Pfaff Hobbylock 784 User Manual

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:

Setting

dog
set

possible
stroke,
rear

The
differential
feed
can
be
set
infinitely
from
0.5
to
2,
also
during
sewing.

The
following
variants
can

fabrics
are
processed.

wave
effect
is
obtained

rential
