Design Of Cross Tongue Type False Cover Shoe

The cover and shoe cover of the cross tongue type fake cover shoes are kept open, without taking the technological stilts. Only the three factors affecting the location, shape and difference between the inside and outside of the cover can be noticed.

1. finished product graph analysis

As shown in figure 2-1-5, this is a pair of women's shoes with fake covers. The dividing position of the cover is to divide the surrounding strips and the shoe covers by using the fake line.

The design pattern is: pverse tongue type shoe structure design ten enclosure design.

 

(1) the basic structure of the structure is the same as that of the straight back and the back tongue.

The location of the cover is designed on the components.

(2) the last type is a female prime square square last.

(3) the components include five pieces of front, back, tongue, cross arm, and safety leather, six pieces.

(4) the front and back sides are pressed, the front shoe presses the shoe tongue, the cross arm is pressed on the break line, and the insurance skin is pressed on the back seam.

(5) the special requirement is that the shoe is a dark door structure, and the width of the door must be found at about OO'=lOmm.

When designing the false cover, it is necessary to pass through the last surface, determine the location of the Jt point, and then make the duplicate board inside and outside with the J'point as the front end point.

Because the replica board is suitable for the front part of the cover, the curve at the back end needs to be connected in sequence, as shown in figure 2-1-6.

 

 

As shown in the picture, the contour between the J'O'lines is inside and outside the shoe.

The procedures are as follows:

The first step is to connect the control line over the J point to the vertical line of the midline JV2 and take 1 / 2 of it as J.

Point, connect J.

0 line and 0 'line. This is the control line for the position of the enclosure.

The second step: design the contour line of the outer shoe cover, first position the front panel of the half panel at J'point, and follow the straight line JV2 to rotate the front cover shoe outline, and approximately to the half of the shoe cover.

Because the length of the replica board is not enough, the lines in the back section need to be drawn by hand, not necessarily through O points, but at 0..

The third step: in the design, the contour line of the shoe cover is determined on the contour line of the outer side, then the contour line is redesigned.

The method of design is the same as that of the outside.

It should be noted that some last sides of the last type are very different, and the complete copy of the sample is skew, so it is necessary to reduce the difference properly, and finally the appearance of the shoe last and the sample is all in harmony.

The difference between inside and outside is to beautify, and not to expose defects in order to make a difference.

2. structure design drawing

As shown in figure 2-1-7, take the location of the pick up, first find the front midline of the front, then design the outline of the shoe cover from the J'point.

Next, we design the other parts of the cross tongue shoe.

Because the tongue type shoes will be designed in the foundation structure, the surrounding covers will also be designed. Therefore, it is very easy to design the cross tongue type fake covers.

 

3. sample preparation

(1) prepare the drawing board as shown in figure 2-1-8.

 

(2) prepare the basic template as shown in figure 2-1-9.

 

There is a basic model of the shoe cover in the picture, whether it is the design of the genuine cover or the false cover, it is necessary to prepare the basic model of the shoe cover.

The fake line mark on the front Gang is drawn from the base of the shoe cover.

(3) draw the shoe template as shown in Figure 2 -1-10.

 

From the above diagram, we can see that there is no change in the method and rule of making the template.

If you design cross tongue men's shoes, the design steps are also the same as the design of women's shoes, but only to change the last shape and design style.
