IDRA

Safety and optimization

An air-jet system at the exit point of the milling box for the continuous movement of fabric allows – when needed – users to avoid bag-sewing the fabric ensuring the total absence of creases. Furthermore, thanks to the independent control of the pressure in the milling box and the auto-measuring system of the fabric, it is possible to monitor the shrinkage percentage in real time and automatically stop the machine when the desired percentage level has been reached, with the sewing point automatically positioned in front of the operator, in order to reduce unloading times to a minimum. Each squeezing cylinder is, in itself, an electrical motor that is controlled by an inverter. The forced air introduced by the cold temperature inside the cylinders allows the motor to withstand the temperatures that increase during the milling process, while both in gear and at a standstill.

Independent Motorised Cylinders

The Idra motorization system is innovative and PATENTED. Each squeezing cylinder is, in itself, an electrical motor that is controlled by an inverter. The independent milling cylinders, covered with a layer of grooved synthetic rubber, contain grids that guide the fabric inside the milling box, making sure that lighter fabrics don't get trapped in the crevices that divide the cylinder from the hinge.

Programming and remote maintenance

The IDRA is completely managed through the PLC and interfaced with a touchscreen display, simple and immediate. The programming of the pressure levels and the lightening of the upper cylinder, as well as the independent regulation of the adapter pressure of each individual milling box, allows for excellent personalisation of treatments and perfect repeatability over time. The use of the Inverter guarantees the highest possible energy efficiency of the motor. An online help system allows for constant monitoring of the working status of the machine and for the immediate identification of any eventual intervention zone.

Anti-slip traction

The milling box is tilted downwards towards a base that is covered with a layer of anti-friction material to aid the flow of the fabric. Additionally, the traction functions more smoothly thanks to both the independent nature of each cylinder and the inverter that modifies the individually applied power for each channel, thus avoiding micro slippages that are typical of the more traditional machines.

Flexibility and ease of maintenance

It is possible to set specific milling cycles for every type of fabric loaded, allowing the user to obtain a superior qualitative result in respect to traditional milling machines: within the same colour range it is possible to carry out, for each of the four channels, independent processes in terms of composition, length and weight of the wool, while autonomously managing the milling percentage and cycles. The systems also allows for maintenance intervention in individual channels, ensuring production continuity in the others.
