B.2.1 Operating principle and machine cycle
Operating principle:
The automatic multi-head serging machine 1365-4 allows the automated
serging of inseams and side seams of trouser panels, with or without knee
lining. The machine can be equipped with up to three sewing heads.
C machine (optional) for serging the waistband, hem, and fly seam,
A machine for serging the inseam or side seam. If the machine has only
B machine for serging the seam opposite the trouser panel worked with
The operating principles of the A machine and of the B machine are identical:
During the sewing process, the contour guide controls the routing of the
seam along the fabric contour. The sewing unit sews and serges the fabric contour automatically and incorporates the fullness for the knee lining,
if required.

the A machine.
Machine cycle, Fig. 2:
The trousers panels are prepared on the two shel-
ves 3:
At the bonding station 5, the front trousers
panel and the knee lining are secured to each
other with a bonding mesh.
Now, the short seams can be serged at the C
machine 4 or at the A machine 6.
Then, the sewing pieces are lined up at the
contour guide of the A machine 6, and the
fully automatic sewing process starts.
The cross transport picks up the sewing pie-
ces at the transport unit of the A machine and
transports them to the B machine 2 where
the second, opposite seam is serged.
The transport unit of the B machine transports
the sewing piece from the working plate to the
stacker 1 where they are stacked on top of each other.
As soon as the sewing process starts at the A machine, the next trou-
sers 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 3 and the lower
stamp 4 press the sewing
pieces together so that they
are secured to each other.

B.2
B.2.3 Guiding of the sewing pieces
The guiding of the sewing pieces along the stop of the A and B machines
is controlled by the combined action of contour guide and puller. When sewing with excessive arc contours, the support is activated for rotating the
sewing pieces.
Contour guide, Fig. 4:
Operating Instructions Automatic Multi-Head Serging Machine 1365-4Beisler 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 unit stop.
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 adjustment of the thickness.
The distance between the contour
guide sliding plate
working plate can be changed 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 adjustment made with the height quick adjustment can be fineadjusted. 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 pass through the gap.
The pressure that the contour roller 6 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.

Control, Fig. 5:
The control of the sewing pieces along the sewing stop 5 is affected
by:
the puller speed 6,
the pressure that the contour roller 4 applies to the sewing pie-
ces.
The photocell 1 uses the reflective film 2 to determine the deviation of the fabric contour 3 from the ideal routing and readjusts the speed
of the puller 6 as required.
If the sewing pieces are shifted 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 4 pushes the sewing material toward the
stop 5 as a result of its orientation. 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 high,
if the sewing pieces warp at the stop, the pressure is too low.
The required contour roller pressure is determined in sewing tests in
combination with the puller speed.

Functions of the machine
In the sewing range of the waist curve, the position of the support
is changed at the B machine to rotate the trousers panel for the sewing
process. If the trousers panel inseam is effected at the B machine, the
puller also swings out at the pivot

to ensure that the trousers
panels are positioned correctly at
the stacker.

B.2.4 Serging the seam
Sewing heads, Fig. 7:
Each sewing head performs the sewing, thread
cutting, and serging functions. The sewing units
of the A and B machine also incorporate the
fullness for the knee lining, as required.
The start of the sewing process is triggered by
the photocell 1 when the sewing pieces
at the stop 3 of the sewing unit are moved toward its sensor range. As soon as the photocell recognizes the sewing pieces (photocell
darkens), the sewing process at the A machine starts:
the trousers panel is sewn,
the knife 4 serges the seam,
the thread rests are aspired into the waste
container.
This sewing process is repeated at the B machine for the opposite seam.

NOTE - Reflective surfaces of the photocells!
The reflective surfaces of the photocells at the A and B machines must not
be damaged or dirty as otherwise the sewing unit control may be impaired.
NOTE - Cancelling the sewing process!
When the program stop switch at the operating panel is depressed, all
machine movements and the sewing process are stopped immediately. The
switch is locked after it has been depressed and must be unlocked for a
reset (machine restart).

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. This is required when waved lining is sewn.
Presetting, Fig. 8:
Functions of the machine
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).

