On my elna supermatic 722010 sewing machine, the thread makes the bobbin pop out and the thread get tangled underneath. I have had it fixed twice, which is expensive. Should I just get rid of it and buy another machine?

Hi Beverly,
My suggestion is that you join up the Yahoo group called "Elna Heirlooms" you'll find lots of very helpful fellow supermatic owners there and probably what you are looking for too. Here is one page from the manual for threading the bobbin into tension, once you've mastered this on the Elnas, its the same for all the Swiss ones.


Yes, top threading is important, you need to get the thread into the tension discs and also the take up lever. Have you cleaned out the tension discs too? these do get gummed up with fibres and dye particles sometimes. Just turn tension down to zero and "floss" between discs with the selvage edge of a clean piece of waste cotton fabric.

Might see you over on Yahoo, several of the members there are really knowledgeable on these great machines.
cheers

Drop in a full bobbin with the holes side upwards (I'm assuming this is a Swiss Elna sewing Machine horizontal bobbin design as you haven't given the model number).

Now, hold the thread tail with your right hand and pulll the thread clockwise towards you while holding the bobbin still with a finger from your left hand. Bring the thread tail around towards you until it goes into the little slot, then press downwards onto the thread tail close to the bobbin until you hear it click into the tension spring. Test by lifting the thread tail upwards, it should stay in tension and not come back out of the groove.

Now close the back slide cover over the bobbin leaving the bobbin thread tail visible out to the right.

Now manually turn the flywheel towards you while holding the top thread tail and take the needle down into the bobbin holder area and back to the top, pull the thread tail to bring the bobbin thread up to the top.

There is a threading up diagrams at www.sewusa.com http://www.sewusa.com/Threading_Diagrams/Threading_Pages/Elna_Sewing_machine_threading/Elna_Supermatic_threading_diagram.htm
for the old Supermatic but the bobbin holder design is almost identical for all the subsequent models such as the SU, TSP, Supermatic or Air Electronics like the Stella, Carina or Jubilee, the above is the same for all.

A link to a supermatic manual is here
http://www.arizonaexpressionz.com/elna_instruction_manuals/Supermatic.pdf - I suggest you download this and print it out as this machine is over 50 years old now and manuals are scarce.

Disengage the clutch by holding the outside of the fly wheel and turning the inner knob of the wheel towards you.
You need to take the thread from the spool across to an eyelet on top left, then back to the bobbin winder, up through a hole in the top of the bobbin and hold the thread tail. Flick the bobbin across against the stopper. Now press the presser foot or knee control to start the motor. Hold the thread tail until youve got coverage across the bobbin enough to hold the start, then stop winding and cut the thread tail with scissors. Now continue winding but put the handle of your scissors on top of the thread spool to stop it bouncing and ensure your thread winds smoothly and under tension.

Watch the bobbin fill and give the thread a nudge to fill top and bottom as well as the middle evenly, you want a nice even wind. Fill to 3/4 and stop, flick bobbin back off the stopper, then cut the thread. Remember to re-engage the clutch by reversing the first step.



This is a lovely heirloom Elna machine - you need to thread the bobbin as the manual describes and get the thread into the tension spring. Please read the manual information on oiling too, this machine needs to be oiled on the red spot locations every time you use it according to the manual, use good quality clear sewing machine oil for this purpose.

www.whitesewingcenter.com has the manual for an Elna 722010.

I have a Elna Supermatic 1954 sewing machine. What is the proper way to upperthread?

Elna Supermatic 722010 is a very vintage elna and would take the metal 7 hole dished bobbin like this.





Don't try to use any other bobbin in it, and always load and wind with the holes on top.

You can still buy these; one supplier is sewingpartsonline, here is like to the item

Try the usual eBay route, but also approach any Sewing Repair shop as they often acquire odd bits from old machines....We had 9 disks for a lady with an Elna SU only last week, all from a machine traded 2 years ago and really beyond resale.
