Pfaff 7570 bobbin tension

I have owned this machine for several years and this is the first time I have had a problem with the bobbin tension. It seems to be tight enough when I **** it in fact it seems almost to tight but when I sew a straight test strip the top stitches are looped underneath and you can pull the bottom thread straight out. If you do more than 3 inches it will start to gather and then break the bobbin thread. Is this adjustable or am I going to have to get a new bobbin? I haven't sewn in a few months but I would not think that would be the problem. I have also cleaned and oiled it. Thanks for your help. Sandy

What to do if sewing machine is puckering?


Depends on why the seam is puckering. Read this: http://www.amefird.com/wp-content/uploads/2010/01/Minimizing-Seam-Puckering-2-5-10.pdf
Offhand, it sounds like you need to reset the top tension properly.

The top two photos here are the upper and underside of a single ply of muslin sewn with a balanced tension. The blue thread is on top, red in the bobbin: http://www.picturetrail.com/sfx/album/view/22521551 -- that will give you something to shoot for.

I need to access the tension plates on my Pfaff creative 7570


To access the tension disks, remove the top of the machine as follows: 1. With the carrying handle raised, remove the cover (the piece that has all the stitches pictured). 2. Unscrew 2 screws completely; one is in the depression where the thread spool goes and the other is right behind the bobbin winder. 3. pull straight up. You may have to jiggle it a bit. 4. you should be able to see the tension disks from here.

Unlikely you will have problems with the tension springs, make sure you have the thread coming from the bobbin with only the slightest tension, failing that your machine may be slightly out of time

Bobbin tension too loose


You don't give us the make and model of your machine.... so it's hard to give you decent specific advice. Secondly your question isn't making sense. If you are getting loops on the bottom your top tension isn't right(too loose) if your loops are on top your top tension isn't right.(too tight) The only time you would mess with bobbin tension is when you change thread weights significantly. Like from 40 weight to 92 weight or visa versa.



Look at your bobbin case, bobbin carrier, shuttle/carrier..... there is a spring (it's a flat piece of metal) on the spring is a small screw. Use a small screw driver and tighten the spring 1/4 turn. Loosen your top tension a couple turns. (remember right to tight, left to loose)

I have a Kenmore sewing machine - 12 stitch model which I bought in the 70's. I am having a tension problem and can't seem to fix it. What is the normal setting for the top, and bottom?


Hello

Load your Kenmore sewing machine with the right thread and bobbin thread for your project. If you use the wrong weight thread for your fabric or severely uneven weights of thread, this can cause the appearance of a tension problem when it is, in fact, a thread weight problem or a problem with your sewing speed. If you go too fast, you will break the thread. If you go too slow, you can cause loops. Uneven pressure can cause stitches to vary greatly.

Test your Kenmore sewing machine's tension by sewing on a piece of scrap fabric. If your tension is way off, then test on some basic cotton or a firm blend simply to get your tension right. Do not try to start adjusting your tension on silk or leather. Get a base adjustment on a more standard fabric first.

Look at the top threads and bottoms threads. If the tension is off on one side, it will usually affect the other side slightly. So select the side that looks more maladjusted to start adjusting the tension.

If the top thread is too loose or too tight, you will need to adjust the tension dial. This dial is usually located a few inches above the needle on the Kenmore machine body. Usually, your machine will have markings to indicate which direction tightens the tension. If these have worn off over the years, watch the dial as you turn it. If it appears to move toward the machine body, then it is tightening.

If the bottom thread is too loose or too tight, then you will need to open the door to the bobbin case. On some Kenmore models, there is a little screw near the bobbin case that can be adjusted slightly to adjust the tension. On other Kenmore models, there is a screw on the bobbin case itself--not on the bobbin, but on the bobbin's casing. This will also adjust the bottom thread tension. Adjust the bobbin thread tension to make slight changes.

If the thread is looping severely on one side, the thread weights might be off. For instance, look to see if you have a lightweight thread on the bobbin and a heavyweight one on the top. If the thread keeps breaking, the top tension or bottom tension could be too tight or the thread is too lightweight for the material you have selected. Check your combination of threads and material. Also make sure you are using the right weight needle and the right foot for the sewing step or project you are working on.

If your Kenmore sewing machine's tension is off severely or if you have not used your Kenmore in a long time, then you might need to take your machine in to be serviced. Sometimes, the inner parts need to be oiled or the entire machine might need to be cleaned and calibrated by a professional. If you sew a great deal or if your machine sits idle a lot, both situations will usually require some servicing to keep your Kenmore sewing machine and its tension in perfect working condition.

Check the bobbin tension and that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.
