- Low product scrape
- Very fast time for weight and color changing
- Industry 4.0 technology
- Predictive maintenance operations
- Line control by tablet and smart-phone
Dedicated Storing
and Dosing Units
of polymer and
masterbatch are
needed for the
automatic feeding
of the extruder
with a volumetric
or gravimetric system.
A suitable mono-screw
Extruder for the melting
of the polymer is heated
by electrical resistors
and it is supplied with
an Exchange Filter for the
removal of eventual
impurities that could
damage the subsequent
process equipment.
The melt is carried
by a Metering Pump
toward the Transfer
Line and then toward
an electrically heated
Meltblown Spinning Beam
containing several
hundred small capillars
for the continuous
filaments extrusion.
The extruded filaments
converge in a stream of
hot air to extremely reduce
the fine diameter fibres
that are attenuated and
subsequently blown onto
the main conveyor belt
for the forming of the
meltblown web.
A cooling calender
reduces the meltblown
thickness.
The electrostatic bars
improve the filtration
efficiency of the material
that it finally wound
up and slit in the SW Winder.

Leonardo 1.0 is quick
The production reaches up to 1.000 meters of fabric per minute. A quicker production without compromising the quality.
Leonardo 1.0 is efficient
Leonardo 1.0 technology allows a fast cleaning and maintenance process to reduce downtimes. This is a big step forward and ensures a high level of productivity. Leonardo 1.0 saves customers’ time and increases their revenues. The production ranges from 200 kg per hour per linear meter of spunbonded fabrics, to 50 kg per hour per linear meter for meltblown fabrics.
Leonardo 1.0 is green
Ramina pays close attention to minimize the impact of its lines on the environment. For this reason the high productivity of Leonardo 1.0 goes hand-in-hand with energy saving technology.
Leonardo 1.0 is versatile
It opens an array of opportunities. Spunbond, meltblown or composite: the choice is yours. Leonardo 1.0 gives you the technology to adapt your production according to the product you need to produce. The line can be fitted with multiple technologies while guaranteeing a stable production process and uniform results.
