Question about Sewing Machines

1 Answer

On my Babylock Serger, the upper looper seems to get stuck when it meets the right needle. I've replaced the needle thinking it was bent.But it still gets caught in that position.I haven't used the machine in a year, but today I sewed one seam, which worked fine. Then it ''jammed'' and won't work since.

This is a timing issue and for an overlocker, really beyond the scope of anyone not trained or familiar, it is a 3D ballet between the loopers and needles and needs to be finely balanced to exacting tolerances I'm afraid to say.........the cost of replacement of each looper is around the price of a service......so..... Strongly recommend you to take it to a service centre for adjustments.......you will break more than a needle if you persist.

How to replace a lower looper on my babylock bl4-428d serger


Yes, but it's not a do it yourself job for most people, as the timing will have to be redone.

How do I set up my babylock serger for a rolled hem? What is the tension to be set at?


I don't know your babylock well, some of these have automatic tensions and electronic stitch selection. But a rolled hem is achieved on any overlocker in the following way; the actual dials and knobs might vary a bit.

Firstly there is a stitch finger that you need to change or retract so that the thread can roll the fabric rather than staying flat. For a normal seam this finger sticks out in the area where the loopers and needle form the stitch holding the cut edge flat until the seam is made over it. But for rolled hems you want to retract this finger so it does roll.

On the Bernettes this is a little lever in front of the stitching area that you pull back to retract the finger. Have a look around where the stitch forms and you should see the finger. Some machines, its a part you change on the needle plate with a screw driver, or just move a switch or lever.

You want the right hand needle in place, remove the left hand needle.

Thread upper looper with wooly overlock thread, this is a fluffy nylon that pulls flat under tension but relaxes and "fills" out once its stitched into place. Gives that lovely covered look you see on shop bought tablecloth edges. Your regular thread in needle and lower looper. Usually cutting blade to the right side as you want it to cut more fabric than in the seam so it rolls under. Now loosen off the tension on the top looper, (I use 2 on mine but this is something you need to finesse with each machine), and tighten up the tension on lower looper, (about 7). Leave needle tension alone.

Now test stitch on your fabric, and finess the upper and lower looper tensions until you get the lower looper thread almost not showing, it should be right up against the needle on the underside with the upper looper thread completely wrapping around top and bottom, pulling the fabric under.a seam like this.

Test stitch and adjust upper and lower looper until this is happening.

Now, turn stitch length down to close up the stitching, probably 1 or 0.8 if you want a real satin stitch look to the hem.

Because of the stitch density this uses thread so do the finessing first, then turn the length down.

That's it! Now right down the tension settings you used and keep handy for next time.

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.

I require operating instructions as to what is requiered for flat bed stitching?


I can share the information for my BabyLock Imagine in hopes that it will help you.

There are options of 2 or three threads.

For the 2 thread the serger must have a 2-thread converter- aka, auxiliary looper or subsidiary looper.

This is a spring type mechanism that fits in a small hole at the top of the upper looper. It 'tricks' the upper looper into thinking it is threaded. It must be engaged by connecting to a small hole in the upper looper

Set up the serger for a 2 or 3 thread right or left needle.

Stitch width - wide if you are using the left needle and normal if for the right needle; length 1 - 3mm.

Needle tension loosened and looper tension normal.

Disengage the cutting blade..

Set the differential feed at normal.

Hope this will help.

I need a replacement manual for Babylock Xscape BL66


You will need to contact a BL dealer to order a manual, if any are available. This model has been replaced.

There is a threading guide in on the inside of the door on the front of the serger.

Raise the presser foot and set the tension controls to zero.

Turn the handwheel until the upper looper (curved looper) is at it's highest point - there may be a mark on the side of the serger and handwheel for aligning to this point.

Thread the upper looper first, then the lower looper, then the needles.

Pull the threads under the presser foot and to the left side of the serger.

Set the tensions back to 4 - 6 setting, lower the presser foot and stitch a chain before serging fabric.

You may be able to find a free manual download at the Brother website for a similar product.

BabyLock Proline upper looper thread keeps breaking


I ended up switching the spools of thread around. Apparently, even though I had purchased good quality threads, one of the spools was wound in a way that made the thread loop and twist around. So I put the offending spool of thread through one of the needles and put the needle thread on the upper looper. That seems to be working. By the way, BabyLoc was very unhelpful dealing with this problem.  Thank you!

Threading a husqvarna huskylock 1001L serger


Solution taken from "Handbook for Huskylock Sewing Machine Models 1001L/1000L/1000"

1. Raise the presser foot by using presser foot lever. When the presser foot is raised, the two thread tension discs in the thread tension control panel are released so that thread passes freely between them. Otherwise thread tension may not be correct.

Important! When threading the needle, always be sure to lift the presser foot lever, and also take care to thread in the proper order.

Threading order:
1. Upper looper thread (green)
2. Lower looper thread (blue)
3. Double chain stitch looper thread (purple) in case of 5 thread stitch or double chain stitch
4. Right needle thread (red)
5. Left needle thread or double chain needle thread (yellow)

Caution!
Because the left thread tension dial (yellow) is used for either the left needle or the double chain stitch needle, these needles will never be used at the same time.

Upper looper (green) sequence:
1. Thread holder (silver triangle openings attached to thread holder stand)
2. Thread guide (flat silver clips just behind thread tension disc)
3. Thread tension disc (circular knobs with numbers for tension setting)
4. Pull thread around upper looper guide and upper looper
5. Pull thread into hole of upper looper

Lower looper (blue)
Repeat 1, 2, 3.
4. Pull thread around guide (see color coded chart inside front serger cover).

Easy threading mechanism (for lower looper)
1. Pull out the lower looper threading lever
2. Thread the lower looper and position the thread on hook of the lower looper
threading lever.
3. Push the lower looper threading lever back to its basic position while
holding the end of the thread.

Caution:
When returning the lower looper threading lever, always make sure that the two
blue triangle marks (directional arrows) meet each other.

Right needle thread (red)
Left needle thread (yellow)
Important: Thread the needles after threading of lower looper and upper looper.
First raise the presser foot lever, and then thread the needle threads in order shown in color coded thread guide.

Probably your looper timing is off. This is common, and just a necessary evil of sergers. Their tolerances are tight.
The operation of creating a serger stitch is a succession of thread grabing and delivering. One looper grabs a thread and delivers it to the needle and so on.
To check this, turn your handwheel slowly and check to see that the upper looper is meeting the lower looper by passing very close to the indented part at the back of the lower looper (indented part is called the scarf, this is where the looper threads form a lock) If not, it's the looper timing. If they seem to meet properly then check your needle. Is your needle up into the needle clamp all the way? Try a new needle. Even a slight bend to the needle will not allow the loopers to meet and grab or deliver thread. You might check the tensions. Thread has to have some resistance in order for the loopers to do their job,

If your looper timing is off, find a sewing repair person to retime the serger. Don't try it yourself or put this repair off. If the loopers go further out of timing, they might hit something and replacement can be costly.
