Roll Hemming - White 7234 Instruction Book

5. ROLL HEMMING
Roll hemming is achieved by adjusting the thread
tensions so that the fabric is overiocked, 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 roil hemming.
For roil 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 4.5and 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

Upper looper thread

4 tension.
Dial

For roll hem sewing, pass the nedle thread to
the left side (solid line) of
thread

illustrated. [For normal sewing, pass
it to the right side (dotted line) of thread
guide

At the begining of sewing, gently pull the end of
the thread chain.
For roll hem sewing, pull the material gently
towards the rear of the machine, and you'll get
the neater stitches.
