Description

[Detailed description of the invention] Pocket bags for pants, etc. are made by overlapping two pieces of cloth,
The periphery is sewn to form a bag-like shape. Conventionally, as shown in Fig. 11, the method of sewing the periphery is to attach tape e, which is a separate cloth, to three sides of two overlapping pieces of cloth. It was common for the fabric to be completely sewn.

In the conventional type shown in Fig. 11, a tape made of a separate cloth is used, which is cumbersome to do, and in order to provide a pocket opening a, a cut is made in one piece of cloth.
In order to create the pocket opening, it was necessary to sew the notch again after processing the pocket opening a.

Therefore, it was only possible to make a pocket opening with a width W smaller than the pocket width W.

In addition, the sewing position C of the notch b is located inside the three-wrap sewing position d of the pocket, resulting in an unsightly product.

Therefore, in the present invention, one piece of cloth is made into a slightly larger large piece of cloth 1, its peripheral part is rolled up, and the other small piece of cloth 2 is sandwiched in and sewn into three wraps, without using a tape which is a separate cloth. , and has invented a method that can be manufactured efficiently.

In other words, one of the difficulties with the three-wrap sewing method using tomo fabric is the work of setting the cloth piece in a sewing machine for three-wrap sewing, but the present invention can be used to sew two pockets. The sewing process can be performed in one set, increasing production efficiency.

Hereinafter, the present invention will be explained based on the accompanying drawings.

Figures 2 to 6 of the attached drawings show examples of pocket bags shaped to be applied to hip pockets of pants, etc.
Moreover, FIGS. 7 to 10 show embodiments of pocket bags applied to side pockets of pants.

First, a method of manufacturing a pocket bag applied to hip pockets of pants will be explained with reference to FIGS. 4 to 6.

To make a pocket bag, a large cloth piece 1 and a small cloth piece 2 are used.

As shown in FIG. 4, the large piece of cloth 1 whose peripheral edge is to be folded has a size that is the size of two pieces butted together centered on one side that will be the upper side of the pocket that will not be sewn.

Then, a notch 5.5 is provided from both left and right sides on the center line A folding piece 7 that can be folded back is formed.

The cuts 3, 3 located at vertically symmetrical positions are diagonal and widen inward.

As shown in FIG. 5, the small piece of cloth 2 to be superimposed on the large piece of cloth 1 is the same size as the large piece of cloth 1 and has the size of two pocket bags.

Then, a notch 8 is provided from either the left or right side on the center line 4
will be established.

The upper and lower edges of this lug piece 4 are diagonally expanded outward in the opposite direction to the notch 3 of the large cloth piece 1.

To sew a pocket bag using the large cloth piece 1 and the small cloth piece 2, as shown in FIG. Lay the cloth pieces 2 on top of each other.

Then, insert the tips of the selvedges 4.4 of the small cloth piece 2 under the large cloth piece 1, and start sewing three wraps from the notch 8 of the small cloth piece 2. You can sew continuously across the length.

Only the selvedge piece 4 of the small piece of cloth 2 is wrapped three times around the folded piece of the large piece of cloth 1, but the tip of the selvedge piece 4 overlaps the periphery of the large piece of cloth, resulting in loss of continuity. You can proceed with the sewing work without any problems.

However, the large piece of cloth and the small piece of cloth may be glued together in this area.

Thereafter, by cutting along the center line X, two pocket bags can be obtained.

In the pocket bag manufactured by the manufacturing method of the present invention, as can be seen from FIGS. 2 and 3, an unsewn part A where two pieces of cloth are not sewn is formed at the upper end of the pocket bag, and the pocket bag is It can be made convenient for mouth processing.

Next, a description will be given of a type of pocket bag that is applied to side pockets of pants.

As shown in FIG. 7, a pocket bag used as a side pocket has an upper side 9 and a diagonal side 10 that are not sewn, and the upper side 9 is sewn to the trouser fabric when sewing the trousers. A pocket opening is machined on side 10.

Therefore, the present invention forms an unsewn part A where the large cloth piece 11 and the small cloth piece 12 are not sewn at the starting end of the three-wrap stitch at the lower end of the side 10 that should become the pocket opening. He invented a manufacturing method that not only facilitates the processing of pocket openings but also allows two pocket bags to be sewn at once.

Next, the manufacturing method will be explained with reference to FIGS. 8 to 10.

As shown in FIG. 8, the large piece of cloth 11 whose peripheral edge is to be folded has a symmetrical shape in which two pieces are butted against each other with the side corresponding to the upper side of the pocket bag as the center.

Cuts 13 are provided in the upper portions of both the left and right sides of the large cloth piece 11, and the portions are folded back along fold lines 14 extending from the tips of the cuts 13 to the middle part of the upper side in the drawing as folded pieces 15.

As shown in FIG. 9, the small piece of cloth 12 to be overlapped with the large piece of cloth 11 has a large length from its upper side to the upper end on both left and right sides (corresponding to the part where the cut 13 of the large piece of cloth 11 is made). It has the same shape as the cloth piece 11, and the lower part is the large cloth piece 1.
It should be one size smaller than 1.

In other words, the ears 16, 16 are formed on both left and right shoulders of the small cloth piece 12.

The tip of the selvage piece 16 is wedge-shaped so as to overlap the large cloth piece.

In a pocket bag of this shape, the side edge where the pocket opening should be formed (corresponding to the top edge of the cloth piece in the drawing) is not sewn, so it is sewn from the top edge of one side through the bottom edge to the top edge of the other side. All you have to do is sew up to that part.

During the sewing work, as shown in FIG. 10, the folded pieces 15 at both the left and right shoulders of the large cloth piece 11 are folded back, the small cloth piece 12 is placed on top of the folded pieces 15, and the tips of the selvedge pieces 16 are folded into the large cloth piece. Place it under 11.

Then, start sewing three wraps from one part of the selvage piece 16 of the small cloth piece 12, and move from the side edge to the bottom edge, and then the side edge to the other selvage piece 16.
Sewing up to.

Therefore, it is possible to form an unsewn part A in which only the selvage piece 16 is wrapped around the selvage piece 16 and the large cloth piece 11 and the small cloth piece 12 are not sewn. Since the tip is under the large piece of cloth, it can be advanced continuously.

Of course, the selvedge pieces 16 may be adhered to the large cloth piece 11 in advance.

If the product thus produced is cut along the center line X, two pocket bags, one shown in FIG. 7 and one laterally symmetrical to this, can be obtained.

According to the method for manufacturing pocket bags of the present invention, when manufacturing pocket bags, two pieces can be successively sewn by performing one set of three-wrap stitches, thereby increasing the production efficiency of pocket bags. can be significantly improved.
