Abstract: Sewing machine principle, process and technology: the types of sewing machines. Uses. The following is an overview of the knowledge about sewing machines. The following content is organized by Buy.com. For your reference.

The main difference between machine embroidery and hand embroidery is that the former is done by sewing machine and the latter is done by hand, so sewing machine is a necessary tool for machine embroidery.

industrial sewing machine

Sewing machines have been invented for over 100 years. At the beginning of this century, American Singer sewing machines were first imported from Shanghai and Guangzhou. Since then, Germany, England, Japan and other countries have also set up marketing agencies in China and imported various sewing machine parts. Since sewing machines were practical production tools, their production efficiency far exceeded that of handwork and they were easy to use. Therefore, they were soon accepted by craftsmen, production factories and households, and the number of different types of sewing machines gradually increased. For example, the 15-80, 44-13, 96, etc. from Katsuya. With the increasing social ownership of sewing machines, an early sewing machine repair industry was soon formed. After the thirties, the country began to develop from distribution and repair to manufacturing. The company had monopolized the market for a long time and had a deep influence on the sewing industry and the sewing machine manufacturing industry, such as garments, shoes and hats. Before the liberation, the sewing machine manufacturing industry in China remained at the stage of repair and imitation, with the most imitations of Shengjia brand sewing machines. Most of the model names also followed the foreign names. After the liberation, China’s sewing machine manufacturing industry developed rapidly and the number of domestic sewing machines increased continuously. In 1957, the Ministry of Light Industry held a national professional meeting on bicycles and sewing machines and formulated a unified model of sewing machines in China, which was promulgated and implemented on a trial basis in 1961 (QB159-61 product numbering rules. Ministry-issued model regulations for domestic sewing machines

Over the past twenty years, the variety of sewing machines in China has developed greatly, and many of them have been eliminated and new ones have emerged. For this reason, the Shanghai Sewing Machine Research Institute was responsible for drafting the new standard “Rules for the Preparation of Sewing Machine Products” in 1983, which was approved by the State Bureau of Standards and numbered CD4514-84. Today’s sewing machines are developing in the direction of high quality, high performance, multi-species, multi-specification and multi-purpose. Domestic sewing machines are developing towards electronic computerization, and some industrial sewing machines have realized computer control, so it is difficult to correspond to the past types of sewing machines produced at present, in terms of structure and performance. Now we can only compare some of the similar domestic and foreign sewing machine models. For your reference when classifying them.

I. Household sewing machines are generally used for the production of machine embroidery.
According to incomplete statistics, there are dozens of varieties of domestic production of household machines, which can be roughly divided into four categories: type JA, type JB, type JG and type JH. All these four types of machines can be used to make machine embroidery. Based on the long experience of machine embroidery, it is generally believed that the JA type sewing machine is the most convenient to operate. Among them, the JA1-1 household sewing machine (Figure 4-3-1) is one of the main varieties of household sewing machines produced in China. Although the names of the brands produced by each factory are different, all its parts are manufactured and accepted according to the uniform standards of the Ministry. This model has a long history of production, stable product quality, precise and durable structure, high interchangeability and low price, and it is generally the most used sewing machine for making machine embroidery products.
Due to the great changes in the market supply and demand in recent years, the state adjusted the production factories and output in 1983 and 1984, and reduced the number of factories from 44 to 17. In order to meet the needs of the domestic market for brand-name sewing machines, Shanghai and Shaanxi adopted the form of inter-provincial and municipal joint venture to expand the output of brand-name household sewing machines. According to the statistics of relevant information. Shaanxi Sewing Machine Factory and Jingjiang, Yiyang and Suzhou Sewing Machine Factories produce “Standard Brand”, Shanghai Three Factories and Liuzhou and Wujiang Sewing Machine Factories jointly produce “Bee Brand” JA2-12 and JB1-1, Shanghai Xiechang Sewing Machine Factory and Huifeng Sewing Machine Factory and Nanjiang Branch Factory jointly produce “Standard Brand”. Shanghai Xiechang Sewing Machine Factory and Huifeng Sewing Machine Factory and Nanjiang Branch Factory jointly produce “Butterfly Brand” JB8-2, Shanghai Sewing Machine Company and Wuhu and Laohekou Sewing Machine Factory jointly produce “Meishi JA1-Type”, Shanghai Sewing Machine Shop and Nanchang Sewing Machine Factory jointly produce “Shenjia Brand “JA1-1, Shanghai Yangpu Xinshen Sewing Machine Distribution Department and Xiangfan Sewing Machine Factory jointly produce “JA2-1”, Shanghai Fenfa Sewing Machine Parts Factory and Guo County Sewing Machine Factory jointly produce “Jinying”. JA-1, Shanghai Department Store Sewing Machine Department and Hangzhou Sewing Machine Factory jointly produce “Crown Brand” JH1-1, Shanghai Chunlei Industrial Machine Factory and Wuhu Sewing Machine Factory jointly produce “Chunlei Brand” JA1-1, and there are also “Pujiang”, “Angel”, and “Angel” sewing machine factories. In addition, there are also “Pujiang” “Angel” “cloud media and other household sewing machines produced by Shanghai sewing machine production industry and joint venture with foreign provinces and cities.

Second, universal embroidery machine
Besides domestic domestic sewing machines which are the main production equipment tools for machine embroidery process, universal embroidery machines are also the main production equipment tools used in larger scale professional factories for embroidery. At present, what people call the universal carriage generally refers to three kinds, one is the JH3-1 machine among domestic sewing machines. This is a semi-automatic multi-purpose sewing machine, which is used in addition to general sewing and embroidery. With the addition of the swing bar structure (commonly known as the jumping needle structure), it can automatically control the lateral movement of the machine needle by the flower die cam, thus embroidering various regular multi-straight strip patterns, which is very convenient as the trim of the machine embroidered products. The other two are imported, one is Japanese universal car (STA GER, MODE LSZ-21-1), of which 821 has feeder structure, which is special for wrapped stems sewing, and 823 has no feeder structure, which is embroidery universal car. Another kind of universal car is imported from West Germany (PFAFF260-261, Figure 4-3-2).
The PFAFF260-261 is a sewing machine imported from West Germany, also known as a household multi-purpose sewing machine. In addition to general sewing and embroidery, it can also be used for button stitching and button hole locking. With the addition of the cross-stitch structure, the machine can not only stitch and roll hems, but also automatically control the movement of the needle by means of a specific cross-board cam (flower die). Together with the feeding structure it can sew and embroider about 40 kinds of colorful and regular straight patterns, therefore, it is customarily called semi-automatic universal carriage.
