almost constant. Cup 1 has a smoothly continuous front and back surface as a whole. The front surface and the back surface of the cup 1 are uniform without unevenness even in the region where the adhesive tape such as the front surface adhesive tape 11A and the back surface adhesive tape 11B is provided.

The features of the connection structure X will be described in more detail with reference to FIG. In the connection structure X, between the first position P1 on the first butt line L1 and the second position P2 on the first butt line L1 separated from the first position P1 in the extending direction of the first butt line L1. A predetermined section (indicated by a broken line in the figure) can be set. This predetermined section may be set at any position and area. Within this predetermined section, the length of the front surface adhesive tape 11A is longer than the length of the back surface adhesive tape 11B. The "length of the adhesive tape" is the length when the adhesive tape is peeled off from the cup 1. This difference in length is equivalent to the difference between the length of the front surface and the length of the back surface of the fabric in a predetermined section (that is, the difference based on the difference in the radius of curvature). It is possible to identify the difference in length by removing the adhesive tape on the front and back from the actual cup product. The same can be said for the front surface adhesive tape 12A and the adhesive tape on the back surface side thereof.

The length of the surface adhesive tape 11A may be shorter than the actual length of the surface on which the tape rests, for example. The surface adhesive tape 11A is attached to the surfaces of the first fabric 2 and the second fabric 3 in a stretched state. The length of the back surface adhesive tape 11B may be shorter than the actual length of the surface on which the tape rests, for example. The back surface adhesive tape 11B is attached to the back surfaces of the first fabric 2 and the second fabric 3 in a stretched state. The length of both or one of the front surface adhesive tape 11A and the back surface adhesive tape 11B may be equal to the actual length of the surface on which the tape is placed. The length of the front adhesive tape 11A and / or the back adhesive tape 11B may be longer than the actual length of the surface on which the tape rests. When the front surface adhesive tape 11A or the back surface adhesive tape 11B is a tape made of a material that does not stretch or is hard to stretch, the front surface adhesive tape 11A or the back surface adhesive tape 11B is not stretched or is hardly stretched. And may be affixed to the surface of the second fabric 3. The same can be said for the front surface adhesive tape 12A and the adhesive tape on the back surface side thereof.

The surface adhesive tape 11A is uniformly stretched, for example, in the extending direction of the first butt line L1. That is, if five points p1 to p5 at equal intervals are marked on the bonded surface adhesive tape 11A and then the surface adhesive tape 11A is peeled off by applying heat, the marks are located at equal intervals. The surface adhesive tape 11A is peeled off by applying heat to remove the tensile stress applied in the bonded state. Since the marks after peeling are located at equal intervals, it can be seen that the surface adhesive tape 11A is evenly stretched. The same can be said for the back surface adhesive tape 11B. The same can be said for the front surface adhesive tape 12A and the adhesive tape on the back surface side thereof.

Alternatively, in the cup 1, the width of the surface adhesive tape 11A is uniform. Since the surface adhesive tape 11A is uniformly stretched as described above, the width of the tape is also uniform. The same can be said for the back surface adhesive tape 11B. The same can be said for the front surface adhesive tape 12A and the adhesive tape on the back surface side thereof.

Subsequently, the coupling device 100 for manufacturing the cup 1 will be described with reference to FIG. Each part of the apparatus described below is assembled to the base 50. The connecting device 100 includes a first roller 52 and a belt 51 arranged above the auxiliary base 40, and a second roller 54 arranged below the auxiliary base 40. An auxiliary base 40 having an upper surface extending in the horizontal direction is installed between the first roller 52 and the second roller 54. Two pieces of cloth (a piece of cloth 1'shown in the figure) and a front surface adhesive tape and a back surface adhesive tape arranged so as to sandwich the two pieces of cloth are placed on the auxiliary table 40, and the first roller 52 and the first roller 52 and the second cloth are placed. It is sandwiched between the two rollers 54.

