1. Description of product
1.1 Description of proper use
The 1220/5 is a sewing unit which can properly be used for sewing
light to medium-weight material. Such material is, as a rule, made of
textile fibres. These materials are used in the garment industry.
In general only dry material must be sewn on this machine. The
material must not contain any hard objects.
The seam is generally made with core thread, polyester fibre
or cotton threads.
The dimensions for needle and hook threads can be taken from the
table in chapter 4.2.
Before using any other threads it is necessary to estimate the
consequential dangers and to take the respective safety measures, if
required.
This sewing unit must only be installed and operated in dry and
well-kept rooms. If the sewing unit is used in other rooms, which are
not dry and well-kept, further measures to be agreed upon may
become necessary (see EN 60204-31 : 1999).
We, as a manufacturer of industrial sewing machines, assume that at
least semi-skilled operating personnel will be working on our products
so that all usual operations and, where applicable, their risks are
presumed to be known.

1.2 Brief description
The Beisler 1220/5 is a single-head sewing unit for serging and
overlocking of long skirt and trousers parts. The overlocking of the seat
and fly bow as well as of the trousers hem can be integrated.
All sewing unit components are mounted on a stand welded of square
steel tubes and controlled by a microprocessor system.
The sewing unit is operated via a control panel. Here it is possible to
call up various control programs, to define new programs and to check
all inlets and outlets for maintenance and repair purposes.

4. Operation of the sewing machine head
4.1 General notes
1
The operation of the sewing machine head (needle insertion, threading
of needle thread and hook thread etc.) is described in the attached
separate Pegasus operating instructions.
The instruction manual is included in the accessories of the sewing
unit.
Attention: Risk of injury!
Please read the operating instructions of the sewing machine head
carefully and observe all notes on safety.
7
4.2 Recommended threads
Needle system: B27
Recommended
needle size: Nm 80 for very thin material
Nm 90 for thin material
Nm 100 for medium-weight material
Nm 110 for heavy-weight material
High sewing security and good sewability are achieved with the
following core threads:
–
Two-ply polyester endless polyester core-spun
(e.g. Epic Poly-Poly, Rasant x, Saba C, ...)
–
Two-ply polyester endless cotton core-spun
(e.g. Frikka, Koban, Rasant, ...)
If these threads are not available, the polyester fibre or cotton threads
listed in the table can also be sewn.
Often two-ply core threads are offered by the thread manufacturers
with the same designation as three-ply polyester fibre threads
(3cyl.-spun).This causes uncertainty with regard to twisting and thread
thickness.
When in doubt, unravel the thread and check whether it is twisted 2- or
3-ply.
The label no. 120 on the thread reel of a core thread corresponds e.g.
to the thread size Nm 80/2 (see table values in brackets).
In case of monofilament threads you can use needle threads and hook
threads of the same thickness. The best results are achieved with soft
and elastic threads (software) of the thread thickness 130 Denier.

5. Operation of the sewing unit
5.1 Feeding the trousers parts and starting the sewing process
The overlock unit 1220/5 works semi-automatically.
The operator of the sewing unit has to do the following:
l call up the desired seam program;
l feed the material precisely;
l supervise the sewing process of the unit;
l remove the finished parts from the stacker.
5 3
4 3 2 1
Feeding the trousers part and starting the sewing process
1) Select the seam program at the control panel (see chapter 6.3).
2) Position the trousers part 1 from the right on the table top 2 and
under the contour guide 3.
ATTENTION!
As soon as the trousers part is pushed under the light barrier 5, the
sewing process starts automatically and the contour guide 3 lowers.
3) The trousers part is sewn.
4) As soon as the workpiece has left the light barrier 5, the seam
is finished and the stamp 4 lowers.
5) The contour guide 3 moves upward.
6) The stacker clamp moves to the front.
7) The stamp 4 moves upward again.
8) The trousers part is stacked with an air blast.
10
5.2 Adjusting the edge guide
4 3 2 1
1
The height-adjustable edge guide ensures a precise positioning of the
trousers part in front of the sewing head. The height of the edge guide
can be adjusted according to the thickness of the material to be sewn.
The draw roll 3 guarantees that the workpiece is precisely guided
under the sewing foot.
Adjusting the height of the edge guide
–
Draw dial 1 in the direction of arrow.
–
Set dial 1 on one of the four lock-in positions.
Position 1 = minimum height
Position 4 = maximum height
Fine adjustment of the height of the edge guide
–
Turn dial 2 correspondingly.
Setting the contact pressure of roller 4
–
Turn dial 3 in clockwise direction
The contact pressure of the roller is increased
–
Turn dial 3 counter-clockwise
The contact pressure of the roller is reduced

2
The blowing nozzles 1 in the table top support the precise stacking of
the workpieces.
–
Set the intensity of the air blast by dial 2 at the control panel.
Turn the dial to the right = increased intensity of air blast
Turn the dial to the left = reduced intensity of air blast
12
By means of the guide blade 1 the run of the workpiece can be
influenced.

5. Pneu ma tic con nec ti on
For the operation of the pneumatic components the sewing unit has to
be provided with anhydrous compressed air.
ATTENTION!
For a trouble-free function of the pneumatic control processes the
compressed air net has to be rated as follows:
Even in the moment of maximum air consumption the minimum
operating pressure must not drop below 6 bar.
In case of a too high air pressure decrease:
–
Increase the compressor output.
–
Increase the diameter of the compressed air supply line.
3 2 1
Connecting the compressed air maintenance unit
–
Connect the connecting hose 3 to the compressed air net.
Setting the operating pressure
–
The operating pressure amounts to 6 bar.
It can be read off at the manometer 1.
–
For setting the operating pressure pull up and turn the rotary
handle 2.
- Turn in clockwise direction = increase the pressure
- Turn counter-clockwise = reduce the pressure
2
ATTENTION !
No oil-bearing compressed air must be fed from the compressed air net.
Behind the filter cleaned compressed air is withdrawn as blowing air
for cleaning machine parts and for blowing workpieces out.
Oil particles contained in the blowing air lead to malfunction and
stains on the workpieces.
