Extrusion line for the production of unstretched net 2 or3 threds

IRB

IRB has been designed and engineered for the production of unstretched nets at 2 or 3 threads.

IRB

The IRB line produces UNSTRETCHED extruded nets at 2 or 3 threads of polypropylene, polyethylene, LLDPE, EVA and PBT to pack food and industrial products or for other uses such as water, air, oil filtration systems.
The line has a modular design and can be manufactured in different versions, according to the type and to the quantity of the net to be produced.

The line is equipped with:

• Extruder with operating screw having ratio 1/30 D
• Master batching group
• Bidirectional rotating head in different models
• Screenchanger with manual control
• Motorized stainless steels water cooling tank, with system of water constant level
• Mechanical water dropping device to dry the net
• Simple unwinder type AS or double type AD
• 2 electric equipments: the first one is analog with screens, standard keyboard and thermoregulators for the temperature control, the other one equipped with PLC and “Touch screen” monitor having the possibility to store different parameters according to the type of nets to be produced
• Main a.c. motors
• Safety devices as per EC rules

OPTIONAL:
• Granule suction group
• Screenchanger at hydraulic control
• Simple or double cutting device
• Interchangeable dies
• Calibrator gauges under head of different diameters
• Expansion shafts for winders
• Fan for forced water exhausting
• CHILLER

Technology

The IRB line is fully equipped with Siemens components and it is entirely controlled by a state-of-the-art HMI based on Profinet®, one of the most advanced communication protocols, that allows controlling each of the installed stations/tools independently and in real time.

FIBORSIN is always focused on its customers’ needs and, as energy costs are expensive variables for all the manufacturers, the IRS line has been engineered with dedicated components that allow recovering the kinetic energy.
