The middle and rear gang has aroused the enthusiasm of many people for fighting. After a period of fighting, no matter what you promised at the beginning, you will eventually end up with a pile of broken iron. The middle and rear gang undoubtedly gave the entire shoe industry a heavy blow. class. Counting down the reasons, it is not the crime of the middle and back gangs, and everyone has not seriously thought about the disadvantages and responded forcefully.


In fact, the emergence of middle and rear help machines eliminates the need for waist help operators in factories that use them well, shortens the process, and improves efficiency. It is a great thing. Unfortunately, many people did not take it seriously, which led to a lot of criticism of it. .

Any machine has its limitations. It cannot be assumed that one machine can solve all shoe shapes or difficulties. For people selling machines, unfounded bragging will end up hurting themselves, and the middle and rear gangs are of course no exception. Some people say that you can make 12m high heels, can you do it? It depends on the requirements of the shoes, some people can accept it, some people simply can't accept it. Of course, to make good use of the middle and rear gang, we must first clear the following obstacles:



1. The front helper that cooperates with it. The previous process was to use a waist machine or manually pull the waist after the front, because the waist (especially the inner waist of women's shoes) has curvature and depth, and the last must be pasted. Now, after the front gang is over, go directly to the middle and back gang, which requires a good connection. First of all, when choosing, try to match the middle and rear upper as much as possible. The front upper must be selected for the fourth claw, which can be rotated inward, and has a clasp and auxiliary small wiper. These configurations are helpful for some special shoes. The gluing method of the middle and rear gang should be unified, either all rubbing glue, or a uniform hot melt glue. Many middle and rear helpers are not used well, because the glue is not uniform with the front helper, and the cohesion is not good.

2. The layout position must be adjusted accordingly. The traditional process does not have high requirements for the corner position of the help. When pulling the upper by hand, part of the waist is usually opened, and the waist shoes face to the toe and pull backwards. The waist can be directly pulled down, so that there is no waist position. Wrinkles, and the middle and back gangs do not have the hand-pull link, they must be solved by other means. As mentioned above, the inward rotation of the fourth claw of the front helper is to solve the problem of pulling to the toe, and the backward pulling and waist pulling must be solved by the layout position! The position cannot be large, and it should be lightly placed on the shoe On the last, the upper corners should be in the shape of an inner figure toward the middle of the last, so that the middle and back uppers will not be cornered when they are tied together, which is very smooth. When designing the upper, it can be considered that the sewing position is just at the junction of the front and middle and rear uppers, and even an artificial transfer point is created to facilitate the end of the front and the opening of the middle and rear. Italy's top outdoor shoe SCARPA is here A small piece of vamp is deliberately left at the junction of the front and middle and rear sides for clamping by the fourth jaw of the front machine and the clamping jaws of the middle and rear sides.





3. Requirements for finalization. In the use of the middle and rear side, it is often seen that the water port is not completely shaped. The inner, the port and the upper must be shaped by the heel to make them stick together. Otherwise, the jaws of the middle and rear side cannot be completely clamped. Tight, leading to unsatisfactory lasting, the waist must also be properly sprayed with glue to prevent the vamp from delamination with other parts. At the same time, when the heel is finalized, the customized mold must make the corners of the finalized corners into the shape of the inner horoscope, so that the ties are more smooth.





As long as we hold a scientific attitude and deal with the above obstacles in a realistic manner, the middle and back gangs will definitely be able to glow with their due light.
