1. Description of product
1.1 Description of proper use
The 1280/5 is an engineered sewing station 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 1280/5 is an engineered sewing station for closing long
seams, as e.g.
® trousers side seams and crotch seams,
® side seams without vent in upper fabric,
® lining in skirt parts
According to the machine head it is possible to sew
® double-chainstitch seams (401),
® 4-thread safety seams (515) or 5-thread safety seams (516).
The engineered sewing station is mainly used for sportswear trousers,
as e.g. cotton trousers, Chinos and US style trousers.
All sewing station components are mounted on a stand welded of
square steel tubes and controlled by a microprocessor system.
The sewing station 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
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.

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 engineered sewing station
5.1 Feeding the workpieces and starting the sewing process
The engineered sewing station 1280/5 works semi-automatically at
high speed.
The operator of the sewing station has to do the following:
® call up the desired seam program;
® feed the workpiece precisely;
® start the sewing process by foot switch;
® supervise the sewing process of the unit;
® remove the finished parts from the stacker.
1
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) Place the trousers parts on the preparation table and align them.
3) Hold the trousers part to be processed with the left hand.
4) Seize the trousers parts to be processed with the right hand in such
a way that the middle finger is under the lower trousers part, the
forefinger between both parts and the thumb on the upper trousers
part.
5) Hold the trousers parts in front of the feeding aid in such a way that
the three guides of the feeding aid can move under (3), between (2)
and above (1) the trousers parts.
6) Actuate the foot switch.
The feeding aid moves forward and closes.
7) Position the trousers parts guided by the feeding aid under the
sewing foot until the feed-dogs seize them safely.
8) Switch the contour guide on again in the hip bow area by stepping
back on the pedal.
9) Release the trousers parts shortly before the end of the sewing
process.
The remaining sewing process is done automatically.
–
The holding stamp is lowered to avoid that the trousers parts slide
away.
–
The finished trousers parts are stacked.
11
5.2 Adjusting the blowing air for the nozzles in the table top
1
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 = increase the intensity of air blast
Turn the dial to the left = reduce the intensity of air blast

The finished workpieces are stacked on the throw-over stacker 2.
The stacked and clamped workpieces can be removed by actuating the
foot switch 1.
The stacker is accessed by a control pulse. The pneumatic functions
can be taken from the pneumatic wiring diagram.
Caution: Risk of injury!
Do not reach into the working area of the throw-over stacker during the
stacking operation.
