bobbin thread?

[Bonnie in Ok]

working on a quilt that has two battings in it. Tension seems to be good and the stitching is looking good but the bobbin thread keeps getting wrapped around the latch on the bobbin case. I have checked to make sure it is not wrapped around it when I put it in but eventually ends up around it and I have to take it out and put it back in. Does anyone have any ideas why this is happening? Do I to adjust something? Wondering if I am getting to much flex on the needle because of the thickness of the batting but it seems to be sewing well.

Don't have a clue so need help.

Have you got the bobbin in the case in the right direction? Maybe you need to flip it over?

This happens to me as well sometimes but I have no idea why. I run a gammill so my bobbin case is large but it's all the same mechanics. I'd be interested to know also why this happens.

Linda--for me, the bobbin is in the right way so it isn't that.

I"m wondering if your hopping foot is too low. I know it sounds odd to consider that but perhaps from the two battings it isn't allowing you to make a complete stitch and the bobbin thread can't pull up like it should. The other thing I'd look at is to see if your backlash spring isn't working right.

This happens on my Milli sometimes too and when I'm only using one layer of batting. I too would like to know why.

I've had this happen as well with only one batting but that normally is when I'm moving the needle too fast, which actually might be the problem here as well. Maybe there is too much flex with the double thickness so try a larger needle.

Try slowing down, sometimes the friction/ density of the material will cause the thread to flip around after it pulls tight and then suddenly releases, this can cause a loop big enough to go guess where, even with the tension set correctly. Heidi is right with the hopping foot too as it will compress the thicker fabric/ batting and cause more friction if not set right. Just a guess and works for me, hope it helps -----Dave B.

This may not help for this quilt, but what threads are you using for the top and bottom? It may be that the bobbin thread is much thinner than the top thread, so is 'losing the tug of war.' You can adjust for that, but matching top and bottom thread thicknesses usually results in less tension problems. Just some thoughts.:cool:
