If the function is divided into three types, there are natural stilts, craft seesaw and changeover.

If we use the technique of taking off, we call it too many names. Because of the experience of individuals, many of them are repeated naming. We can refer to various experience designs.

1. natural stilts

Natural stilts are ubiquitous.

At the back of the last place, it is a saddle shaped curved surface, which has the curvature of the front and the back, and the bending blue degree of the left and right.

For example, when using a flat paper to paste a last piece, it can not be attached to a flat.

If a pverse cut is made on the paper, the problem is simple. Because the saddle shape integrity is damaged, the saddle shape is divided into two parts, and the bending direction of each part is generally unidirectional, which is easier to bend over.

The angle formed by the scissors is natural.

If we use the pattern paper to paste the last, if we want to flatten the half panel, there must be a scissors opening in the part, but the angle is a overlapping angle after leveling. This is also a natural stilt.

Natural stilts can be represented by "VOV", as shown in Figure 0-2.

Natural stilts refer to the naturally generated stilts in the back midline of the last step during flat or flat surface restoration.

The last surface flattening is curved to plane.

In the pformation process, the reconstruction of flat surface is the pformation process from plane to curved surface.

The function of the natural stilts is to solve the integral half of the half panel.

The half panel is a flat panel. If a natural seesaw is added to the half panel,

The half panel will become a curved surface, and it will fit on the last surface with the curvature of the last surface.

Similarly, the last surface should be displayed in a normal way.

At last, the last surface is pformed into a half panel with similar size and similar shape.

The size of the natural stilts is directly affected by the curvature of the last curved surface. The shape of the flat saddle and the saddle surface of the high heel last is different from that of the natural one.

Same.

For the same shoe last, the size of the seesaw angle varies with the different measurement methods, but the natural body size of the last body is invariable.

Therefore, in order to get more accurate natural stilts, we must standardize the operation process.

For example, there is a natural stilt between the front and back sides of the two head shoes, no matter what kind of design method is adopted.

It must be sew.

If this angle is large, or this angle is small, it will directly affect the effect of the bandage: if this angle is gone, the problem will be.

Large, will cause no last.

So if we have a full understanding of natural stilts and take a natural sedan directly, the problem will be solved.

There are often some designers who try to flatten the natural corner when preparing half panels. Although the model looks smooth, it checks the gate.

The natural link of the key is lost, which will cause the template to last.

We have to try it out, try it once, change it once, and then change it until we look for it.

Back to the lost stilts.

This is obviously not a technical problem, but an understanding problem.

Can not use natural stilts, so there is no problem of last.

If we understand the principle of taking off, no matter how to design the template, we should be accurate.

Two

Craft sew.

Technological sedan refers to the local seesaw angle processed by technological means.

For example, there will be several cuts at the bottom of the front and rear heel, and the back end of the shoe.

If you don't stick to the last, the usual method is to trim a circle angle on the back of the template and the arc. The female's round mouth shoe does not stick to the last one, and it will play a cut in the template.

A corner is inserted into the mouth; the bottom of the enclosure is too large, and the usual method is to cut off a corner at the front edge of the fence.

These treated shears or seesaw degrees.

All corners belong to the technological seesaw area.

There is a common feature in dealing with these angles, which is to solve the problem by modifying the local model.

The effect of the technological stilts is to solve the local bending last part of the model, as shown in Figure 0-3.

As shown in the figure, the waist waist shoe of the female shallow shoe is not attached to the last shoe, it can be partially processed in the waist. The shadow in the picture indicates the increased process.

The dotted line indicates the position of the rear group after the stilts.

Similarly, when making the whole package, if the upper part is not stuck to the last part, it can also be handled locally.

The position of the technological sewer is relatively scattered, mainly distributed in the front, heel, waist waist and other positions of the last, which is related to the convex concave of the last surface.

Last surface

It is often necessary to use technological steps to achieve the goal of local die last.

The handle of the craft is flexible, with the location of the components.

Different ways of handling will also be different, sometimes adding a stilt, sometimes reducing a stilt, to be determined by the specific location and the last effect.

For example, there is a craft sedan between the three front shoes and the former Baotou.

The early Baotou model was directly segmented from the front of the two section.

As it is intercepted, it is necessary to add a technological stilt by modifying the template because it does not stick to the last. Therefore, the three head shoe is easier to hold the last shoe than the two head shoe.

In structure

In the design, as a result of the existence of half panels, as long as the required location and requirements for the preparation of the former Baotou model, it will naturally have a technological sedan, as shown in Figure 0-4.

As shown in the figure, Baotou is the same as the middle back line in the graph (a). If you want to better hold the last one, you must take the technological sedan.

(b)

It shows that there is an angular difference between Baotou and the central line of the gang.

Figure (c) is to design Baotou parts on half panels, because the back midline is a piece of music.

The line will make natural difference between Baotou and the middle side of the gang, so that it has the function of technological seesaw.

Three

Conversion sew

Changeover refers to the seesaw angle that occurs when the midline of the front and back is converted into a straight line.

Changeover belongs to a special type of stilts, which is artificially added.

Entrance.

For example, when designing tongue shaped shoes, whole tongue shoe and whole tongue type shoes, you need to deal with the back midline of the front and the back midline of the back.

A straight line is formed. If only the natural stilts are added, the back midline of the half panel is still not a straight line.

This additional angle is called changeover, as shown in Figure 0-5.

As shown in the figure, the figure (a) represents a whole tongue shoe. The back midline of the front and back is not a straight line, and can not be directly taken from the board. B (Figure) shows that

It is still not a straight line to restore the natural back.

(c)

That is to add a changeover (shadow).

Straighten the midline, but the front Gang becomes longer.

Figure (d) is to pform the Seaway schematic diagram, and eliminate the negative effects brought by changeover by manual way.

Changeover is not the seesaw required for the last surface. It is only for the middle of the back line that it is added directly.

The back midline that does not join the switch is curved.

It is impossible to prepare the whole front support; after adding the switch, the back midline can straighten, but it will cause the midline to lengthen.

If this lengthened quantity remains

The bottom of the mouth will increase the amount of tension. If it stays between the covers, the cover will be misplaced, so it must be repaired.

So the particularity of changeover is in the forehead.

The amount of external increase should be removed. This obviously brings trouble to the handling of sedan.
