Threading and tension on the Pfaff 1445

SOURCE: Bottom (bobbin thread) makes loops

I don't have the same brand as yours, but on my machine there is a little screw on the bobbin case that you tighten to increase the bobbin tension. If you've got one, turn it 1/8 to 1/4 turn at a time.

SOURCE: thread or bobbin tension

Thread tension. Beware of adjusting the bobbin screw. Pfaffs maintain their tensions just fine without adjusting the bobbin tension, unless you're using some crazy thick or fine thread. If you must change your bobbin tension, you would be well-advised to buy an extra bobbin case, because re-calibrating your tensions after changing them can be less than fun.

Increase your top tension, and your looping should cease. I normally keep my tension around 4.5. Also make sure you're using a good quality thread, and that there's nothing in the upper tension assemblies. Sometimes a tiny piece of debris can keep the top tension from applying enough tension, so turning the machine off and blowing some canned air in there can help as well.

Good luck,

First make sure your needle is in correctly. Then make sure you are threading the machine correctly especially make sure you thread the take-up lever. Make sure your tension dial is at a 4 to 5. if this does not work, let me know

If the thread is looping underneath, you're top tension may be too loose or the thread may not be in the take-up lever. If it's looping on top, double check that the thread is in the bobbin tension or that the bobbin tension isn't too loose.

Make sure your are lowering the pressure foot first before you start sewing. With the free motion foot, you still have to lower the pressure foot, this allows tension to be put on the top thread and allows the foot to work properly (when the needle goes down so should the foot and when the needle comes up it should lift the foot up.)

Also make sure your tensions are in a middle setting and that you are threading the machine with the pressure foot up.

The way to insure you will not get your problem is with the foot up, you should be able to pull the thread easily right before the eye of the needle and when you put the foot down you should then feel a fair bit of tension on the top thread.

hope that helps :)
