This marker is designed to straddle
an existing belt conveyor and requires the drive to the marker and
timber to be exacted from the belt. The marker can operate
with a maximum of four roller markers which receive operating signals
issued from the Strength Testing Machine via a central control console
arrangement. Each of the rollers is actuated to the timber
surface by a pneumatic operated cylinder and inking is pressure
fed from separate tanks, allowing different colours
to be used for each roller.
