Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a futon.

Various methods of manufacturing futons have been known in the past, but among them, there is a method in which a plurality of sections extending in the back direction of the futon are formed by sewing a front fabric and a lining fabric in the back direction of the futon and are filled with cotton. Later, a method of manufacturing a futon by sewing across the back length has been known.

When manufacturing using this method, compressed air is used to fill synthetic cotton or the like into vertically long sections formed by sewing.

This requires a device and means for feeding compressed air, requires a relatively large space, and involves multiple steps, making it expensive. Furthermore, when compressed air is used to blow cotton into a vertically long compartment, the air temporarily remains in the vertically long compartment, so the cotton is often blown back from the compartment's entrance and scattered. The drawback was that it could not be done by an amateur.

The present invention was made in order to eliminate the above-mentioned drawbacks, and provides a futon that can be easily filled with cotton without using compressed air or other means, and in which the cotton does not scatter during the filling process. The purpose is to provide a manufacturing method.

Hereinafter, the method of the present invention will be explained in detail based on the embodiments shown in the drawings.

FIG. 1 shows a tunnel-style futon, in which a front fabric 1 and a lining fabric 2 are sewn together by perforations 3 formed in the vertical direction. Outer fabric 1 and lining fabric 2 defined by this perforation 3
Cotton 5 is filled in the compartment 4 between the two.

What is shown in FIG. 2 is a filling body 6, which is made by filling a predetermined amount of polyester synthetic cotton or the like into an elongated packaging body 7 made of transparent vinyl or the like having a small coefficient of friction. It is formed into a shape that can be inserted into the space 4.

Although the illustrated package 7 of the filler 6 has one end closed by a perforation 8 or the like, it does not necessarily have to be closed, and both ends may be open.

Next, a method of filling the tunnel-style futon constructed as described above will be explained.

A filler 6 is inserted into the compartment 4 between the front fabric 1 and the lining fabric 2, which are closed at one end of the tunnel-style futon, using suitable means such as rods or clamping members.
Insert.

Next, one end of the package 7 of the filler 6 is pulled to remove it. At this time, the packaging body 7 is made of a material with a small coefficient of friction, and the outer fabric 1 of the futon is
has a tendency to approach the lining fabric in two directions due to its own weight, and since the cotton 5 in the filling body 6 has a large coefficient of friction, the packaging body 7 can be easily pulled out.
After losing the wrapping body 7, the cotton 5 is made up of the outer fabric 1 and the inner fabric 2.
It fits tightly into the compartment 4 and is stably arranged within the compartment 4.

After pulling out the package 7, the open side of the compartment 4 filled with cotton 5 is separated from the outer fabric 1 and the inner fabric 2.
Closed by sewing together with a sewing machine,
Form a futon.

Figure 3 shows a honeycomb style futon, in which case the outer material 1 and the inner lining 2'
and "inner outer material 1' and lining material 2" are combined with the center part of section 4 touching each other, and "inner outer material 1' and lining material 2"
A further section 4' is formed between the inner surface material 1' and the inner surface material 1', resulting in a honeycomb-like three-layer structure.

In this case too, the filling body 6 is inserted into the compartments 4, 4', and after the packaging body 7 is pulled out, the compartments 4, 4'
The open side of the futon is closed to form a futon, and the filling method is the same as that for the tunnel-style futon described above, so a detailed explanation thereof will be omitted.

As is clear from the above description, the method of the present invention involves forming in advance an elongated filling body of a predetermined length filled with a predetermined amount of cotton inside a package with a small coefficient of friction;
The filler is inserted into a long and narrow section formed by vertically sewing the outer fabric and the lining fabric together using a sewing machine, etc., and then the packing body of the filler is cut out to separate the cotton between the outer fabric and the lining fabric. Because it is configured to fill a space, it can be easily filled with cotton without using compressed air or other means, and since the cotton does not scatter, it is inexpensive and can be handled by retailers and amateurs. Excellent effects can be obtained.

In the above description, the filling material is exemplified as cotton, but is not necessarily limited to cotton, and of course may be down or the like.

Claims (1)

[Claims] 1. In a futon production method in which a futon is manufactured by filling cotton into a plurality of sections extending in the back length, which are formed by sewing a front fabric and a lining fabric together in the back length direction of the futon, and then sewing them together across the back length, A packing body of a predetermined length filled with cotton etc. in advance was inserted into the compartment, and only the package was taken out from the compartment, leaving the cotton behind, and in this way all compartments were filled with cotton. A futon manufacturing method characterized in that the futon is then sewn together across the back length.
