Printing decks
The F4 FLEXOEfficiency® utilizes 8 printing decks adapted for front-side or surface printing. The design has been modified for easy maintenance access and daily operational needs through the FLEXOEfficiency® concept. The grids can be moved aside without difficulty, remaining inside the machine.
Doctor Blade
The doctor blade is assembled in a closed swinging chamber mounted
on linear guides, with horizontal movement across a fine manual
adjustment against the anilox. The system has been specially designed
to maintain the inking position with the minimum blade pressure
against the anilox.
The disassembly of the system is easily achieved without any need
to disconnect the inking lines, greatly simplifying all cleaning
and changing tasks.
Platform
The F4 FLEXOEfficiency® is equipped with an overhead platform
that allows access to all elements requiring maintenance, with
the purpose of simplifying parts replacement, maintenance and cleaning
in areas such as the central drum, refrigeration and drying systems
maintenance, and many others.
The press can be configured with an optional automatic drum cleaning
system.
Changing
sleeves
Changing anilox and plate cylinder sleeves take a matter of minutes. The clamps are opened manually, simply and quickly.
Drying
Drying equipment is comprised of two circuits that, with hot air
blown at high speed, evaporate the solvent or water content of
the ink (other types of viscous inks such as EB or UV can also
use this type off equipment with appropriate modifications).
The first circuit is used for drying between printing groups. The
screen lip can be withdrawn from the side of the machine and the
casing includes an inspection port, two important additions resulting
in convenient and simple maintenance.
The second circuit corresponds to the 4m-long drying tunnel, coated with a thick
insulating material to reduce heat loss and made of twelve drying screens each
with a blower lip. The screens can be easily disassembled for cleaning without
tools. Also, a specific access point has been design to allow rapid threading
of the machine.
