DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of sewing patchwork, and more particularly to a method of ending the edge of a piece of cloth to be patchworked.

[0005]

2. Description of the Related Art In conventional patchwork, an overlock (edge overlock sewing) or end sewing machine is used to prevent a seam allowance from playing at the time of washing or use and to prevent fraying. In a traditional patchwork quilt, apply a separate cloth to the sewing surface of the cloth piece so as not to show the seam allowance on the back side, and furthermore, put both sides vertically and horizontally to prevent the gap between the cloth and the back cloth and to prevent the cloth piece from fraying It is common practice to perform quilting, which is a method of suturing, or to overlap and sandwich a quilt core (such as cotton) therebetween.

[0006] As a method of sewing the cloth pieces so as not to expose the seam allowance, two cloth pieces are overlapped with their edges aligned and sewn along the edges. A sewing margin setting method has been proposed in which the fabric edge of the sewing margin is not exposed to the outer surface. (Japanese Patent Publication No. 6-102117)

[0007] Further, the present invention relates to a patchwork in which various cloth-made works are connected by a cloth cloth as a patchwork.
It has been proposed that the back side of a joining edge of a plurality of works is pasted on an elastic cloth cloth to form a patchwork in which the works are joined together without any gaps, so that the work can be easily and beautifully joined. (62-7
No. 9897)

[0008]

In the conventional patchwork, the seam allowance such as overlocking and end sewing is not suitable for use because the seam allowance which is inferior and runs in all directions is inferior and the back is never seen. Limited to

The quilting process using a different cloth so as not to show the seam allowance on the back of a traditional patchwork quilt, and the quilting process using a quilt core (such as cotton) take an enormous amount of time. Processing techniques require a great deal of skill. In addition, plain woven cotton is often used as a material from the historical background since the era when the cloth was valuable so that the quilting line can be beautifully put out, and the quilting process requires more time and skill to compensate for the lack of luxury Had to be applied. In the prior art (Japanese Patent Publication No. 6-102117), a method of dividing the seam allowance and wrapping it with a bias is very troublesome in patchwork in which small pieces of cloth are sewn together. The overlapping part is folded in three and the thickness increases, which is not suitable for patchwork in which a large number of cloth pieces are sewn together. In addition,
In Japanese Patent Application Laid-Open No. 7-107, the gap between the fitted cloth pieces is not opened, and it is more like the removal of the applique by the zigzag sewing machine than the removal of the sewing allowance of the patchwork. The present invention makes it possible to design patchwork without worrying about the seam allowance, can use the kind of cloth that can be seen through from ultra-thin to bulky and extremely thick, greatly expand the width of the material, select the cloth according to the purpose of use, and sew The purpose is to expand the range of applications. It is an object of the present invention to increase the value of high-grade interior and high-end miscellaneous goods in a reduced time without requiring skill by being able to use ultra-thin material such as lace and silk from ultra-thin material such as silk. It is in.

[0010]

In order to solve the above-mentioned problems, according to the present invention, the edges of two pieces of cloth are aligned and overlapped, and the edge of the ribbon lace is placed on one side of this piece of cloth. The primary seam is sewn in the opposite direction to the lace side so as to cover the seam allowance with the ribbon lace, and then the edges of the seam allowance are separated by a predetermined width from the primary seam. It is at the point of the next suture.

[0011] In a second configuration, three pieces of cloth, which are overlapped with a ribbon lace sandwiched between two pieces of cloth, are firstly sewn, and the seam allowance is lowered so that the respective seam allowances on both sides are covered with the ribbon lace. , At the point where the edges of the seam allowance are respectively secondary sewn with a predetermined width from the primary suturing.

