3 Installation
and
putting into service
3.1 Unpacking the machine
Strobel machines are supplied either
as
complete
units
with
head, stand and
motor,
or
head
with
motor
only,
or
the
head only.
Due
to
the
high
weight
and
to
avoid damages during
transport,
complete
units
are packed in several smaller cartons.
Machine
head and
motor
are removed
from
the
stand. Reel stand, rods, oil
and
other
accessories are packed
into
the
stand
packing.
Make
sure
that
all
accessories have been unpacked before
throwing
away
any
packing
material.
3.2 Installation
ATTENTION!
Danger
of
bodily injuries or
finger
bruises
through
pulling
in
of
garments
or
hairs!
The machine
may
not
be operated
without
belt
guards
for
head and
motor.
Caution:
Screw
oil drain pipe
133.0764
to
the
lid
112.0085
before
setting
the
top
part
on
the
table
top.
(See
point
5.1 Oil drain pipe)
When
using
the
3-fold
reel stand
294.0049
the
distance
between
thread
guide arm and cup arm should be approx. 41 em. Using
the
6-fold
reel
stand
394.0049
(optional extra)
the
distance
between
the
thread guide arm
and
the
cup arm
set
to
each
other
at
a
right
angle should be approx.
41
em
and
33
em respectively.
If
the
frame
is
not
delivered
by
us
as
well,
but
rather
the
machine
set
on a
different
frame,
then
the
table
top
needs
to
be prepared as can be seen in
the
table-top
diagram.
ATTENTION!
Bevore
putting
the
machine
into
service make sure
that
the
electrical
connecting
data on
the
motor's
name plate,
your
electric
network,
and all
other
connecting
values,
e.
g.
for
the
air, correspond
to
the
data
shown
on
the
machine
and
the
operating
instructions.

Tensioning the V-belt
C a u t i o n ! Danger of injury!
When
checking
the
belt
tension,
switch
off
the
machine
at
the
mains. Do
not
operate
the
machine
without
the
belt guard.
Otherwise
there
is a D A N G E R
of
crushing fingers,
of
injuries
to
the
body
and
of
pulling in
parts
of
clothing.
The
tensioning
of
the
V-belt
is carried
out
by
swivelling
the
motor
underneath
the
table plate
after
releasing
the
retaining
nut
with
SW
24.
The
V-belt
must
not
be tensioned
too
much,
especially
with
the
stop
motor.
You should be able
to
depress
it
with
light
thumb
pressure
by
about
2 em.
Too
little
V-belt
tensioning can impair
the
positioning
of
the
machine and
therefore
impair
the
function
sequence.

and
threads
4.1.1
(see
chart,
point
2.4
Technical data)
The needle size
to
be used depends on
the
material
to
be
sewn
and on
the
thread respectively. Needle
type
to
be used is 1
35-35.
When
joining fused parts
it
may
happen
that
the
needle eye conglutinates,
which
may
affect
the
loop
formation.
Thicker
and harder material requires
thicker
needles.
Working instructions
Class
141-23
is used
for
attaching
the
insole
to
the
upper, up
to
a
total
thickness
of
7
mm.

1.1.1 Working with gathering device
By class
141-23
the
insole is
sewn
to
the
upper. The gathering device
facilitates
the
distribution
of
extra fullness
of
the
upper
at
the
toe
on
Vulcano
and
light
weight
leather shoes. A
flat
seam is obtained
which
is
completely
covered
when
vulkanizing
the
shoe in a press subsequently.
The gathering device (EV) is operated
by
means
of
the
left
treadle. By
pushing
it
forwards
the
lever
with
guide
186.0195
(fig. 8 and
fig.
10)
of
the
gathering device is
swivelled
between
the
feed cups
by
means
of
the
rod and
the
deflection
lever. By heeling
the
treadle,
the
gathering device
returns
to
its
initial position.
Lift
feed cups
by
means
of
knee lever before
swivelling
the
gathering device.
By using
the
gathering device a
unform
distribution
of
excess material
is
obtained. The operator actuates
the
gathering device on certain
spots
market
at
insole and upper.
After
acquiring
some
experience, such marks
are
not
necessary
any
more. (fig. 9).
Machines used
with
gathering device should be equipped
with
a
stop
motor
for
two
needle positions,
to
simplify
handling and
to
increase
output.
First
position
Second
position

position
The
first
needle position is
impotant
when
swivelling
guide
186.0195,
to
keep
the
shoe in a certain position
when
lifting
the
cups;
this
first
position
is also necessary
for
threading.
