Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a futon having a vent,
In particular, it relates to a method of manufacturing a comforter for summer.

[0002]

2. Description of the Related Art Conventionally, when manufacturing a futon, the side edges of two side fabrics are sewn together except for one side edge to form a substantially bag-like shape, and a batting is placed inside from the one side edge. After filling
The one side edge is sewn together and the inside is closed to manufacture a futon.

By the way, according to a recent study, particularly in a comforter for summer, it is possible to appropriately release the body temperature of the user of the futon to the outside by providing through holes for ventilation in predetermined positions of the futon. It has been found that it is possible to reduce sleepiness while preventing sleepiness.

However, it is difficult to form the ventilation holes in the completed futon because the batting is blown from the side cloth. Similarly, even if the vent holes are formed in the side ground in advance, the vent holes cannot be formed because blowing occurs when filling the batting.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and provides a method of manufacturing a futon in which ventilation holes can be formed in the futon without causing the batting of the batting. It is an object.

[0006]

In the method of manufacturing a futon according to the present invention, two side fabrics are arranged so as to overlap each other, and the overlapped state is set.
In, in forming a vent hole that penetrates both these side ground, sew two side ground so as to surround this vent hole,
Next, after filling the batting between the two side fabrics, the two side fabrics are sewn to manufacture the futon.

[0007]

EXAMPLE FIG. 1 shows a method of manufacturing a futon according to an example of the present invention.
~ It demonstrates based on FIG. First, the outline of the apparatus used in the method of this example will be briefly described.

This device is a device generally called a lace machine, and is composed of two frame bodies for supporting a long fabric in a tensioned state, and two frame bodies arranged so as to oppose each other in the front, rear, left and right directions. It is equipped with a movable sewing machine. The structure of this sewing machine will be described with reference to FIG. 1. This sewing machine includes a needle 1 and a cone 2 which are vertically spaced apart from each other and arranged in parallel. A large number (about 700 sets) are arranged along the longitudinal direction of the frame body. A sewing thread is attached to the needle 1, and the needle 1 is configured to sew the sewing thread to the cloth by back and forth movement. Further, the cone 2 has a diameter larger than that of the needle 1, and moves back and forth independently of the needle 1 to form a through hole in the cloth. This race machine has almost the same configuration as that of a widely known one, and thus detailed description thereof will be omitted.

Next, the method of this example will be described. First, as shown in FIG. 2 and FIG. 3, long fabrics 3a and 3b are respectively stretched and stretched on two frames of the race machine. In this state, the length L of the cloth is 20 m and the width W is 162 cm. Further, in this state, both side edges of the cloth in the width direction are wound around the frame (see FIG. 3, only the cloth attached to one frame is shown in FIG. 3). .

Next, the sewing machine 1 is operated so that the material 3a
Perform race forming work for 3b. Hereinafter, this work will be described with reference to FIG. That is, the cone 2 of the sewing machine 1
By forming a large number of vent holes 10 penetrating both both fabric 3a · 3b in the state of being superimposed. afterwards,
The inner edge of the vent hole 10 is bent down. In this example, the six ventilation holes 10 are a unit of one pattern, and six patterns are formed in the width direction and five in the longitudinal direction to form one futon pattern, and this pattern is the fabric. 8 pieces are formed so as to be continuous in the longitudinal direction of 3a and 3b.

Simultaneously with or before or after this work, 2
The fabrics 3a and 3b are sewn together with the embroidery thread passed through the needle 1 around the six vent holes 10 forming one handle. Thereby, the surrounding portion 11 surrounding the ventilation hole 10 can be formed. Further, by the needle 1, the surrounding portion 11 along the longitudinal direction of the fabrics 3a and 3b.
The fabrics 3a and 3b are sewn together so that they are connected to each other. As a result, so-called five vertical quiltings 12 can be formed. Also, at this time, dough 3
Sew both edges along the longitudinal direction of a and 3b together.

Next, the cloths 3a and 3b are removed from the frame of the lace machine, and the cloths 3a and 3b are moved in the width direction at every length of about 2 m (at each position shown by a chain line L1 in FIG. 2). It is possible to cut and produce 8 side materials per 1 piece of raw material 3a, 3b.

Then, after sewn together one end in the lengthwise direction of the side ground to close it, a feather (wadding) is blown into the side ground from the other end, and the other ends are sewn together. Close. As a result, the down can be enclosed inside the lateral area to obtain the futon. here,
In the method of this example, the ventilation holes 10 are formed and the surrounding
The formation of the jutting part 11 and the two sheets of cloth
(Ground) 3a and 3b are overlapped in advance , so
The futon having the pores 10 can be efficiently manufactured.
There is an advantage. In addition, this work is the same as the race
Since it can be done automatically using a machine,
It is easy to automate the manufacturing process of the team, and the manufacturing efficiency
Can be further improved. 2 more dough
A large number of ventilation holes 10 are formed in the
The surrounding portion 11 is preliminarily formed by stitching 3a and 3b together.
Vents 1 filled inside the side ground
Feather does not blow out from 0. That is, according to the method of this example, there is an advantage that it is possible to form the ventilation holes 10 in the futon while preventing the batting of the batting.

Then, the two side fabrics containing the feathers are sewn in parallel in the width direction (lateral direction) at regular intervals,
The quilting 13 is formed. The position of the quilting 13 is approximately the middle position between the surrounding portions 11.

According to the method of this example, the long fabrics 3a, 3a
lace on b, 8 pieces for each cloth 3a and 3b,
Since the upper and lower fabrics can be summed to produce 16 laterals at once, there is an advantage that the laterals are highly efficiently manufactured.

In the method of this example, the long fabric 3a
The lace was applied to 3b to produce eight side fabrics at a time, but it is also possible to manufacture the futon of this example by performing lace using a cloth that has been cut into the size of the futon in advance. Is natural.

[0017]

According to the method of manufacturing a futon according to the present invention, two side grounds are arranged so as to overlap each other, and in this superposed state, a vent hole is formed which penetrates both side grounds, and the vent hole is formed. Since the two side fabrics are sewn together so as to surround them, and then the batting is housed between the two side fabrics, the two side fabrics are sewn to manufacture the futon, so that the ventilation hole is formed. Have
Moreover, the futon prevents the batting from blowing out from the ventilation holes.
Can be manufactured efficiently, and
It has a practically important effect that it can be easily mobilized .
