1. Thread bunching under the fabric
This is one of the most common problems when you are in a project. You may notice a perfect horizontal stitch at the top and a bunched stitch at the bottom. Unlike the common belief that the bobbin is a problem, the thread will roar under the fabric because there is no tension on the upper thread. First, remove the presser foot and rethread the thread. This refreshes the tension system so that it can receive threads perfectly. Next, raise the take-up rod and needle to the highest possible point. Confirm that you have the correct tension.
2. Uneven and skipped stitches
This is another very common challenge. Experienced sewers will know that this challenge is caused by broken, bent or damaged needles. You should change the needle every 16 hours after stitching. Another reason for the challenge of industrial sewing machines comes down to how to handle the fabric when sewing. Many people pull the fabric from behind while sewing. This can easily cause skipped stitches, and in some cases can damage the stitches. When you pull the fabric from behind, what you basically do is force the feed dog. The solution is to change the needle regularly, fix the cloth in place when stitching, and then let the dog move by itself. Do not use the machine forcibly. Work with its pace.
3. Frequent needle breaks
Frequent broken needles can be very annoying. Frequent broken needles are not a big problem. In most cases, they are caused by ignoring the needle usage guidelines. You need to use the correct needle on the correct fabric. The needle size varies from 8 to 18. The smaller size is suitable for light and thin fabrics, while the larger size is suitable for tough fabrics. If you use a 10 gauge needle on denim material, it will definitely break.
