Board Clamps A board clamping arrangement is utilized to secure the board during the print
process and to minimize board distortion. 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.
An in-line pneumatic exhaust ensures quick release of the board clamps.
