DIFFERENTIAL FEED
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.
POSITIVE DIFFERENTIAL FEED
When set for postitve differential
Feed, 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.
NEGATITVE DIFFERENTIAL FEED
When set for negative differential
Feed, 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.