B.2.6 Transport
Transport unit of A machine, Fig. 10:
The transport unit of the A machine consists of
puller 2 and roller 3.
The puller transports the sewing pieces du-
ring the sewing process.
The roller moves the sewing pieces to the
cross transport and also supports the trans-
port function of the puller. This 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 near the A machine. The air
blows from below against the trousers panels; the
resulting air cushion reduces friction during the
transport.
Cross transport, Fig. 11:
The cross transport, consisting of double stamp
1
and accessory stamp 4, picks up the sewing pieces 3 at the A machine and transports
them across the sliding panel 2 to the B machine. If the sewing process at the B machine is not completed, the cross
transport stops at a wait position 5 in front of the B machine.

Transport unit of the B machine, Fig. 13:
The transport unit of the B machine comprises the puller 1 and a
roller 4.
The puller transports the sewing pieces during the sewing process,
the roller moves the sewing pieces from the worktable to the stak-
ker. To ensure that the trousers panels are stacked flush at the
stacker, the roller swings out at the pivot 3 when inseams are
sewn.
The working plate has compressed-air nozzles 2 near the B machine. Just like at the A machine, the transport process is
supported by a compressed
air cushion.

WARNING - Electric shock!
Contact with current-carrying components may cause a lethal electric shock. Check plug and cable before connecting
machine to power supply system.
Do not use damaged plugs, sockets or cables to con-
nect the machine to the power supply system!
The machine is operated with a supply voltage of 230 V
± 10 % at 50/60 Hz. The power supply cable must have
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.

Press the (key
v Top transport
Within a sewing program, the width distribution can be corrected by quick
adjustment of the top transport both at the A machine and at the B machine.
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 frequency for adapting the puller speed is set with the program con-
trol.
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 A machine to the point where the cross
transport picks it up or at the B machine from the worktable to the stacker.

C.5.8 Adjusting the contour guide
The following adjustments are made for the contour guide:
Height quick adjustment:
Fig. 7: Use the handwheel 2 of the four-stage quick adjustment for
the rough adjustment of the material thickness. With each additional
stage, the distance between the sliding plate and the working plate
increases by a fixed value of 0.8 mm. The selected stage is indicated at
the hand-wheel.
Stage 1 0.8 mm
Stage 2 1.6 mm
Stage 3 2.4 mm
Stage 4 3.2 mm
Height fine adjustment:
The adjustment made with the height quick adjustment 1 can be fineadjusted using the height fine adjustment 2. The following should be
observed as a rule: The sliding plate 4 should lower as fas as possible, the fabric must pass easily below the sliding plate.
1. Slide the sewing material below the sliding plate.
2. Push the sliding plate manually
down all the way to the stop.
3. To lower the sliding plate even further, rotate the handwheel
counterclockwise.
4. Pull fabric below sliding plate to
check whether the sewing material
can pass easily.

Contour roller pressure:
The pressure that the contour roller
6
applies is crucial for the conti-
nuous guiding of the sewing pieces
along the sewing unit stop. The required pressure is determined by trial and
error.
1. Line up sewing piece and start machine cycle. If the sewing pieces
are shifted sideways away from the
stop 7, the pressure is too low;
rotate adjusting screw 3 counterclockwise to increase the pressure.
2. If the sewing pieces warp at the stop, the pressure is too high; rotate
adjusting screw 3 clockwise to reduce the pressure.
3. The pressure of the blowing unit 5 should remain unchanged.

C.5.15 Setting the pressures
Fig. 14: To improve the gliding characteristics of the sewing pie-
ces, the working plate has six compressed-air nozzles near the A
and B machines. The air blows from below against the sewing
pieces; the resulting air cushion reduces friction during transport.
The pressure depends on the weight of the material used.
The pressure that the rollers of the two transport units apply to
the working plate can be matched to fit the thickness of the material used.
The required air pressure that can be set with separate valves
must be determined by trial and error. To change the pressure:
1. Pull the valve knob out to unlock the valve, then set the pressure by rotating the valve.
2. To lock the valve, push the valve knob in.

