Question about Brother LS-2125 Mechanical Sewing Machine

3 Answers

Timing I believe my timing is off because when I go to sew fabric, the spool thread gets all looped up where the bobbin is. It does not correctly grab the bobbin thread, so I end up with a loopy tangled mess around the bobbin area. Any suggestions on timing?

    Here is some more information:



    When I sew a piece of fabric, the top thread is the one that is all loopy underneath and I end up with about five loops before my machine jams. It grabs the bobbin thread, but not continuously I don't think. I will try what you have given me, but please let me know if anything else works. Thanks!!!

    I did try what you have said. I'm not sure what is going on. It did help a bit, but it still does not sew the bottom thread.

    This sewing machine is about to go out the window! I have tried every possible solution I have found on the internet and nothing is working! I'm having the same issue...I sew for maybe about 4 stitches and its getting stuck in the bobbin area. I know its not the machine because my mothers did the same thing on me... what am I doing wrong? I've checked to make sure the needle is in correctly..rewound the bobbin...made sure it was threaded correctly ( a million times)...adjusted the tension...anything else I can try?

    Question: How does one find the tension discs??? I have a White 1740 with a top drop in bobbin and I went thru the same problems as night_wolf above, then, ultimately, the top thread will now not pick-up the bobbin thread through the fabric. It picks up the bobbin thread without fabric in play, but once fabric is added (for free motion quilting) it won't pick it up. This is after using the machine for the last 10 days to piece and quilt without a problem until this morning.

    I'm at a loss.

This happens to me and when I look at my bobbin, the thread is coming out the side instead of the top of the bobbin case where I threaded it - like it came out. When I put it back it will work, but then it happens again adventually. I think I am not threading it properly.

My stitch wont stay in the fabric what am i doin wrong


needle thread tension worng
no thread in the bobbin
neeld /hook timing is wrong

Most of the time the bobbin stitch is correct. Occasionally there is a loop in the bobbin thread. Any suggestions as to what this could be?


Is it actually the bobbin thread that loops or is the loop appearing on the underside of the fabric as you stitch? If it is a loop under the fabric, that's usually an indication it is an upper thread issue. Thread irregularities that appear on the topside of the fabric are generally bobbin related.

First thing to try is installing a brand new needle. Verify it is the correct needle for the fabric and thread being used.
All About Needles
Sometimes, the fabric being stitched will "grab" the thread and hold it for a second before releasing and will cause a loop. In this case, a needle with a larger scarf and eye may be helpful.

You might also open the upper tension as much as possible, RAISE the presser foot and run a piece of UNwaxed dental floss through the tension disk a few times to clear out any gunk that may be stuck there. A piece of pearl cotton dipped in rubbing alcohol and squeezed moist/dry will also work.

Remove the upper thread. RAISE the presser foot and rethread the top thread from the beginning. Use only fresh, good quality thread--NO old or bargain bin variety! Try using the same thread in the top and bobbin. Make sure the thread is firmly seated in the tension disk and the thread path is correct. Check that there are no burrs or snags in the thread path that could be catching the upper thread. Especially, check that the thread is not catching on the spool "slit" that holds the thread when in storage. Every time the thread navigates around the thread spool, it could be catching on that slit just enough to cause a loop.

Try changing the bobbin. There could be something amiss with the current bobbin--could be nicked or could even be the wrong bobbin for the machine. Also, make sure the bobbin is loaded and turning the correct direction in the machine.

Set the upper tension to the midway point. This is usually the starting point, although it will probably require some tweaking. Test your stitch and adjust the tension so the upper and bobbin threads meet in the middle of the fabric. Neither thread should dominate one side of the fabric or the other.

Understanding Thread Tension Threads

Last thing to try is a different presser foot.

If you still have the intermittent loop, you might want to take it for service. Could be a problem within the tension disk.

How do I adjust tension on a Necchi Lydia 510 sewing machine?


loops under fabric means top tension needs to be tightened
try cleaning the top tension dial with some unwaxed dental floss and see if that helps. if it doesn't then the tension dial may need to be replaced
also check to make sure the spool of thread is not getting caught on the spool holder
also try a new needle--one that is correct for the fabric being sewed

Have you tried a new needle? Needles should be changed out before each project and if a large project, several times during the project.

My Husqvarna diamond top thread keeps breaking while doing loop embroidery. It sews a couple of stitches and then you can hear when the thread breaks. Ive tried changing the needle and bobbin, and cleaning...


Hello

Primary causes of upper thread breakage:


-- misthreading: pull all the thread off and thread again, using the manual, step by step. Read each step aloud before you do it. (sounds dumb, but helps.) (And make sure you thread the takeup lever!)

-- thread has wrapped itself around a thread guide or spool pin from one of the breaks. Take the spool off the machine before rethreading.

