What is the reason for the jumper of the embedding machine?

The three packages of jumper wires for the buried clamp machine generally have the following situations
1. Hooks are curved needle seams without hooks,
Solution: Adjust the relative position between the machine needle and the bending needle at a lower position, so that the needle can be inserted under the bendable needle thread ring;
2. The hook of the curved needle coil smaller than the lower curved needle is hung on any curved needle coil of the upper curved needle
Solution: Adjust the position of the bending needle, so that the loop maker can hang on the bending needle thread loop;
3. Insert the looped needle thread without a sponsor in the needle, adjust the relative position between the needle and the looped needle.
There are many jumpers to investigate, and you need to check for bent needles, any direction, and any loose components.
When the burying machine has too thick material, the jumper can be replaced with a larger needle. It's best to install a tugboat. If there is not much looseness in various parts, they can be adjusted well
