Cannot disengage lower looper.

I have an older honeymoon 799. Recently I tried to use it with a 2 thread rolled hem stitch that needs the lower looped disengaged. For some reason the button that one is supposed to pull out and turn to lock into the 1 space is frozen and will not change positions.

SOURCE: thread continually breaking in lower looper needle

I was having this very same problem with my lower looper . I had been using the one needle stitching all afternoon and I was doing quite nice stitching. then I decided to put the right needle back in and do some overlock stitching and guess what I spent the next two hours fighting the looper problem. I had completely re-thread this machine at least 20 times now. I decided to take the needle out and re-insert it and re-thread it one more time (right lower looper- then upper looper- right needle- then left needle) was careful to pull all threads to the back and under the presser foot for about 6 inches.
Held on to the thread, lowered presser foot and did the chaining stitch. BINGO it didn't break, tried it with a piece of cloth and Perfect stitches. I have a Babylock BL402 and used tension settings left to right
4-3-3-3 and default settings for the rest.
Hope this helps someone someday.

retime your hook with relation to your needle the hook is slightly out of time causing it to "slip the loop" the hook should hold the loop until the needle retracts forming the chain

SOURCE: I can't find my Bernina Serger 800 dl manual - how

From what I have read this manual is less than desirable. Neither is the one for the brand that I have.

You may have better guidance if you purchase and use Nancy Zieman's "Serge with Confidence". I have found it very helpful.

For the two thread rolled hem, the looper cover is used to "trick" the looper into "thinking" it is threaded.

On my serger (not a Bernina), this is referred to as a "subsidiary looper". It is a spring type mechanism that fits in a small hole at the top of the upper looper.

You use a rolled edge presser foot; right or left needle; stitch length @ normal or wider; stitch length @ 1mm for the left needle/0.5 for the right needle; differential feed @ normal; needle tension - tighten; lower looper tension - normal or looser; two thread looper cover - engaged.

Test and adjust the tension as needed before making the rolled hem on your garment.

I hope this helps.

All tensions should be on 4. Also, make sure the threading is done correctly. Or if you wish; You can contact me on other sergers for sale. "Best prices guaranteed"! rick_coccia@yahoo.com

SOURCE: I am trying to do

no, you need the blade in place and cutting to give an even cut fabric edge. Set up for a three thread using the right hand needle, take out the left hand needle. move blade over to the right so it is cutting wide. Most overlockers there is also a thread finger you need to change on the foot, or a little lever you flick to move this finger forward into the stitching area. Check this on your manual as each make is a bit different.
If you can source it, put wooly nylon thread into the upper looper (knot it onto existing thread and just chain it through, the knot should go through the looper eye fine). Now turn the tension on top looper down so it is looser and tighten up tension on bottom looper, so needle 5, top looper 2 and bottom looper about 7.

Now test serge, the fabric cut edge should be wider than the overlocking seam so the fabric rolls under inside the stitching. Adjust the two looper threads so that this is happening, you want the bottom looper thread to nest right up against the needle stitch and the top looper thread to wrap all the way around too.

Once you've got this happening, turn the stitch length down to 0.5, to close the stitching right up. On some fabrics you'll need to adjust the differential feed too if the fabric is "waving" a bit.

Uneven stitches or sometimes loose when serging could indicate that one of the tension devices is faulting, so if this machine is not new and its doing this, it could need a service. Can you get a regular smooth three or 4 thread seam out if it???

It is always good to just recheck the threading path, make sure the thread aerial is up and that a thread hasn't got caught back on the thread stand somewhere if you're getting something wonky happening, threads stream off overlocker cones through the machine so anything wrong in the thread path will throw off the stitching.

I need help in good tension for rolled hem in empisal 606D overlocker


Your owner's manual should have instructions for rolled hem settings. My Bernina manual has a the following settings:
Medium weight fabric
80/12 Universal needle
3 cones serger thread
Upper looper 3-5
Lower looper 7-9
Left needle (no thread)
Right needle 3-5
Stitch length 1-1.5
Cutting width 2-3
Differential feed N

Can use woolly thread in the upper looper, but the tension may need to be loosened since the woolly nylon thread will stretch.

How do I adjust tension on a Janome Harmony 9102D


Sounds like you want to do a rolled hem for a handkerchief edge, I do the following to create a rolled hem on my over locker. Take out left needle and cut and remove that thread. Open front cover and slide back lever for the stitch finger in the needle plate, this finger stops the fabric rolling under thread tension normally so you need to pull it back out of engagement. Your Janome may have a similar means to select the rolled hem or you may need to remove the stitch finger with a screwdriver, it varies between models.

Thread upper looper with wooly nylon and right needle and lower looper in matching colour thread. (You can go wooly on the bottom looper but it hardly shows so I never bother.) Disengage upper blade and move the fixed lower blade to the right to trim less, then lower upper blade back into position. Now tension, needle leave alone (5)' upper looper very loose (2-3) and lower looper tighten up to 6-7 and test stitch. You want the upper looper thread to go right underneath and the lower looper thread to disappear against the needle stitch. And the fabric to roll inside the stitching. Finesse tensions on the loopers until this is right, you may need to change blade position too, depends on weight of the fabric and how it rolls. Once this is right turn stitch length down to close up stitching, 0.8 or even 0.5 if you want full coverage. Thats it. You can use differential feed if you want a fluted rolled edge, nice on knits.

