The function of the shoe lining is to increase the hygiene, comfort, reinforcement or warmth retention of the shoe cavity.

Therefore, the design of the shoe is not simply duplicating the plaid template, it should strive to be concise and minimize unnecessary breaking position.

If there is a broken line, it should also be staggered with the broken line of the side to make the upper flat and not rubbing the feet.

When the handwork is used, the design of the shoe bottom can not distinguish the inside and outside; because of the operation process of "picking up", the design of the machine is different. Because of the different operation principle of the front and the back, the front bottom must have the difference between the inside and outside.

The structure of shoe lining is divided into whole, two and three segments. The technical requirements for designing different shoes and shoes are roughly the same.

(1) technical requirements for shoe lining design

1. stubble quantity and stubble quantity

The edge of shoe parts also needs to be overlapped during processing. The amount of overlap with fixed relation is called stubble quantity, and the amount of overlap without fixed relation is called stubble.

There are differences between stubble and small stubble.

The big stubble is used for inserting in the front and back sides. It is 8 ~ 9mm, and the small stubble is used for inserting the body to 4 to 5mm.

For example, the two segment or the three segment front and the back sides need to add 8 to 9mm, and the latter needs to add 4 to 5mm.

2. punching edge

In order to ensure the quality of the shoes, shoes and ears, the tongue and other parts and the sewing quality of the shoes, it is necessary to release more processing quantities and flush the shoes, and the amount of processing that is washed away is called punching edge.

Punching edge and adding 3mm.

3. contraction of bottom outlet

In order to improve the bonding strength between the surface and the shoe and the inner part of the shoe, it is necessary to put a certain amount into the bottom of the shoe. The amount of shrinkage is called the shrinkage of the bottom.

The shrinkage of the bottom mouth is 6 ~ 7mm.

4. rear arc reduction

When the shoe is inside, the shoe inside is in the outer ring, so the shoe should be shortened. The reduced amount is disposed at the rear arc, so it is called the reduction of the rear arc.

The general back arc reduction has 2mm, but when dealing with the original template, D points add Imm, B points add 2 to 3mm, and the reduction of the rear arc needs to reduce the amount of additional addition, so it is different in Q, D and B.

General control Q. point 2mm, D points into 3mm, B points into 5mm.

5. front tip reduction

In front of the tip, there should be some inner Baotou. Some capacity should be set aside. The way to control it is to reduce the anterior cusp, so it is called the anterior apex reduction.

The position of the control is located at the front end of the bottom port. After lowering the 2mm, the back midline of the shoe is designed.

6. rear suspension

The rear hanger is used for the shoe in the long back to prevent the shoe from sticking down.

For example, when designing women's shallow shoes, they need to have back skins.

Sometimes, in order to be simple, it can also retain a small distance of shoe inside instead of rear suspension.

The position is kept at 1 / 2 of the back length.

The rear hanger is indicated as lOmmX 5mm.

The above is the control requirements of the shoes in general and women's shallow shoes. For sandals and boots, there will be some special requirements, which will be discussed in the later chapters.

(two) design of inner ear shoe lining

1. the design of the former Gang

(1) when designing the front part of the front part of the two head shoes, draw the outline line of the front half of the front part, and then make the specific design.

The steps are as follows:

Position 2mm at the front end of the bottom opening, then connect to the door position and extend back as the back line of the shoe lining.

Along the contour of the shoe, evenly add 8 to 9mm stubble.

Follow the contour of the bottom mouth evenly for 6 ~ 7mm.

If it is made by hand, it can be separated from the inside and outside, with the widest area as the benchmark.

If it is a machine, the bottom of the front support must be the difference between inside and outside, because there is no "picking" process in the machine.

As shown in figure 1-3-25

Three quarter shoe design -- making shoe template.

The dashed line in the picture represents the outline of the basic template. The front end is lowered after 2mm, connecting the back midline of the shoe lining, the back end pressing stubble 8mm, and the bottom port receiving 6 ~ 7mm respectively according to the difference between the inside and outside.

The solid line is the shoe inside figure after the expansion.

After the design is completed, you can make a sample of the front shoe.

(2) the model of the front part of the three head shoes of the front part of the three section shoes is the same as that of the two front part, and the former Baotou and the former Chinese team need to be spliced together into a whole gang before designing the shoes.

Be careful not to divide the front team into two parts.

As shown in figure 1-3-26, the dashed line in the picture indicates that the former Baotou and the front middle team should be spliced into the front parts, and then the 2mm will be lowered at the front end to connect the middle line of the shoe back.

