Regarding the operation of the woven bag bottom sewing machine, please refer to the operating instructions to avoid various problems caused by unauthorized operation, such as skipped stitches and overheating. Here, Xindeli will explain the repair methods for skipped stitches on the woven bag bottom sewing machine:

1. The thread is not threaded correctly; re-thread according to the "Threading Diagram".

2. The straight needle is not installed correctly; check the height and facing position of the needle so that it is slightly in front of the needle plate hole when the needle moves downward.

3. The tip of the straight needle is broken or bent; replace the needle.

4. The tip of the curved needle becomes dull; use sandpaper to sharpen the needle, or replace the curved needle.

5. The suture tension is too high or too low; adjust the suture tension to the appropriate level.

6. The curved needle cannot cover the loop of the straight needle on the left side, causing the right stitch of the lower decorative thread to skip stitches; if the loop is too small, increase the amount of thread taken up appropriately.

7. The looper should not simultaneously cover the loops of the middle and left straight needles, causing skipped stitches on the middle and left stitches of the lower decorative thread; if the loop is too large, reduce the amount of thread taken up appropriately.
