We often hear about sewing machines of different specifications, such as Jeans Sewing Machine, but do you know the history of sewing machines? Hand sewing is an art form that is over 20,000 years old. The first sewing needles were made from bone or animal horn, and the first sutures were made from animal muscle. The iron needle was invented in the 14th century. The first sight of needles appeared in the 15th century.The Birth of Machine Sewing
The first possible patent related to mechanical sewing was a 1755 British patent issued to the Germans for a patent for a needle designed for the machine, but, if it existed, the patent did not describe the rest of the machine.
Several inventors tried to improve sewing
English inventor and cabinetmaker Thomas St received the first complete patent for a sewing machine in 1790. It's unclear whether Saint actually built a working prototype of his invention. The patent describes an awl that punches holes in leather and passes a needle through the holes. Subsequent duplication of Saint's invention based on his patent drawings would not work.
In 1810, the Germans invented an automatic machine for sewing hats. Krems did not patent his invention, but it never worked to good effect.
An Austrian tailor made several attempts to invent a sewing machine, which was patented in 1814. All his attempts were considered unsuccessful.
In 1804, Thomas Stone and James Henderson received a French patent for "a machine for imita

The digital punching machine is also called CNC Laser Pocket Opener. Its frame and machine tool are made of integral castings, which are stable and rigid. The transmission mechanism uses imported lead screws and the nuts are flexible and precise. The CNC leather punching machine adopts flexible tool control, and the tool can be rotated or not rotated according to needs. The self-developed processing software can switch the angle of the tool arbitrarily, and various special tools can process various patterns on the leather.Social development will also drive the development of other industries. For users, there are so many devices and different needs and different customizations. We have Special Industrial Machines for sale. You need to have a full understanding before using it. Of course, if you don’t understand it at the beginning, problems will easily occur in the subsequent use. If the user needs to use the punching machine, then you need to understand its attention points first. Let's take a look at the points for attention when using a punching machine.
When it is found that the position of the punching machine is shifted, it cannot be beaten with a machine or a hammer. Recommended air pressure: 5-7kg/㎝2. After use, first wipe the surface of the punching machine clean, especially the lower part of the punch head. Add lubricating oil to the punch and the lower die, and press the punch to a lower position so that the knife edge and the lower die are not damaged. T

The first step in maintenance is "cleaning", try to clean it once a day. If the daily maintenance of the sewing machine can be done well, dust and thread ends will not accumulate, and failures will not occur, and the machine can be used in a good condition. But did you know that you need to maintain your Shoes Sewing Machine? While cleaning the machine, some abnormalities can also be found. In the repair of machine failure accidents, most of the reasons are due to the accumulation of dust or thread ends.Not only must the sewing machine be cleaned cleanly, but abnormalities may also be found. For cleaning, maintenance is crucial.
Of course, it is not necessary to make the surface of the needle bar and the upper looper shaft completely free of oil. As long as the dust is removed, a light wipe is enough. For parts with complex shapes, use a used toothbrush to clean, and the dust can be easily removed. In addition, some sharp parts on the sewing machine should be very careful not to be injured during the cleaning process.
●Key parts of cleaning:
For sewing machines, like Garments Sewing Machine, not only do not make it break down, but also ensure the quality of sewing, there are 5 most important places. If these places can be cleaned thoroughly and cleanly, beautiful seams can be sewn. These places are cleaned in order, and it is recommended to clean them once a week.
1. Around the machine needle (wipe the needle bar);2. Cleaning around the rotary hook/looper;3.

The presser foot of the sewing machine plays a very important auxiliary role in the sewing process. The fabric can be fixed and moved on the machine through the cooperation of the feed dog of the presser foot. However, because the position of the presser foot device is different between brands, the presser feet of different brands cannot be called. Therefore, it is very necessary to master the use skills of each presser foot for proficiency in the use of sewing machines.The types of presser feet can be distinguished by material and use. Common presser foot materials are:
1. Metal presser foot
Metal feet are most commonly found on sewing equipment. The metal presser foot is durable, wear-resistant, widely applicable, and not easy to deform. The metal presser foot is mostly made of all steel, with chrome-plated and nickel-plated surfaces. The chrome-plated presser foot has a brighter luster and wear resistance, while the surface of the nickel-plated presser foot is duller and anti-oxidant.
2. Resin presser foot
Resin presser feet are widely used on sewing machines in recent years because of their low pressure on fabrics and high friction between the surface and fabrics, making them difficult to slip. They are especially useful for sewing light, smooth, coated and leather fabrics. obvious advantage. The main advantage of the resin presser foot is uniform feeding, low pressure and no tooth marks. However, the service life of the resin presser foot is short. When u

