of the photocell

. When the fabric interrupts the
light beam at the reflective surface, the automatic
machine cycle is started automatically. The seam is sewn and serged.
NOTE - Starting the sewing process
To ensure the correct routing of the seam, the trousers pa-
nels must be released as soon as the transport unit of the se-
wing head has seized the sewing pieces.
NOTE - Resetting the insertion process
Before the response delay period of the photocell has elapsed,
the insertion process can be cancelled by moving the trou-
sers panels out of the sensor range of the photocell.
After the sewing process has started, the machine cycle can
only be cancelled by pressing the program stop switch or by
pressing the function key F1.
Creating identical stitch images:
If identical stitch images are required for inseams and side seams, the knee
lining must always be lined up in the same position (always top or always
bottom). In this case, the trousers panel is lined up alternatingly flush with
the waistband and flush with the hem.
At the waistband side, the sewing process is started by photocell 13 at
the sewing head.
At the hem side, the sewing process is started by photocell 15 which
is integral to the tray. The length of the sewing distance from the be-
ginning to the end of the knee lining is determined by the setting in the
program control.
