GENERAL COMPOSITION OF OUR COMPLETE LINES

Extruder:
driven by a d.c. motor, fed by electronic system with controlled diodes. These extruders have an L/D ratio equal to 30 diameters which allows a perfect homogenation of the polymer, even at a high production rate. The extruder is assembled on a special framework which permits both horizontal and vertical movements, in order to obtain a perfect alignment of the extrusion head with the other machinery, as well as to simplify the cleaning of the extrusion complex. The extruder can be moved by means of an electromechanical device.
Continuos flow filter:
with filtering packs which are interchangeable during operation.
Extrusion head:
complete with 90° adaptor, with device for regulating film thickness.
The temperature of the extrusion head and of the adaptor are adjusted and controlled by electronic instruments. A thermocouple assures a constant check of the temperature of the polymer inside the die head.
Temperature control panel:
on which all the thermoregulators which control the temperatures of both the extruder and the extrusion head are located.
Double unwinder:
assembled on a special welded sheets framework, complete with an automatic device for the alignment of the material coated. Changing of the bobbins is done by a rotational movement of the bobbin-holder shafts frame without needing to stop the machine.
Coating group:
complete with a cylinder-type system for transporting, and cooling of the material coated. The cylinders are cooled by a water-circulation system. The machine is equipped with lateral circular blades for cutting of edges, and suction devices for their collection.
Double winder:
assembled on a special welded sheet framework, and driven by two motors which guarantee a constant tension during the winding of the bobbins. Changing of the bobbins is done by rotational movement of the bobbin-holder shafts Frame, without stopping the machine.
The bobbin-holder shafts are of the expansion type in order to obtain a perfect locking of the carton on the spindle.
Treating apparatus:
high tension electrical discharge type.
Feeding and control cabinets:
All the drive motors which are installed in the line are DC with converter or AC with inverter and are fed by a single electronic controlled-diode type feeder, located in a centralized cabinet.
All the operations of the lines are controlled by a single control panel where the indicators and regulating instruments are situated.

Extrusion coating groups suitable for insertion in converting lines for special lamination.
