| MAIN
FEATURES |
|
|
This machine has been
designed on the basis of the experience
made on its “sister” FA-X Superstar,
described in the previous pages, thus maintaining
the same process concepts and also the most of the
components employed, while the chassis has been
optimized being more compact while
still keeping the necessary capability to host the
most requested product features.
“Easy installation and start-up”
concepts are applied: high integration
of drive, pneumatic piping, vacuum ducting, electrical
equipment and wiring, installed inside modules.
For this reason, this machine is definitely one
of the most efficient and reliable
machines in its market segment.
“Full servo technology”:
each process unit is independently driven as well
as each material feeding and transport system so
that machine set-up and format change operations
are easier and each process step can be quickly
adapted when different materials are used or operating
conditions change.
Mechanical version available upon request. |
|
The machine is equipped with innovative
low-tension unwinders with motorized expanding
spindles (one motor per reel), tension control with
dancers, web accumulation systems and automatic
“cut&splice” systems.
These unwinders minimize the stress
on materials durind splices keeping web force lower
than 10 N, thus allowing for the use of less expensive
materials and, in turn, for the reduction of final
product cost; this system increases machine
efficiency due to the reduced downtimes.
Unwinders are typically located “on-line”
to keep machine compactness and reduce space occupation
on operator side.
The cross-wise position of the product structure
materials is constantly controlled through electronic
web tracking and self-alignment equipment.
Several solutions are available
for the feeding of specific materials like elastic
bands, elasticized ear-tapes, tape tabs, frontal
tape (on-line assembly capability or use of pre-assembled
materials, standard or high diameter reels, etc.). |
|
MODE 10 DIS
(Fameccanica.Data patented technology) for highly
efficient fiberization of any kind of treated or
untreated pulp with low power consumption; double
infeed system with automatic splicing
capability through automatic switch of
the pulp sheets.
Fluff absorbent core delivery systems
with rotary drum forming for contoured,
flat or longitudinally and/or cross-wise profiled
pads.
“Multistream” forming
capability allowing different absorbent core designs
and for effective S.A.P. (Super-Absorbent Polymer)
blend applications.
Suitable for “ultra-thin”
absorbent core formation with high SAP content. |
| |
Fameccanica-design process
units are utilized to guarantee the user-friendliness
and the accuracy of each step of the manufacturing
process.
Then, some ingenious solutions are adopted, such
as the edge shaping unit that has been specifically
designed for a long-life, maintenance-free
operation.
Other typical characteristics are: temperature control
(heating or chilling) systems, fine adjustment systems,
push-button operated re-phasing systems (to guarantee
accurate phasing with line in run), integrated lubrication
systems. |

DRIVE
TRAIN AND MOTION CONTROL |
|
|
|
| Brushless servomotors
and digital drivers are employed
and accurately networked to make each process unit
run synchronized at any time. |
| |
LOGIC
CONTROL OF MACHINE FUNCTIONS |
|
|
|
Machine Functional Control
is supplied by a powerful PLC with distributed
I/O allowing the easiest implementation
of retrofitting modules.
Programmable Limit Switch for an
accurate management of electronic phasing (glue
application, etc.).
Operator interface for centralized
management of all machine operation phases (start-up,
shut-down, changeover).
Alpha numerical display of operation
messages on machine running mode, downtime and automatically
rejected products. |
|
Automatic reject control
system with sensors for detection of material
presence and/or application application control
and automatic rejection of defective products, to
guarantee top-quality production
targets.
Visual web inspection system available. |
| |
PRODUCTION
DATA SUPERVISION |
|
|
|
New Fameccanica DATAMATE
system is available and integrated in the
converter operator panel, for the collection, storage
and analysis of production data (production, scraps
and downtime).
Additional functions for specific requirements are
available with Fameccanica Datamate “Plus”:
an advanced version allowing also for the monitoring
of raw material consumption and for multi-shift
statistical analysis. |
|
| A wide range of specific equipment
can be installed for the filtration of the air needed
for the manufacturing process (self cleaning rotary
filters, dry sacs systems, equipment for connection
to centralized plant filtering systems, etc.). |
|
Designed in compliance with European
Safety Regulations.
The whole machine has been designed keeping in mind
operators' safety. Continuous improvements are accomplished
thanks to dedicated internal audits. Safety guards
with safety switches and security locks on operator
and drive side are installed. |
