Bobbin Thread Loose And Bunching

Recommended Posts

i have a Pfaff 335 clone machine which has started to bunch/loop the bottom thread.

The machine has been moved and in storage for 3 months until I put it back in action.

All solutions I have read say its usually from incorrect threading or wrong top thread tension.

I have checked all this, tried different tensions, cleaned the tension discs.

Sometimes I get a clunk noise after a few inches sewing.

Also it doesn't seem to pick up the bobbin thread very well when loading a new bobbin.

Has the timing gone out or something?

I think its probably your top thread that's bunching on the bottom. I can't really tell from the pictures but if there's any doubt load the bobbin with a different colored thread so you can see what's going on. It can be from not enough tension on top.

Before you do anything please five the bottom end a thorough clean!

Don't think any combination of feet would cause this problem! There is a major issue with the top threading!
