Sewing head, Fig. 6:
The machine can be equipped with either a narrow or
a wide sewing unit
2
. The seam width is determined
by the width of the pressure foot of the sewing unit and
by the setting of the rule stop
7
.
The standard version of the system comprises the ma-
nually set rule stop
4
to ensure a constant seam
width throuhout the entire length of the sewing piece.
The pneumatically controlled rule guide
8
allows
a tapered seam width by controlling the contour gui-
de advance in the direction of Y using the shaft
6
and the catch
7
.
The photocell
1
at the sewing head controls the
sewing start. When the reflection of the light beam on
the reflective area
3
is interrupted by the cloth ma-
terial, the pressure foot lowers. Depending on the pre-
set start mode, the sewing process now starts fully au-
tomatically or must be started manually.
The curve which the contour guide travels for controlling
the closing seam is calculated by the program control,
unit using the input X/Y values (see Section D, Pro-
gramming Instructions).
NOTE - Reflective film
The reflective area
3
of the photocell must not be
damaged as otherwise a failure of the sewing unit will
occur.
