Differential feed*
Differential
feed·
j ,
There are two feed dogs: one front
and one rear. The two feed dogs
move
independently and the
distance each feed dog
travels
during one complete movement
can be adjusted.
Stretching effect
To stretch the fabric
select a
number from N to 5
in
the
section "
c:::J
".
This prevents fine nylon jerseys
or
closely woven fabrics from
puckering.
Pushing effect
To prevent
waving or to gather
select a number from N to 8
in
the
section " 0
".
This prevents waving or fluting
in
knits or puckers
in
fine woven
fabrics.
It
also can be used to
gather
single layers of fine woven
fabric.
Note:
When sewing without
differential
feed the dial should be on
position N.
Gathering·
Use the differential feed to gather
a
single layer of fabric. For exam-
ple sleeve heads, yokes, lace edg-
ing or
frills.
