16. DIFFERENTIAL FEED
• Differential feed is a system which “stretches” or
“gathers” the fabric, when the amount of feed of
front feed dogs in relation to the rear feed dogs is
changed.
• The differential feed ratio ranges from 1:0.6~1:2.0.
Adjustment is made by means of the differential
feed adjusting dial pictured at right.
• Use of differential feed is very effective in stretch
fabrics.
• Setting “N” is differential feed adjusting dial setting
for ratio 1:1.
To set the differential feed adjusting dial for gathering
• Set differential feed adjusting dial above setting “N”.
Setting of adjusting dial depends on material being
sewn as well as the amount of desired gather.
Therefore set dial to suit the fabric and test sew before
sewing your garment.
Note: For normal stitching, set differential feed
adjusting dial to graduation “N”.
To set the differential feed adjusting dial for stretch
• Set differential feed adjusting lever knob below
setting “N”.
