Automatic determination of the average thickness of each piece and constant maintenance during all the production. The system is connected to the speed control of the extruder rotation and to the speed control of the pull off. The GENIUS control is able to manage up to 3 Co-extrusions. The pull off controls and the Co-extruders controls, are all grouped in the same panel, while the speed synchronization of screw’s rotation and the pull off will facilitate the speed up and the start up, reducing the timing and the waste parts. The resistant structure built in stainless steel (INOX AISI 304) brings support to the extrusion hopper or to the hopper loader. If any of the extrusions is fed by more materials, the dosing system can be mounted directly onto the extrusion machine.
