Model Selection for Leather Sewing Machines
2026-02-11
Leather sewing machines are the primary equipment for industrial production of leather goods. Leather products vary in thickness and hardness, requiring different types of leather sewing machines to be selected accordingly.
In industrial production, leather sewing machines are commonly referred to as high-speed machines, cylinder-arm machines, medium-thickness sewing machines, or heavy-duty sewing machines. Cylinder-arm sewing machines vary in cylinder arm length and diameter. Based on cylinder diameter, they are typically categorized as small-mouth high-speed machines and large-mouth high-speed machines. Small-mouth high-speed machines generally have a cylinder diameter of approximately 50mm or less.
Generally, based on the thickness and hardness of the processed material, the machine's thickness capacity, power, feeding capability, stability, and needle-thread coordination requirements differ. This leads to the classification into medium-thickness sewing machines and heavy-duty sewing machines.
Common types of leather goods include: wallets, handbags, luggage, footwear, belts, and horse tack. For items like wallets, handbags, and even structurally complex backpacks, my current understanding is that their single-layer leather thickness generally falls below 2.5mm. From an industrial sewing machine design perspective, these products should be categorized under (standard) medium-thickness sewing machines. Only items like footwear, belts, horse tack, and even some complex leather furniture require heavy-duty sewing machines.
This demonstrates that even within leather goods, the required sewing equipment isn't entirely uniform. Different thicknesses and hardnesses of leather necessitate corresponding equipment tailored to their specific needs.
