This
timing device can be set to give a variable period from half to ten seconds.
During this time the moving block remaings stationary in the open position
before automatically resuming motion at the set dwell period. This is a
particularly useful feature where feeding work requires a fine register
or when large or difficult sheets are being fed which would otherwise have
to be run using the single impression procedure. This device can increase
output to more than double that of a machine on single impression working
and can also be of grdat assistance in the training of operator.
Electromagnetic
clutch and brake enables push - button control of the machine for easy
and efficient operation. Complete safety is ensured by full electrical
interlocking. Electrical synchronization of both the clutch and the brake
eliminates the possibility of time lag or over-lag between driving and
braking. There is a clean penel at operator's easy reach from where all
machine operations can be controlled.
All
moving parts on these machines are protected by approved safety guards.
A special feature is the patented guard whichprotects the operator from
the moving block. Should any object come between the moving blick and
this guard, a slight backward movement of the guard will occur stopping
the moving block immediately and isolating the starting machanism. Until
the Guard is moved forward by hand the machine remains dead and isolated
from any attempt to actuate it through the starting mechanism.
