meg Posted December 22, 2009 Report Share Posted December 22, 2009 hello - im having some minor difficulties and wonder can you give me some things to try. i am quilting, just small concentrated freehand loop d loops and every once in a while i get a big thread blob on the back and the top thread breaks. this happens maybe once every 20-24 inches. both threads are 35 poly and when they aren't breaking, the tension looks good. i have already rethreaded the top and redone the bobbin. any suggestions????

Quilter 4 Jesus Posted December 22, 2009 Report Share Posted December 22, 2009 Sorry you are having trouble Meg. I can't help much other than suggesting you try a different spool of thread since you have rethreaded top and bobbin. I recently had that issue, Superior Threads is replacing a bad spool of Highlights. I was not getting blobs on the back but the top thread was breaking and the tension would be fine then get distorted before breaking the top thread. Good Luck!!

sewlinzi Posted December 22, 2009 Report Share Posted December 22, 2009 Is the quilt sandwich too tight? Have you defluffed the bobbin case and tension disks? I would probably use a finer thread in the bobbin... Isacord 40, So Fine 50 or Bottom Line 60 Link to comment Share on other sites More sharing options...
Stagecl Posted December 22, 2009 Report Share Posted December 22, 2009 Hmm... I always thought that if there were loops on the bottom from the top thread it meant the top tension was too loose and/or the bobbin was too tight? Make sure your top thread is threaded right and there are no dust bunnies hiding any where. Link to comment Share on other sites More sharing options...
DawnCavanaugh Posted December 22, 2009 Report Share Posted December 22, 2009 Meg, Thread blobs can happen when the thread is slipping out of the tension disks on top (be sure the 3-hole guide is aimed between "8:00 and 2:00"), or is otherwise somehow losing its tension momentarily. Be sure to put a small piece of batting into the first thread guide above the spool to help control the thread as it exits the spool. The same can hold true in the bobbin case. As Linzi suggests, check that no thread lint has built up under the bobbin tension finger on the outside of the bobbin case, that the bobbin is spinning clockwise when you pull the thread tail, and that the "bobbin brake spring" inside the bobbin case still puts pressure on the bobbin to prevent backlash. (You can check that by holding the bobbin case so that the bobbin faces the ceiling. Then tap the bobbin to see if it still has a little "bounce" to it--if it it does, those little fingers inside the case are still doing their job.) Finally, try a different thread off to the side, just to eliminate that as the troublemaker:). Link to comment Share on other sites More sharing options...
