EXAMPLE A method for manufacturing a two-layered futon according to an example of the present invention will be described with reference to FIGS. First, the configuration of the futon manufactured by the method of the present example will be described first with reference to FIGS.

This futon has side edges at both ends in the width direction of a lower cloth group (first cloth group) 10 and an upper cloth group (second cloth group) 20 which are formed in a substantially rectangular shape. 10
a. 20a are connected to each other by a tape-shaped gusset cloth 30 (see FIG. 5), and side edges 10b.
b It is configured to be directly sewn together (without interposing a gusset cloth).

The lower cloth group 10 is sewn at the periphery to form a bag, and the upper and lower side grounds are sewn together along the longitudinal direction to form four quiltings 11. This prevents movement of the batting 12. As the material of the upper and lower laterals in the lower cloth group,
Satin land is used.

The upper cloth group 20 is sewn at its periphery to form a bag, and further, as shown in FIG. 2, a double quilting 21a having a substantially rectangular shape is provided near the center thereof. Four quiltings 21b in the width direction are provided inside the quilting 21a. Each of these quiltings 21 is configured by so-called zigzag stitching (a sewing method that imparts elasticity to the cloth by sewing in zigzag). In addition, the side fabric that constitutes the overcloth group 20 is composed of a stretchable knit fabric. The batting 22 of the upper cloth group 20 is formed by laminating polyester hard cotton 22a, wool hard cotton (cotton whose elasticity is reduced by needle processing) 22b, and wool forming cotton 22c in this order from the upper part in FIG.

As the material of the gusset cloth 30, in the present embodiment, a flocked cloth having flocked on the outer surface side is used.

Next, an embodiment of the method for manufacturing the futon according to this embodiment will be described with reference to FIGS. First, as shown in FIG. 6, the futon material 40 that will be the lower cloth group 10 is continuously sewn, and at the same time as this sewing operation, the long gusset cloth 30 is sewn to the side edge of the futon material 40. This work
This can be easily carried out continuously by accommodating the batting between the long side fabrics and stitching them with a multi-head sewing machine with the gusset cloth arranged on the side edges of the side fabrics. Also,
In this sewing operation, the quilting 11 is simultaneously performed by the multi-head sewing machine. Then, the long futon material 40 is cut into a predetermined length (about 2 m), the cut ends are sewn together, and the batting 12 is enclosed inside the futon.
0 is produced. The width of the futon material 40 is the same as the width of the lower cloth group 10.

On the other hand, in the case of the upper cloth group 20, the batting 22 is housed between the side fabrics made of knit which are preliminarily cut into a rectangle, and the side edges are sewn together to enclose the batting 22.
It is manufactured by quilting 21a and 21b. The sewn work of the quilting 21a, 21b can be performed by a so-called comforter. Further, the upper cloth group 20 has substantially the same shape as the lower cloth group 10 produced by cutting as described above.

Then, the upper and lower cloth groups 20 and 10 manufactured as described above are stacked. At this time, as schematically shown in FIG. 8, the upper cloth group 20 is slightly stretched in the width direction thereof, and the width thereof is increased between the outermost ends of the gusset cloths 30 attached to both side edges of the lower cloth group 10. Be approximately equal to the width of. This work can be easily performed by attaching the top cloth group 20 to a predetermined frame. Because the quilting 21a applied to the upper cloth group 20.
This is because 21b is made by zigzag stitching, and the fabric itself has elasticity, and in addition, elastic knit fabric is used as the side fabric.

[0016] Then, with sewing the two side edges 20a of the gusset fabric 30 and the upper cloth bodies 20, sewn together to what the side edges 10b · 20b of the lower futon body 10 and the upper cloth bodies 20. Thereby, the inside of the upper and lower cloth groups 20 and 10 can be closed. In this example, the top cloth group 20 is set in advance.
Extend the width of both side edges to the side edge of the gusset cloth 30.
In this state, stop the top cloth group 20 and the gusset cloth 30.
As you wear it, you can perform this fastening work efficiently and easily.
Can reduce the manufacturing time, and
The work burden can be reduced.

