Machine will not move material under pressure foot. Thread get all bound up like tension my be too tight!

For feeding the material, check that the feed dogs are in the "up" position and not set for darning or free motion quilting.

For the thread jam:
Clean the bobbin area of any lint, threads, or debris.
Be sure to clean the feed dogs and under the needleplate.
Install a brand new needle.
Remove the thread from the machine.
ALWAYS RAISE the presser foot when threading.
Rethread the machine from the beginning.
Verify the thread path is correct.
Set the upper tension to the midway point
Retest the machine.

first thing first - thread inside bobbin should be tightly wound in. Insert bobbin into bobbin case and thread through slot and under the spring. Spring has small screw which regulates the tension. Hold the thread like yo-yo and jerk a little down-up. It should drop just a little (not run down) - that is usually required bottom thread tension,
if not, regulate with the screw. Set top thread tension 3 and sew. If still looping under, increase the top tension higher till the looping disappears. .

Hello, Most often if the machine sews fine on a regular material, cotton, denim, ect.....then the material...in this case "stretchy" is moving up and down with the needle...this is called "flagging" the material moves ever so slightly and this cause the hoop that the hook would pick up to be either not the right size or just a fraction out of line with the travel of the hook. On most industrial machines you can increase the presser foot pressure and cure it. From time to time the size of the hole in the middle of the presser foot can allow movement... so you might try applying a sturdy tape or material to the under side of the foot in order to reduce the hole side.

Hope this helps!!

Hello
It sounds like you are trying to balance the top and bobbin thread so it locks perfectly. If so, this is accomplished by balancing the thread "tension". If you see loops on the underside of the fabric, tighten (increase) the tension. If loops for on the top, lower the tension.

If the fabric is puckering: reduce the stitch length AND you may need to use a finer needle along with finer thread in the bobbin and on top.

Presser foot pressure is rarely adjusted, unless sewing with extremely variable fabrics. For example, pressure is lowered when sewing with silk chiffon as it transports easily under the presser foot (and to prevent damage to the fragile fabric). Whereas pressure is increased when sewing with tent canvass to allow the feed dogs to be able to 'grip' and move the fabric.

Happy Sewing!

loops under the "material" mean the top tension isn't tight enough.

Check the tension of the feed foot. Some machines have an adjustable tension for the foot pressure. If this is not the case then re-check your thread tension setting. As well clean the bobbin area of loose threads and dirt. You can adjust the bobbin thread tension on the side of the bobbin holder(small screw). From the sounds of your dilemna the bobbin tension may be the culprit. The housing does come out with either 2 screws, or clips. Try that. Wayne

It sounds like the tension setting is too tight. The tension mechanism consists of two metal disks; the thread runs between these disks. When the pressure foot is down, the disks come together, trapping the thread between them. When the pressure foot is up, the disks separate and the thread can flow freely. (BTW, this is why you adjust the tension with the pressure foot down.)

Take a look at your tension setting and try loosening it. That should resolve the problem.

Let me know if this helps, ok?

Your bobbin is probably too loose. When you set a new bobbin, stop every now and then and try with your fingers nail if it's nice and tight enough. Not extremely tight, but tight, not loose and moves easily when you set your finger between the threads.

With most fabrics (99%) the plate is fine at the the top position, just with very thick and "fragile" (satins etc) you might need to adjust it.

Settings: Tightest tension for the thinnest materials, more loose for the thicker ones, better have a test piece, it rarely goes under 5 anyway.

I found that sewing this type of fabric you should not have any pressure on the presser foot. and the top tension should be looser but note the tension before you adjust. and remember to make sure the needle is the right size for the fabric. and since wer are not to change the bottom tension because it always right?? then you may have to make the seam stitch longer good luck

Check your tension disks, with your presser foot up, and the tension dial on zero. Sometimes a piece of cotton breaks off between the tension disks and then prevents the disks to work properly. Also make sure when you thread the machine, the thread does go through the disks and over the take up lever. After you threaded the machine, before putting the thread through the eye of the needle, lower the presser foot and while pulling on the thread with your left hand, increase the tension with your right hand. Do it slowly and you should feel in difference in tension. If this is the case, your machine should work fine. Good Luck!
