Design Of Non Wrinkled Bottom Shoes

The general fake bag bottom shoes, half bag bottom shoes and all bag bottom shoes are wrinkled in the cover, and the wrinkle bottom shoe is obviously a special case.

If the length of the shoe is short, the wrinkles will become wrinkled. If the length of the fence is equal to the length of the cover, the wrinkles will be eliminated. This is the main point of designing the wrinkle free bottom shoes.

1. finished product drawing

As shown in figure 2-5-29, from the appearance it is a shallow round shoe, which is easy to achieve wrinkle elimination because of its narrow and wrinkled features.

There are no wrinkles in the toe of shoes, and cross stitching is also adopted.

2. structure design drawing

First, design the foundation structure according to the design method of shallow enclosure shoes.

As shown in figure 2-5-30, there is no need for tension, but the exact difference between inside and outside is to be made.

Design the punch position on the shoe cover and the back strip.

3. make the basic model of shoe cover.

As shown in figure 2-5-31, press the stubble quantity on the shoe cover, double row holes and row spacing 3mm.

4. make the basic template of the enclosure.

As shown in figure 2-5-32, take the model of Wai Wai Wai, mark the boundary with no wrinkles and punch holes for the back.

5. design of shoe structure

The structure of the shoe is designed by using a boilerplate as a copy board, as shown in figure 2-5-33.

First, the A1 point of the A1 shoe sole is aligned at the boundary of the outer side of the shoe, and the back edge is placed on the edge line of the sole to find the tangent point B1, then the length of the rear arc is b1B=b1B1.

If there is any error, move the contour template to ensure that the length of the backing is unchanged.

After finishing the rear arc length, draw the contour line of the back section and pfer the punch marks to the same contour line.

We will find that there is a gap between the fence and the sole. We use figure 2-5-20 to pfer the size and position of the voids to the bottom line.

Pay attention to the amount of difference between the inside and outside.

The contour line of the front part is still used the wheel rotation method to trace the contour lines of the Wai Wai Wai separately.

Because the length of the contour of the shoe body is larger than that of the shoe cover, wrinkle elimination is necessary.

First find the difference between the girth and the shoe cover.

For example, 148-116=32 (mm).

When the shoe is connected, the shoe cover is in the inner diameter of the curved arc, the outer section is in the outer diameter of the curved arc, and the outer section can have an increase of 0.5 to LMM.

A total of 20 shoe holes, can increase 10~20mm, then wrinkle volume is: 32- (10~20) =12 ~ 22 (mm).

The wrinkle volume of the Huai side is different from that of Huai Huai, and it can also be calculated.

Mark the wrinkle volume on the design chart of shoe structure.

The bottom line of the picture has a "Y" - shaped opening at the end of the toe A1, and a straight line with a 45 degree angle at the bottom midline.

Taking the straight line as the center, the size of the wrinkle is cut off and the position of the sole is connected to the strip, which is the amount to be eliminated.

As shown in the shadow.

6. make the basic model of shoes.

As shown in figure 2-5-34.

This is the basic model of shoes. How do you crease it?

First cut the template along the bottom line, the waist of the shoe has a difference between the inside and outside, and cut to the Y shape.

Then the template is opened to make the toe part overlap, and the amount of overlap is the size of wrinkle elimination.

Draw the template in this state, that is, wrinkle free pattern.

The shoe toe part is treated by arc. See figure 2-5-35.

Use the wrinkle proof template to open and drill, the sole part is used to sew the seam machine, and the back arc parts are stitched together. The bottom seam of the back arc is locked to form the lower part of the shoe.

And then sew with the shoe cover, that is, the completion of the upper.

The bottom shoe is a variant of the cover shoe. It is easier to learn the bottom shoe after learning the design points of the cover shoe.
