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.
