First, the basic structure of leather shoes
(1) Upper: the general term for the overall external parts of shoes. Gfxin.zx98.com comprises a shoe liner, a front upper side, a shoe tongue, a horizontal liner, an inner and outer part of a middle upper, a back cover, a shoe mouth bead and an elastic band.
1. Shoe bladder:
The right upper part of a shoe (i.e. the instep part of a person) is the most conspicuous part of the upper part. Generally, the high-quality leather and style changes are reflected by the shoe bladder when making.
2. Sideways of the front upper:
It is located on both sides of the shoe bladder, which is divided into the inner side and the outer side. Its bottom is glued to the sole, and the upper part is connected with the shoe bladder, which wraps the front sides of the human foot. It bears the maximum extrusion force given by the human body, so it is the part that can best reflect the comfort of shoes and is also the part that is most prone to quality problems.
3. Shoe tongue:
The part connecting the shoe bladder is the part where the shoe bladder extends to the back of a person's foot. The function of the shoe tongue is to cling to the back of a person's foot on the one hand, so that it is not easy to fall off, and on the other hand, it plays the role of beautifying the upper. Whether the appearance lines of the shoe tongue are smooth and the shape is correct reflects the overall spirit of the shoe.
4. Transverse bladder: a transverse decorative belt located at the joint between the tongue and the bladder, which serves to:
block the joint between the bladder and the inclined body;
the style change of the horizontal gallbladder is the finishing touch for the shoes;
further tighten people's feet to prevent them from falling off.
5. Inside and outside waist position of the upper: it is located in the inner and outer foot sockets of human feet, which comfortably wraps the middle of human feet, connects the front upper, the back cover and the bottom, and plays a connecting role.
6. Back cover:
The part that wraps the heel of a person is made into an arc shape according to the shape of the heel of the person. On the one hand, it wraps the heel so that it is not easy to fall off, on the other hand, it cannot be wrapped too tightly to avoid "kicking".
1. 13 steps to make leather shoes.
2. Steps:
1. Make the laid leather samples into tinplate or plastic leather molds for the factories or processing shops specializing in leather laying, and the cutting master will use one of these two leather molds to cut materials. It is out of line in a narrow sense to be only responsible for the design and technology of uppers.
2. Cutting: The cutting master cuts the whole leather with a knife according to the put tinplate leather or plastic leather. After a pair of shoes are cut, they look like small pieces, not like shoes at all. In addition to opening the leather, the lining and cloth distribution of shoes are all completed in this process.
3. Folding surface: After receiving the skins from the cutting department, splice small pieces of skins with glue, and then tighten them with a wooden hammer or hammer as required. When finished, the whole vamp is almost a whole piece.
4. Shoveling: After receiving the product with good folding surface, in order to prepare to install the upper on the sole, the joint between the leather and the sole must be thinned with a spatula to make the joint more firm and beautiful. This process is completed by manual operation of the machine, and whether the whole pair of shoes is easy to open in the future is very important. Although the machine is operated by people, the quality of products is determined by people's operation technology and skilled procedures.
5. Car surface: Turn small pieces of shoes with folded surfaces and good leather into one piece. The car surface is also a key process. Whether the car is beautiful, whether the parking space and needle position are in place determines the beauty and durability of the shoes.
6. Fierce shoes: Put the finished vamp leather on the shoe last, and then nail it on the edge of the vamp leather with spikes to fix it on the shoe last. The shape of the vamp is generally determined by this process, whether it is smooth, whether it is straight after putting on the feet, and whether it is crooked or not is often determined by this process.
7. Bottom drop: Fix the hardened vamp together with the last head on the sole, then clean the joint between the sole and leather with cleaning liquid, blow dry, and then fix it with glue.
8. Molding: Put the shoes with good soles on the molding machine to make the glue stick to the bottom better, and then the leather will be more stable and will not be deformed after molding. Painting: Many shoes need painting. After painting, especially the black color will be more beautiful, deeper and darker.
9. Drying: Put the painted leather shoes into the oven for drying. Generally, the drying equipment is strong light, just like the lamp of Yuba for washing and drying, but there are many. There are also heating wires for drying, but the heating wires radiate unevenly, and the heat absorption efficiency of shoes is not high.
1. Polishing: This is the most critical process in the back of shoes. Polishing determines whether the color of shoes meets the requirements of customers. Polishing is divided into polishing and charring, and waxing and other treatments are all in polishing.
11. Laser: Many shoes need to be engraved with some patterns, or trademarks, patterns and the like on the leather and the inside of the shoes. Laser burning looks very high-grade.
12. Typing: gold paper or tin foil is used on the foot pad or the inner waist of shoes, and a mold with patterns or characters is installed with a heater. After heating, gold or bank is pressed on the foot pad or the inner waist.
13. Packaging: Actually, it is also very important, because the shoes have been formed. It is necessary to ensure that the shape of the shoes remains as original as possible after leaving the factory, and to keep the shoes from being damp and moldy. These depend on packaging. The most important process of packaging is to make a special O-shape with toe cap paper through special folding, and then insert it into the toe cap to ensure that the toe cap remains unchanged. Toe paper is composed of single copy paper or double copy paper wrapped outside the toe paper. The toe paper inside has the functions of shaping and absorbing moisture. Then put it into a shoe box or various accessories to make a good pair of shoes. It is important to grasp every step and detail.
