A. System constitution
The unwinding machine developed in this research is
shown in Fig. 3 and this machine is used to unwind the fine
gold wire from the spool for the winding machine
as shown
in Fig. 4. The system A winds the fine gold wire to the win-
ing spool independently and the system B unwinds the gold
wire from the unwinding spool. The tension of the fme gold
wire during the unwinding and winding processes should be
kept constantly to avoid or reduce the wire disconnection.
