There are three main types of sewing machines for making shoes: single-needle sewing machines, double-needle sewing machines and three-needle sewing machines.
Single-needle sewing machine is one of the commonly used sewing machine models for making leather shoes, sports shoes, etc. It is suitable for sewing various leather, textiles, plastics and rubber materials. Single-needle sewing machines can sew materials on a flat surface and along a curve. The stitches are clean and firm, which can meet the requirements of production. However, due to the high operating frequency of the single needle and the different thicknesses of materials such as the upper and sole during work, it is easy to cause the thread to skip stitches, affecting sewing efficiency.
As the name suggests, the double-needle sewing machine has two needles that can sew two stitches at the same time. It is suitable for processing materials of different thicknesses, such as sewing the upper, sewing between the sole and the upper, etc. Since the double needle can better fix the material, the stitches are more firm, and the sewing speed is faster than that of the single-needle sewing machine. However, the disadvantage of the double-needle sewing machine is that since sewing two stitches at the same time requires a wider space, the width, structure and weight of the machine body are required to be higher.
The three-needle sewing machine is a sewing machine with the largest number of needles. It is generally suitable for sewing footwear such as sports shoes. The three-needle sewing machine has a more stable stitch than the double-needle sewing machine and can adapt to higher-intensity sewing needs. At the same time, it can also sew multiple layers of materials, shortening the production cycle. However, the sewing capacity and speed of the three-needle sewing machine are lower than those of the double-needle and single-needle sewing machines, and the price is relatively higher, so it is necessary to choose according to production needs when using it.
In summary, there are three main types of sewing machines for making shoes: single-needle sewing machines, double-needle sewing machines and three-needle sewing machines. Different sewing machines have their own advantages and disadvantages and are suitable for different production demand scenarios. For footwear manufacturers, choosing a suitable sewing machine can improve production efficiency, reduce production costs, and thus obtain better economic benefits.
