B.2.1 Operating principle and machine cycle
Operating principle:
The automatic single-head serging machine 1265-4 allows the automated
serging of inseams and side seams of trousers panels, with or without knee
lining. The sewing unit automatically sews and serges cleans the fabric contour and incorporates the fullness for the knee lining, if required.
The trousers panels are sewn in separate machine cycles:
the inseam or side seam of the rear trousers panel,
the inseam or side seam of the front trousers panel with knee lining on
the inseam or side seam of the front trousers panel with knee lining on
Operating Instructions Automatic Single-Head Serging Machine 1265-4Beisler GmbH
Functions of the machine
top,
bottom.
NOTE - Applications
The machine has been designed predominantly for serging
trousers panels. However, it can also be used for processing
other sewing pieces, e.g. sleeves, short trousers, etc.
Machine cycle, Fig. 2:
The short seams can be serged manually at the sewing head 2 prior to
the sewing of the inseam or side seam.
The trousers panels are stocked on the upper tray
5
, the knee linings are stocked on the lower tray
4
. The trousers panel is placed onto the working
plate, the corresponding knee lining is aligned to
the trousers panel with the hems being flush.
At the optional bonding station 6, the front and
rear trousers panels can be secured to each other
using a bonding mesh.
Both trousers panels are routed below the con-
tour guide 3 and lined up at the stop of the sewing head 2. A photocell starts the sewing process. The fully automatic machine cycle is started.
During the sewing process, the contour guide 3 and the puller of the
transport unit 7 control the routing of the seam.
If required, the top and bottom transport units of the sewing unit incor-
porate fullness.
The transport unit 7 transports the sewing piece from the working plate
to the stacker 8 where the sewing pieces are stacked on top of each
other.
As soon as the sewing process starts at the sewing head 2, the next
trousers panels can be secured at the bonding station.

B.2.2 Securing the sewing pieces
Bonding station, Fig. 3:
To prevent the trousers panel and the knee lining from being shifted during the sewing process, they are secured to each other by hot pressing at a lateral location.
At the bonding station 1, a
bonding mesh strip 3 is placed between knee lining and
trousers panel and heated by
the lower stamp 4 of the
press unit.
Then, the upper stamp
and the lower stamp
press the sewing pieces together so that they are secured to each other.

B.2.3 Guiding of the sewing pieces
The guiding of the sewing pieces along the stop of the sewing head is controlled by the combined action of contour guide and puller.
Contour guide, Fig. 4:
Operating Instructions Automatic Single-Head Serging Machine 1265-4Beisler GmbH
Functions of the machine
During the transport of trousers panel and knee lining to the sewing unit,
the contour guide controls the shape of the fabric contour and ensures
the exact routing of the seam along
the sewing stop 6 of the sewing
unit.
At the contour guide, the following
settings are made for the thickness
of the fabric:
Height quick adjustment 1 of
the contour guide:
Use this control for the rough ad-
justment of the thickness.
The distance between the con-
tour guide sliding shield 4 and
the working plate can be chan-
ged in four stages of 0.8 mm
each in both directions.
Stage 1: smallest distance
(0,8 mm)
Stage 4: largest distance (3.2
mm)
Height fine adjustment 2 of the contour guide:
The rough adjustment made with the height quick adjustment can
be fine-adjusted. The following should be observed as a rule:
A single fabric layer should pass easily below the sliding plate
while a double layer must not be allowed to pass through the gap.
The pressure that the contour roller 7 applies to the sewing pie-
ces is set with the adjustment screw 3.
The setting of the compressed-air nozzle 5 that blows the sewing pieces against the stop should not be changed to adjust the contour control.

Fig. 4
Stop:
The standard version of the machine has a stop that is secured to the contour
guide.
Optionally, the machine can be equipped with a pneumatic stop.
With this option, a pocket pouch can be inserted between trousers panel
and lining and serged. In this case, the seam section to the end of the pouch
is sewn manually, the remaining section of the seam is sewn fully automatically.
The section that is sewn manually is determined by parameter 10 of the
sewing function STATION CLOSE. At the end of this section, the transport
unit is lowered, the pneumatic stop moves to the pressure foot, and the contour guide controls the seam.
B-6
Operating Instructions Automatic Single-Head Serging Machine 1265-4 Beisler GmbH
Functions of the machine
B.2
Control, Fig. 5:
The control of the sewing pieces
along the sewing stop is affected by:
the puller speed 4,
the pressure that the contour
roller 3 applies to the se-
wing pieces.
The photocell 1 determines
the deviation of the fabric contour 2 from the ideal routing at
the reflective film and readjusts
the speed of the puller 4 as required.
If the sewing pieces are shif-
ted sideways away from the
stop, the puller speed is too
high,
if the sewing pieces warp at
the stop, the puller speed is
too low.
The frequency for adapting the puller speed is set with the program control.
In addition, the contour roller 3, due to its orientation, pushes the sewing
material toward the stop. The lateral thrust depends on the pressure that
the contour roller applies to the sewing pieces:
If the sewing pieces are shifted sideways away from the stop, the
pressure is too low,
if the sewing pieces warp at the stop, the pressure is too high.
The required contour roller pressure is determined in sewing tests in
combination with the puller speed.

