Try to keep an even speed, do not go too fast because it always seems to wind uneven. I had to learn not to do that.

My SE400 is not winding the bobbin thread evenly. What is wrong?


I'm not sure that any of my machines thread the bobbins evenly, even the newer ones. When winding, I just use a stylist, pencil, or other item to move the thread up or down to fill the bobbin evenly. Also, do not thread the bobbin on a fast speed. Slower will be less likely to stretch the thread and will give you better opportunity to evenly thread.

Tip

Winding a bobbin correctly


The heart of sewing is producing a well tensioned seam and achieving this with any sewing machine will be difficult if you don't wind a bobbin smoothly and with even tension onto the thread. If you look at your bobbin and the thread on it looks all lumpy and uneven, then this tip is for you.

Each time you wind a bobbin, whatever sewing machine it is on, it is really important to keep even tension on the thread as it winds onto the bobbin. Many machines will have a little tension disc you take the thread around but your technique is important too.

Usually you take the thread from your spool of cotton on the right, across to the left on the top of the machine and around a tension disc, or through a thread eye, then back to the right to your bobbin winding spindle, if your bobbin has holes in it, then pull the thread tail up through a hole and pop it onto the spindle. Engage the spindle by pushing across against the stop. Now start winding SLOWLY while holding the thread tail up in the air until the core of the bobbin has been covered in fully and your thread has covered up the starting point to hold the beginning tail. Stop winding, and trim the tail off against the bobbin with a pair of snips. Now resume winding at 1/2 to 3/4 speed and do two things, one with each hand. With one hand put tension onto the top of the spool you are winding thread off - use the curve of your scissors handle into the indent on top. And with your other hand, give the thread a nudge as it winds onto the bobbin to ensure you wind fully across the whole bobbin evenly. Watch it carefully to ensure that you get a smooth even wind.

An analagy: if you wind the garden hose onto the hose reel really fast and let it go anywhich way, the hose will kink and wind mostly in the middle then the reel's full and you've still got half the hose to put away. Thread is the same, its been wound onto a spool by a machine in a very precise way; you want the same smooth evenly tensioned winding onto your bobbin so that when you stitch out the seam the thread is consistently fed off the bobbin.

Don't be tempted to wind flat out and just let it take its own path as you won't get good smooth bobbins of thread. And if you let the thread come off the spool at a fast pace the spool may bounce around, causing fluctuations in the tension on the thread. When you stich a seam, the thread will relax unevenly in your seam causing puckers and ho hum stitching.

Simple stuff but it makes a difference!

Bobbins wind unevenly- tension issues


Sounds like it is actually the tension on the bobbin winder. Make sure that the thread is following the correct path to the bobbin. Other than getting it repaired, a stand-alone bobbin winder (avlb @ JoAnn's or online) for ~$30 would work. One brand is called the Sidewinder. Verify that your bobbins will work on it because some Singer bobbins will not. It's a nice accessory to have because it saves wear 'n tear on your machine plus you can wind bobbins without unthreading the machine.

FWIW, it is usually better to wind bobbins at a slower speed. Higher speed will tend to make the bobbin jump around and the thread to pop off. In addition, higher speed will tend to stretch the thread going onto the bobbin. The thread will not relax until unwound from the bobbin and stitched into your garment. It may cause the fabric to pucker as the thread relaxes. Slower is better!

I have a new Bernina 350 and the bobbin doesn't wind on evenly. If left to do it automatically it ends up wrapped around the bobbin spool. Is this normal?


the thread has to be pretty tight around the bobbin tension guide
but I would suggest if you can't get it to wind correctly to have it check to see if there is a problem with it

I have an elna airelectronic tsp machine & cannot thread bobbin. Please help


Firstly, have you got an Elna metal bobbin? it should be solid on the bottom and have 7 holes on top. It is essential that you always use it this way, wind it with the holes on top and load it into the bobbin holder the same way.

Have a look at the image above, you need to load the bobbin in and click the thread into the tension spring so it doesn't lift back out when you pull the thread upwards. There should be an audible click as it goes in.

If you can't get it right or this image is just too small, feel free to email me and I'll send you the image and talk you through it, I have a TSP machine too. cwrogers@tpg.com.au.

Also, check my tip on bobbin winding here http://www.fixya.com/support/r10598580-winding_bobbin_correctly it is important to get a good even tension onto your bobbin as you wind the thread on, you may need to manually add some tension to the thread as it winds off the spool, as I've described in my tip. I sold these machines for Elna and customers would bring them in complaining of problems with their machine. Almost aways, it was the needle in backwards, bobbin upside down, thread/lint buildup in the bobbin race or badly wound bobbin that was the problem.

Hope this helps you Gaylene, but if not, please email, I may be able to send you the relevant manual pages.

Loose boobin winding


You need to ensure that the thread is going from the thread spool at the back of the machine, through the eyelet, then around the silver tension disc on top of the machine, then to the bobbin when you are winding it. Also, pull the thread tail up through the hole in your bobbin to start and hold the tail so the thread starts to fill smoothly and doesn't loosen.

