Industrial sewing machine section thread

If the industrial sewing machine finds that there is a broken thread during use, we must first check every part where the sewing thread passes to see if there is any burr or something that causes the upper thread to be cut. Then it is necessary to check whether the needle of the sewing machine is bent. Next, we need to check the needle plate and the positioning hook of the hook to see if they have burrs or concave surfaces. If any burrs are found after the inspection, the burrs should be removed in time, and then smoothed with sandpaper.

If the part is worn and has a concave surface, it is necessary to consider changing a spare part so as not to affect the normal operation. Generally speaking, the threads used in sewing machines are very thin and easy to break, so we must ensure that every place where the upper thread bypasses is smooth to avoid thread breakage.
