MECHANICAL DETAIL
Belt Drive The board is transported on ‘O’ ring type belting which is driven by two moving
coil motors, one on each rail.
The speed of these motors is controlled by a MultiMove card in the machine
controller which can be adjusted via the machine diagnostics (Belt Speed
Calibration page).
NOTE
For belt speed calibration refer to the Calibrations Section of this chapter.
Board Clamps A board clamping arrangement is utilized to minimize board distortion during
print process. A pneumatically operated piston, (via a 24v switched solenoid
16SOL10 from the machine controller), lowers the board clamp and foil trapping
the board on the transport belts. On completion of the print stroke the board is
released by activation of the pneumatic solenoid.

Board Snugger
Assembly
The board snugger assembly is an alternative option to the standard board clamp
arrangement. This feature is utilized when there is a requirement to print close
to the board edge.
The adjustable snugger plate, rear rail guide and fixed snugger plates are
interchangeable with similar units to facilitate differences in board thickness.
This system caters for 0.8mm, 1.0mm and 1.6mm board thickness.
To clamp the board in position for the printing process, the board is gripped
between the fixed and adjustable snugger plates by action of the pneumatically
operated piston (figure below refers). Pneumatic operation utilizes the existing
board clamp circuit, (via a 24v switched solenoid 16SOL10 from the machine
controller).
On completion of the print stroke the pneumatic solenoid is de-activated allow-
ing the actuator pistons (sprung loaded), to retract the adjustable snugger plate
away from the board.
