Description

[Detailed description of the invention] "Industrial application field" This invention relates to a method of manufacturing a comforter.

"Prior art and its problems" Conventionally, in the case of comforters that use feathers as filling, multi-F partitions are used on the inner surface of the upper and lower sides of the comforter for the purpose of preventing the feathers from moving and preventing the cotton from bunching up. 2. Description of the Related Art A so-called three-dimensional quilt type comforter is known in which fabrics are fastened orthogonally to each other to form a plurality of compartments, and feathers are stored in the compartments. Normally, to manufacture this three-dimensional quilted futon, one piece of fabric is used for the front and back sides, and a partitioning cloth is attached to the inner surface to sequentially form a large number of sections. At the initial stage of fastening the partition fabric, the fastening goes smoothly, but as multiple sections are formed, depending on the order of sewing, the fastened partition fabric may form a bag-like shape, and the sewing machine's hook will not fit into the partition cloth. may not be able to be sewn. In addition, since a large number of partition cloths are sewn onto the inner surface of the side fabric, it is difficult to sew the partition cloths, and the seams are bent, resulting in an unfinished finish, which detracts from the appearance of the futon and reduces its commercial value. Also, when storing feathers, insert a hose through the feather insertion hole provided on the side edge of the side fabric, pass this hose through the gap formed at the intersection of the vertical and horizontal partition fabrics, and insert the feathers into the compartments one by one. A method is being taken. However, this method has a problem in that it is difficult to insert an average amount of feathers into each section in a short time because the work is done by hand in the side fabric.

This invention was made in view of the above circumstances, and it is possible to form the outer fabric from a plurality of pieces of outer fabric so that it is easy to sew the partition fabric, and the stitches of the partition fabric are finished neatly.
Moreover, it is an object of the present invention to provide a method for manufacturing a comforter that allows easy insertion of feathers into each compartment.

[Means for Solving the Problems] The method for manufacturing a comforter according to the present invention includes forming a plurality of first partition cloths and second partition cloths on the inner surfaces of the outer fabric and the inner fabric, respectively, so as to cross each other at predetermined intervals. In a method of manufacturing a comforter in which feathers, etc. are stored in a plurality of compartments formed by fastening, the side edges of adjacent outer fabric pieces are sewn together to form a feather insertion hole in the outer fabric. using the
The outer fabric is fastened to a first partition cloth and a second partition cloth to form a plurality of compartments together with the lining fabric, feathers are inserted into the compartments through the feather insertion opening, and then the feather insertion opening is secured. and will be closed.

"Example" An example of the method for manufacturing a comforter according to the present invention will be described based on the drawings. 1 to 5 show one embodiment of a comforter according to the manufacturing method of the present invention. First, as shown in FIG.
A tape-shaped second partitioning cloth piece 5a formed in two widths is attached at predetermined intervals by a multi-head sewing machine so that one edge in the longitudinal direction is attached along the length of the lining fabric 3. Furthermore, a plurality of tape-shaped first partition cloths 4 are attached at predetermined intervals to the inner surface of the lining fabric 3 to which the second partition cloth pieces 5a are sewn.
It is attached by sewing one longitudinal edge of the partition cloth 5a orthogonally to the partition cloth piece 5a using a multi-head sewing machine. By sewing in this way, the seams will not bend and will be finished neatly. Then, the second partition cloth piece 5a sewn to the lining fabric 3
A notch 7.7 is provided at the intersection with the first partition cloth 4 to allow the second partition cloth piece 5a to be raised along the seam 6 of the first partition cloth 4, as shown in FIG. .

On the other hand, the outer fabric 2 is formed by sewing the side edges 8 of a plurality of rectangular outer fabric pieces 2a next to each other as shown in FIG. A plurality of strip-shaped second partition cloth pieces 5b formed on the inner surface of the outer fabric piece 2a to have a width 1/2 of the width of the first partition cloth 4.
Cut so that one edge in the longitudinal direction is parallel to the side edge in the longitudinal direction of the futon, and at the same interval as the sewing interval of the second partition cloth piece 5a sewn to the lining fabric 3. Attach by sewing with a multi-head sewing machine. By sewing the partition cloth separately to the front fabric piece 2a and the lining fabric 3 in this way, it is easy to sew the partition fabric to the side fabric, and the seams do not bend. In this case, a seam allowance 18 is provided at the side edge 8 of the sewn portion of each outer fabric piece 2a for sewing adjacently. Next, the inner surface of the outer fabric piece 2a and the inner surface of the lining fabric 3 are made to face each other, and one edge of the second partition fabric piece 5b is sewn to the inner surface of each;
The opposite edges of 5a are sewn to each other using a sewing machine or the like to be connected as one unit. The second partition cloth 5 is formed by arranging the second partition cloth pieces 5a and 5b in a row in this manner. In this case, each outer fabric piece 2a can be sewn sequentially to either the left or right side as shown in FIG. 3, so that it becomes bag-shaped and does not require a sewing machine hook, making it extremely easy to sew.

After all the second partitioning cloth pieces 5a, 5b are arranged in a row in this way, the side edges 8 of the adjacent outer cloth pieces 2a are sewn to each other. The other edge 9 of the first partition cloth 4, whose lengthwise edge is sewn to the inner surface, is also sewn together with the side edges 8.

