Packaging: in taped rolls with paper band insertion unit with Mobert patented fold/loop and continuous thermoregulated hot air welding. Nastrosac welding machine with brushless servo-motors with integrated management. N.1 Double motorised single folder.

The line is completed with a new rolling unit with 4 spindles able to guarantee 25 changes per minute at a maximum speed of 350 cycles per minute. Stabilised welding unit with double Ni-Cr plate; welding temperature approx. 30 – 40 °C. Auxiliary soldering for tape reinforcement, with independent temperature control. Closed circuit liquid cooling. Continuous sealing system with film moving at constant speed. Pre-cutting knurling unit with quick adjustment system depending on thickness and type of material incorporated in the sealing unit. Mechanical film blocking system patented by Mobert.

Production data and bag length digitally set on monitor with possibility to store production “recipes”. This allows the type of processing to be changed quickly by recalling the previously stored data set at the touch of a button.
Automatic taping machine to seal the rolls with gummed paper. Conveyor belt for roll extraction. Computerised electronic management of the entire production cycle. General control of the main causes of stoppages with instructions displayed on the control monitor.
