Adjusting

the

differential

feed

on

the

hobbylock

786

The

differential

feed

prevents

inter-ply

shift.

It

consists

of

two

feed

dogs,

arranged

one

behind

the

other,

which

both

pick

up

and

move

the

workpiece

at

the

same

time.

The

feed

amount

of

either

feed

dog

can

be

set

separately.

It

is

possible

to

have

the

workpiece

moved

more

by

the

front

feed

dog

than

by

the

rear

one

and

vice

versa.

Owing

to

that

very

good

sewing

results

are

accomplished.

Set

the

diffe

rential

feed

according

to

the

material

you

wish

to

process

(see

table

on

page

20).

The

following

settings

at

button

are

possible:

of

front

feed

both

feed

dogs

Setting

dog

Setting

=

Front

feed

dog

set

for

longest

possible

stroke,

rear

feed

dog

possible

stroke

The

differential

feed

can

be

set

infinitely

from

0.5

to

2,

also

during

sewing.

Note:

The

following

variants

can

be

employed

to

obtain

fashionable

effects

on

garments:

The

gather

effect

is

obtained

at

a

diffe

rential

feed

setting

of

1.5—2

when

light

fabrics

are

processed.

The

wave

effect

is

obtained

at

a

diffe

rential

feed

setting

of

0.5

when

medium

to

heavy

elastic

fabrics

are

processed.
