Differential

7. DFFERENTAL FEED
Differential feed prevents stretching	or puckering
fabrics, since two independent feed	dogs, one in
front and one behind the needles, can be adjusted
to feed at different ratio.
This function produces a neat finish of overlock for
stretchable and lightweight fabrics.
+ “N” indicates the normal position.