The shoe mouth contour adds the 8mm stubble quantity, the bottom mouth receives 6 ~ 7mm, has the difference between the inside and outside bosom, finally takes out the shoe model.

If there is a difference in the length of the front, the design should be based on a longer upper.

(3) the design rule of the inner ear shoe in the front shoe of the front shoe is basically the same, but the shoe lining for the long front shoe is quite special.

Although the upper surface is long, the shoe is not necessarily lengthened, it can be disconnected from the waist socket, and the broken line is designed as a benchmark. The shoe is designed before and after the design, as shown in figure 1-3-27.

As shown in the figure, the front end of the 2mm is connected to the back midline, and the 8mm pressing amount is added to the shoe door, which moves along the downward line of the stubble line to form the broken line in the front part.

The bottom outlet is 6 ~ 7mm.

When you design the back door, add 8 ~ 9mm stubble before opening the door, then follow the broken line down to the bottom to maintain a distance of 8 to 9mm.

2. design in the later Gang

The front and back sides of the whole shoe lining are kept open, and are often used in shoe inserts with sleeves.

The inner ear shoe lining can be used in the two section structure or in the three segment structure.

There is no difference between the two segment and the front part of the three section shoe, mainly on the back.

If the back part is a whole block, it will form a two segment structure with the front part. If the back part is split into a heel part, it will form a three segment structure with the front part.

(1) the design of the two segment back Gang is the same as that of the two quarter head, or the three quarter head, or the back group.

The specific steps are as follows:

First, draw the contour line of the basic template, add the amount of 3mm to the shoe ears and the shoes; add 8 to 9mm of the stubble at the front of the shoe ears; receive the 2mm at the back arc Q. point at the D point, enter the 3mm, return to 5mm at the B point, and then connect the three points into the rear arc of the shoe.

The bottom mouth is based on Li Huai, and receives 6 ~ 7mm.

The shoe in the back can not be handled separately.

As shown in figure 1-3-28

The dotted line is the outline of the basic template, containing the largest rear area.

Add the amount of 3mm flush on the shoe and connect the rear arc to the new rear arc after receiving 2mm, 3mm and 5mm. The bottom port is collected 6 to 7mm, and the front end is pressed stubble 8mm.

Finally, draw the shoe template according to the solid line.

For the shoe with the back pack, although the upper point of the upper shoe has been collected from 1.5 to 2mm, the shoe lining is still in the inner circle of the helping surface, so the shoe still needs to shrink 2mm.

(2) the design of the three segment back group is evolved from the two part of the back Gang, which is divided into two parts: the shoe ears, the heel, the back and back, and the inside and the back.

The specific steps are as follows:

First, draw the contour line of the basic template; add the amount of 3mm to the shoe ears and shoes; add 8 to 9mm of the stubble at the front of the shoe ear; place the 2mm position at the back arc's QQ, and connect the middle line of the rear package with the position of the D receiving 3mm, and the lower end is connected to the B point of receiving 5mm; the bottom port takes the Huai Huai as the benchmark and receives 6 to 7mm.

Finally, in the narrowest position of the shoe ear, make a split line for the back pack and leave the 4 to 5mm small stubble quantity in the shoe ear dividing line position. This is the outline of the shoe ears, and the rest is the contour line of the heel.

As shown in figure 1-3-29, the dashed line is the basic template for the inner heels, the solid line is the outline of the shoe, divided into the shoe ears and the heels, and the heel is the pattern plate after the expansion.

(3) the design of the front part of the long front shoes is special because of the special front shoes in the front shoes.

When designing the two section back, you should first find the location of the front line in the front, then add the amount of processing according to the contour of the back.

As shown in figure 1-3-30, add 8 to 9mm of stubble before the ear, then maintain a certain distance from the front line, extend it to the bottom, and control the distance between the bottom line and the two line from 8 to 9mm.

When designing the long front shoe three section back, the other design rules remain unchanged, but only to design the position of the break and the rear midline.

As shown in figure 1-3-31

This is to cut out the back package and the components in the two section back.

In the position of about 40mm long, and the length of the bottom port about 60mm, the break line is designed, and the 4 ~ 5mm small stubble quantity is added to the components in the heel.

Connect the 2mm of the back arc and the 3mm position to the middle line, that is, the outline of the heel.

Through the study of this section, we can know that the structural design can accurately represent the structure, shape and contour of the upper part, creating a good condition for the board.

Before you hit the board, you need to convert the structural drawing into a scribing board. With the marking board, you can make the basic template, the material sample and the shoe template.
