to sides.
The class identification (type) is located on the right hand side of the machine stand;
the serial and model number (after the dash) are stamped into the base plate's front
surface on the back as well as on the type sign on the back side of the machine stand.
2.3 Intended use of the machine
For automatic roll padding of right and left lapels, completely mirrored and not
warped.
The Strobel roll padder consists of a left and a right machine. Both machines operate
independently from each other.
The longest possible stitch length at the lapel roll line is 58 cm, the shortest stitch at
the lapel tip is about 3 cm.
The shape of the lapel can be user-defined. The edges are scanned automatically by
light barriers.
The edge distance at stitch start (10 mm – 25 mm) and at the stitch end
(10 mm – 50 mm) can be freely set.
The distance between the seams can also be freely set up to about 16 mm.

3Installation and commissioning
The S0 main switch is located on the distribution box below the tabletop (Fig. 1). The
stop button S5 is located in the control box over the tabletop (Fig. 10).
CAUTION! Danger of injury!
The machine's carriage run extends beyond the outer edge of the
machine during operation. Make sure that this area is not accessible,
because otherwise there is a risk of injury.
The machine may not be operated without protective panels (belt
protection) for the upper part and for the motor (beneath the table
top). Otherwise there is a risk of fingers being caught, bodily injuries
and clothing being drawn in.
ATTENTION!
Don´t use as a handle!
Proceed as follows for installation: unpack and clean machine.

11 BA_KA-ED_A22_190313_en.doc
3.1 Lubrication (Fig. 2)
ATTENTION!
The machine must be oiled before first start. The maintenance
instructions according to the operating instructions must be
followed!
On the machine head all the points marked red.The lids (1) and (2) need to be screwed
off for this.
Fig. 2
3.2 Transit support
Remove carriage lock. Unscrew an angle bracket each at the bottom side of the
carriage.
3.3 Direction of rotation of the machine
Right machine half:
The correct rotation of the handwheel is counter-clockwise (left run) when
looking at it.
Left machine half:
The correct rotation of the handwheel is clockwise (right run) when looking at
it.Motor drive by tooth-belts

12 BA_KA-ED_A22_190313_en.doc
3.4 Motor drive by tooth-belts
3.4.1 Tension of the tooth-belt (Fig. 3)
CAUTION! Danger of injury!
Before testing the tooth-belt tension it is essential to switch off the
machine by the main switch S0 and to disconnect the power plug.
The machine may not be operated without belt protection for the
motor.
The tooth-belt should not be tensioned too tight. You should be able to compress it
easily with your thumb by about 5 mm.
Too little or to great tooth-belt tension can be bad for the machine's positioning and
thus impair the function sequence.
Tension the tooth-belt (Fig. 3):
-Loosen the upper and lower fastening screws (1), (2) on the machine upper part.
-Pull motor out a little and slightly tighten the lower fastening screw (2).
-Tension the tooth-belt by swivelling the motor.
-Tighten the upper and lower fastening screws (1), (2) again.
Fig. 3

13 BA_KA-ED_A22_190313_en.doc
3.4.2 Checking the tooth-belt for the carriage drive
CAUTION! Danger of injury!
To check the tooth-belt, switch off the machine electrically and pull
out the power plug.
The machine may not be operated without front panels and back
wall.
Checking the tooth-belt tension (Fig. 4):
-Switch off power switch S0 and pull the power plug.
-Unscrew front panel and rear wall from the frame.
-The tooth-belt (1) should not be tensioned too tight. You should be able to
compress it easily with your thumb by about 5 mm. If the belt is too loose or too
tight, the function sequence is impaired. If the belt is too tight,
it will wear too quickly. In either case the machine will operate slower. The
carriage may bend if the tooth-belt is too tight.
In case the belt tension is not OK, tension the belt properly.
-Loosen central fastening of the drive
unit Hexagonal screw M16x80 (2)
Hexagonal nut M16 (3)
-Loosen the fastening screw (4)
-The drive unit can now be swivelled around the central fastening. Tighten the
belt and retighten the fastening screw. Retighten the central fastening.
-Screw front panel and rear wall to the frame.
-Plug in power plug and switch on main switch S0.

Fig. 4
3.4.3 Positions of the machine
CAUTION! Danger of injury!
Danger of injury by clothing or hair being drawn in as well as danger
of fingers being caught, and needle piercing!
When checking positions while the machine is turned on, keep
fingers and hands away from moving parts.
The machine needs a needle position and a reference position.
Reference position (Fig. 5):
The reference position needs to be set so that the needle's point is aligned with
the inner edge of the needle glide washers in the stitch-in direction.

15 BA_KA-ED_A22_190313_en.doc
Fig. 5
Cutting position: (Fig. 6):
After the looper has taken up the loop, the looper needs to be moved so far so that
the thread of the loop on the needle side hangs on the cloth retainer and the other
side slides in the groove of the cloth retainer. This way the loop half to be cut is placed
on the cutter and is cut across the blade when the carriage retracts.
Fig. 6
This can be simulated by stopping the machine in the stitch with button 1 of the
operating control V810 and activating the solenoid 1V1 by hand. Now the coupling has
to be switched off by toggle switch S6 (Fig. 10) and the carriage pushed back by hand a
little.

16 BA_KA-ED_A22_190313_en.doc
3.5 Pneumatic connection
Each half of the machine is separately connected pneumatically by an 8/6-PA hose to a
connector plug. The maintenance unit is set to 5 to 6 bar operational pressure.
Minimum operational pressure 5 bar.
3.6 Power supply
CAUTION! Danger of injury!
Work on the electrical equipment may be done only by electricians or
properly trained technicians. The exists the risk of fatal electrical
shock.
The electrical connection is separate for each machine half.
ATTENTION!
Before connecting the machine electrically be sure that the local
network voltage and the net frequency corresponds to the machine.
Network voltage and network frequency can be found on the type
sign on the back side of the machine stand.
If network voltage and frequency are not compatible, the electrical
installation of the machine will be destroyed.
3.7 Check light barriers
-Mirror (1) (S8-1) and (2) (S8-2) along the entire length and check for damages.
(Fig. 12a)
-Push carriage manually to the middle.
-Switch on main switch S0.
-Press the START button S4 (carriage moves to basic position).
-Press START button S4 again (clamping device closes).
-Switch toggle switch S6 to “ ” position (“0” position) (carriage can be moved
freely by hand) (Fig. 10).
-Keep an eye on the LED of the light barriers S8-1 and S10 and push the carriage
through slowly by hand. The LED’s should bit lit without interruption along the
entire length; otherwise re-adjust
(see point “5.2 Setting the light barriers (Fig. 16a + Fig. 17)”).
Machine is ready for sewing.
