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.

I know how to open and get into my Designer Se and found the blade in part broken and not able to see hoe to reinstall the new one I have


Am guessing this is a serger. There are usually two blades in a serger (overlocker). Usually one blade can be changed by the home user, the other blade sometimes requires a technician.

Consult your owner's manual. It may have specific instructions about replacing the blades.

Overlocker Instructions


Bottom blade should be flush with the stitch plate. The top blade should pass below the stitch plate at the bottom end of the stroke.

Overlocker Bernette


If this is new it will still be under guarantee so have it checked out. It sounds like a badly aligned or blunt upper blade.
Overlockers will sometimes struggle with thick fabrics and putting something to help keep the foot level to " jump the bump" will often help, discuss that with the sleasperson too.

I need a manual for a Simplicity Easy Lock Serger SL4300. I got it from a friend and she didn't have the manual. The loops are over the top of the material sticking out to far and I do not know how...


You can purchase a manual for this machine from the following link for $US14.99

http://www.sewingpartsonline.com/instruction-manual-simplicity-sl4300.aspx

I can't see it anywhere for free download unfortunately. But you may find that looking at a manual for another 4 thread overlocker may get you started. If you try this link http://www.singerco.com/accessories/instruction-manuals you can look at the free Singer downloads,
try this link for their 654 3/4 thread model http://www.singerco.com/uploads/download/555_14sh644_654-(e_s_f)-(new-led-version).pdf
it may give you some help now.

Essentially, to change the stitch width you can either move the lower fixed blade wider to cut less fabric or tighten up the upper and lower looper threads in order to close up the stitching.

Moving the blade usually means opening up the front cover door, putting pressure on the upper blade and swinging it up out of the way. Then you can adjust the lower blade, usally by turning a knob near to it. Sometimes this knob will be marked 1, 2, 3.

Adjusting the looper tensions is done by changing the tension dial settings for the thread needing adjusting. If its a standard four thread overlocker that produces a "marrow" seam it will have two needles and two loopers, upper and lower. Generally on most overlockers, the upper looper will be the second from right tension dial and lower looper will be right most tension dial - turn up one half number to tighten, or down one half number increment to loosen, then test stitch again. The needles shouldn't need adjusting too often.

I usually start with all tension dials on 5, test stitch, then adjust from there. Some fabrics will tunnel (pull in) if the seam is too wide so you need to either move the blade to the left and trim more fabric or loosen off the loopers. Or in the reverse, like you are getting, the threads will hang off the edge.

There is some good serger information on Debbis Cosgrove's pages www.sewing.about.com but if you have never used a serger, then getting the genuine manual is probably best.

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.
