Common Questions
1.What is"needle feed"? Compared to the conventional one, what advantages does it have?
The needle feeding and the feeding teeth move synchronously, jointly pushing the fabric. Compared with the single-teeth feeding method, needle feeding can effectively prevent layering or shifting of high-density fabrics or soft fabrics during sewing. It ensures that the upper and lower layers of the garment pieces are always aligned, resulting in higher sewing accuracy and more beautiful and stable stitch patterns.
2.This machine is"computer direct drive".What exactly does this mean?
1.Direct drive motor: It refers to a servo motor that is directly installed on the machine's main shaft, unlike older machines which are connected through belts. This results in a more sensitive machine response, lower noise, less vibration, and greater energy efficiency.
2. Computer Control: The machine is equipped with a computer operation panel and has four automatic functions, which can significantly enhance production efficiency.
3.Which fabrics is this machine mainly suitable for sewing?
With the needle feed structure, the DT 7903-D4 has very strong adaptability to fabrics. It is suitable for sewing medium-thick and thick fabrics.
