Functions of the machine
B.2.3 Guiding 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 guide, 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.
