Verify the bobbin has been installed and threaded correctly through the bobbin case. Confirm the bobbin is installed turning the correct direction. Install a brand new needle.

Why has it stopped working?


Most of the time if the bobbin won't engage is you are not making a connection as its has a certain way it goes on. Most New Homes are proprietary on how the different parts engage. If you look and not think too hard take your time, you will discover the proper way to get the bobbin to engage.

How do I keep my sewing machines top thread from hanging up on something under the plate?


Hello
The description seems to indicate that the top thread has no to very little tension. Try rethreading the upper thread and make double sure that it is engaged in the tension assembly AND goes through the take up lever (that is the little 'thingy' that goes up and down really fast as your are stitching).
Generally loops on the underside are caused by loose thread on the top.
Happy stitching

My shuttle came out and dont know how to put it back.


Hold the bobbin case with open side towards you. The thread should unwind on the top of the bobbin from the left. Place it in the case so when the thread is pulled into the slot in the side, the bobbin rotates clockwise. Pull thread to the left under the tension spring and fit case and bobbin over the central spool inside hook assembly. With the locating finger in its recess, press case home and it will lock into position with a click..

How to wind the bobin on a singer 7050


To get that same thread onto the bobbin, you'll need to windit. Here are the steps:1. Removethebobbin from the sewing machine. If your machine has a free arm, you'llhave to remove this first. Open the bobbin door to reveal the bobbin case, forvertical loading models. If your machine has a drop-in bobbin (horizontalloading) you may have to simply slide the metal plate open, which sitsunderneath the presser foot.2. Lift the latchand pull the bobbin case out of the machine (for vertical loaders). Butfor drop-in bobbins, simply lift the bobbin out of the housing.3. Tip the bobbincase over and let the bobbin fall into your hand. (Some bobbin caseshave a latch on the side, that when lifted releases the bobbin). If the bobbinhas another color thread on it, use a new bobbin. Or, if it's not too muchthread, roll it all off and reuse the bobbin. Just make sure the bobbin youwind begins empty. (But in a pinch, you can wind a new color thread over theold color. Just know that you may have to rewind the bobbin fairly soon, as thedesired color thread finishes faster.4. Place yourselected thread onto the spindle and insert a holder over it, if there is one(usually on horizontal spindles only). Many machines just use gravity toretain the thread, so if your spindle is vertical and you have no such part,don't worry about it. If thisis a brand new spool of thread, you may need to free the end. Look for a smallnotch on one end of the spool. You may have to peel back the label a bit to getat it. Then yank it free.5. Loop the free endof the thread over the bobbin tensioner and any hooks on it. Thelocation of this part varies, but it generally looks about like this. Thread the end of the thread through the pinhole in the top of the bobbin. 6. Press the bobbinall the way onto the bobbin winding spindle. Make sure any springs orclips engage. Put it on so that the end of the thread that you put through thepin hole sticks out towards you (or sticks up, depending on if your bobbinwinder is at the top of your machine). 7. Disengage theneedle mechanism. Many machines have this control in the handwheel. It may require a push, pull or twist of the middle of the hand wheel.Check your sewing machine manual to be sure. The sewing machine may run fasterwhen winding a bobbin than when sewing and you don't want the needle moving upand down wildly. Engage the bobbinwinding mechanism. On some machines, it's done by pushing the bobbinspindle over to one side. You may also need to move the stitch selector to abobbin winding position.8. Hold the free endof the thread and, keeping fingers clear of all moving parts, press the footpedal or knee lever. The bobbin spindle will turn. If you have thebobbin threaded correctly, the bobbin will wind smoothly, evenly, and snugly,with perhaps a slight bulge in the middle. You should cut off the end of thethread you were holding in your hand (very close to the bobbin) as soon asthere's enough thread on the bobbin to hold itself in place so it won't slipout. This will prevent this thread from tangling onto any moving parts.9. Fill the bobbincompletely. It may seem like a lot of thread, but you don't wantto run out too soon while you're sewing. Many machines have a built-in deviceto stop winding when the bobbin is full, often a small blade that automaticallycuts the thread when the wound bobbin is full. If your machine has such adevice, let it tell you how much to fill the bobbin. If not, fill the bobbin nofurther than its edges. Hold the bobbinand case so that they are oriented as shown. Check that thebobbin will unwind in the correct direction. If not, flip it.10. Insert thebobbin into the bobbin case. Pullthe thread under the bobbin tensioner (a thin metal latch). The threadshould advance with a little resistance when you pull at it. Allow this excessthread to just hang. Lift the latch onthe bobbin case and hold it as shown.11. Insert thebobbin case into its housing. Make sure it is all the way engaged (youshould hear it click into place) and that the direction is correct. The bobbincase shouldn't spin and shouldn't come loose when you release the tab. Itshould be locked in. And the loose end of the thread should hang free. Do notclose the bobbin door.12. Re-engage theneedle at the hand wheel, disengage the bobbin winder, and set the machine backtoa straight, forward stitch. Thread the machine with the top thread as usual. Once the threadis through the needle, you must raise the bobbin thread. Hold the end of thethread with your free hand. Turn thehand wheel towards yourself. The needle should go down and back up to itshighest position. One full rotation should do it. The top thread will passaround the bobbin.13. Watch as the topthread pulls the bobbin thread up through the hole in the plate under thepresser foot. Pull the looseends to extend them, and continue to hold them firmly so they don't get tangledas you begin to sew.Closethe bobbin door before sewing.Hope this will help you. Good Luck.