Both the first roller 52 and the second roller 54 can rotate around an axis orthogonal to the horizontal feeding direction D, which is the feeding direction of the two fabrics, the front surface adhesive tape, and the back surface adhesive tape. The first roller 52 rotates at the same speed as the running speed of the belt 51. The belt 51 and the first roller 52 are connected to the rotation fulcrum 57 via the arm portion 57a, and can rotate around an axis parallel to the rotation axis of each roller. The belt 51 and the first roller 52 can be controlled by the elevating cylinder 56 via the rod 56a. The elevating cylinder 56 is connected to the rotation fulcrum 58 via the arm portion 58a, and can rotate around an axis parallel to the rotation axis of each roller. The position of the rotation axis of the second roller 54 is fixed.

With the above mechanism, the pressing pressure (pressing pressure) can be adjusted for the two fabrics sandwiched between the first roller 52 and the second roller 54, the front surface adhesive tape 11A, and the back surface adhesive tape 11B. ing.

The back surface adhesive tape 11B is arranged between the rollers of the first differential roller 61, on the belt 51, and on the first roller 52. The surface adhesive tape 11A is arranged between the rollers of the second differential roller 62 and over the second roller 54. The feed rates of the back surface adhesive tape 11B and the front surface adhesive tape 11A can be adjusted separately by the first differential roller 61 and the second differential roller 62.

A heater block (not shown) for heating the belt 51 and the first roller 52 is built in the inner surface side of the belt 51. A heater block 60 for heating the second roller 54 is built below the second roller 54. By controlling these heater blocks, the heating temperature for the front surface adhesive tape and the heating temperature for the back surface adhesive tape can be controlled separately.

According to the connecting device 100, the front surface adhesive tape and the back surface adhesive tape can be bonded at the same time. By performing the bonding (connecting step) on the auxiliary table 40, the tapes on the front and back sides can be bonded together with the two fabrics in a curved state, which is advantageous for forming a three-dimensional shape. One of the upper and lower sides (for example, the first roller 52 side) is the back surface side of the fabric, but the feed rate of the back surface adhesive tape by the first differential roller 61 on the back surface side is the surface adhesive tape by the second differential roller 62. It is set to be slightly smaller than the feed rate of.

Further, when the types of the front surface adhesive tape and the back surface adhesive tape are different, the upper and lower heating temperatures may be different.

In the connecting device 100 of the present embodiment, the two fabrics, the front surface adhesive tape, and the back surface adhesive tape are fed so that the butt line is located between the first roller 52 and the second roller 54. When these are hot-pressed by the second roller 54 and the first roller 52, the pressure is adjusted by the elevating cylinder 56, and the front surface adhesive tape and the back surface adhesive tape are formed in a state where the two thick fabrics maintain the thickness. It can be pasted. As a result, a connecting body such as a cup 1 having a three-dimensional shape is manufactured.

According to this connecting structure X, the first edge portion of the first fabric and the second edge portion of the second fabric are butted against each other, and the first fabric and the second fabric are abutted by the adhesive force of the front surface adhesive tape and the back surface adhesive tape. The dough is glued together. By adjusting the shapes of the first edge portion and the second edge portion in a plan view, the first fabric and the second fabric can form a desired three-dimensional shape that bulges toward the surface side. Therefore, the connecting body including the first cloth and the second cloth is suitable for covering a part of the human body. As a part of the human body, for example, a female bust or a rounded part such as an elbow, a knee, a buttocks or a head can be mentioned. Further, since the tape is not sewn with a thread or the like, the fabric is not compressed in the thickness direction. Therefore, the thickness of each fabric is maintained. A smooth curved surface is realized even in the vicinity of the connecting portion (that is, the butt line), and the conventional division of the curved surface is suppressed. Therefore, it is difficult for a gap to be formed on the back surface side, and it is easy to follow a part of the human body. Clothing and the like to which this connecting structure is applied are excellent in comfort. The brassiere to which the cup 1 is applied has an excellent fit to the bust. Furthermore, the surface is smooth and aesthetically pleasing.

Conventionally, the cross section at the position of the sewn portion and the connecting portion has a shape like a polyhedron, the curved surface is divided, and the thickness is not uniform. In the connection structure X of the present embodiment, these points are solved. Since the thickness is uniform, the occurrence of twisting due to washing is also suppressed. Furthermore, the deterioration of the touch due to the sewing thread that may occur when suture is adopted does not occur in the present embodiment.