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.
10_16_2011_3_34_10_am.jpg

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.

What setting are the three threads set on for a rolled hem on a singer ultralock l4sh654 and what is the lever by the plate for?


Rolled hemming on any overlocker is usually achived the following way. Right hand needle only.
Blade over to the right usually to cut wider than normal but you can vary this to suit the fabric and stitch width you want.
Thread in this needle and the upper and lower loopers. If you can source any, use woolly overlock thread in the upper looper, this fluffs out when not tensioned and covers the fabric to give the look of solid stitching. Change upper looper tension to about 2 and lower looper tension to about 6 or 7.

The lever by the plate is usually to control the little stitch finger where the stitches are formed, move it backwards and it should move back towards you?? If this happens, then you want it in the retracted (towards you) position for rolled hemming so the stitching is much smaller and the fabric can roll. Normally this stitch finger holds the fabric firm for the loopers to form the stitch over for your normal 3 or 4 thread overlock.

Now test stitch and see how it looks. Tighten the lower looper thread so it lays right beside the needle on the underside. You may need to then tighten or loosen more the upper looper, you want the upper thread to wrap all the way around to the underneath against the lower looper thread and needle.

The cut edge of fabric should roll to underneath inside your seam. Once you've got this happening, turn the stitch length down to 0.5 or so to close it right up tight. This uses heaps of thread so I usually test everything else, then close it up at the end to minimise waste.

Hope this makes sense, good luck.

I cannot get the tension right? Also, trying rolled hem with 3 needles...tension too loose.


Rolled hem would be one needle and two loopers, is this what you meant?

Make sure you move the blade to right so that you are cutting wider than the stitch being formed, you want the fabric to roll to the underside inside the stitch.

I would set top looper tension to 3 and bottom looper tension to 6 first off (needle at five, normal tension) first off and test serge with the stitch length at normal 2 or so, so you can see if the fabric is rolling under for you. There is proabably a stitch finger in the throat that you need to change too, sometimes its on the foot, (change with a screwdriver) and sometimes just a finger down on the needle plate.

Then adjust the two looper tensions making lower thread nestle up against the needle on the bottom of the stitch, and the top looper thread wrapping right over to bottom as well. Once this is happening, then turn stitch length down to close up the stitches.

It does depend on the weight of fabric too, and if you want to seam curves.

I find its best done with wooly overlock thread on top looper to "fill" in the overlocking appearance and fully cover the fabric.

I hope this is of help, if the tensions just wont behave then one of them might be faulty and machine need a service, I get mine done at least every 2 years to keep timing and tensions right.

Need settings for Simplicity easyLock SL370 rolled hem. Machine belongs to a friend who recently moved and the instruction manual has gone missing. Thank you!


narrow 3thread seam, so remove left needle. loosen top looper tension to 3 or 2, tighten bottom looper tension to 7 or 8. thread top looper with woolly overlock thread and reduce stitch length. there is also a thread finger u need to flick back on throat or needle plate usually to make rolled hem. also move blade to right to trim less fabric as you want the fabtic to roll under inside the seam.

What is the settings for rolled hem using your overlocker


You haven't specified your overlocker make and model but some parts of the set up will be the same; you still need to consult your machine manual to find out the changes needed to the foot. Bernettes have a little switch near the blade that you flick to change how the stitch forms so it rolls.

You need a 3 thread overlock with the right hand needle (I'm assuming you have a 4 thread lock) turn the stitch length down to 0.5 so it is very closed up. And there is usually a little thread finger on the foot that needs to be changed or a switch you flick to move it back.

Then lower the tension down on the upper looper so this thread goes over the edge to the underside and tighten up the lower looper dial so this thread lies against the needle stitch.

Move the blade to the right so the fabric is cut wider than the seam that the threads are forming so the cut edge rolls underneath and is encased in the threads.

It is best to use wooly overlock thread on at least the top looper so this "fills" in the rolled edge.

If you visit you-tube and search using "Rolled Hem" or Nancy Zieman you should find some helpful videos too.

How do I shorten the stitch to make a rolled hem? Please help.


For the rolled hem: the needle is in the O2 or right position, the length is 1.5 in the rolled section- you will see this, if you look on the side of the bottom knob- you can decrease this to 1, but you have to stay within the rolled section, the width is 3.5. the stitch selector is on D, the upper looper selector is UP, the blade is engaged and the subsidiary looper is to the right. You can use a decorative thread in the upper looper- Madeira Decor, Superior Threads made for bobbin work, or YLI Pearl Crown Rayon- or use a wooly nylon for excellent coverage and not need to decrease stitch length. I usually don't need to change the length with these threads.

Rolled hem or rolled edge


You need to disengage the cutting blade by openingfirstly opening the front and left hand side covers. pull on the larger of the two silver knobs and slide the red lever towards you. I'm not sure what the tension settings are, but I'm certain you need to reduce them a fair bit to aid in the rolling effect. I only use 3 threads when doing a rolled hem.
My description isn't too detailed but I hope it helps!
