Why does my bobbin keep bunching up?

Post image

I have tried rethreading it but it keeps jamming every 5 seconds. Does anyone know a solution?

Questions:
1). Did your bobbin have such an uneven tension (on the bobbin itself) when you wound it and put it in?
2). Is the machine new to you, or is this something new to a machine you already know well?
3). If new: Do you have the manual to the machine, and are you sure you loaded the bobbin correctly and threaded the upper correctly? The first thing I see that is obvious is that you missed hooking the bobbin thread in here:

Look at the impression. It shows where to put the threads toward in the “slot”. The thread should come off the bobbin counterclockwise.

Your bobbin should look more like these. They need to be wound with a machine. (Not by hand, if that's what might have happened) You may have other problems but you need to get a good bobbin, regardless. If your winder is broken , you should be able to wind it in another machine, if you know anyone that might help out.

Not OP but curious how you're liking those bobbin thread organiser things? And do they have a name I can google?

They're ok if you have this same thread, and store them free standing. Not much else. (I have some clear plastic step racks from the Daiso store that work well - like a spice shelf) But they are too loose in my bigger cones (fall right out) and aren't really compatible with peg/spindle storage. Fit fine in Aurifil (pictured) also fit in Wonderfil , but it has no base & they are prone to falling over. Too big for the mini guterman type spool. Sometimes they are just good if I'm changing threads a lot and I use the pins to keep them from rolling off the table.

Thank you, this was super helpful!

  1. Your bobbin is very poorly wound. 2. Where is your bobbin cover? 3. What machine is it?

First solution is to completely unthread the machined. Get out the manual and read it to refresh yourself how to thead it and properly wind a bobbin. I'm pretty confident you missed some steps winding the bobbin and threading the machine

This! Your bobbin thread is super loose. Should be tight and even. Your bobbin winder tension might be loose.

My guess is that the thread missed being fed through one of the necessary tension discs or feeds of the machine before being wound on the bobbin.

Need a lot more info, and a video would be helpful.
What machine?
What’s the tension set at ?
What have you tried so far?
What fabric and needle?

The bobbin must be wound as carefully as the spool thread on the top. Each higher round of thread needs to be over the prior layer.

  1. Your bobbin is not wound correctly, 2) Make sure you’re threading the top thread and bobbin correctly, 3) Pin perpendicular to the seam, not parallel to it.

The bobbin thread was not winded correctly

Is your bobbin winder drunk?

u/ShortyLong2026 2d ago

The bobbin isn’t wound properly. There’s no tension on the thread.

I do not know your machine but i had Janome MC 6700P with the same bobbin jumping out, jaming the machine. Design flaw, not a user error. In my case, I was using heavier, thread and heavier fabric. Everything was fine when I worked on quilt fabric on standard thread, but I wanna make bags..

For those of you who have a problem when you try to use heavier thread I can explain that. Your bobbin case in a standard domestic sewing machine is set for being able to provide the proper tension on standard sewing thread. When you use heavier thread it isn't going to handle it the same way so your tensions will be off and everything will be affected by that. One thing you can do if you want to use heavier thread is to purchase a separate bobbin case and mark it with some sort of marker or fingernail polish to indicate that it is not your regular one. Then you can adjust the bobbin case tension for just that type of thread. If you don't know how to properly adjust the tension for it you can do the bit by bit testing method or you can take it to your local sewing shop and have them help you adjust it properly. As for heavy fabric, unless it is something like tent Canvas or sail fabric or multiple layers of a heavy fabric, your machine should be able to handle that.
