Answer:
1. CAUSES: Skipped stitches are usually caused by an old or worn needle. With every stitch, there is friction placed on the point of the needle and with repeated action, the needle experiences abrasion. Over time, the needle becomes dull and doesn't perform well. This results in skipped stitches.
REMEDIES: Check machine clearances and timings. Check if the needle is inserted and aligned correctly. Use a needle with a deeper scarf.
2. CAUSES:
- Needle Not All the Way Inserted. ...
- The Needle Screw is Not Tight Enough.
REMEDIES: Polish rough edges and replace if necessary. Replace the needle being used with a higher quality needle.
