Question about PfaFF Creative 7570

1 Answer

Thread bunching underneath fabric as I sew.

I have tried to adjust the bobbin tension to no avail. The machine was sewing just fine then started to bunch underneath. The lower tension is obviously the problem. I re-threaded, cleaned and changed the needle. I hadn't used the machine often when this started to occur. The last thing I sewed on it was polar fleece but I was always careful to clean the machine after use. I haven't been able to use this Pfaff for years. I really need my machine back. I am hours from the nearest Pfaff dealer and as a single Mum I am too broke to pay for the service/repairs. If anyone has any suggestions, for home repair, I would appreciate them.

You may need to take off the housing that covers the whole dog mechanism. You will need a screwdriver to do this. Blow out the area around the tension gears and dogs, check for loose or disconnedted parts, and re-oil the gears. Fleece fuzz usually collects where you can't see it. This was the problem with my machine that had the same symptom.

Top thread is bunching underneath


bunching underneath is an indication that the top tension is incorrect
switching projects and materials also that attention has to be given to tension adjustment both bottom and top
the catching sometimes indicates that a tension is too tight and is pulling the needle out of line

It just started sewing upside down it was fine earlier, I have just rewound the bobbin


1. You will likely need to adjust the bobbin tension. Make sure that you have placed the thread under the tension spring to start with.
2. If it is bunching up on the bottom your tension on the bottom is too strong. Before you do anything you can increase the top tension to offset this so you won't need to mess with the bobbin if it isn't a great amount.
3. JUST FOR INFORMATION: When you change threads they are either thicker, thinner or the same. This will require most of the times to adjust the bobbin.

Hello. Make sure the bobbin is not backward. It seems the upper tension is still not adjusted right. If the bobbin pulls smooth focus on the top tension. Good Luck

If You have a drop in bobbin you will have to remove the hook and adjust the tension, however try adjusting the top tension before you remove the hook.

Problems with lower thread tension


Did you bend the throat plate? I have done that and it was a nightmare. I took it off and gently hit it from the backside with a towel over it to bend it back the way it was. It worked fine.

Thread bunching on model singer 2157C


According to everything I've researched, when this happens it's because there is no tension. Check & make sure it's threaded properly. If it's still bunching underneath, then there may be something wrong inside the machine - even though you adjust the tension, it may not really be happening inside. You'll have to take it apart or service it.

Try a different bobbin. Look for one that is a little narrower. I had the same problem and changing to a narrower bobbin fixed it.
