Adjusting Bobbin Tension

I have a SE270D. The bobbin thread it came with is 60wt...and costs 10.95 a spool. I would like to change over to a more affordable bobbin thread. I have tried several different bobbin threads and each time I get less than perfect results. I was told that I need to adjust my bobbin tension..but how do I do it? I'm so afraid of messing my machine up...does anyone know what I can do to fix my problem???

Thanks!!

    the bobbin gathers in several places just makes a big mess

    how do you adjust the bobbin?

  • thejaxfrog Jan 12, 2008

    I have tried to use different bobbin threads and have watched my stitch quality differ with each one. None of the stitch quality is as nice as when I am using the more expensive bobbin thread. I am specifically asking for a way to adjust my bobbin tension so that I am able to use a different, but less expensive bobbin thread and not lose my quality of design.



    Thanks

I looked forever to find this darn green bobbin screw. Around the opening for your bobbin is a plastic cover. If you slide it forward it will pop right off. Once you remove this, the bobbin case will lift right out. On the front you will see your green screw for adjusting your bobbin tension.

The bobbin screw on my se 270 D is covered in green paint. Should be easy to spot.

I notice the thread from the bobbin is loser than the one coming directly from the spool. Also, one side of the stitching seems normal and the other side seems like a long single stitch


That is tension. Sounds like you need to tighten the upper tension slightly to bring the bobbin thread up. The tension is correct when the upper and bobbin threads meet in the middle of the fabric. Also, tension will not always be constant. It may need to change as you change fabrics, thread, and as your machine ages, so it is best to get comfortable with adjusting the tension for each project.

How do I set a straight stitch? What is causing the top thread to break?


You do not say which machine you have. As for a straight stitch, make sure the needle is central and not in zig zag mode.
The thread can break for several reasons, such as. Incorrect tension.
:Wrong thread for the material.
: Thread in bobbin different from the top thread.
:Old thread.
: Not threaded correctly.
: Needle not inserted correctly, or incorrect needle.or the thread could be wound around the spool holder pin,
Try removing the spool and turn it around.
Hope this helps.

How to adjust the tension disks on my Pfaff sewing machine?


Make sure your bobbin is the right size. If it is too high it won't turn freely. Also, make sure you drop the bobbin in so it rotates clockwise. The tension must adjusted by hanging the bobbin from your hand and bob it up and down gently. It should move about one inch downward once adjusted properly. The hole in your plate should be checked to ensure the center where the thread dispenses is smooth. Use a finger nail file to smoothen if needed. Now, adjust the top tension to four. You may need to adjust just slightly. Just remember when you remove the bobbin assembly to put a drop of oil on the race. (Many forget this). When you rotate the handwheel towards you the bottom thread should come up. If this doesn't happen then you will need to have adjustments made.

Bernina artista 180 bottom stitch bunching


bunching under the material is bird nesting is a result of loose needle thread tension thread the machine up to the point of threading the needle
pull on the thread and you should have a reasonable resistance to pulling the thread
adjust the tension until you get that then thread the needle
while you may be using the tension settings if there is a problem in the tension plates area , the tension will not get high enough regardless of the indicated setting
bobbin tension can be reasonably loose
correct tension is when both threads meet at the center of the materials being sewn

How to fill a bobbin on Virtuosa 150


Put the thread spool on the vertical spool holder with a sponge pad underneath. Wind the thread off the spool and through the small wire thread guide next to the spool holder. Take the thread across the top of the sewing arm to the tension unit just next to the gap in the case through which the thread is normally threaded - the tension unit looks like the top of a shiny screw without the slots in it. Wind the thread in a clockwise direction around the tension unit once and pull the thread with a bit of tension until it slips into the sprung gap around the underside of the shiny part. Slip the end of the thread through one of the holes in the bobbin and, preferably, wind a few turns on, then push the bobbin onto the bobbin winder shaft at the right-hand end of the top of the machine. Turn the bobbin clockwise by hand a few more times to make sure the thread is 'locked' onto the bobbin and then just push the lever adjacent to the bobbin winder to the left. To wind the bobbin, you then press the foot controller and either stop when you've got enough thread on the bobbin or let it stop automatically when full. Make sure you dont go so fast that the spool rattles-around on the spool holder otherwise this could spoil the way the bobbin gets filled.

My bobbin thread keeps looping and the top looks fine but pulls out easily. I tried adjusting the top tension, but it didn't help. What can I do?


There could be several things that could cause the machine not to pick up the bobbin thread.


1. The upper thread could be tangled. Remove the thread completely from the machine. The correct size spool cap should be used for the size of the thread spool. Re-thread the machine according to the directions in the manual.


2. Remove the bobbin and make sure the bobbin is threaded properly in the shuttle race. Remove any loose threads or lint in the shuttle race.


3. You could be holding the needle thread too tight. Hold the thread lightly to keep the end from going down into the shuttle.


4. The needle could be thread incorrectly. Thread the needle eye from the front to the back.


5. The needle could be bent or improperly inserted. Install a new needle with the flat side of the needle facing the back.


If the problem persists, your machine may require service.



The bobbin thread tension has already been adjusted at the factory for general use. For most applications, no adjustment is needed.

When sewing with then thread on thin fabrics, the thread tension may not be adjusted adequately with the upper tension control dial. Therefore, the thread tension must be adjusted according to the procedure described below.

If bobbin tension is too loose and locks appear on the surface of the fabric, decrease the thread tension by turning the dial to a lower number.

If the result is still not satisfactory, then adjust the bobbin thread tension.

Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the screw more than one full turn.

Underneath stitch bad


Sometimes even though the tension is at recommeded placement, you may find with various fabrics or threads, you have to adjust it. I would try to raise the tension just a bit. Try it a little at a time until you achieve a stitch you are happy with. If adjusting the tension does not correct the problem, double check your threading. If sure it is threaded properly, especially going through the tension assembly...check your thread. I have found that the thread you use can and often does create tension problems. Try changing the thread and see if the stitch quality improves.

Need timing instruction for brother SE270d


Your needle thread lock on the bottom of your fabric and your bobbin thread locks on top. If you are getting jamming in the bobbin it is caused by the needle thread. Thread your machine with the presser foot up this will ensure thread going between tension disks.
