Aiming at skipping fault of multi-needle chain sewing machine in sewing the elastic band, this paper analyzes the reasons for skipping phenomenon in detail and gives the corresponding adjustment method. The causes include that curved needle is too close to or too far from the threading needle, the gap between the rod and the needle is improper, the clearance of needle plate is too large, too much thread from needle and so on.Besides, it describes the operation precautions in sewing with multi-needle chain sewing machine, such as method for extracting seam material, techniques for removing chain stitch, tips for non-skilled workers, etc. Through the reasonable analysis of the common skipping fault, it is easy to find the right solution, solve the failure in time and improve the sewing efficiency.
