Differential feed*
There are two feed dogs: one front
and one rear. The two feed dogs
N
move independently and the
distance each feed dog travels
during one complete movement can
be adjusted.

section "

closely woven fabrics from
puckering.

a single layer of fabric. For example
sleeve heads, yokes, lace edging
