It is a flexible automatic system starting from strip for the production of side panels for metal containers with punching-notching solution, marking with lateral profiling with point welding to unite edges, manipulator with press for the execution of trapezoids. Such solution allows a quick change of width (PMD roll forming line with mobile supports), of length (from CNC) and of the n° of trapezoids (from CNC). It is characterized by productivity 3 pcs/min with panels with 5 trapezoids. As options it could be added a cutting press with stacker before the roll forming line for flat cut pieces.
