Try using a can of air in the bobbin area, also check for lint or loose threads, make sure the bobbin is turned correctly in the bobbin case, try a different bobbin.

    I have cleaned the bobbin area, put a new bobbin in, changed thread, needle, fabric and adjusted tension. Any new suggestions? Thank you for helping!!

  • Debbie Dec 03, 2014

    I know this may sound silly but make sure that every thread guide is used, the last thing I would suggest is the machine may need the timing checked

  • Debbie Dec 04, 2014

    try this--When you thread the machine, do so with the presser foot up.

    go to youtube they have some video's,,type in top thread winds around bobbin and see if one will help you.

A few things to check. Is the upper thread caught? You can test the upper tension, that could be pulling up the bobbin thread, by putting a size 80 needle in the machine. Put the presser foot down and pull on the upper thread it should bend the needle about an 1/8 inch when the tension is at 5. Also check the threading is done correctly and not catching on a thread guide.

Pfaff 2046 tension problems, needle breaks


Needle breaks
1.the needle is damaged
2.the needle is not correctly inserted
3.wrong size needle for the fabric
4.the wrong foot is attached
5.the needle clamp screw is loose
6. Top tension is too tight--loosen off one letter or number till the stitch
looks normal
7.make sure that every thread guide is used when winding the
bobbin,, so that the bobbin will wind tightly, if this doesn't help,,
then it's possible that the bobbin winder needs adjustment,, it needs
to be taken to a sewing machine shop

The thread keeps coming off the needing when i sew


Hello

I would suggest that you revisit the threading up in your manual and double check that the top thread is under tension.

However, if the stitiching on top of the fabric is wonky, this is your bottom tension too loose, and if stitching on the the underside of the fabric is loose, its the top tension causing it.

Quite often bobbin winding can be the cause of bad stitching so pull out the manual and wind a bobbin carefully following the instructions, making sure that the thread is under gentle tension as it winds. What you don't want is for the thread spool to bounce around as it unwinds onto the bobbin as this gives uneven tension of the thread and when you then stitch a seam, the thread relaxes in different amounts causing puckering.

So wind at 3/4 speed, and gently guide the thread onto the bobbin so it fills evenly across the whole core. And ensure there is tension on via a tension guide if your machine has one. If not, then place the curved handle of your scissors onto the top of the thread spool and hold it there as you wind, which holds the spool down and keeps the thread coming off it smoothly.

Always raise the pressure foot when you thread the machine so the top thread goes into tension fully. And new needle for each new sewing job is really important, make sure it is the right size and type of needle for the fabric you are sewing.

Hi, my problem is my bobbin. The tension is fine, it is when I put the bobbin into the bobbin holder. When I thread it through the plate with the top thread, it is so hard to pull out. It seems really...


TENSION: As you change projects and start sewing on different weight materials, you should test stitch on a piece of scrap material of the same weight before beginning the actual project so you can adjust your upper tension to that particular fabric. As an example, if you're changing from a denim type fabric to a silky fabric, you would definitely want to make sure the tension is correct and the stitching looks right before you start to sew the garment.

To determine whether the upper tension is too tight or too loose for the fabric you're wanting to use, try the following test. Take a small scrap of the fabric, fold it, and stitch a line ON THE BIAS of the fabric, using different colors of thread in the bobbin and on top. Grasp the bias line of stitching between the thumb and the index finger. Space the hands about 3 inches apart and pull with an even, quick force until one thread breaks. If the broken thread is the color of the thread in the needle, it means that the upper tension is too tight. If the broken thread is the color of the bobbin thread, the upper tension is too loose. If both threads break together and take more force to break, it means that the tensions are balanced.

BOBBIN: The most probable cause of the lower thread breaking is an improperly wound bobbin. Regardless of where you wind the bobbin, inside the machine, on the top of the handwheel or on the front side near the hand wheel, the basic "bobbin" rules apply.

** Always start with an empty bobbin. Never wind one color over another color.
** Don't wind the bobbin so full that it would be tight and hard to insert into the bobbin case. Most machines have an automatic "shut off" when the bobbin gets full, but if yours does not, be careful not to fill it too full.
** Wind the bobbin evenly across and in level layers.
** Never mix different sizes of thread in the bobbin and on the spool, unless you're doing sewing machine embroidery or some specialty type of sewing. Using different weights of thread on the spool and in the bobbin for general sewing will cause ragged stitches as well as other stitching problems.

NEEDLE: Probably 25% of machine repair jobs I go out on, the only problem was that the needle was put in backwards. I know you're probably saying "I've been sewing most of my life and I know how to put the needle in the machine"; however many times a seamstress will get in a hurry and not give the needle a second thought when putting a new one in the machine. If your machine will not pick up the bottom thread or skips stitches badly, in most cases it's because the needle is in wrong.

Each sewing machine requires that the "flat" side of the needle be put in a specific way - facing the front, the back, etc., depending on your particular make and model. If you have a sewing machine that takes a needle that doesn't have a flat side, you'll notice that each needle has a groove in it where the thread lays as it penetrates the fabric. Depending on whether your machine shuttle system faces to the front or to the left, the groove of the needle will also face front or left.

MACHINE THREADING: An additional area to check for stitching problems is whether the sewing machine is threaded properly. Each machine has a certain sequence for threading, and it only takes one missed step in the sequence to cause your machine to skip stitches. If you're in doubt, take the top thread completely out and start all over again.

Just got my used Bernina deco 650 from the shop. Tension off


The tensions are not calibrated properly. To get by, or if you do not want to take it back to the shop, just lower the upper tension a little at a time until it looks ok.

Bernina Deco 650 Top thread is winding around the bobbin


You should use some klnd of stabilizer under your hoop. I use the paper kind which is thin or there is a heavier tear away stabilizer. I have used all cotton thread for embroidery or you can use rayon. There is a finer thread called bobbin thread for the bobbin but I gernerally use the same as on the top so it will be the same. Are you using an embroidery needle? .As for your thread getting wound around the bobbin the only thibng I can think of is tht it is threaded incorrectly. if it isn't the lack of a stabilizer. I hope this helps but I think it the the lack of stabilizer that is causingyour problems. The needle is going in and our of the same hole during embroidery and is getting stuck on your bobbin. Let me know if this helps! Suz
