For Everyone To Explain The Sewing Machine Sewing Principle
Like the car, the basic principles of most sewing machines are the same. The core of the car is the engine of the internal combustion engine, the heart of the sewing machine is the coil suture system.
The stitching method is very different from ordinary hand stitching. In the simplest manual stitching, the sewing machine puts a thread in the small eye of the end of the needle, and then passes the needle together through two pieces of fabric, from one side to the other, and then back to the original side. In this way, the needle moves into the fabric and stitch them together.
Although this is very simple for the manual, but it is extremely difficult to use the machine to pull. The machine needs to release the needle on one side of the fabric and then grab it again on the other side immediately. Then it needs to pull all the loose lines out of the fabric, turn the needle in the direction, and then repeat all steps in the opposite direction. This process is too complicated for a simple machine, and not practical, and even for the manual, it is only with a shorter line when easy to use.
