5. ROLL HEMMING
Roll hemming is achieved by adjusting the thread
tensions so that the fabric is overlocked, and
folded under to 1.5 mm in width.
It is ideal for use with thin materials.
(1) Remove the left needle. (Sew only with the
right needle)
(2) Change the presser foot and the needle plate
for roll hemming.
For roll hemming sewing, use the presser foot
marked “B” and the needle plate "B”. (The presser
foot "A” and the needle plate “A” are for normal
sewing).
(3) Set the bite width between 45and 5.5.
(4) Set the stitch length adjuster to 1.
(5) The standard thread tensions are as follows;
Dial®; Needle thread............................1 -4 tension.
Dial (3): Upper looper thread.............. 1 ~ 4 tension.
