Question about Juki MO-644D Mechanical Sewing Machine

1 Answer

I have a juki mo-3614 serger and I can't seem to get the blades lined up right for cutting. It just seems to want to roll the fabric instead of cut it. How do I line up the blades the right way.

First, pull out the bvlades and make surte they are sharp. It could simply be that they are dull. Next, line tyhe bottom blade up level to the surface of the needle plate. The top blade should be adjusted to where it slices against the botom blade. You may have to experiment with the height adjustment on the top blade, assuming you have a suitable cutting edge.

Can I make rolled hem with a Juki MO 2366 N?

Most likely. Most overlockers can make a rolled hem. You will probably want to do a lot of practicing on scrap chiffon before trying it on the real thing. It involves using only one needle, both loopers, and making appropriate adjustments to the machine.

Do I have to have the cutting blades on the machine to serge material? Also, what's rolled hem and whats overlock?

No you do not need the cutting blade to serge but you shouldn't have to remove the blade it you should be able to push the knob at base of blade inward or pull it outward to turn blade downward out of the way.

TUTORIAL - How to do a rolled hem on a serger - StitchCraft - 71k - similar pages Aug 5, 2009 ... One of my favorite uses for my serger is to do rolled hems. A rolled hem is were the machine folds the fabric under a tiny bit and then stitches it.

Why does fabric get caugh on the roll hem devise when over locking

this sounds like an overlocker/serger machine you are using? if the fabric is catching on the overlocking tongue it could be a number of factors, have you lifted the top cutting blade out of the way and forgot to put it back into place? That would be my first thought, the top and bottom blade move against each other cutting the fabric. Rolled hemming usually requires the blade to be set on about 2, or middle of its setting range, the stitch finger is pulled back out of the stitching area, top looper thread is loosened off and bottom looper thread is tightened up, resulting in the top looper thread wrapping around the edge of the fabric and pulling the cut edge down under within the seam, forming the rolled hem.

I have the Janome MO644D. The seam is extending far past the edge of the fabric with really big loops. It almost looks like a tension problem, but I've tried adjusting it, flossing the thread through...

s-l300-pupyr0ualaj20obfvyre1rzh-1-0.jpg I think the right 'finger' on the plate is out too far. You may need to adjust your cutting blades further to the right until your cutting blades are in line with the right finger on the plate. Sometimes I have forgotten that I set my cutting blades for a rolled hem and then went back to regular tensions and plate but forgot to adjust my blades back to regular serging.

I want to adjust my serger yuki mo 2516n but i don't still have it's manual instructions

if you go to this page there are the current household sergers from Juki and a four page threading diagram for them showing the different stitch set ups.

If your serger is a domestic one too (the MO in front makes me think so) then you may find that the threading up is very similar on your model. Stitch length is usually a kob on the right marked from 0.5 to 4 and differential feed knob is usually there too, usually marked from -0.5 up to 1.5. Tension settings are usually around 5 but you adjust the looper tensions to suit the fabric and how wide you are trimming it with the blades.

You could contact Juki or their local distributor in your country and arrange to purchase manual for your model. this page gives a listing for countries.

it is also available on line to purchase as a black and white pdf file, for $8USD

My blades won't cut, they seem to be rolling rather than cutting

check bottom blade,it should be flush with needle plate. when you turn hand wheel by hand the top knife should be even along the length of the bottom one .the top knige is held by a 7 or 8 mm screw [looking straight at you] slacken this ,turn wheel till knife come to bdc and push the top blade against the bottom one. however if the edges of the knives are shiny or worn ,it will never cut. you can buy them relativly cheaply [eastman staples huddersfield is main juki agent].

Serger blades do not cut.

For now, it works only satisfactorily:
I applied alcohol to further clean both blades,
dried and then oiled them. There seemed to be a slight gap between blades;
the fabric was dragged into the gap instead of being cut.
