Differental

feed

The

differential

feed

consists

of

two

feed

dogs,

one

behind

the

other,

that

assure

that

the

fabric

is

fed

completely

evenly.

It

prevents

the

displacement

of

the

two

fabric

lays.

The

two

feed

dogs

can

be

set

separately

i.e.

so

that

the

front

dog

feeds

more

than

the

rear

dog

or

vice

versa.

This

is

particularly

important

when

sewing

rib

knit.

The

differ

ential

feed

is

set

differently

depending

on

the

type

of

fabric.
