Model Design Of Baozi Shoes

　　 Loafer shoes It is also known as burning wheat shoes, bottled shoes, dumpling shoes and so on. This kind of shoes is wrapped up with a whole leather material (bottom wrapping strip) from the bottom of the bottom of the last piece and is sutured with a piece of leather (cover) above. When the upper and lower two pieces of leather are stitched, some uniform wrinkles appear on the sides and the cover of the cover, and the appearance is very similar to that of the steamed stuffed buns. It is usually designed as a cover type.

The characteristics of baozi shoes are: hand and sewn covers and hand wrinkles, without inner Baotou and flat heel design. It is a common style of men's and women's casual shoes. It is soft and comfortable to wear, especially when the front sole is covered with leather, and its softness and hygienic performance are good. However, this type of leather shoes will be linked to the bottom as the whole structure because of the bottom wrap round, and no inner Baotou. Therefore, the front tip and the outer side of the leather are easy to be warped up, and the stereotypes are not ideal.

Men's wrinkled steamed buns shoes

Because the design of the steamed stuffed bun shoe is a cover type, its last shape is similar to that of the ordinary cover. The shoe last is characterized by a thick and thin head, a round shape, and a sharp edge on the last side, but not a real line.

A package of bottom covers Template design

(1) model design of Wai bar

According to the design method of the ordinary cover leather shoes, we design the template of the cover, the long fence, the shoe tongue, the rear package and the cross bar. Among them, the long gird pattern is not processed, and the latter is processed with the sample.

On the long gird template, mark the control point of the wrinkle (usually Q y), and make a straight line from the point to the bottom edge line, the intersection point is M 1. The required straight line should be perpendicular to the broken line of the cover pattern and mark the intersection point on the bottom edge line. At the same time, mark the N 1, which is the position at the back end of the long edge, along the bottom edge line.

(two) Insole Template design

(three) design and manufacture of the sample plate for the bottom of the package

1. in a contour line between the inside and outside ankle door points of the surrounding template, that is, between the two wrinkle control points of the medial and lateral malleolus, the cutting edges are evenly cut.

Cut depth control: the depth of cut should be the width of the location. The curvature of the front edge of the fence is larger, the depth of the cut should be larger, the control should be in; the rear end of the enclosure is smaller in curvature, and the cutting depth should be smaller.

Cutting density control: the cutting density is generally 5~10, the radius of the front edge of the fence is larger, the cutting density should be larger, it should be controlled at 5~8, the rear end of the enclosure should be smaller, the cutting density should be smaller, and the control should be 8~10.

2., we will open the pattern of the long gird with a cut, so that the edges of the bottom edge will coincide with the inner bottom template along the contour line. At the same time, the two control points should be overlapped with each other.

3. measuring the length of the contour line of the wrinkles, and calculating the amount of the corresponding part increased. The amount of increase required should be basically equal to the amount of wrinkles in the surrounding bars. If there is any error, it should be controlled within 6.

4. first overlap the point of the wrinkle control point with the inner bottom template, then make the coincidence point move backward and gradually draw the outline of the second part of the long fence. At the end of the end, draw the wrap line, and the corresponding points on the template should be rearranged.

Repeat the same operation to draw the outline of the rear part of the medial ankle.

5. the position of the heel line is determined on the template on the bottom. The center is taken as the center line, and the 15 sides of each side are taken as two parallel lines. The front end of the cut-off strip is wrinkled at the control line, and is processed in an arc shape, and the rear end to the heel line. Inside the quadrilateral, there is no leather wrap, it is the part where the hook is assembled, and it is also convenient for the last process.

Two design of crease and wrinkle for enclosure and cover

There are usually two kinds of methods for raising the stem of the steamed stuffed bun and the cover, one is the side of the cover and the other is the seam, and the other is the circumference of the cover of the blanket. The two is the enclosure.

The formation of the wrinkles of the girth: since the girth and the cover are manually stitched, the same number of holes are placed on the cover and the surround before the stitching. If the length of the girth is larger than the length of the cover, the average amount of the larger volume is divided into the spacing between each hole, so that the spacing between the holes of the round hole is larger than the distance between the holes of the cover hole, so that after the stitching, a uniform wrinkle is formed between each hole.

(1) the method for raising the stem of the enclosure and the cover.

1. pairs of slots

For the sake of refreshing and neat appearance, the surround cover is usually rolled to the side and then seams with the surrounding bar. In order to prevent the stubble from exposing too much, the margin of the eye position of the cover is slightly larger than the margin of the eye position when the hole position is determined. Besides, the edge of the cover is further increased, so the stubble after the suture is bound to be hidden.

In general, the processing allowance should be 2~3, and the processing allowance should be 3.5 to 4.5.

2. bags sew up

The processing method is to wrap the edge of the fence with the cover and then stitch it by hand.

Therefore, there should be a row of holes in the enclosure. There should be two rows of holes in the cover.

In general, the margin of the hole is designed from 2.5 to 3, and the margin of the first row of the cover is designed to be 1.5. Therefore, the margin of the second rows of holes should be calculated by the following formula:

The distance between the second rows of holes in the cover is the margin of the first row of holes on the top of the cover. +2 * the margin of the circumference is + =1.5, +2, 2.5 to 3, +2.5, =9, 10.

In actual use, considering the influence of wrinkling and the thickness of the lining, the amount of the outer casing should be increased by 2~3. Therefore, when the processing allowance is 2.5 to 3 +2, the allowance for machining the cover should be 9~10 to 3.

(two) method of wrinkling around the strip

1. determine the spacing and number of holes on the cover.

(1) starting from the center point of the front cover, the distance between 4 points is to determine an eye position until the wrinkle control point at the entrance.

(2) determine the number of holes in the medial and lateral ankle contours respectively. The number of lateral malleolus eyes is 1~2 more than that of the medial malleolus, and the total number of holes around the lid is about 54~60. The average number of holes in the inner and lateral malleolus is 26~30.

2. determine the spacing and number of holes on the fence.

(1) the distance between the holes of the surrounding bars should be increased by 2 times than the distance between the holes of the cover holes. After the suture, the amount of the increase will form wrinkles, so the spacing between the holes of the girth should be 6.

(2) the number of holes on the fence should be the same as the number of holes on the cover. Moreover, the number of holes in the lateral malleolus is strictly corresponding to the number of holes in the lateral malleolus, and the number of holes in the medial malleolus is closely related to the number of holes in the medial malleolus.

(3) in fact, it can also calculate the theoretical data of the distance between the holes of the girth and the distance between the holes of the cover and the hole according to the growth of the girth obtained from the front panel of the bottom wrap around the front. However, considering the influence of the material performance, the actual data of the spacing between the holes of the enclosure and the enclosure can be determined. In general, the data obtained are basically the same as those of the first one. If there is any error, the transfer should be adjusted to ensure good performance.
