Question about Consew 206RB

1 Answer

Thread loosens underneath intermittently. Stitches not consistent.

I get loops on the underside of fabric no matter how loose or tight I set the tension. I cleaned the tension discs, replaced the bobbin,needle,and cleaned around the feed. I just start sewing and it starts to loosen on the  underside of fabric then tightens up etc.

    IT SEEMS FROM VIEWING PROBLEMS THAT THREAD TENSION IS A BIG PROBLEM WITH THIS MACHINE. I HAVE HAD IT IN FOR REPAIR AT LEAST THREE TIMES FOR THIS SAME PROBLEM. wOULD LIKE TO JUST REPLACE IT RATHER THAN PUT MORE MONEY INTO IT IF THIS IS A RECURRING PROBLEM. PLEASE ADVISE

    It skips threads and won't catch the threads on the underside of the material. I haven't sewn in years and can't remember how to fix this. Would it help to have a ball needle on, as the fabric is thin and slippery?

Bottom thread seems too tight!!! Help!!!


If the bottom thread is tight there should also be loops on top and this means that the upper tension is too tight.
Get out your manual (http://www.singerco.com/uploads/download/1198_8763-efs.pdf) and turn to page 24. Under "ADJUSTING TOP THREAD TENSION" it tells you that if you're having thread tension issues, change the tension control dial on the top of your machine from auto. It also shows you a diagram with your problem illustrated on the right side of the page. The bobbin tension is set at the factory, so all tension problems can be solved with top tension adjustment. Set it manually and if it loops on top, loosen the tension a little. Test again. Repeat until loops are gone.
Using different colours on top and bobbin and a contrasting fabric (e.g. black top, white bottom, light blue fabric) means you can easily see what's happening. A perfect stitch is when you see exactly the same stitch pattern on both sides of the fabric. On top, the bobbin thread colour appears between stitches as a tiny dot and on the bottom, you see the top thread dot between stitches.
If it's impossible to get the tension right, take it to a technician, because it's a sign that the hook timing needs attention.

Underneath of quilt the stitches are long with smaller topstitches is my top tension to loose or too tight


YOur top thread is looping, right? Re-thread your top thread, making sure you floss it into the tension system. When you drop the pressed foot it should offer tension to the thread. Right? When you have underside loops it would indicate too much thread, right? So either the tension is too low OR something is jerking on the top thread causing a loop.

Singer 2517c. When sewing, the bottom stitch is using to much thread, excessive amounts & the stitch isn't tight. I've tried all settings & have used a new bobbin. I'm at a loss......


Your description isn't very clear. When you say the "bottom stitch is using too much thread" Do you mean you see lots of loopy threads on top of the seam? Or do you mean you see loops on the bottom under the fabric? If your loops on the bottom, that means the top tension is too loose, you've not remembered to put the presser foot down, you have not threaded the top thread properly... Start by rethreading carefully with the presser foot UP. Then do a test stitch, remembering to put the presser foot down. If you still get loops underneath... tighten the tension.

If your loops are on the top of the fabric. loosen the top tension... then do a test seam... and if you still have loops loosen again and repeat. If you start to see loops on the bottom... tighten the tension a bit.

Good luck

The bobbin thread is loopy on the under side of the fabric. I tried adjusting the tension setting but it didn't help at all.


Loops stitches on the underside is typically from the TOP tension being too loose, however it can also be the bobbin tension is too tight, or a problem with the needle. I would check them in that order.

Hold the bobbin thread and let the bobbin dangle. A slight shake of your hand should allow the bobbin to move downward (lets more thread out) but not so much that it just drops to the floor. When you put it in again and try sewing look at the top stitches. Do they look overly tight? THen the bobbin tension is too tight. The stitching should look the same top and bottom with no loops.

If both tensions seem to be alright check to see if the needle is: 1. the right size and type of the fabric 2. not bent

That should fix your problem :)

Stitches are looping on the underneath and missing some stitches


Refer to the manual for cleaning.

Replace the needle with the size recommended for the type of fabric being sewn. The flat side of the needle is usually facing the back of the machine - check manual to be sure.

Always thread any sewing machine with the presser foot up. This opens the tension control so the thread can properly enter this device.

When a sewing machine is threaded with the foot down, the tension control closes and the thread cannot enter as it should

You then get loose stitches because the top thread and bobbin thread cannot make a proper stitch and the tension of the bobbin thread is pulling the top thread to the underside of the fabric.

How do i adjust the tenion on my bobbin thread?


There should be a screw on the bobbin holder. This screw is on the side of the bobbin casing. (Bobbin holder removes to put the bobbin into). Most models have this. Turn the screw clockwise to increase tension. Run a stitch and check the underside of the fabric to see the stitches. If they look loose or sloppy still, turn the screw more, if they look too tight(pulling) then you have gone too tight. Hope that this helps!

THREAD GET BUNCHED UP UNDERNEATH THE FABRIC, THE STICHES SEEM TO BE INCOMPLETE THE TOP LOOKS GOOD THAN I TURN IT OVER AND THE THEAD IS BUNCHED AND LONG LOOPS OF THREAD ARE LEFT. THANKS LOU


Hi Lou! This sounds like a tension problem--the tension on the top thread is too loose. Try using different color threads on the top and bobbin, then carefully rethread everything. Stitch a couple of inches and check the underside. If the top stitches look fine and the bottom ones are loose and loopy, and with the pressure foot down, tighten the tension. Move the knob or dial (whichever you have) just a little bit. Sew a couple of inches more, and recheck. Continue to sew and recheck, gradually tightening the tension, until you see little if any bobbin thread on the top or top thread on the underside of the fabric.

Let me know if this helps, ok?

Viking Designer 1 balleds / Birdnest / issues after repaired from Husk service center in midwest - replaced thread needle and adjusted tension .. freequilting and embroidery situations


birdsnest refers to a mess of thread on the underside of fabric when you start sewing (after a few stitches all looks good). if this is the case and it is happening during embroidery, switch off jump stitch thread cutting.

if it happens at the start of normal sewing, either hold your needle thread when you start sewing or make sure the needle thread is under the presser foot and held by the presser foot when you start sewing. this way you will have an inch or so of thread on top of your fabric which you can trim instead of a mess underneath.

if there is a mess underneath for more than first few stitches, either your check spring in the needle tension area is set incorrectly, or your needle tension is set too loose (adjustable in sevice menu by tech only) or there is foreign matter caught in tension assembly preventing proper tension.

BOTTOM STITCH IS ALWAYS LOOSE


If the top stitch is loose, then you need to tighten the bobbin tension: if the bottom stitch is loose, tighten the top tension. Hope this helps. It could also be the size needle and thread you are using for a particular fabric. Different fabrics require different notions.
