Double-needle sewing machine can also be called double-needle flat car. Double-needle is a very important equipment in clothing machinery. Double-automatic sewing machine is mainly used to process all kinds of clothing. It is an indispensable machine for clothing and other industries. It can greatly enhance work efficiency, and the double lines are parallel and neat.
Double-needle sewing machine is a commonly used sewing machine with two needles and two synchronizations, and the effect of turning corners is that the double threads are juxtaposed and parallel to each other. If the two needles and the presser foot work together synchronously, we can also call it three-synchronous, and three-synchronous sewing machines are very common in the current sewing machine market.
Sometimes the flat car can replace the double needle, but it is only suitable for a small amount of production, because it is slow and the thread is not smooth, which affects the appearance, so the double needle sewing machine is essential in many cases. The double-needle type is used in sewing machines of flat car and computer car.
