What is the difference between a synchronous sewing machine and a flat sewing machine?

[Emilia]

Here is an introduction to the differences between synchronous sewing machines and flat sewing machines: Different working ranges: Industrial sewing machines are not the same as flat sewing machines. The correct term for flat sewing machines is industrial flat sewing machines. Machines used for making leather bags are thick material machines, and of course, they are all synchronous sewing machines. The so-called synchronous means that the needle bar, feed dog, and presser foot all move synchronously. Different structures: A flat sewing machine cannot be modified into a synchronous sewing machine, as there are significant structural differences. For example, a large shuttle flat sewing machine cannot be equipped with synchronous features. In a sewing machine, the material is driven by the feed dog, while the presser foot remains stationary, increasing pressure to enhance friction and ensure the material moves at a constant speed. In a synchronous sewing machine, the presser foot can move like the feed dog and is synchronized with it. This presser foot not only increases pressure but also reduces friction, allowing for much faster speeds. However, synchronous sewing machines are only used for specific tasks.
