16. DIFFERENTIAL FEED
Differential feed is a system which “stretches” or
"gathers” the fabric, when amount of feed of front
feed dog in reiation to the rear feed dog is changed.
The differential feed ratio ranges from 1 :0.7 ~
1 : 2.0. Adjustment is made by means of the
differential feed adjusting lever pictured at right.
Use of differential feed is very effective in overedging
stretch fabrics and fabrics cut on the bias.
Graduation “1.0” is differential feed adjusting lever
setting for ratio 1:1.

sieeves, yokes, front and back bodices, skirt hems,
etc. in stretch fabrics such as knits and jerseybefbre
assembling into garment.
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 stitch length 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.
Note: For normai overedge stitching, set differential
feed adjusting lever knob to graduation ”1.0".