Computer pattern sewing machine has a wide range of uses, such as seat belts, bandages, tarpaulins, shoe uppers, leather splicing, sofa seats, etc. all need zigzag pattern sewing to set the trajectory. The pattern sewing machine can be single-needle or Double needle sewing depends on your needs.Upper punching is mainly divided into two types: decorative punching and functional punching. Decorative punching is widely used in the modification of leather uppers, while functional punching mainly refers to air holes, shoe eyelets, etc.
Utilizing a computerized pattern sewing machine to punch holes in shoe uppers is to select punches with different hole diameters and different hole types according to the upper pattern design, and modify the punches to make them suitable for installation on the needle position of the computer sewing machine, and then install the modified punches. Fix the position of the sewing machine needle, adjust the stroke, use the computer program to set the required punching track, and at the same time make the positioning template of the upper sheet that needs to be punched, place the upper sheet that needs to be punched on the positioning template and fix it, and start the machine The punching is thus completed. We have sewing machine for shoes on sale, if you need, you can contact us.
      For example, taking the punching of the front cover of the shoe as an example, the implementation process of punching with a computer sewing machi

The electric control system is the key part of every canvas sewing machine. It is generally composed of a control subject, a control object, and a sensing part, and specifically includes a control box (controller, driver), a motor and an electromagnet, a sensor, and some auxiliary components. The cooperation and linkage of some mechanical parts of the thick-thread sewing machine have contributed to the automation of the sewing machine. Just like the "core" of a powerful computer, the "core" is like the heart of a person. It can make all parts work together and enhance the automation of machinery. The control part of the electronic control system mainly controls the driving operation of two components such as the motor and the electromagnet.
      Thread jumping is a phenomenon that the industrial canvas sewing machine cannot continuously form stitches because the hook at the bottom of the machine cannot hook the upper thread or the upper thread slips off after being hooked during the sewing process of the industrial canvas sewing machine. This is mainly caused by the inconsistency of the movement time or movement position of the needle and the hook. Of course, it is also possible that the needle cannot form a loop and cause the stitches to skip. If there is a jumper, you can find the reason from the following aspects:
     When we encounter skipped stitches on canvas sewing machines, we usually check the following points to determine the

Double needle sewing machine, double needle machine, double needle machine refers to a sewing machine with two needles, and the effect is that the double threads are juxtaposed and parallel to each other. A pair of trousers uses double needles less than flat lathes, so in the workshop, the matching of flat lathes and double needles is about 5:1, but it is indispensable. The efficiency of the double needle is high, and the double thread is parallel and neat. All kinds of double-needle machines have a very troublesome problem, that is, the machine is unstable. The maintenance rate is high, especially after a few years of use, and many phase times are a bit messed up. Many machine repairers can't adjust it well.
        First, we start with the needle post and feed dogs. First adjust the amount of cloth feeding (adjustment dial) to zero. When there is no cloth feeding, turn the flywheel so that the needle column is at the bottom dead point. Loosen the fastening screw of the horizontal feed rocker arm, and adjust the inner distance between the needle column and the presser foot rod to about 1.5mm. If it is not adjusted properly, it will cause skipping and broken needles. Note that the needle drop point of the feed tooth hole will change after adjustment, and the feed tooth should be adjusted to match. The cloth feeding time should be adjusted so that the engraving point of the horizontal cloth feeding cam coincides with the engraving point of the lower

The shoemaking industry has a wide demand, which has also led to the shortage of shoemaking sewing machines, and the number of shoemaking manufacturers has sprung up like mushrooms. Therefore, the number of manufacturers purchasing shoe-making models has increased accordingly. There are many kinds of common auto sewing machine shoes, such as double thread side sewing machine. It can be said that there are many brands in the market, and the quality is also uneven. Therefore, when using this kind of equipment, people will find that there are often broken threads, broken needles, etc. What is the situation?
        We know that people will rest when they are tired, and the machine is the same. Reasonable use can effectively prolong the service life. Problems such as thread breakage, skipped stitches, loose stitches, and broken stitches basically occur when the thread is not properly debugged in the early stage of use.
        For example, the thread breakage problem is basically caused by the threading clip adjustment of the double-thread side sewing machine equipment being too tight and incorrect threading.
        Needle breakage, and the broken needle problem is because the pulling speed of the product is too fast, which leads to the pulling of the machine needle and the breakage of the machine needle.
The flower needle phenomenon is that when the Shoes Sewing Machine sews the upper of the cloth fabri
