Half Panel Features Of Women'S Shallow Shoes

The design of female shallow shoes also needs to prepare half panels.

The biggest feature of the half panel of the female shallow shoe is that the handle is directly disposed on the half panel without recording the amount of sigma, eliminating the trouble of locating, aligning and switching.

First, we need to prepare the original template and then process the original template into a half panel.

The method of preparing the original template is unchanged. Please refer to the first chapter.

The key to tackle the problem is the flatten process of the last surface.

The main operating requirements for post last are as follows:

1. pfer point

Transfer the commonly used design points to the last paper, including V, V, E, Q, C, D, P, F, H, J and so on.

Pay attention to the E point to take 27% of the foot length, which is used to design the shoelace.

2. last surface flatting

First remove the last piece of paper, make 2~3 cuts at the bottom of the front tip and the bottom of the heel, and place 1~2 cuts in the position after the middle line V point.

Then paste the last paper onto the pattern paper.

The procedures are as follows:

(L) first stick the shoe line OQ to make the shoe line smooth and not wrinkle.

(2) paste the rear arc Q > 0 to D to B, and do not change the length of the rear arc.

(3) proceed from 0 point, and put the front part flat in the middle position of the front team and toward the J point. This step is the key operation to decide the model.

(4) then place the rest of the body flat.

When cutting back the middle line, it is not necessary to record the amount of cut.

3. prepare the original template.

Cut out the outline of the last board to get the original template, and check the original template.

The method of inspection is to set the sample for the last test.

The specific procedures are as follows:

(1) draw the outline line of the original template on the kraft paper, connect the VH line to the front control line, take the VH line's 1:/2 fixed O point, connect the OQ line to make the back height control line.

(2) connect VJ to the back midline and extend it to Ao point and draw a simple round shoe outline in the range of V to O to Q.

(3) trimming the middle line and cutting out the template along the contour line of the periphery, that is to say, the set with the outer arms as the benchmark.

(4) stick the rear arc to the top and carry out the test.

The set is made of paper to make shoes, and the accuracy of the original template is tested.

The original template is the basis for designing the half panel of women's shallow shoes. If the original template is accurate, the half panel, the base template, the opening plate and the inner template can be accurately located. If the original template is not accurate, the operation behind it will not be smooth, and it will always be patched up and added to much trouble.

The paper cover test can save time, labor and save materials, and it is also accurate.

Because the shoes made of paper can not be stretched arbitrarily, if a part of the problem is immediately reflected, the problem can be eliminated before design.

If the leather is used as a binding test, the extension of the material will obscure the problem, which will affect the accuracy of the design.

4. sample inspection

The test is done with shoe covers made of paper. The contents are as follows:

(1) the inspection of the shoe line is to wrap the paper shoes on the shoe last. The V points are aligned and the Q. points are highly aligned. First check the shoe line.

The shoe line can be naturally attached to the last surface.

If the shoe line is on both sides or side, it does not stick to the last.

At this time, the height of the paper shoe set can be adjusted.

If the QD moves down, it can be attached to the last one.

(2) the length of the test points the Vo points together, the length of the midline can be observed, and the length of the heel arc can be observed after aligning the q.

The length error should not exceed 0. 5mm.

For the length of the shoe inside and outside, it is also necessary to test the length.

When the point is highly aligned, its position is not necessarily located on the rear arc midline.

Re adjust the Vo point, paste the flat shoe, so that the QQ drops down naturally, and observe the relationship between the QQ and the rear arc midline.

In general, the Q. point will move to the side.

Because the length of the shoe upper is equal inside and outside the model, indicating that the last surface of the bosom is longer, resulting in the movement of Q.

If the shoe is in such a condition, it will be called a posterior seam.

If you want to use the external force to twist the back seam, it will cause the distortion of the door.

In the treatment of posterior seam, women's shallow shoes are quite different from those of full shoes.

The way to solve the problem of incomplete seam seam of women's shallow shoes is to deal with them separately.

First, measure the difference of the length of the back seam, that is, the distance between the point and the middle line of the back arc.

Then the l/2A is added to Li Huai, and the l/2A is reduced to the outer arms. The total length is kept unchanged, and the location of QQ is adjusted locally.

This method of processing length is divided into two parts.

The general delta quantity is between 2 and 3mm, and it can reach 5 to 6mm when it is special.

If it is below Imm, it can be ignored.

If it is found that the length of the bosom is longer than the outer one, it is an anomaly. First, check the location of the midline.

Because the 1mm error of the midline will cause the error of 2mm of the back length.

(3) the width of the inspection should be segmented.

The front part: Vo point and back line alignment, observe the bottom of the last two sides of the mouth.

The general situation is that the model is beyond the bottom, which indicates that the last face of the front part of the heart is narrower than the outer one.

Record the size and location of the difference. This is the basis for the difference between the inside and outside of the forehand.

In general, the loss is reduced to 2 to 3mm, and it will increase or equal in special circumstances.

Middle segment: keep the front and back sides tight and observe the bottom of the waist.

The general situation is that the model is on the last surface. Record the size and location of the loss. This is the basis for the difference between the bottom and the waist.

The difference between the inside and outside is bigger. With the difference of height, there will be 3 ~ 4mm, 5 ~ 7mm, 8 ~ lOmm and so on. Generally, the higher the heel is, the greater the difference.

Posterior segment: under normal circumstances, the bottom of the heel is approximately equal.

(4) specific problems should be analyzed in the inspection of waist and socket craft seesaw.

Wrap up the paper upper and smoothen the waist side.

If the shoe is not deformed, if it can be basically smoothed, it can be done without the waist.

This phenomenon is mostly on flat last.

If the shoe is flanking, or the shoe is torn or can not be smoothed under the smoothed condition, it is necessary to add the waist socket craft sedan.

This phenomenon is mostly found in middle and high heels.

How big is the waist socket craft?

How much do you need to add?

You can make a cut in the waist area of the set, cut the length close to the shoe line, but do not cut it.

Then the flat sample is set to observe the cutting amount of the cut on the last bottom line. The size of the cut is the size of the waist socket craft handle. Remember to do sigma y.

Do not take feet when taking the technological sedan. Take (1/3 to 1/2) Sigma y.

5. preparation of female half shoe half panels

It is a few essential steps to paste the past, find the point, prepare the original template and set the sample, especially the original template must be accurate.

If the original template is not accurate, please adjust the accuracy and proceed to the next step.

The half panels of women's shallow shoes are relatively simple. Most of the contour lines do not move. They only need to deal with the heel arc.

Taking into account the accuracy of shoe sticking to the last, it is necessary to receive 2mm at the QQ location. Considering the main capacity, it is necessary to increase 1mm at D point and increase 2mm at the correct [B] point.

The [B] point refers to the position after eliminating the influence of the shear quantity.

Qpoint -2mm, D point +lmm and [B] point +2mm are general laws. If conditions are special, they should be adjusted appropriately.

The width of the mouth door of women's shallow door shoes is different from that of the inside and outside, and the size of the difference can be measured from the last surface.

For the convenience of application, you can connect the VHi line of the front control line on the side of the Huai side. Also take 1/2VH, line the O'point, then connect the O'Q line to the rear height control line, see figure 3-1-1.

The VH line and the VoH1 line are the front control lines of the outer Huai and Li Huai, respectively. The OQ line and the O'Q line are the height control lines of the outside and the Huai Huai Huai Huai respectively.

In this way, there is a basis for designing the difference between the inside and outside contour of the door.
