Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a hat that fits well to the shape of the head, such as a swimming cap.

Prior Art Conventionally, when manufacturing a swimming cap, for example as shown in FIG.
and the cylindrical tightening part 22 are cut from desired fabrics, and then the edges of the cut parts are sewn together to manufacture a hat of a predetermined shape.

Problems to be Solved by the Invention However, in the method of manufacturing a hat having the above structure,
There are problems in that there are many scraps when cutting, which tends to cause waste, and there are many parts to be sewn, which is complicated.

Therefore, the present invention aims to solve the above-mentioned problems by making it possible to integrally knit a fabric into a predetermined shape without cutting it, thereby reducing scraps and simplifying the manufacturing process. The purpose of the present invention is to provide a method for manufacturing hats.

Configuration, operation, and effect of means for solving the problems In order to achieve the above object, the present invention is configured to knit with a circular knitting machine. In other words, a main body portion consisting of at least a first knitted fabric and a second knitted fabric that has more stitches than the first knitted fabric and is continuous to the first & Knit the tightening material part integrally with a circular knitting machine, align the upper end periphery of the first knitted fabric on the side opposite to the second knitted fabric in a straight line, cut the corner parts of both ends, and cut the belly cut part. The first knitted fabric was sewn together to form a hemispherical shape.

Here, "aligning the upper edge of the first knitted fabric in a straight line, cutting the corners of both ends, and sewing the cut parts together" means, in the simplest case, pinching the entire upper edge of the fabric in a straight line and sewing the seam line. In other cases, the suture line may be cut and sutured in a direction perpendicular to the straight line, such as a cross shape, or a figure 7 shape, etc. means.

According to the above configuration, the main body part and the tightening part can be continuously knitted by the round iiiso, and mass production can be achieved, thereby reducing costs. That is, instead of cutting the fabric into a predetermined shape and sewing it, most of the hat can be manufactured continuously and integrally by knitting, and the upper edge of the first knitted fabric is cut and sewn to close the upper part of the main body. Hats can be manufactured with just one person, simplifying the manufacturing process and making it possible to automate it.

Furthermore, by knitting the main body using a circular knitting machine, it is possible to freely knit various knitted palm patterns.

Furthermore, since the knitted fabric itself has elasticity, it can easily fit around the head.

Embodiments The present invention will be specifically explained below based on illustrated embodiments.

FIG. 1 is a side view showing a hat manufactured based on the hat manufacturing method according to this embodiment, and FIG. 2 is a plan view of the hat.

The hat is generally composed of a main body part 7 that covers the head, and a tightening part 1 that tightens the forehead part and fixes the hat to the head.

The main body portion 7 includes an eleventh knitted fabric 4, a second knitted fabric 3, and a third knitted fabric 2. After the first knitted fabric 4 is knitted into a cylindrical shape, the upper edge is cut into a curved shape, and the cut edge is sewn to form a hemispherical shape, forming the top of the hat.

The second knitted fabric 3 is integrally and continuously knitted around the lower edge of the 11th IA fabric 4, and has a greater number of stitches than the first knitted fabric 4, as shown in FIG.

Further, the third &i fabric 2 is knitted continuously and integrally with the lower edge of the second knitted fabric 3, and has more stitches than the second knitted fabric 3. The number of stitches increases toward ground 2.

On the other hand, the tightening portion 1 is made of elastic thread such as spandex. It is integrally and continuously knitted around the lower edge of the i fabric 2, and the number of stitches is approximately the same as that of the third knitted fabric 2.

Since this tightening part 1 is knitted with elastic yarn, the main body part 7 (1) also has great elasticity, so that the forehead can be tightened and the hat can be fixed on the head.

The main body part above? The knitting structure of the tightening portion 1 may be any knitting structure such as plain knitting.

The above hat is manufactured on a circular knitting machine as follows. That is,
First, the first knitted fabric 4 is knitted by a predetermined width.

Next, the second knitted fabric 3 is integrally and continuously knitted around the lower end of the i1-th fabric 4 so that the number of stitches is increased, for example, twice as many as in the first N-th fabric 4.

As a method for increasing the number of stitches in this way, the method of increasing the number of stitches is as follows.
As shown in the schematic diagram in FIG. 7, in the Maru I machine, the knitting needles 9. . . , 9 are used, for example, every third needle to hook the knitting yarn 10 to knit the first knitted fabric 4, and then, for example, every other needle is used to hook the knitting yarn 10 using knitting needles 9° . . . , 9. , and form the second knitted fabric 3 by &ii.

In fact, the circle has around 400 knitting needles in total!
Organize with i machines.

Next, in the same way, the third knitted fabric 2 is made so that the number of stitches is twice as large as that of the second knitted fabric 3, for example, on all the needles 9. ...,
In step 9, the second knitting is knitted continuously and integrally around the lower edge of the fabric 3.

Next, a highly elastic tightening part 1 is knitted continuously and integrally with the lower end periphery of the third knitted fabric 2 using elastic yarn using the same stitches as the third knitted fabric 2.

Next, the upper end periphery of the first knitted fabric 4 is pinched together in a straight line, and then cut at the curved corners of both ends as shown by dotted line 6 in FIG. 3, and both edges are cut at 5 in FIG. Stitch in a straight line as shown. Therefore, it is possible to manufacture a booklet in which the upper part of the main body part 7 has a concave shape.

According to the above embodiment, the main body portion 7 and the tightening portion 1 can be continuously mass-produced using a circular knitting machine, and costs can be reduced. Also, Maru a! By using a machine, the knitted pattern and striped pattern can be easily formed on the main body 7 and the like. Furthermore, since the knitted fabric itself has elasticity, it can easily fit around the head.

Note that the present invention is not limited to the first embodiment described above, and can be implemented in various other forms. For example, if the knitting yarn of the main body part 7 is an elastic yarn, the upper part of the first knitted fabric 4 and the upper part of the second knitted fabric 3 will be rounded so as to enter inward in the radial direction, so that the shape of the main body part 7 will be changed. It becomes more rounded. Furthermore, instead of knitting with elastic yarn, the tightening part 1 may be knitted with the same knitting yarn as the main body part 7, and a rubber thread may be passed through the braided fibers to give it extraordinary elasticity. good. Also, cut the periphery of one end of the 11th IA ground 4.
When stitching together, the cutting operation and the stitching operation may be performed simultaneously by so-called overlocking. Also, the peripheral edge of one end of the first knitted fabric 4 is cut in the thickness direction of the paper as compared to FIG. 3, so that the seam line forms a cross shape in the plane of the hat, making it more rounded. Good too. Furthermore, the main body portion 7 may be knitted with two or four or more knitted fabrics.
