My Singer 14u44 serger machine is just cutting fabric and not sewing, I have checked the threading and tensions twice.

Probably due to incorrect threading or else one of the needles are bent. I had the same problem and it was the threading and the tension.frustrating as all get out.

It is difficult to tell what exactly is happening with your serger.

First thing--make sure you RAISE the presser foot BEFORE you thread any of the threads. This releases the tension disks so the threads will seat properly. You may need to remove all the threads and rethread from the beginning, making sure you thread each in the proper order. Start out with the thread tensions set at the ideal setting--usually the halfway point between the high & low numbers. From there, you will adjust them to even up the thread tensions.

Are you actually trimming off some of the fabric as it is stitching? If so, you might try increasing the cutting width (moves the cutting edge further toward the right) so that there is more fabric caught within the looper threads. It also appears that the looper tensions may be too loose. Try tightening the upper and lower looper tensions so less of the thread loops don't fall off the fabric's raw edge.

I try not to pull the threads when removing my fabric from the serger. Instead when the fabric has cleared the needles, continue to sew a chain of about 5-6 inches, then simply cut it with scissors leaving part of the chain attached to the fabric and the rest of the chain attached to the machine.

you might have the serger checked for a timing problem
Serger thread breaks


1. Is the serger threaded correctly?


2. Is the needles inserted correctly?


3. Is one of the needles bent or damaged?


4. Is the tension adjusted too tightly?


5. Is the tension adjusted to accommodate thickness of thread being used?


6. Are you using inferior quality thread?


7. Is the thread feeding of the cone/spool freely?


8. Is the needle size correct for the type of fabric being used?


9. Are the needles being used the correct one for the serger?


10. If all of the above suggestions don't help then the serger needs to be checked for a timing problem at a sewing machine repair shop.

I would suggest that you contact Husqvarna Viking to purchase a manual for your 936 serger, their contact details are here.
http://www.husqvarnaviking.com/us/406.htm

You could also get lots of general sewing info from Debbie Cosgrove at http://sewing.about.com/od/sergersoverlock/ss/serger.htm sewing.about.com is a fantastic source of information on sewing techniques, sewing machines, sergers and projects too.

Sergers are quite differernt to a sewing machine and there are plenty purchased, used once or twice, then put away or sold because they are a bit difficult. But like any new skill learnt, taking a class and learning hands on is so much better than trying to figure out from a manual so if you can find a local Husky dealership, I'd enquire about an "intro to serger" type class, well worth the money and time.

Yours will probably do a three thread overlock, 4 thread overlock and rolled hem stitch, these three seams will cover a variety of sewing tasks and applications. You can seam knits and lycra with the 4 thread, and neaten the raw edges of just about all fabrics with a three thread. The rolled hem allows you to do a small covered edge which covers the fabric cut edge wrapping the thread around it closely. Beautiful on very light weight fabric edges like ruffles and frills where you have yards of fabric to neaten, much quicker than turning edge twice and straight stitching it.

There are other techniques with a serger such as sewing stretched elastic onto fabric, sewing over nylon fishing line to give a fluted edge or stitching over a string of beads. These are best done with a special foot for this purpose, elasticator or beading foot. You can also use decorative threads through the loopers to give an attractive finish.

There are several good sewing with a serger books on the market, Singer does one but there are other great ones too. You could always borrow one from the library before committing to buying it.

Have you changed the needles in your serger before this happened?

If so, check again that the left needle is fully up into its housing and that the needle is in the right way with the scarf (cut out) at the back. Have you got a ball point needle in one side and not the other perhaps. If you are seaming knits, then put in 2 ball point needles, if for wovens, then two sharp needles.

Now check tension on left needle, is the number on the dial the same as the right needle. Pull on the left thread just after the tension disc then the same on the right thread, does the tension feel the same on both?

Is the thread catching somwhere on the aerial, caught on the cone holder, or at the back somewhere or as it comes through the tension discs? Take thread out of the discs, turn dial to zero and give between the discs a good clean with the selvage edge of a clean piece of cotton waste fabric, saw it back and forwards to clean out the discs. Now thread the machine again again. I'm assuming this is a 4 thread serger, so thread order would be top looper, bottom looper, then right needle, left needle, turn tension to zero on all threads, pull all four threads out under the foot, loower the pressure foot, turn tension back to five on all (or whatever your normal setting is) then chain off a little and test sew.

I hope this helps resolve your issue.

no, retiming a serger i cannot explain. needs to be done by trained sewing mahcine repairman sorry

Here is an easy way to get your thread adjusted. Rethread the machine using four different colors. Then sew and for example the "yellow" thread is loose on the fabric, you know to adjust the tension with the yellow thread. Also a good starting place on your dials is 4-3-2-1 from left to right. Start with the tension set there and then adjust as needed.