Further, in the structure according to the third aspect, the edges of the two cloth pieces are aligned and overlapped, and the edges of the ribbon lace are aligned and overlapped on one side of the cloth pieces.
Take the required seam allowance width and perform primary stitching, and after sloping opposite to the lace side so as to cover the seam allowance with the ribbon lace, secondarily sew the edge of the seam allowance with a predetermined width from the primary seam, and / or The three pieces superimposed with the ribbon lace sandwiched between two pieces of cloth are firstly sewn, and the seam allowances fall down so that the respective seam allowances on both sides are covered with the ribbon lace. The present invention consists in repeatedly performing secondary suturing on the edges to sew a plurality of pieces of cloth to form a patchwork cloth finished into a large cloth.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. First, as shown in FIG. 1, the edges of the cloth pieces 1 and 2 are aligned to form a so-called middle surface state in which the surfaces are overlapped with each other,
A ribbon lace R3 is placed on one of the back surfaces of the cloth pieces 1 and 2 so that the back surface of the cloth piece and the back surface of the ribbon lace are joined to each other so as to be in the middle back state. Next, as shown in FIG. 2, a required sewing margin width A is provided, and the cloth pieces 1, 2 and the ribbon race R3 are simultaneously moved to the primary stitching line L1.
Suture along. As shown in FIG. 3, the cloth piece 2 is opened and one cloth piece is turned over (one-sided) so that the ribbon lace R3 covers the sewing allowance when viewed from the sewing surface of the ribbon lace. Furthermore, as shown in FIG. 4, the cloth pieces 1 and 2 and the edges of the seam allowance of the ribbon lace R3 sewn and aligned on the cloth pieces 1 and 2,
In other words, a required sewing margin width B is further provided from the cloth end (cutting end), and the cloth piece 2 is stitched along the secondary stitching line L2. That is, as shown in FIG. 4, the stitching is performed when viewed from the sewing surface of the ribbon race R3. Thus, the suture line L
By suturing at the positions of L1 and L2, the strength at the seam allowance is increased and the cut edge of the piece of cloth can be prevented from fraying.

Further, when the primary suturing L1 and the secondary suturing L2 are to be performed, the alignment of the ribbon lace R3 is made to protrude outside the edges of the cloth pieces 1 and 2, and the other cloth pieces 1 and 2 are arranged.
If you select the width of the ribbon lace used so that it will protrude beyond the edge of the seam allowance, that is, the outer edge of the fabric (cut edge), the color and pattern of the ribbon lace R3 will be emphasized, and the decorative effect will be improved. .

Next, a second embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 5, two laces 3 and 4 are placed on the front side, and only the seam margins are butted from both sides. As shown in FIG. It is sandwiched between the cloth pieces 3 and 4 so as to be in a state. At that time, first, the ribbon race R5
The primary suture line L of the cloth piece 3 in consideration of the overall design.
3 determines the protrusion width C of the ribbon lace R5 seen from the cloth piece 3 side. The sewing margin width of each of the cloth pieces 3 and 4 is set so that the ribbon lace R5 protrudes, the primary sewing line L3 on the ribbon lace 5R is determined, and the cloth pieces 3 and 4 and the ribbon lace R5 are determined. And suturing at the same time. Next, as shown in FIG. 6, the seam allowance protruding on the cloth piece 3 side and the seam allowance protruding on the other cloth piece 4 side are reversed (one-sided) so that each is covered with the ribbon lace R5. The edge of the ribbon race R5 is sewn to the cloth pieces 3 and 4 along the next sewn lines L4 and L5. That is, the ribbon race R5 is in a state of being stitched to the cloth pieces 3 and 4. As a result of the secondary stitching as described above, the seam allowance can be further thinned by dividing the seam allowance.

Making full use of the two sewing methods described above,
You can see through the ribbon lace, make it visible directly, and sew multiple pieces of cloth vertically and horizontally using various materials from ultra-thin material such as lace to extra-heavy material such as high-grade fabric. It is possible to obtain a patchwork fabric with a variety of designs by taking into account the decorative effects such as colors and patterns.

[0017]

The present invention is configured as described above,
When two pieces of cloth are sewn together with a ribbon lace to finish the sewing allowance, the seam allowance is fixed, so that the two pieces can be used in one sheet without being frayed or exposed. The use of ribbon lace, taking advantage of the effects of see-through, combined with multiple pieces of patchwork in color and type, plays a major role as a new item in patchwork design.

When the color and shape of the ribbon lace can be seen through from the back and when one of the laces can be seen directly at the time of sewing, the type of material that can be used is increased by finishing the seam allowance more thinly. By combining these two sewing methods, the range of patchwork design is expanded,
This makes it possible to sew a variety of patchwork fabrics combined with ultra-thin and ultra-thin fabrics of completely different materials, such as lace and luxury fabrics, and that fabric is used as a material for luxury interiors and luxury goods. High utility value.