I've marked the disc in red on this image

Please read my Tip on bobbin winding; its really important to get a good wind and you can add more tension yourself by applying gentle pressure to your thread spool on the back pin as you wind off it.
Link is http://www.fixya.com/support/r10598580-winding_bobbin_correctly

The stopping when full is possibly because your bobbin is winding unevenly but I never run it until it stops itself anyway, and do the winding at 3/4 speed, not flat out. You want a really smoothly tensioned even wind onto the bobbin so your thread comes off the bobbin when stitching with even tension, not stretched, then loose.

Hope this helps you with your problem.

My elna sewing machine bobbin won't spin on top to wind thread around. The fly wheel spins though...I've been putting thread on the bobbins by hand.


If the fly wheel is going around then the clutch isn't disengaged to wind the bobbin, you need to pull out the flywheel on your model to disengage the clutch for bobbin winding.

Take thread from thread spool across to bobbin winder thread guide, then back to bobbin and thread the tail through the hole on top of the bobbin. Place bobbin onto spindle on top of machine and then push it against the stop to engage the bobbin winding motor. HOld the thread tail up and start winding slowly until the bobbin core has been covered including the starting point. Stop and trim off the thread tail with scissors. COntinue winding bobbin and give the thread a nudge if needed to wind evening top middle and bottom of the bobbin. A good smooth wind is important. Also don't wind at full speed and keep an eye on the thread reel that the thread is coming off, you don't want it bouncing around as this will **** the thread and stretch then relax it affecting your bobbin wind.

Obviously if you know this and the bobbin winding mechanisim is just not working, then it will need a service/replacement by an Elna repair person.

The bobbin thread keeps breaking! It is very loose and then snaps?? I've replaced the needle to make sure it was sharp, I bought the highest grade thread I could find, adjusted the tension... then...


Sounds more like the way the bobbin has been wound, is it loose and uneven or tight and smooth. Is it properly into the tension spring? being loose doesn't sound right, a thread under correct bobbin tension is usually pretty firm.

Is it loaded into the bobbin holder the right way ?

Also check the bobbin itself hasn't been damaged in some way, not worn/bent. It needs to turn smoothly in the bobbin holder so if one edge has been bent a little this will cause problems.

When winding bobbins, you must have tension on the thread so it winds smoothly with consistent tension on the thread. Most machines have a little tension disc on top or the thread goes through the regular tensioner in order to achieve this. But I always wind bobbins at about 3/4 speed and also add a little extra tension by holding my scissors handle on top of the thread spool so it doesnt bounce around. Also start winding with a little tail pulled through a hole on top of the bobbin and wind until this starting end is covered, then stop and snip off the tail. Then continue winding and watch the thread, giving it a nudge so that it fills evenly across the bobbin, not just all in the middle.

Think of it like the garden hose reel; if you wind it really fast the hose all goes into the middle of the reel, then jams up and you can't get the whole hose onto it. Same thing, wind smoothly and evenly across the whole depth of the bobbin so that the thread is smooth and even. Then when the thread feeds off it will be smooth evenly tensioned and should stitch out evenly.

There is some good trouble shooting information on this page too which might help you to work out what is causing this thread breakage.

Bobbin stich is uneven and a tangled mess


you can dowload a manual from the singer website http://www.singerco.com/accessories/manuals.html

If the bottom stitching is uneven, its mostly the top thread not under tension correctly so check the tension dial and the threading up from the thread spool to the needle.

Also, review how you wind a bobbin, you want a nice smooth wind, not twisting or uneven build across the bobbin. The manual for this machine is pretty brief on this but bobbin winding is crucial to getting a good even flow from the bobbin when stitching seams. You want to wind thread smoothly onto the bobbin, across the full width of it, not just mainly in the middle. Give the thread a nudge with your finger tip to fill top and bottom as it winds.

Also, ensure the thread goes through the bobbin tension disc on top of the machine, and even then, use your scissors handle to put some downward gentle pressure onto the thread spool you are winding off so it doesn't jump or bounce as you wind. Wind the bobbin to 3/4 full, then stop.

And lastly, load the bobbin correctly following the manual directions, make sure it is turning the right way in the bobbin case. Also look at page 16, it shows the "dangle" test where you can check the tension on the bobbin case is right, you should be able to dangle the bobbin by the thread tail and it should "stay" but you should be able to pull on it to release thread too. Adjust the little tension screw in minute increments to get this right. Bobbin case tension springs can fail or break too, so check this out.

Hope this helps you; it is my experience that 90% of machine issues are caused by blunt or wrong sized needles, wrong threading, no tension or incorrect tension or lack of maintenance.

Bobbin won't wind correctly!!


Iam very picky about my bobbins!

make sure you are threading the machine for the bobbin correctly, In my opinion I don't think any machine really winds well.

What I do is hold the thread about an 1" away from the bobbin. start to wind and I guide the thread slowly up and down the bobbin so that it winds even
