Frequently Asked Questions
Q: What is the primary advantage of the triple compound feeding system?
The triple compound feed (top presser foot, bottom feed dog, and needle feeding) ensures that the upper and lower layers of thick materials do not shift, resulting in neat, beautiful, and precise seams even on viscous materials.
Q: How does the 5x big rotary hook improve productivity?
The oversized hook significantly increases thread capacity, which reduces the frequency of bobbin changes and allows for the use of very thick upholstery threads, thereby increasing overall working efficiency.
Q: Which model should I choose for larger items like outdoor tents or boat sails?
Depending on your size requirements, we offer arm lengths of 15" (381mm), 20" (508mm), and 30" (762mm). For very large products, the 30" arm version (JW-8BL30 or JW-28BL30) is recommended.
Q: Is the machine suitable for automotive car seat cover production?
Yes, it is specifically designed for leather and cloth car seat covers, as well as luxury leather sofas, where high requirements for beautiful and durable stitching are essential.
Q: How does the clutch device protect the machine?
The clutch device acts as a safety mechanism that prevents the rotary hook from being damaged during overload conditions, protecting both the equipment and the workpiece from mechanical failure.
Q: What are the power requirements for the motor?
The machine is available with two motor options to suit different regional power standards: a 550W 380V motor or a 750W 220V motor.
