Design Of Shoes With Bottom Covers -- Design Features

The bottom shoe is a kind of slit shoe that is directly linked to the sole of the foot through the integration of the shoe and the insole.

Although the bottom shoe also belongs to the seam ridge shoes, the difference between the shoe and the ordinary seam ridge shoe is the carefully designed wrinkles on the periphery of the shoe ridge.

The bottom of the shoe is very much like a kind of food called "baozi". So in the north, it is often called "baozi shoes". In Shanghai, it is called "burn shoes" in Guangzhou, and dumplings are called "dumpling shoes" in the northern part of the country.

In other countries, the bottom shoes are mocashin shoes, which are plated by Moccasin and plated by Ma Xun.

The shoe is a soft, foot wrapped deer leather shoe worn by Native Americans.

The structure of the bottom shoe is characterized by the integration of the shoe round bar and the inner bottom.

The typical bag bottom shoes do not need or use less shoes, no inner bottom or only half inner bottom, and no hooking. Soft soles can bend in the wine cup. When wearing, the feet are directly on the soft fabric, which is breathable and comfortable, and feels very comfortable.

See color K series.

The color picture K-4 is a wrinkled head shoe. It has wrinkles on the base of the seams. The appearance is much like the bottom of the shoe, but it doesn't have the structure of the genuine bottom shoe. It is used to be called fake baozi shoes.

The color picture K-5 is a bag bottom shoe, not only has the shoe ridge and wrinkles, but also the upper and the insole are linked together, that is, the upper is wrapped up from the insole, and is commonly called "baozi shoes".

1. last type characteristics

The design of the bottom shoe requires a special bottom shoe last.

This type of shoe last is characterized by a relatively upright erection of the shoe last wall and the wall. It is obvious that the wrinkles on the bottom of the shoe can be placed on the wall of the last wall, and the shape of the three-dimensional wrinkle can still be maintained after the shoes are made.

If you use the ordinary shoe last to design the bottom shoe, you can't see the effect of the steamed buns, steamed dumplings and dumplings.

The tongue type shoe sole should be used for designing the tongue bottom shoe. The design of the outer ear type shoes should be made of prime shoe bottom and shoe last.

The difference between the bottom shoe last and the ordinary tongue last and the prime last is not very different from the length and the circumference of the shoe last.

When you check the size table of the last body, you can only find a female last called wrinkled head last. It is basically the same size as the same type of 16.5mm with the same height, but the thickness of the last head is thickened from the original 18mm to the thickness.

For men's shoe last, because the allowance is larger than that of the female last, the thickness of the last shoe is enough to be used. It only needs to change the shape at the front of the last, and the data used are unchanged, so there is no single size table.

The last wall of the shoe last shoe last line is more obvious, it can be seen directly on the shoe last, or it can be directly touched. The shoe last shoe design has good effect and can meet the aesthetic requirement.

Generally, the bottom shoe last, the heel is relatively short, the last body is small, the middle waist is straight, so it is suitable for the design of the "bottom" structure.

In addition, most of the last ones are middle round heads, which is conducive to the uniform distribution of wrinkles.

Some shallow enclosure shoe last also applies to design bottom shoe.

In the factory before, there were special master repair masters to modify the ordinary shoe last to modify the shoe last for the design of the shoe.

The industry of the last industry is also very developed. It can provide all kinds of shoe last. It only needs to buy the last type of shoe suitable for the design of shoe bottom.

2. structural characteristics

From the perspective of large structure, the bottom shoe is also a kind of cover shoe, which is a kind of shoe with a wrinkle in the cover shoe.

The reason for emphasizing the big structure is that before designing the bottom shoe, we must first master the design of the shoe.

In view of the specific structure, the round bar parts and the inner part parts are integrated into one body, and after the support is used, the last casting process is formed.

The key content of the design is how to achieve a good combination of the fence and the bottom.

How does the wrinkle appear on the shoe's head?

If the length of the surround strip is much larger than that of the shoe cover, then the head and tail must be aligned when inserting, so the amount of length will exist in the form of wrinkles.

The crevice of the bottom of the suture bag is usually made by hand stitching. The number of holes in the sill must be equal to the L number of the shoe cover. However, the distance between the holes is different, and the distance between the holes is relatively close. The amount of the distance between the holes on the fence is the size of the wrinkle.

The bottom of the seam can also be sewn by Mark machine.

When machine sewing is used, it is necessary to use the shrinkage machine to "wrinkle" and fix the wrinkles before sewing with the machine.

3. special requirements

There are three special requirements for designing the bottom shoe.

(1) the bottom template of the shoe bottom is reduced by about 3mm compared with the ordinary bottom.

Why should we shorten it?

It is known that stretching can eliminate wrinkles on the surface, but the bottom shoe is molded by the last molding process. There is no chance to stretch the stretch. Therefore, the method of shortening the last bottom template is adopted to make the surface stretch when the last set is used, and the 3mm foot is used to supplement the last bottom.

Where is the shortening position?

It is usually shortened in the toe position, as shown in figure 2-5-1.

Shorten the length of 3mm in the middle line of the toe of the shoe, and connect the contour lines on both sides.

 

(2) the design of shoes with half panels inside and outside is used only in the half panels on the outer side, and the components in the arms are found through the difference between the inside and outside.

The design of the bottom shoe requires a strict "parcel" for the last body, so it is necessary to prepare the half panels on both sides of the inside and outside, that is, to distinguish the difference between the inside and outside.

(3) determine the number of playing L on the shoe cover, determine the number of holes on the shoe cover is the key, and the number of holes on the surround is determined according to the number of holes in the shoe cover.

The hole spacing on the shoe cover is shown in table 2-5-1.

 

Mark in the drawing and punch out the hole when the template is taken.

When there is a difference between the inside and outside, there is no need to change the number of holes.

Before the turning of the front arc, there are 7 holes. The distance between the holes is 5mm. It is recorded as 7/5. After the turning of the front arc, there are 14 holes, and the distance between the holes is 6mm, which is recorded as 14/6.

The number of holes on the fence should be equal to the number of holes in the shoe cover, and the spacing between holes should be determined according to the requirements.

There are different types of subdivision shoes: one is the fake bag bottom shoe, the other is the half bag bottom shoe, one is the full bottom shoe, and the other is the wrinkle bottom shoe.

Through the design practice of the fake bottom shoe, you can first grasp the requirements of the bottom shoe for punching.
