of the Discovery ring, the dosing unit, the EAGLE sensor and
the thermal modulation in a close loop. The whole production
control is summarized by Navigator 9000, a 15 inch touch
screen where the entire process is displayed. The core of the au-
tomation is Navigator 9000, a powerful computer which con-
trols and manages every parameter through a special algorithm
named BATCH TIMING SYSTEM, able to automatically start the
production in only two minutes. A GUINNESS WORLD
RECORD.
GRAMIXO DBK: A continuous gravimetric dosing system with
an extruder control very suitable for bubble film production.
The advantages of the double eye lid and the Vibration Immu-
nity System patented technology are combined with the advan-
tages deriving from the special “batch timing system” algo-
rithm, allowing a very high reading frequency and an une-
qualled precision: 4,000 readings per second.
The Vibration Immunity System, the free weighing hopper and
the digital technology enables an extreme precision even in pre-
sence of high vibrations.
Two weighing cells weigh the material decrease in the mixer
and ensure that the extruder correctly observes the schedule
with a direct relation and control on the haul-off in order to
guarantee the highest precision in the weight/linear metre
ratio.
The system is set for up to eight direct dosing units. A powerful
microprocessor controls the machine with a 10 inch touch view
and makes the operator interface simple for management acti-
vities.
The possibility to extract the mixer for production change ope-
rations is an important and unique Gramixo feature.
Weight/metre control is an essential equipment for a quality
process. Gramixo can be connected to a supervising system
that allows to control, collect and store data from several
plants.
GRAVICO DLK : The Moretto continuous loss in weight dosing
system from two to eight stations, a multi component gravime-
tric dosing system with an automatic weight/linear metre.

Regulation, fitting all continuous cycle systems for plastics pro-
cessing where a constant component feeding and perfect dos-
ing are required. This operation is independent from the mate-
rial specific weight and, moreover, process control is constant.
The system works by continuous weight loss, self-adaptive to
production requests and allowing high savings. Gravico con-
trols the film weight and thickness and adapts the production
to the line speed: a simplified interface and a touch screen con-
trol make the system easy and flexible. The finely balanced
weighing cell, and the advanced electronics allow to manage
also complex situations. The system needs no maintenance ac-
tivities thanks to its simple mechanical concept. The start-up
phase is very fast and allows production starts and changes in
only two minutes. Extreme modularity and production stability
are based on an automatic system and increase productivity
and supply repeatability keeping quality constant.
The construction and the working principle guarantee a perfect
material mixing avoiding materials and additives stratification.
GRAVICO is compatible with MOWIS supervising system.
