• ADDITIONAL INFORMATION ABOUT
ROLLED HEMMING
* Hold the thread chain when you begin sewing to
keep it from curling into the seam.
* Place a slight tension on the material in the sewing
direction and a finer seam finish can be obtained.
* The minimum overedge stitch width that can be
obtained for rolled hemming is approximately 1.5
mm (1/16 inch) since the cutting width cannot be
set below 3.5mm (9/64 inch).
• TO SECURE THE ROLLED HEM THREAD
CHAIN
* Apply a small drop of liquid seam sealant to the
end of the seam. Allow to dry, then cut the chain
close to the stitches.
Note:
Test the liquid seam sealant for color fastness
before use.