Next, the top cloth group 20 is removed from the frame. Then, the top cloth group 20 naturally shrinks, and the two-layer blanket with gussets (FIGS. 5 and 10) according to this example can be manufactured. In this state, the gusset cloth 30 is in an upright state, which has an advantage of high designability.

In the method of manufacturing the futon according to this example, as described above, the futon material 40 which becomes the lower cloth group 10 is continuously formed, and the gusset cloth 30 is continuously sewn to the side edges thereof. , This is cut to produce the lower cloth group 10 with the gusset cloth, and the double layer futon is manufactured using this,
Not only is it easier to manufacture a two-layer futon as compared with the conventional one, but the work of attaching the gusset cloth 30 to the lower cloth group 10 is also easy to automate and mechanize. From this point as well, work efficiency can be improved. You can That is, according to the manufacturing method of the present example, there is an advantage that it is possible to efficiently manufacture a two-layer futon with a gusset.

As the futon of this example, the upper cloth group 20
Although the knitted fabric is used as the side fabric, a satin fabric or the like may be used. Even in this case, the fabric can be stretched by performing the zigzag stitch, and the manufacturing method of this example described above can be carried out.

In the futon of this example, a long futon material 4 is used.
Although the width of 0 is made equal to the width of the lower cloth group 10, the width of the futon material 40 is made equal to the length of the lower cloth group 10, and the futon material 40 is cut at a width equal to the width of the lower cloth group 10. Accordingly, it is possible to manufacture the lower cloth group 10 in which the gusset cloths 30 are fastened to the side edges 10b at both ends in the length direction and sew the lower cloth group 10 to the upper cloth group 20.
Also in this case, since the gusseted cloth 30 can be easily fixed to the lower cloth group 10, the advantage that the manufacturing efficiency of the two-layer futon with the gusseted cloth is high can be exhibited.

In this example, zigzag stitching is used as a technique for quilting the top cloth group 20, but when sufficient stretchability can be imparted by using a knitted fabric, zigzag stitching is not used. Also, the above-mentioned advantages can be exhibited.

Further, it is not essential in the present invention to impart elasticity to the upper cloth group 20, and even if the upper cloth group 20 does not have elasticity, the above-described advantage of improving the manufacturing efficiency of the lower cloth group 10 is exhibited. It is possible to do so.

Further, in this example, the upper and lower cloth groups 20.10.
However, as shown in FIG. 10, one cloth group may have a larger shape in the length direction or the width direction than the other cloth group.

Also, in this example, the gusset cloth 30 and the cloth group 10
The fixing is made by sewing 20 together with 20. However, it is natural that the fixing may be made by an adhesive or the like.

Also, for example, the futon material 40 as in this example
After the gusset cloth 30 is continuously fastened to the base, the lower cloth group 10 is manufactured by cutting the gusset cloth 30 and then the gusset cloth 30 is sewn individually to the side edges not having the gusset cloth 30. Cloth group 2
A configuration in which 0 and 0 are sewn together may be used. Even in this case, the gusset cloth fastening operation on one side edge can be made efficient, and the futon manufacturing operation can be made efficient as a whole.

Further, in the present embodiment, a futon having a two-layer structure has been described as an example, but it goes without saying that a futon having three or more layers may be used.

[0027]

According to the method of manufacturing a futon according to the present invention, a futon material which is formed in a long shape and has a gusset cloth continuously attached to the side edges along the longitudinal direction is manufactured.
We cut the futon material in the width direction to manufacture the first cloth group,
By overlapping the first cloth group with the second cloth group and fixing the gusset cloth and the side edge of the second cloth group , the first cloth group and the second cloth group are separated. Since they are connected to each other, it becomes easy to mechanize and automate the production of the double-layered futon, and the efficiency of producing the futon can be improved.
