PROCEDIMENTO ED INSTALLAZIONE PER LA TRASFORMAZIONE DELLA SEZIONE DI UN NASTRO IN PARTICOLARE DI RAME

摘要

This invention concerns a process for transforming the cross-section of a band with parts or reduced thickness without removal of material characterized in that a relative drawing movement of the band in relation to the tool is created over each transverse zone (Zi) in the drawing direction (F) of the band (10), a sucession of elemental compressions is carried out of which each concerns only a fraction of the width of the part the thickness of which is to be reduced, the part of reduced thickness is progressively widened by compressing the adjacent part once again to the initial thickness.
