Is the thread old?

You may try removing the bobbin holder to make sure nothing foreign is embedded or around it. Once, after sewing over pins, which I KNOW I shouldn't do, my bobbin acted up and I found two badly bent and broken pieces of pins under the bobbin holder. They were bent enough to stick up and cause problems. Also, that would be a good chance to take a brush and clean out lint from that area, something I need to do more often! Debbie

Yep I have had that happen, just recently. It had nothing to do with a sharp object because mine loads at the top of the machine. I think the thread gets loose and it just goes out of control. It happened to me with a very fine thread. I removed that bobbin and did another one and it was fine. So, I will segregate that bobbin as maybe a bad bobbin. (probably toss it as I have lots) Anyway, it happens and as long as it doesn't do it every time or on a frequent basis, I refuse to worry about it! LOL

WOW - that's one for the books. I've had thread get gunked up, but not cut like that. I don't know what to say or recommend, sorry.

I HAD THAT HAPPEN ONCE ALSO. I TOO THINK THE BOBBIN WAS WOUND TOO LOOSE.

Have had that happen a few times in my life. Never remember from one time to another what caused it but it's happened....... again! All I've ever been able to do it just cut it loose from the machine and start over again.

Is it a pre-wound bobbin or did you wind it yourself. I am curious? I don't buy pre-wound bobbins.

I wound it myself. I think I wound it on the wrong speed!

I've had it do a similar thing--I had to cut the bobbin out because just tangled in there--the bobbin had not wound correctly.
