DIFFERENTIAL FEED ADJUSTMENT
The differential feed has two independent feed dogs, one
front (A) and one rear (B). Each feed dog has an individual
feed mechanism which enables the feeding of material at a
different ratio.
Set by simply turning the differential feed control dial in the
direction desired referring to the chart. The adjustment can
be made between 0.7 (negative effect) and 2 (Positive effect).
These settings give the best ratio of feeding.
For normal sewing, the dial should be set at 1. The dial can be
reset even while sewing.
If the differential adjustment lever
is set at 0.7 the front feed dog (A)
makes a longer stroke than the
rear feed dog (B).
This has the effect of accumulating
material under the presser foot to
offset the wavering on the fabric.
If the differential adjustment lever
is set at 2.0 the front feed dog (A)
makes a shorter stroke than the
rear feed dog (B).
This has the effect of stretching
material under the presser foot to
offset the puckering on the fabric.
When sewing the very thin fabric, this setting can prevent the fabric from gathering, and can
sew out the very smooth stitch (A). The settings can also sew out the stylish stitch . In the sewing
thread knitted fabric, can show wave effect (B).
When the fabric is knitted material, the setting can prevent the fabric from stretching, and
sewing the flat stitch (C). The settings can also sew out the stylish stitch. In the sewing thin fabric,
can to gather the selvage (D).