5. Rotate the pressure pad back onto the guide and
cut the bonding strip at the edge 2 of the guide.
NOTE - Position of the lower stamp!
The proper function of the bonding unit
is only ensured if the lower stamp is in
the lowered position. By actuating the
switch 5, the lower stamp can be moved to the upper or lower position.
For cleaning, the lower stamp is moved
to the upper position, and the bonding

Setting the speed of the motion sequence:
1. To change the speed of the forward motion, rotate the
ajusting screw of throttle 6.
2. To change the speed of the rearward motion, rotate
the adjusting screw of throttle 8.
3. Directions of rotation:
Rotate throttle counterclockwise to increase the
speed.
Rotate throttle clockwise to reduce the speed.
Coordination of the motion sequence:
If the roller valve switches early, the linkage strikes. The
distance between the start cam and the roller valve contact 5 must be increased.
If the roller valve switches late, the motion sequence is interrupted. The distance between the start cam and the
roller valve contactor must be reduced.
The positioning of the cams must ensure that the closing
cam switches the motion of a linkage off when the start
cam of the subsequent linkage has actuated the contact
at the roller valve. The motion sequence of the stacker
consists of six steps:
1. Cylinder 1 picks up.
2. Roller valve 12 is activated.
Cylinder 2 lifts.
3. Roller valve 32 is activated.
Cylinder 3 throws over.
4. Roller valve 11 is activated.

2.1 Program control layout
The program control is controlled using three different kinds of menus:
1. Operational menus with direct acces
2. Programming menus
3. Service menus
Operational menus
The operational menus are used to directly select functions that
allow corrections of the sewing process,
support auxiliary processes required during machine operation, e.g.
allow the enabling or disabling of machine functions, e.g. differential
Programming menus
The programming menus are used for programming sewing programs
and pertaining seams:
modifying existing seams,
copying and renaming sewing programs,
programming new seams,
erasing seams.

passing thread through needles,
transport or top transport.
Service menus
The service menus are used for managing sewing programs; they offer
functions that support the set-up and the testing of the machine:
transmission and storage of data,
input/output tests for the initiators of the compressed air system,
diagnostic tests for motors,
additional programs.
Access to some of the service menus and programming menus requires an access privilege that protects the data from unauthorized manipulation. In the service menu, data can only be input or changed after
the service code has been entered. If required, the service code can be
requested from the machine manufacturer.
Menu level structure
The operational menus consist of direct access 1 and direct access 2.
The programming menus consist of level 1 and level 2.
The service menus range from level 2 to level 5.
CAUTION - Machine damage!
Some of the menu inputs will start individual machine
components or a machine run. If components have been
partially or completely removed or are not operational,
machine components may be damaged.
Do not input data unless the machine is operational!

Program control
D.2
Sewing program
A sewing program controls the entire machine operation during production:
transport of the sewing piece to the sewing head,
sewing of a seam,
the transfer of the sewing piece to the B machine sewing head,
the stacking of the sewing piece.
A sewing program is determined by three different kinds of values:
Sewing functions
Sewing functions are machine components that can be enabled or
disabled to perform part of a sewing process, e.g. roller or
stacker.
Sewing parameters
Sewing parameters are settings that refer only to one particular
seam of the sewing program. Changes to the sewing parameters will
affect only the currently selected seam of the sewing program for
which the setting is made.
Basic parameters
Basic parameters are values that control the basic functions of the
machine. Changes to basic parameters will result in changes of all
stored sewing programs.
Sewing programs can be extended, renamed or copied.
In a sewing program, at least one seam must be activated. If a sewing
program consists of several seams, a subset of seams may be deactivated.
Basically, it is possible to create entirely new sewing programs; however, it is easier to:
copy a factory-programmed sewing program to a free location in the
memory and to modify this program,
copy an already modified sewing program to a free location in the
memory and to adapt it further in accordance with the intended purpose.
Seam number
Each sewing program can be executed with up to seven seams. The
seams are assigned to the sewing program by seam numbers (1, 2, 3,
4, 5, 6, 7).
NOTE - Editing seams!
Any data changes in the program control, such as
setting parameters,
changing seam names,
copying seams,
erasing seams,
always apply to the marked seam of the sewing program
shown on the display.