Within a predetermined section between the first position on the butt line and the second position on the butt line that is separated from the first position in the extending direction of the butt line, the length of the surface adhesive tape located on the convex side is , It is longer than the length of the backside adhesive tape located on the concave side. By making the length of the front surface adhesive tape and the length of the back surface adhesive tape different from each other with reference to a predetermined section, the front and back adhesive tapes are smoothly provided without unevenness. For example, if the adhesive tape is short, the curved surface will be dented or depressed. If the adhesive tape is long, the adhesive tape will undulate. If the lengths of the adhesive tapes on the front and back are different and adjusted to appropriate lengths, the above situation can be prevented. Therefore, a stable and desired three-dimensional shape is realized.

The surface adhesive tape is uniformly stretched in the extending direction of the butt line. The stress becomes uniform in each part of the fabric along the butt line. Therefore, the desired three-dimensional shape is surely realized without the butt line having a distorted shape.

The first edge portion of the first fabric and the second edge portion of the second fabric are the first end surface and the second end surface orthogonal to the front surface and the back surface of the fabric, respectively, and the first end surface and the second end surface are mutual. It is in contact. With this configuration, it is difficult for gaps to be formed on the front surface side and the back surface side, so that when applied to clothing or the like, it is even more comfortable to wear. In addition, the surface becomes smooth and aesthetically pleasing.

The first fabric and the second fabric have a three-layer structure including a front-side fabric and a back-side fabric and an intermediate portion that is interposed between the front-side fabric and the back-side fabric and connects them, and the three-layer structure provides cushioning properties. Have. Since the connecting body having a three-dimensional shape has a cushioning property, it is excellent in functional aspects such as protecting a part of the human body. In addition, the connected body has excellent skin contact.

The first dough and the second dough have substantially the same thickness. A uniform and smooth surface is formed throughout the conjugate. When applied to clothing such as underwear, a connector that does not easily resonate with the outer is provided.

Further, according to the above-mentioned connecting device 100, since the feeding speed of the front surface adhesive tape and the feeding speed of the back surface adhesive tape are different, the connection structure X in the above-mentioned cup 1 can be reliably and easily produced.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the cut shape of each fabric may be changed as appropriate. A plurality of (two) butt lines may intersect as in the above embodiment, but they may be substantially parallel and do not intersect. Only one butt line may be provided.

The front surface adhesive tape and the back surface adhesive tape may be different adhesive tapes. For example, a firm tape may be used as the front surface adhesive tape, and a soft tape may be used as the back surface adhesive tape. According to this configuration, the effect of being excellent in aesthetics on the front side and being excellent in touching the skin on the skin side is achieved. Appropriate adhesive tape is placed on each of the front side and the skin side according to the purpose.

In the above embodiment, a connected body (cup as a specific example) in which three pieces of dough are connected has been described, but the present invention is not limited to this embodiment. For example, as shown in FIG. 6, the present invention may be applied to a connecting body (such as a cup) in which two pieces of dough are connected. For example, a cup 1A composed of a connecting body 4A in which a first cloth 2A and a second cloth 3A divided into left and right are connected by a front surface adhesive tape 11A and a back surface adhesive tape 11B may be provided. In this case, the butt line L1 extends from the upper end edge to the lower end edge of the cup 1A. Further, a connecting body in which four or more pieces of dough are connected may be provided. The connecting body according to these modifications also has the connecting structure X (structure described with reference to FIGS. 3 and 4) of the above-described embodiment, and the connecting device 100 of the above-described embodiment (FIG. 5). The device / connection method described with reference to) is applied.

The connecting body to which the connecting structure of the present invention is applied may cover a part other than the bust of the human body. For example, it may be incorporated into the upper body garment to cover the wearer's elbows or shoulders, or it may be incorporated into the lower body garment to cover the wearer's knees or buttocks. It may be built in or attached to a cap body or the like to cover the wearer's head.

The surface of the connecting body is not limited to a convex surface. The back surface of the connector may be convex and the front surface may be concave. In this case, the butt line is curved based on the shapes of the first edge portion and the second edge portion, and the first fabric and the second fabric form a three-dimensional shape that bulges toward the back surface side.
