SOURCE: i have an 1130 bernina

The 1130 does not have a consumer adjustable presser foot. Check to be sure you are using the correct presser foot .Some feet are slightly different in height which is how the pressure is regulated. If this is not your problem it will need to be seen by a technician.

SOURCE: skip stitch

The three most obvious causes (other than that of the machine possibly being slightly out of time) are:

1) Too small of a needle size - increase the size.

2) A needle that has a flaw / defect - change the needle.

3) Needle not inserted correctly, either not pushed all the way up into the needle bar, or not installed facing the correct place. On this machine, the small "scarf" in the needle (an indent just above the eye) shouldface the right side of the machine.

I would like to know how to set the machine up for polyester/spandex material


You need a ball point size 70 or a jersey 70 if you can get it. Stitch length 2.3 to 2.5. Re tension, just normal tension setting. If the machine is sewing an evenly balanced zigzag on regular cotton fabric, then tension is fine. If you find the straight stitch on your fabric pops under stretch, then try using a very small zigzag to put some flexability into the seam.

My Juki MO-655 serger will sew a few inches then the needle thread becomes disengaged in the stitch process. The machine will sew a few inches more then stops making stitches. I have cleaned the thre


Make sure you are threading the machine correctly. Make sure you are using serger thread that isn't old. Make sure you are undoing all the threads when it breaks and thread it from the beginning.

Make sure you have the right needles in their respective places. My Juki MO has two different size needles.

Juki MO-634DE Stiching


I tried to find this on the Juki website but its obviously a previous model so not much info on there. But did find it listed elsewhere as a 3/4 thread overlocker.

So I'd guess at the following, it probably seams a four thread marrow (overlock seam) made with two needles and two loopers. And a three thread overlock seam where you use either the left or right needle, this would give you either a narrow or wider 3 thread seam. Image below of 3 and 4 thread overlock seams.

Lastly, I would suggest that the D denotes Differential feed, this is a feature that controls the two feed dogs in the machine and gives you the ability to set them to move at different speeds - very handy to control the fabric feeding but also used decoratively for lettuce edging.

Rolled hem - most overlockers of 3/4 variety will also do a rolled hem; however, I can't actually confirm if this model does or not. But look around for a retractable stitch ****** in the foot or needle plate or a second needle plate in the accessory case. Rolled hemming is also very useful and most models will do it now; just variation in how you actually set it up to do so. Bernettes you flick a lever in front of the needle/foot area, earlier Elnas like the L3 and L4 you needed to change the needle plate and a little ****** in the presser foot.

Of course, you could email the local distributor for Juki in your country and ask them and this may be the best way to check. Just copy this into your browser

JUKI MO 134 SERGER


How to Thread Juki MO-134 Serger from watching lady at Lyles. Turn upper blade up. Push in first then turn up.It makes threading easier. Blue Thread upper looper first. Pull thread through tension knob. Don'tjust lay it there. (She thought that is what I must have done) Orange Thread lower looper next. Pull thread through tension knob as inthreading upper looper. Adjust lower looper so it is right nextto upper looper so that their points are almost together and directly belowsewing needles. Lower looper will be in front of upper looper (I believe). With tread from upper looper pulledback, slightly lift lower looper above upper looper and thread. I think this isright. Pull thread back with other thread. Tension is the key. Remember that. Yellow: Thread left needle first.Remember tension. Pull thread through curled wire on left side of needle arm. Green: Thread right needle. Rememberabout tension. Pull thread through curled wire on right side of needle arm. b> Note: Before sewing turn the wheel tomake sure the stitches are going together correctly.

How can I use this machine as a MERROW machine ?


For best results, use Maxi-Lock cone thread.
Remove the left needle.
Slide the stitch forming finger towards you, away from where the stitch forms.
Set the stitch length to around 1.
Set the needle tension 4 or 5.
Set the upper looper tension at 4.
Set the lower looper tension at 7.
Adjust the stitch width, if needed.

I have a Juki MO 3716 and I cannot thread it. Please help. It has four threads.


I also own a Juki MO3716. It is a five thread not a four as it has three lower looper threads. Two are fed through the front, just follow the color codes and the threading diagram on inside plate that you lower to see the threads, the third is threaded through the back and around the left side. I can send email with picture of diagram if needed. the other two threads are for the two top needles. This machine is a true safty stitch with the overedge row of serging and an inner chain stitch row for secure seaming. You can run this machine quite nicely with only three thread ( one inside needle and the two front loopers. If you need further held email me at wanmacinnes@eastlink.ca

Coverstitching on White Speedylock serger


Your machine cannot do a cover stitch. Check the Brother website, they make a cover stitch only machine, it works much better than any of the serger/cover stitch combination machines, and it is a lot less money.

2nd needle/4th thread - threading confusion


With some sergers, but not many (singer 14u64 comes to mind), the top of the stitch will be an overedge that mates with the right needle thread, and the left needle thread will appear as a separate straight stitch. When you look at the underside of the stitch, the overedge will go all the way over to the left needle (the full width of the stitch). This is normal if you have this type of machine. Another stitch some sergers do (2/4 thread sergers) is a 2 thread chain thal looks like a lone straight stitch on both sides, and a 2 thread separate overedge.

As far as the threading of the takeup, it totally depends on your model. Always post your model number when you have questions as sergers vary greatly in design.