B.2.4 Serging the seam
Sewing head, Fig. 6:
The reflective surface 3 of the photocell must not be damaged or dirty
as otherwise the sewing unit control may be impaired.
Operating Instructions Automatic Single-Head Serging Machine 1265-4Beisler GmbH
Functions of the machine
The sewing head performs the sewing, thread cutting, and serging functions.
As soon as the photocell 2 recognizes the sewing
pieces 1 (the reflective surface 3 of the photocell is concealed by the sewing piece), the sewing
process starts:
the trousers panel is sewn,
the knife 5 serges the seam,
the thread and fabric residues are aspired into
the waste container.
NOTE - Reflective surfaces

B.2.5 Width distribution for knee lining
To ensure the correct width distribution, the transport characteristics of differential transport and top transport must be matched to fit the material of
the knee lining.
Presetting, Fig. 7:
In the sewing range of side seam A
and inseam B, the trousers panel
splits into five sections with the knee
lining C extending over four of these sections. For each section, the
length can be varied and the pertaining fullness (quantity) can be preset
with the program control (see Section D, Programming Instructions).
Quick adjustment, Fig. 8:
The operating panel allows direct
access for the quick adjustment of
the fullness by modifying top transport 2 and differential transport 1.
Select the corresponding function and modify
it in a range between -19 and +19 (see Section D, Programming Instructions).

B.2.6 Transport
Transport unit, Fig. 9:
Operating Instructions Automatic Single-Head Serging Machine 1265-4Beisler GmbH
Functions of the machine
The transport unit consists of puller 2 and
roller 5.
The puller transports the sewing pieces
during the sewing process and uses its
rotational speed to support the control of
the fabric contour.
The roller 5 moves the sewing pieces
beyond the worktable edge and also supports the transport function of the puller.
This additional transport function can be
enabled for heavy fabrics.
To improve the gliding characteristics of the
trousers panels, the working plate has six compressed-air nozzles 1 in the sewing head
area. The air blows from below against the
trousers panels; the resulting air cushion reduces friction during the transport.

In the sewing range of the side seam hip curve, the position of the strut
3
is altered to rotate the trousers panel for the sewing process.
B.2.7 Stacking
Stacker, Fig. 10:
As soon as the chain has been severed and the roller has transported
the sewing pieces beyond the worktable edge, the automatic stacker
is activated and deposits the sewing piece 2 over the bundle
rod 1.

Preseams:
Hem seams, fly seams, and hem seams can be serged separately.
The characteristics of the preseams are set in a separate parameters list. These settings are used only if the sewing program for preseams is activated.
Inseams and side seams:
Inseams and side seams can either be serged in individual, separate sewing processes or effected as a combined sewing process with alternating seams.
In this case, the corresponding preprogrammed seams are enabled in quick
access at the operating panel.
Creating identical stitch images:
If identical stitch images are required for inseams and side seams, the knee
lining must always be lined up in the same position (always top or always
bottom). In this case, the trousers panel is lined up alternatingly flush with
the waistband and flush with the hem.

a minimal cross section of 1,5 mm.
Before connecting the machine to the power supply sy-
stem, check to see if the ratings of the power supply
system in the operating room correspond with the ratings on the nameplate at the rear of the machine.
If the ratings for voltage (V) and maximum current (A)
do not match, the machine must not be connected.
Insert the grounding plug into a properly grounded and
fused power socket.
Make sure that the power supply cable is not subjected
to tensile or pressure forces.
2. Switch the machine on by moving the main switch to position I. After
the machine has been switched on, its control program is powered up.
The display shows the most recently selected sewing program.
3. Switch the heating module on. Wait until the red indicator goes off to
indicate that the lower stamp has reached its operating
temperature.
4. Fig. 15: Connect the machine to the compressed air
supply system by installing the compressed air hose
connector to the outlet of the compressed air supply system in the operating room. A pressure reducer 1 reduces the compressed air to the operating pressure of
6 bar. Check the manometer 2 to see if the correct
operating pressure has been set. The pressure reducer
is located at the machine frame.
5. Insert needle, pass top thread through needle and install
bottom thread spool to sewing head (see operating instructions of sewing head manufacturer or supplier).
NOTE - Passing thread through needle
The program control supports the passing of the thread through the needle on both machines.

B.3.5 Modifying sewing program functions
The following functions of a sewing program can either be modified or completely enabled or disabled as executable machine function within a value range:
v Top transport Increase/reduce value
w Differential transport Increase/reduce value
# Puller Parameter 14, speed
x Roller Parameter 30, roller distance
. Sewing speed Speed / waist curve slow
Fig. 17: Enabled functions 1 are displayed as inverted sym-
bols. A disabled function 3 appears as an icon on a bright
background. The parameter value assigned to a function is displayed in the corresponding input field 2 to the right of the
function symbol.
The parameters assigned to the functions are either the additional increase or the reduction of basic values or the direct
modification of the main parameters of a seam.

until the symbol assigned to the input field appears on a black background.
Press the & or / key.
Press the ( key.
v Top transport
Within a sewing program, the width distribution can be corrected by quick
adjustment of the top transport.
To achieve this, the position of the top transport unit to the main transport
unit can be changed within a value range of -19 to +19. This setting affects
only that section of the seam for which fullness has been enabled.
w Differential transport
The position of the differential transport unit to the main transport unit of
the sewing unit can also be changed by quick adjustment within a value
range of -19 to +19. This setting affects only that section of the seam for
which fullness has been enabled.
# Puller speed
The photocell determines the deviation of the fabric contour from the ideal
routing and readjusts the puller speed, as required.
If the sewing pieces are shifted sideways away from the stop, the pul-
ler speed is too high,
if the sewing pieces warp at the stop, the puller speed is too low.
The basic speed of the puller can be changed by using the input field.
x Roller
The parameter changes the length of the distance along which the roller
transports the sewing piece from the sewing head on the worktable to the
stacker.
