SGB4-1/4-3 type upper and lower composite feeding flat sewing machine (canvas sewing machine)

Product features:

Using a single needle shuttle to form a double line lock stitch, a lifting feeding tooth, and an alternating presser foot, this mechanism can ensure that the upper and lower layers do not move when sewing slippery, sticky, and extra long products at any length of needle spacing within the rated range, making the products neat and the stitches beautiful. The connecting rod wire picking mechanism increases the spindle speed, reduces noise, ensures the overall quality of the machine, and extends its service life.
Usage: Thick material products such as hemp wheels, polishing wheels, truck tarpaulins, canvas, tents, container bags, ton bags, space bags, safety harnesses, industrial harnesses, synthetic fiber lifting belts, harnesses, quilts, saddles, etc.