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.

Bobbin thread won't engage.


The bobbin case is not in the shuttle.

Raise the needle to it's highest position.

Lift the lever on the back of the bobbin case and hold it open as you insert the case into the shuttle; arm on the case pointing up. You may have to turn a bit to the left or right - it will click when in place.

Installing the hook and bobbin assembly.


The plastic bobbin case should sit on top of the raceway, it should slot in quite easily, once the bobbin case is in put the small metal clip at the top over to hold it in place.

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.

I need to thread an elna air electronic su sewing machine


that's a nice machine, one of the last mechanical Elnas with the discs for extra stitches. Firstly, you need to wind a bobbin, always use Elna swiss metal bobbins, with holes on one side only, slightly dished. Put on top of the bobbin spindle and take the thread from your spool on the spool holders at the back of the machine across to the tension disc on top left, its white bump, thread through the tension then back to the bobbin and pull the tail through a hole in the top of the bobbin. Flick bobbin across to the right against the stop, disengage the clutch by holding the outer flywheel and turning the inner towards you. Now press the foot pedal to start winding a bobbin, holding the thread tail so it starts off. Wind one full coverage of the bobbin so that the starting point is covered, then stop and cut the tail off with scissors. Now continue winding at 3/4 speed until bobbin is full, watch as it winds and give the thread a nudge with your finger so it fills top and bottom as well as in the middle of the bobbin. When it is full, the bobbin spindle will stop winding. Move it to the left, cut the thread and reennage the clutch by holding flywheel and turning the inner the other way. Now install the bobbin and click the thread into the tension device, see image.

Now thread up the top thread by taking the top thread from the spool, through the tension discs, across to the eyelet on top, down to the check spring, back up to the take up lever, then down to the needle catching the thread into the two thread guides enroute.
See this image.
10_6_2011_6_43_20_am.jpg

Now thread through the needle front to back, hold the top thread, close the bobbin cover leaving the tail sticking out the top, lower the needle down by turning the flywheel towards you through one cycle and pull the top thread, drawing the bobbin thread up to the top of the needle plate with it. Pull both threads under the pressure foot to the back and your ready to go. Remember, top tension should be on 5 and bottom tension should be on the red 1, don't change it. Brush out the bobbin holder assembly each time you use this machine and add one drop of oil into the middle of the bobbin holder, there may be a red dot or just the indenation. Run the machine for 30 seconds after oiling without thread, slowly to spread the oil through the bobbin mechanism. Standard 130/704H needles, change regularly (6 hours of sewing) and pick right sized needle and type point for the work you are sewing. Good luck with your SU. If you wanted to join, there is a Yahoo group called "Elna Heirlooms" for fellow Swiss Elna owners.

Needle wont go up or down


If the Handwheel (big knob) is moving but the needle is not moving, you need to engage the clutch ........depending on the model

- push handwheel in to engage, pull out to disengage
or
- if there is a smaller wheel inside the handwheel, tighten to engage, loosen to release.

BUT if all is jammed........

Check for threads that are jamming the motion of the hook around where the bobbin case is

If your bobbin goes in from the top, remove the needleplate and bobbincase remove thread jams by gently rocking handwheel back and forth until released.

Clean around the hook race with a rag moistened with methylated spirit, surgical spirit or similar, then reassemble.

If front loading, open the door for bobbin case area, release 2 retaining clips holding the collar on (take note of the position/orientation for when you re-assemble....even take a digi photo to refer to !?!).....
......then just do jam removal & clean out in much the same way as for the top loader.

In all cases, don't force too much or be too brutal, gentle and patient works best, try to judge where the jam is caught and work with it slowly......you may need to cut jammed threads, just ensure all are removed before you re-assemble.
