Question about Brother LX3125 Sewing Machine

1 Answer

This machine will sew properly & then start giving me a loop stitch on the bottom stitch. The top stitch looks good. Have changed tension with the wheel that shows stitch length, etc. This sometimes fixes the problem. What causes this.

You might check your bobbin case tension---turn the screw to the left to tighten----to the right to loosen
also after every project check the needle to make sure it's in good condition

The thread for the top needle just sews and loops onto the lower thread


I think you are saying that there is a loop showing on the bottom of the lower thread stitch. If the lower stitch looks correct and not bunching, you will need to change the tension on the upper stitch. Make sure that your threads are firmly inserted within the discs also before adjusting the tension. It doesn't take much to change the tension so take it slowly.

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

Thread tension


try changing the needle first--make sure the needle is the correct one for the fabric being sewed.
if you've adjusted the top tension & the bottom stitch still looks the same
it's possible that the top tension dial is needing to be checked to see if it's
working correctly

I have a singer 7258 that I can not get the tension to loosen up on. The top stitch is straight across and adjusting dial doesn't help.


Hello

Adjust the tension

Load your sewing machine with one color on top, threaded through the needle. Load the second color thread into the bobbin and thread.


Fold the scrap fabric in half, and sew a straight stitch at least 2 inches long. Look closely at the seam. If you see loops of the bottom color thread on top of the fabric, proceed to Step 3. If you see loops of the top color thread on the bottom of the fabric, proceed to step 4.


Loosen the top tension. Since the top tension is so tight, it is pulling the bottom thread up through the fabric. Loosen the top tension by turning the numbered knob on the front of the sewing machine counterclockwise by one number.


Tighten the top tension. Since the top tension is too loose, the bottom thread is pulling the top thread down through the fabric. Tighten the top tension by turning the numbered knob on the front of the sewing machine clockwise by one number.


Sew a straight stitch 3 inches in length. Check the stitching. It is perfect if the threads meet in the middle, and you can only see the top thread on top and the bottom thread on bottom. If it still needs adjusting, go back to step 2 to repeat the needed steps.


Using two different colored threads makes it easier for you to see which thread is being pulled.

Always use proper precautions when working with electrical machines.

There is one way out. Give the sewing m/c a thorough servicing job, Clear all the pieces of cloth/fabric/threads, etc Remove the bobbin and load afresh. Clear out the toothed sliders which pulls the cloth while stitching. the thread being used for stitching passes a sort of loop, the tension being controlled by how much the pressure the spring can exert such that depending on the material being stitched. Specially after stitching satin, which is tricky material to stitch in a sewing m/c since the cloth is slippery. Also clear sewing jam and the metal teeth like rack which pushes the cloth for the next stitch to start. This area if cleaned up properly and a little bit of oiling on the spring loader and the spindle assembly which moves up & down...............................sudeep
