Extrusion line for the production of stetched and unstretched net

IRS

 IRS has been designed and engineered for the production of stretched and unstretched net

IRS

The IRS line produces extruded netting in polypropylene, polyethylene, LLDPE or EVA that can be used to pack food products and industrial articles, or for other uses such as water, air and oil filtration. The line modular design allows setting different setups, according to the type of net to be produced. It is possible to obtain UNSTRETCHED tubular or open-flat nets, or other STRETCHED nets wound on spiral-crossed rolls.

The IRS line can be linked to the STC equipment to produce stabilized and bottom sewn sacks.

The line is equipped with:

• Extruder Ø 45 mm with an operating screw with a 1/28D ratio
• Master color batching group
• Bidirectional rotating head on several models
• Screenchanger with manual control
• Motorized stainless steel water cooling tank equipped with a device to maintain constant water level
• Stretching group with tank, cylinders and water dropping and recovery system made of stainless steel or aluminum with pneumatic release of the rubber draw rolls to facilitate the   film threading operation (only for the stretched version)
• Simple contact winder type AS or double contact winder type AD (only for the UNSTRETCHED version)
• Winder with manual change type A20D with 2 winding stations: one working while the other is ready for back up (only for the STRETCHED version)
• Winder with automatic change type AW (only for the STRETCHED version)
• 2 electrical equipments: the first one is analog with screens, standard keyboard and thermoregulators for temperature control, the other one equipped with PLC and digital “touch screen” with the possibility to store different parameters according to the type of nets to produce. This last type includes a remote assistance kit.
• A.C. motors
• Safety devices as per EC regulations.

OPTIONAL:

  • Granule suction group
  • Simple or double cutting device (for UNSTRETCHED net)
  • Interchangeable dies
  • Under head calibrator gauge of different diameters
  • Expansion shafts for winders
  • Water cooling device at closed circuit
  • Pressure detection system before and after the schreenchanger.

Technology

The IRS 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 an expensive variable for all the manufacturers, the IRS line has been engineered with dedicated components that allow recovering the kinetic energy.
