Drive principle
The wire is driven by 2 electric motors fitted with drive
wheels. The diamond wire is fed around the drive wheels
in the form of a figure eight to ensure optimum grip. The

Saw advance and wire storage
The wire advance operates according to the principle of
a block and tackle working in reverse. The advance move-
ment, causing the wire to be drawn in, is effected by two
compressed air cylinders working in opposing direc-

tions. Accordingly, the rear pulleys (storage pulleys,
280 mm dia.) are mounted on a moving carriage. The
maximum wire storage capacity is 9.2 m. The minimum
length of wire required by the drive system is 3.2 m.
