Up-and-down feed dog and alternating presser foot are adopted in this model. Such a structure ensures that the upper and lower layers will not displace under any needle pitch, sticky material or super long products so as to obtain orderly products with beautiful stitches. The link take-up system increases the speed of the main shaft and reduces noise, ensuring the quality of the whole machine and prolonging service life. Oversize oscillating shuttle may be used to increase thread volume and to reduce number of times of thread change-over to enhance working efficiency.
