Abstract
Procedure for die-cutting sheets making up magnetic nuclei.From a continuous sheet band (1), for example, rolled in the form of a bobbin, it is die-cut thus defining two lengthwise alignments of modules (2-2') participating in each module there are two sheets with a "U" configuration (4-4'), opposite each other and connected by the end of their side sections, and inside there is another sheet (4''), which also has a "U" configuration, rotated 90 degrees with respect to the former, and inside the latter there is a sheet with a "T" configuration (5) that determines, with the former, two rectangular waste elements (6) these two lengthwise alignments are complemented by modules (2-2') with dual "T"-shaped sheet lengthwise alignment (5'), where the middle section of each sheet is inserted and connected with the middle sections of the other two adjacent and opposite "T"-shaped sheets (5'), with full utilisation of the material in this area, So that in each step of the continuous band (1), six "U"-shaped sheets and six "T"-shaped sheets are obtained with material waste generated in the die-cutting of approximately a third of current waste.
