Where can I find what the rolled hem attachment looks like, costs, and where can I find it? Can i find it still?? I checked the Bernina Bernette 234 on the Bernina website and even the online manual they have for the Bernette 234 doesn't talk about the parts numbers or name.
What's a babylock serger and how is it different than other sergers?
There is no need for a rolled hem attachment as it is built into the machine.
If you look just under the needle, you will see a silver stitch finger that can be moved back and forth using a lever on the right side of the needle plate. When you pull this lever toward you, the finger pulls back so that the stitch will be formed around just a narrow pin. When you serge, usually using a short stitch length and a high tension on the lower looper, the thread and a small amount of fabric is rolled around this pin forming the rolled hem.
So: 1. Pull the lever towards you. 2. Remove the left needle so you are using only three threads. 2. Turn up the tension on the lower looper so that is is just a tight chain on the bottom of the fabric. 4. Shorten the stitch length. 5. Sew a test and set the differential feed so that the fabric doesn't pucker.
The 234 also does a 2 thread rolled hem. To do this, you need to install a small wire part onto the UPPER looper, slightly changing the thread path. The two thread rolled hem is then sewn using only the upper looper and the right needle. Sorry, I cannot remember the tension settings for the 2 thread rolled hem. (I used to sell these eons ago but I own the earlier model that doesn't convert to 2 threads.) But experimenting a bit will tell you, though I think that it should be in your manual
Good luck with your rolled hem.
I have a Bernette MO-234, and it *does* require changing the needle plate to do a rolled hem, pl;us there's a little doohickey mounted at the top right of the machine which increased the tension on one of the looper threads, can't remember ATM which one.
If OP needs the plate and/or tension thing, maybe Ron can help? I ordered one locally from a SAVE store.
