B.2 Functions of the machine
B.2.1 Operating principle and machine cycle
Operating principle:
The automatic single-head serging machine 12 5-4 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 con-
tour 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
top,
 the inseam or side seam of the front trousers panel with knee lining on
bottom.
NOTE - Applications
The machine has been esigne pre ominantly for serging
trousers panels. However, it can also be use 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 se-
wing head 2. A photocell starts the sewing pro-
cess. The fully automatic machine cycle is star-
ted.
 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 Functions of the machine
B.2.2 Securing the sewing pieces
Bonding station, Fig. 3:
To prevent the trousers panel and the knee lining from being shifted du-
ring the sewing process, they are secured to each other by hot pres-
sing at a lateral location.
At the bonding station 1, a
bonding mesh strip 3 is pla-
ced 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 to-
gether so that they are secu-
red to each other.

B.2 Functions of the machine
B.2.3 uiding of the sewing pieces
The guiding of the sewing pieces along the stop of the sewing head is con-
trolled by the combined action of contour guide and puller.
Contour gui e, Fig. 4:
During the transport of trousers pa-
nel and knee lining to the sewing unit,
the contour guide controls the sha-
pe 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 4
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 pie-
ces against the stop should not be changed to adjust the contour control.
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 automa-
tically.
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 con-
tour guide controls the seam.

B.2 Functions of the machine
Control, Fig. 5:
The control of the sewing pieces
along the sewing stop is affec-
ted 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 con-
tour 2 from the ideal routing at
the reflective film and readjusts
the speed of the puller 4 as re-
quired.
 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 con-
trol.
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 Functions of the machine
B.2.4 Serging the seam
Sewing head, Fig. 6:
The sewing head performs the sewing, thread cut-
ting, and serging functions.
As soon as the photocell 2 recognizes the sewing
pieces 1 (the reflective surface 3 of the photo-
cell 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
The reflective surface 3 of the photocell 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 Functions of the machine
B.2.5 Width distribution for knee lining
To ensure the correct width distribution, the transport characteristics of dif-
ferential 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 the-
se sections. For each section, the
length can be varied and the pertai-
ning fullness (quantity) can be preset
with the program control (see Sec-
tion D, Programming Instructions).
Quick a justment, 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 Sec-
tion D, Programming Instructions).

B.2 Functions of the machine
B.2.6 Transport
Transport unit, Fig. 9:
The transport unit consists of puller 2 and
roller 5.
 The puller transports the sewing pieces 4
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 sup-
ports 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 com-
pressed-air nozzles 1 in the sewing head
area. The air blows from below against the
trousers panels; the resulting air cushion re-
duces 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 se-
wing piece 2 over the bundle
rod 1.
