Differential feed
There are two feed dogs one front (C) and one rear (D). The
two feed dogs move independently and the distance each
feed dog travels during one complete movement can be
adjusted. The differential feed prevents fluting or waving in
knitted or stretch fabrics and movements between the layers
of fabric. It also ensures pucker-free seams in smooth fabric
such as nylon or closely woven fabric.
Perfectly at seams in knits or stretch fabrics.
The distance travelled by the front feed dog should be greater
than that of the rear feed dog. The front feed dog, therefore,
feeds an amount of fabric which the rear feed dog can take
up behind the needle without stretching the fabric. (E)
Pucker - free seams in nylon or closely woven
fabrics.
The distance travelled by the rear feed dog should be greater
than that of the front feed dog. The front feed dog, therefore,
holds the fabric back so that the rear feed dog can take it up
behind the needle without any puckering. (F)
Adjusting the differential feed
The differential feed can be adjusted by simply turning the dif-
ferential feed adjustment dial in the direction desired. Always
make a trial run. The differential feed is innitely variable and
can be adjusted while sewing.
Adjusting the differential feed
Simply turn the dial in the direction desired for fully variable
adjustment while sewing. Test sew.
