Abstract

A method and system (100) for production of a sheet metal strip (1) with notched edge (2) is disclosed. The system (100) comprises: a mother reel (D1) from which sheet metal (10) is unwound; perforation means (M) that cross the sheet metal (10) transversally to form a plurality of holes (20) distributed along the sheet metal (10); and cutting means (T) to make a longitudinal cut of the perforated sheet metal in the longitudinal lines passing through the centers of the holes (20) and longitudinal lines in intermediate position with respect to the centers of the holes (20) in such a way to obtain a plurality of sheet metal strips (1) with notched edge (2).
