Design Of Open Mid Seam Shoes -- Design Features

The general design of the upper shoe requires that the back midline of the front part keep on opening, and the left and right parts become a whole, which makes people look comfortable. Even if half panel is used for design, it is necessary to take two folded plates to maintain the integrity of the components. Open the middle seam shoes but do the opposite way, using the middle seam as decoration, can be said to be an alternative to shoes, although there are not many products in the market, but the products are very distinctive.

Open mid seam shoe is a type of shoe that is longitudinally disconnected in the middle of the back. Because the back midline is broken, the model has good effect. It is often used in shoes that are difficult to handle, such as high heels, whole shoes, and boots. Sometimes, in order to save materials, or to highlight the visual effect of opening the middle seam, the middle opening structure is often adopted. See color H series. This is a group of shoes with mid seam structure.

The color picture H 1 is a family women's shoes that open the middle seam. The soft upper is very comfortable, and the heel can be worn as slippers. The middle seam is pressed by the stitching process. The front end of the toe is left with a pinhole after splitting, and the shoe is locked with rubber bands.

The color picture H-2 is a mid open seam shoe made of skin color. It has different color effects on the part of the protruding hole. There are two stitches in the middle of the shoe, one is the stitch after turning the seam, the other is the parallel line of the vehicle. The shoes are more avant-garde and rivets are used to reinforce the breakage positions. There is also a rivet at the upper end of the middle opening, which is the middle point of the upper.

The color picture H-3 is an early open mid seam shoe. The middle seam is sewn with a seam stitch. The shoe has a shoe shaped ear part extending from the inside of the shoe, and is connected with four buttons. As you can see from the picture, the shoe ears are connected with the inside and behind the arms, and cover the broken line. That is to say, the position of the broken arm inside and outside is different. The shoe mouth adopts the technology of the mouth, starting from the opening of the door, bypassing the shoe, until the position of the broken arm.

The color picture H-4 is a flanged casual shoe that is folded around the bottom and stitched. The main body of the middle opening is the open line stitching process, with its edge exposed and rough style. The front part of the middle seam is sewn by joint stitching, which is easy for the foot to wrap the inner bottom. The upper end of the middle seam is designed with two "saw bars" to play the role of locking and decoration.

The color picture H-5 is a formal shoe with dark and shiny leather with a touch of elegance and dignity. The middle seam is used to sew the seam with the seam. The position of the broken side of the outer side is decorated with saw blades. Because the position of the door of the shoe is at the back end of the middle opening, it is relatively backward, so we need to use rubber band to increase the opening and closing function.

1. characteristics of shoe last
The opening and closing structure is a kind of change in the form of break. There is no fixed requirement in choosing shoe last. It must be determined according to the style of shoes. If it belongs to the tongue type shoes, opening the middle seam structure, it is necessary to choose the tongue type last design; if it belongs to the ear shoe type and the open type shoe opening mid seam structure, we should choose the vegetarian head last design; if it belongs to the boot shoe middle opening structure, the female shallow shoe middle opening structure or the sandals open the middle seam, then we should use the high waist last, the female shallow mouth last and the sandal last to design respectively.

2. features of upper structure
The reason why the middle seam shoe belongs to a structural mode is that it is a special form of break. After the middle line of the upper is broken, the structural design is easy to obstruct, and the template is more convenient, and the effect of the last is better. Because in the design of the full length shoes, because the back of the last surface is a saddle shaped surface, the design sample is flat. To make the parts of the plane hang on the saddle shaped surface, it must be handled with a seesaw. The upper has a transverse structure, and the handle is smaller, so it is necessary to enter the position to take the stilts or the counterpart. Now the back midline of the upper is longitudinally disconnected, breaking the saddle shaped surface structure, so that the back line between the inside and outside of the shoe can be aligned with the back midline of the last face, so there is no need to locate, match, or switch.

Due to the natural stilts, the back midline and the last face of the half panel are not identical. When the half panel design of the full shoe is used to open the middle seam structure, the natural stilts need to be unfolded, so that the back midline of the half panel coincides with the last surface, so as to achieve the position of the counterpart line. However, it is not necessary to make a stilling angle. At this time, the stilling angle is only used to supplement the length, and the length of these millimeters can be completely achieved through the extension of the material. The operation of the half panel for making split seam shoes is as follows: see figure 1-9-1.

First, draw out the outline of half panel, mark common design points, basic control lines and take off corners.

Second, overlap the half panel and the outline line, fix the O point with the tapered cone, then rotate the half panel forward and below to make the OV line coincide with the OV line.

(3) trace the front midline and bottom line at this time.
At this time, the pattern of the sample is the half panel of the natural seesaw. According to the location of the front midline, it should be called a counterpoint seesaw. At this time, the half panel has restored the natural stilts, and the back midline and the last surface are identical. The bottom of the mouth does not need to be added to the stilts, because the back midline does not need to be converted, so the amount that is missing here is mainly that the length is shorter, and it can be solved by stretching the material without additional treatment.

Note: this half panel only applies to shoes with mid opening structure. If it is used for other full shoes, it must also be handled with a seesaw. In front of the design, the figure 1-7-21 of the open shoe has been used for the treatment of the front gear. The location of the door is more than V, and the saddle surface does not have any restraining effect. So women's shoes and sports shoes will have their own design templates.

Characteristics of 3. components
Because the middle opening structure is only a form of breaking, it can match the shoes of other structures. For example, open the middle seam outer ear type shoes, open the middle tongue tongue type shoes, open the middle opening before opening the shoes, open the side seam opening shoes.

4. characteristics of inlay connection
The upper seam of the upper is broken and needs to be spliced. Different forms of inserting have different characteristics.

(1) sew the seam together on the reverse side of the upper, then split it flat, and reverse the lining cloth. The lines appear to be stable.

(2) the pressure seam is similar to the treatment of the middle seam of the shoe back, and the double line open line is used to highlight the lines of the middle seam.

(3) on the front facing seam of the upper of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part, the vertical line is strong and cool.

(4) one side of the face is folded and the other side is folded. A parallel line is moved from the front side. The raised edges are seen on the appearance, the lines are embossed and the stitching strength is high.
Besides, some decoration can also be added after the above splicing.

5. modeling changes of opening and sewing shoes
The change of the shape of the middle seam shoe is mainly in the position of disconnection. With the different styles, there are some special changes.

(1) - the opening of the middle seam means that the position of the midline of the component is completely disconnected.

(2) in front of Baotou, opening the middle seam to enhance the sense of belonging of the toe ends, only break off a section of the former Baotou, and then open the seam on the open line. The saddle surface of this kind of shoe is not broken and can not be designed with counterfacet half panel.

(3) the front side opens the middle seam and opens the middle seam position in the front, and the saddle shaped bread is contained on the front side, then helps the back midline to continue to open, may use the alignment half panel design.
 
(4) the middle part of the part of the component has a middle seam. The breaking position of some shoes is only one section of the saddle shaped surface, and then stitched after breaking, which can increase the effect of the last bearing, but can not be designed with the counterfacet half panel.

(5) the middle and back joints are opened in the structure with the former Baotou, and the middle and the back sides can open the middle joints. Only the former Baotou keeps opening. Because saddle shaped surface is also damaged, it can be designed with counterfacet half panel.
Although there are different changes in the opening of the middle joint, the saddle shaped surface can be completely destroyed by the design of the half face panel.
