Non-Repeat Device

The upper dead centre of the knife
beam is stopped and controlled
by control switches S52 and S54
and is monitored by the safety
processor control system which
immediately stops the knife travel
in case of any irregularities. Refer
to "Setting the Automatic Stop-
ping Device".
In addition, all PERFECTA
guillotines are provided with a
mechanical non-repeat device
(catch/locking pin), a third safety
means for the upper dead center,
which locks the knife beam to the
machine frame.