The suturing method will be explained based on FIGS. 3 and 4.

First, the seam allowance 18 of the side edge 8 of the adjacent outer fabric pieces 2a
are each folded in half to form pleats (bent portions) 10.10 in the width direction of the futon. Next, the above for any one outer fabric piece 2a! The other edge part 9 of the first partition cloth 4 is sandwiched between the inner surface of the I (bending part) 10, and the adjacent outer fabric pieces 2a, 2a
The pleats 10 and 10 are sewn together by forming an unsewn portion equal to the width of the feather insertion opening 11 (indicated by a dashed line in FIG. 5) into the compartment 12 that stores the feathers. In this way, the outer fabric 2 is formed by sewing the pleats 10.10 of each outer fabric piece 2a, 2a. In addition, the other edge 9 of the first partition cloth 4 is also
At the same time, they are sutured and connected. By sewing the outer fabric pieces 2a, 2a prepared in advance in this way, it is easy to sew with a sewing machine, etc., the seams are finished in a straight line, and the other edge 9 of the first partition cloth 4 can be sewn at the same time, so it is not possible to sew the outer fabric pieces 2a, 2a prepared in advance. This is easier to do than sewing it to the inner surface of a single piece of outer fabric.

Further, the pleats 10 also serve as a decorative pattern on the surface of the outer fabric 2. Next, the outer fabric 2 and the inner fabric 3 are overlapped and their peripheral edges are sewn together by hemming or the like.

As described above, the compartment 12 for storing feathers is formed in the futon side fabric 1.

Next, a hose for pressure-feeding feathers is inserted into each section 12 from the feather insertion port 11, and the feathers are force-feeded using compressed air. In this case, since the feather insertion opening 11 communicates with the two adjacent compartments 12 via the first partition cloth 4, one feather insertion opening 11 is used to directly insert the feathers into the two compartments 12.12. can do. As described above, since the feathers are directly pumped from the surface of the outer material 2 to each section 12, the feather insertion work is easy, and since the feathers are inserted visually, an average number of feathers can be inserted into each section 12. After the feather insertion is completed, the feather insertion opening 11 is sutured and closed.

Next, quilting 13 is applied to the four corners of the forehead of the futon. Futon A is completed through the above-mentioned steps.

In the above embodiment, the outer fabric piece 2a was cut in the width direction of the futon A, but it may be cut in the length direction. Further, although the first partition cloth 4 is sewn in the width direction of the futon, the present invention is not limited thereto, and may be sewn in the length direction of the futon. In this case, the pleats 10 are formed in the length direction of the futon.

Further, in the above embodiment, the outer fabric piece 2a was cut into rows of sections 12, but as shown in FIGS. You may cut it so that it is covered with. In this case, the folds 10 of the outer fabric piece 2a in the center
A is attached to the inner surface of the first partition cloth 4 with the other edge 9 sandwiched therebetween. In addition, first, a band-shaped second partition cloth 5 is attached to one piece of the outer fabric 2.
The outer fabric pieces 2a may be formed by sewing parallel to the length direction using a multi-head sewing machine, and then cutting the outer fabric 2 in the width direction. Also, the second partition cloth 5 is divided into second partition cloth pieces 5a and 5b.
Although the second partition cloth 5 is formed by consecutively arranging two pieces of fabric, the second partition cloth 5 may be formed of one piece of fabric. Further, in the above embodiment, at the intersection of the first partition cloth 4 and the second partition cloth 5, the first
The side surface of the partition cloth 4 and the end of the ~J2 partition cloth 5 are not sewn, and a gap 17 is formed between them.
As shown in FIGS. (A) and (B), the side surface 14 of the first partition cloth 4 and the end portion 15 of the second partition cloth 5 may be sewn together with a gore cloth 16 so as to be connected. When the gore cloth 16 is sewn in this way, the gap 17 is closed and the feathers do not move through the gap 17, so that it is possible to prevent the cotton from bunching. Note that the relationship between the front fabric and the lining fabric of the comforter according to the manufacturing method of this invention is relative, and is not restricted to the literal meaning of the front and back.

"Effects of the Invention" The method of manufacturing a comforter according to the present invention involves fixing a plurality of first partition cloths and second partition cloths to the inner surfaces of the front fabric and the lining fabric, respectively, by crossing each other at predetermined intervals. In a method for manufacturing a comforter in which feathers, etc. are stored in a plurality of formed compartments, the side edges of adjacent outer fabric pieces are sewn together to form a feather insertion hole in the outer fabric,
The lining fabric is fastened to a first partition cloth and a second partition cloth to form a plurality of compartments together with the lining fabric, feathers are inserted into the compartments from the feather insertion opening, and then the feather insertion opening is fastened. Since it is constructed so as to be closed, the partitioning cloth forming the compartments can be easily fixed to the front fabric and the lining fabric, and the seams are neatly finished without bending, making it possible to manufacture a comforter with high commercial value. Furthermore, it is easy to insert feathers, and the feathers can be inserted evenly into each compartment, resulting in extremely high work efficiency.
