Members Pinsplitter Posted February 27, 2013 Members Report Posted February 27, 2013 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? pics of problem below. Quote
Members billymac814 Posted February 28, 2013 Members Report Posted February 28, 2013 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. Quote

Members Anne Bonnys Locker Posted March 3, 2013 Members Report Posted March 3, 2013 Don't think any combination of feet would cause this problem! There is a major issue with the top threading! Quote