-- bad or damaged needle. Replace with the right size for the fabric, turned correctly (backwards needles skip stitches)

-- dirty machine, especially in the bobbin case area: review cleaning instructions and do it, using brush and vacuum only

-- bad/cheap thread: should not be slubby or break easy. Try another spool.

-- top thread tension too tight. 4 is normal for most fabrics, most stitches.

Tips;

1) do a light cleaning (brush and vacuum) every day you sit down to sew.

2) replace the needle if you hear it hit metal, if you've got a really bad thread jam, if you see it deflect as you sew (for instance, sewing over the side seam on jeans when hemming). Replace every 3-8 hours of actual stitching time anyhow.

3) buy good quality thread

4) when your machine isn't sewing right, stop; take all the thread off of/out of the machine (bobbin out of bobbin case, spool off spool pin) and give it a quick cleaning. Rethread from scratch, carefully. If that doesn't fix it, do it again, then replace needle and rethread one more time, manual in hand (yah, even if you've threaded it 8 million times before). #4 is curative about 98% of the time. The other 2% often requires professional attention.

How do i thread my needle with the singer handy stitch?


  1. Loosen needle screw & insert needle with shank's flat side facing front of machine. Push needle in all the way, then tighten screw to hold needle in place.
  2. Install a fully wound bobbin by loosening bobbin nut & placing bobbin on top. Re-attach bobbin nut & tighten. If standard thread spool will be used, then attach spool pin to bobbin shaft & place thread spool onto shaft. Attach white spool cap on end of thread spool, then tighten. Bobbin/spool should unwind facing forward toward needle.
  3. Bring end of thread through thread guides & over tension control. Pass end of thread through needle eye, from back to front, & pull it out about two inches.
  4. A spring pushes pressor foot onto fabric that is being sewn, so lift pressor foot & place fabric underneath.
  5. Turn large handwheel on side of machine (handwheel can be turned in either direction) to raise needle arm to its highest position.
  6. Holding the Handy Stitch in place with your right hand, press on power switch & begin sewing. Guide fabric (being sewn) with your left hand.
  7. To end this sewing session, turn off power. Turn handwheel to raise needle to its highest position. Carefully pull out about three inches of thread through needle & snip, then lift pressor foot to remove fabric. Turn fabric over & loop needle threader through last stitch. Place end of thread from underside through eye of needle threader, & pull to loop through. Pull to tighten and snip end of thread.

Bobbin thread loops


If you threaded the machine with the presser foot UP and the thread from the bobbin is feeding from the spool in the correct direction and through the guides on the bobbin case and the loops are still forming, then the machine needs to go into the shop as the timing may need to be adjusted and this is best done by a sewing machine technician, preferably Brother.

No matter which direction I turn the tension, I have big loops


If you threaded the machine with the presser foot up and the is bobbin inserted so the bobbin thread is feeding from the bobbin spool in the correct direction and through the guides as indicated in the manual, then there is a possibility that the timing needs to be adjusted by an authorized Brother tech.

Can't pull thread from spool


The sequence of setting up of thread from spool to needle is not complied to actual setting is one factor to be consider it affect the sequence timing of sewing.Particularly some machine are common in starting up threading.fig. shown a basic flow of thread on red color.It maybe a helpful oneb1934dc.jpg

In addition to this the set up of thread to bobbins winder is also need in right place the thread should be in clockwise rotation when coming out to bobbins casing as shown in fig.76e4431.jpg as you can see when thread was pulled out from bobbins winder is moving counter clockwise.If you try to sew, try cotton fabric and set dial to # 3 to 4 and stitch set range to 8 up to 12 depend on layers and thickness,After setting try to sew manually ,turn hand wheel by your hand first,let upper tension catch the lower bobbins tension and arranged thread and insert fabric use hand turning hand wheel several time until stich appear on fabric observed loop thread on lower bobbins on fabric.if accumulation of loop thread on lower adjust upper tension also dial tension gradually until it has a smooth stich appear.

Janome Sew Mini bobbin problem


Hi, Usually wrap-ups in the bobbin area are caused by the lack of tension on the top thread. The slack arm ( shinny lever that moves up and down while sewing) has to pull the loop around the bobbin case and it does so only if the tension on the top thread is sufficient to keep it from pulling more thread of the spool.
Try this: Thread the top of the machine all the way just short of the needle eye. When the presser foot is up the thread should pull through easily. Now drop the presser foot (this closes the tension discs) and pull the tread while adjusting the upper tension control.
If everything is working correctly you should feel the drag on the thread change if not something is keeping the discs from closing.
Most Janomes aren't too difficult to remove the nose cover, usually just one screw and you can get a look at the thread path. Look for thread wrapped around the mechanism.
Sorry, no easy answer but I hope this helps.
