Differential feed
Differential feed is a system that
stretches or gathers the fabric by
changing the amount of feed of the
front feed dog relative to the rear
feed dog.
The differential feed ratio ranges
from 1:0.7 to 1:2. Adjustment is
made by using the differential feed
adjusting lever pictured.
Using differential feed is very
effective for overedging stretch
fabrics and fabrics cut on the bias.
The graduation "1.0" is the setting
for a 1:1 ratio on the differential
feed adjusting lever.
Gathered overedge
Gathered overedge is most suited
for shirring sleeves, yokes, front
and back bodices, skirt hems, and
other parts in stretch fabrics such
as knits and jersey before
assembling them into garments.
To set the differential feed
adjusting lever
Set differential feed adjusting lever
knob below graduation "1.0".
Setting of adjusting lever knob
depends on material being sewn as
well as the amount of gather
therefore set knob to suit the fabric
and test sew before sewing your
garment.
When feed regulating dial is set at 3
or over, the amount of feed of the
main feed dog will change to "3"
automatically when adjusting lever
knob is set to 2.0
