stitch and thread cutting. All other functions, such as
seam curve route or determining the beginning and the
end of the seam, are acquired by the sensor system
and controlled by the program control unit in accordance
with the set values.

head are monitored by sensors (top thread monitor and
bobbin rest thread monitor). The thread holder can hold
two thread bobbins.

tion where it is positioned. The exact position of the main
clamp is measured by the photocells at the reflective
stripe of the stop rail.