Memory
Sewing programs are stored in the memory (M).
The program control memory can contain up to 20 sewing programs
(M 01-M 20).
All sewing programs stored in the memory can be copied and stored to
the memory card for data backup.
Factory settings
The program control has three factory-installed sewing programs.
M 01-M 03 for standard fabric materials.
M 09 Sewing program for manual post-sewing.
The mamory locations M07-M08 are freely programmable.
M 10-M 20 are reserved for modified or freely programmable se-

Functions of special parameters:
v Top transport
w Differential transport
To ensure the correct width distribution, the transport characteristics of
differential transport and top transport must be fit to match the material
of the knee lining. This is required when waved lining is sewn.
For this purpose, the quick adjustment can be used to change the orientation of the differential transport unit or of the top transport unit to
the sewing unit in a value range of -19 to +19. This setting affects
only the section of the seam for which fullness has been activated.
Fig. 5: Splitting the seam into sections:
Within the sewing range, the trousers panel splits into five sections:
Side seam A with basic setting
S1 - S4 = 15 cm, S5 is the remaining trousers length.
Inseam B with basic setting S5 -
S2 = 10 cm, S1 is the remaining
trousers length from photocell 15.
The knee lining C extends 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.
Fig. 5
Changing the fullness by accessing the complete parameter list of the
sewing function.
Basic setting:
When this menu is opened, the input field 3 of the basic
setting parameter is activated (i.e. it appears on a black

3.2 Programming menus
You can use the programming menus for programming sewing programs and the pertaining seams.
Basically, it is possible to create entirely new sewing programs; however, it is easier to:
copy a factory-programmed sewing program to a free location in the
memory and to modify this program in accordance with the production requirements,
copy an already modified sewing program to a free location in the
memory and to modify it further in accordance with the intended purpose.
For creating a new sewing program, the following working steps are required:
1. Occupy free memory.
2. Add new seams or copy existing seams into a sewing program.
3. Configure seams (as required by production).
NOTE - Backward scrolling in program levels!
When the programming menus are selected, the menu
used last is always displayed. This level is indicated by
the number (1) placed in front of the functions. For selecting certain functions, you may have to scroll backward in
the programming and service menus.
Select the programming menus:
Press the ( key
Scroll backward in programming menus:
Press the + key
Occupying free memory
Sewing programs are stored in the memory (M).
The program control memory can contain up to 20 sewing programs
(M 01-M 20). At the factory, sewing programs are programmed to memory locations M 01, M 02 and M 03.
1. Request free memory location:
Taste ) drücken
2. Enter two-digit numeric description using the numeric keypad.

Copying a seam into a sewing program
Existing seams can be copied into the sewing program and then be modified in accordance with the specific application. This procedure is
usually easier and quicker as the copied seam already contains sewing
functions and parameters required for the new seam. The programming
always refers to the currently selected sewing program.
1. Select programming menus:
2. Select the INITIAL PARAMETER function:
Programming Instructions Automatic Multi-Head Serging Machine 1365-4Beisler GmbH
Programming
Press the ( key
Press the e key
Programming level 2 is displayed.
3. Select the COPY FROM SEAM NO. function:
Press the c key
4. Enter the number of the seam to be copied into the input field.
5. Confirm copy process:
Press the % key
6. The display shows * O.K. PLEASE WAIT* to indicate that the copy
process has been successfully completed.
Then, the seam number is shown in the display field of the sewing
program.
Modifying a sewing program seam
The sewing parameters that were changed as a result of the copy process can now be fit to match the production process. The sewing parameters of a sewing programs can be changed separately for the A and
B machines in three stages:
1. Quick change of the major parameters for a sewing function by
using the input fields.
2. Access to the complete parameter list of a sewing function.
3. Enabling or disabling of a sewing function or machine function.
