2. Front side:
Located on both sides of the shoe bladder, it is divided into inner side and outer side. Its bottom is glued to the sole, and its upper part is connected with the shoe bag, wrapping the front side of the human foot.

1. Steps of making leather shoes *** 13.
Second, the steps:
1, put away the leather samples and make them into tinplate or plastic leather molds for special leather factories or processing shops. The cutting master will use one of these two leather molds to cut the material. It is out of line in a narrow sense to be only responsible for the design and technology of the upper.
2. Cutting: The cutting master cuts the whole leather with a knife according to the put tinplate or plastic leather. After a pair of shoes are cut, they look like small pieces, not like shoes at all. In addition to the leather, the lining and cloth of shoes are all completed in this process.
3. Folding: 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 leather and sole must be thinned with a scraper to make the joint more firm and beautiful. This process is completed by the manual operation of the machine, and it is very important whether the whole pair of shoes can be easily opened in the future. Although the machine is operated by people, the quality of products is determined by people's operating skills and skilled procedures.
5, car surface: turn a small piece of shoes with a folding surface and good leather into a piece. Automobile 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 upper leather on the last, then nail it on the edge of the upper leather with spikes and fix it on the 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 are often determined by this process.
7. Drop the bottom: fix the fierce gang together with the last head on the sole, then clean the joint between the sole and the leather with cleaning solution, 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, so that 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 to dry. Generally, the drying equipment is bright, just like the lamp used by Yuba for washing and drying, but there are many. There are also electric heating wires for drying, but the heat dissipation of the electric heating wires is uneven and the heat absorption efficiency of shoes is not high.
10, polishing: this is the most critical process of shoe back. Polishing determines whether the color of shoes meets the requirements of customers. Polishing is divided into polishing and carbonization, and waxing and other treatments are all in polishing.
1 1, laser: many shoes need to be engraved with some patterns on the leather and the inside of the shoes, or trademarks, patterns and the like, which look very high-end when burned by laser.
12. Typing: stick gold paper or tin foil on the mat or the inner waist of shoes, put a mold with patterns or characters on it with a heater, and then press gold or silver on the mat or the inner waist of shoes after heating.
13, packaging: actually, it is also very important, because the shoes have been formed, to ensure that the shoes are as original as possible after leaving the factory, but also to ensure that the shoes are not damp and moldy. These all depend on packaging. The most important process of packaging is to make a special O-shape with toe cap paper by special folding, and then insert the toe cap to ensure that the toe cap remains unchanged. Toe paper consists of single copy paper or double copy paper wrapped around toe paper. The toe paper inside has the functions of shaping and moisture absorption. Then put it into a shoe box or various accessories, and you can make a good pair of shoes. It is important to grasp every step and detail.
