For common needle skipping faults of the interlock sewing machine, we first need to confirm its causes and then carry out the targeted treatment.
We can preliminarily determine the cause of the interlock sewing machine by the following simple methods:
1. Check whether the needle is intact, such as bending, blunt point, correct installation, etc;
2. Check whether the case line is correct, especially whether the line is on the line baffle. If it is not on it, it is easy to skip the needle;
3. Check the quality of the thread and whether silicone oil should be added for lubrication.
After the preliminary inspection, if the above points are eliminated, we should check the relationship between the machine needle and the bending needle.
