Leather sewing machine is a kind of sewing machine that can sew thick materials with strong penetrating power and thick eating ability, and usually has a large sewing table that allows thick materials to pass smoothly. 
Leather sewing machines are also thick material sewing machines that can sew hard and thick materials such as bags, shoes, and saddles. The leather sewing machine is a professional machine developed for sewing leather products, and its structure and needle are very suitable for sewing this kind of material with certain thickness and toughness. Leather sewing machines can be subdivided into Flat bed sewing machines, Long arm flat bed machines, Cylinder bed sewing machines, Post bed sewing machines, Ornamental sewing machines, Pattern machines and Zigzag sewing machines. Leather sewing machines are essential for sewing leather materials, such as leather clothes, leather sofa covers, leather bags, etc. They can also be used for sewing thick materials.
Structure description of leather sewing machines
Structure Description Leather sewing machine is a good helper for sewing leather products, because leather is thick, tough and flexible, and ordinary sewing machine can't finish the sewing work. Leather sewing machine usually adopts compound feeding or top and bottom feed usually suitable for sewing double layer material supplies.
When we select the leather sewing machine must be well analyzed and researched before purchase, specifically for different purposes, different manufacturers, and different models, there will be differences. For example, when choosing a leather sewing machine, you will face the problem of the length and diameter of the cylinder arm, which is generally divided into small and large cylinder arms. For example, our GC1341-SC-BH machine is a classic small-arm cylinder sewing machine with a diameter of 50mm. Our GC1341 Series machines are classic large-arm cylinder sewing machine with a cylinder diameter of 70mm.
Depending on the thickness and hardness of the material to be processed, the requirements for the thickness of the machine (the thickness that can be sewn well) and the power, including the feeding capacity, stability, and the needle and thread fit are different, thus distinguishing between medium to heavy weight and extra heavy duty material sewing machines. For example, the thickness of the single layer of leather is usually below 2.5 mm for leather goods such as wallets, handbags, luggage, shoes, belts, harnesses, etc. As far as industrial sewing machine design is concerned, these products should be classified as (common) medium to heavy weight sewing machines. Only heels, belts, harnesses and even complex leather furniture are covered by extra heavy duty material sewing machines.
The difference between a medium to heavy weight sewing machine and an extra heavy duty material sewing machine: An extra heavy duty sewing machine is designed for thick materials. The needle and thread and the entire machine are designed for very thick materials, such as, a large shuttle hook or very thick thread and a larger needle and thread size, needle plate, presser foot and feed dog. For the medium to heavy weight sewing machine, it is a double shuttle hook, medium thickness thread, medium size needle and relatively regular needle plate, presser foot, feed dog, etc.
Routine maintenance of leather sewing machines
Some leather sewing machines, also known as thick material sewing machines, can be made into a double-needle structure, with uniform and beautiful stitching and fast sewing speed. They are particularly suitable for mass production in factories. However, in mass production, we also need to consider how to keep the stitching smooth, beautiful, and efficient.
It is extremely crucial for thick material sewing machines like leather sewing machines to run smoothly so that the stitches can be standardized and beautiful. At the same time, it is important to ensure the stable performance of the sewing machine. We need to regularly check the core components of the machine, such as the shuttle, cloth feed teeth, presser foot, needle, motor, etc., to ensure that the machine works properly under long-term operation and to reduce the occurrence of minor problems. It is also necessary to pay attention to the cleaning of the machine. After each work, pay attention to clean up the excess threads, residual materials and dust in the shuttle and fabric feed teeth, as well as the surface of the sewing machine and the internal parts of the panel, to avoid affecting the normal use and operation next time. At the same time, inject lubricant into the machine regularly to minimize the friction and breakage of the parts during operation.
The above maintenance methods are also applicable to other sewing equipment. Only by doing the usual cleaning and maintenance can we ensure the smooth operation of the equipment.
Selection matters of leather sewing machines
When buying a leather sewing machine, we first need to be clear about the purpose and use of the machine so that we can select it with a target. This is because the specific functions of different types and models of sewing machines are not the same. In order to buy high quality leather sewing machine equipment, it is important to pick a product with a certain reputation that can guarantee the quality of the product.
When buying equipment, you should also pay attention to the appearance of the product. Generally, sewing machines from well-known brands look more beautiful and generous. Also, pay attention to the material and seams of the sewing machine, as well as the function button settings and layout of the machine to ensure that the sewing machine is easy to use. The more powerful the sewing machine is, the easier it will be to use, so before you buy, find out what features come with the model you are buying, such as whether it comes with practical features like automatic thread cutting, pneumatic presser foot lift and reverse backstitching.
If conditions allow, you can try out the machine when selecting a sewing machine. When testing the machine, it is important to note that the machine is usually allowed to run at no load for a short period of time to observe the sound and the condition of the parts when the machine is running. It is best to perform a sample sewing, carry a small sample of the product to be sewn, test the use of the machine on the spot and observe the condition of the machine when it is working. This way, even if the buyer doesn't know the machine, he can determine his ideal machine very visually and clearly. The above are a few important things to focus on when selecting sewing equipment offline, and I hope they will help you buyers to purchase the sewing equipment that you are satisfied with.
