The NEVE is a high performances central impression printing
press designed using modern CAD stations and entirely produced
with NC machines tool in the Bonardi factory. The NEVE represents
the "father" of an entire family of high quality
flexo presses with a large number of standard features.
The NEVE family includes 6 & 8 colours presses with
various central drum diameters, in order to generate a maximum
flexo repeat of 800, 1000, or 1200 mm.
Although surrounded by attractive Italian-style guards,
the machine is very operator friendly and job change-over
and servicing is very easily and quick achieved. Four electric
synchronised hoists are provided to enable two operators
to work simultaneously on either side of the machine. There
is a retractable ladder to reach the overhead platform to
facilitate web thread-in and servicing.
The machine can be supplied with driven idler rollers in
the case of low gauge and/or temperature sensitive webs.
The jiant printing section in the version with central
drum diameter of 2300 mm and max. repeat of 1000 mm. There
are two motors for each deck for fast in/out racking according
to the present repeat length. This one gives a precise distance
from the impression setting. Very fine tunning is achieved
by the use of preloaded ball bearing screws with micrometric
reductions. There is hydraulic locking at two preset pressure
levels. Quick changeover of printing cylinders and anilox
rollers is achieved without the use of tools, due to swing-out
housing. The Bull gear is manufactured with a cast iron
core and has an external steel forged toothed ring. The
double walled central impression drum is chrome plated and
ground to a mirror-like finish and the T.I.R. is better
than 8 microns.
