Abstract (en)
[origin: WO2015185852A1] The invention concerns a method and a facility for progressively transforming a strip of metal material (25). Said method comprises the following steps: Providing a progressive die (12) comprising a plurality of workstations (14, 16, 18, 20, 22, 24); providing a longitudinal strip (25) of a metal material having a series of strip portions (48, 50, 52, 54, 56, 58, 60, 62); and driving said strip (25) through said progressive die (12), at a predefined pitch, while actuating said progressive die (12) at each pitch such that said plurality of workstations (14, 16, 18, 20, 22, 24) simultaneously transforms a plurality of strip portions, Providing heat energy to said strip of metal material (25), upstream from at least one of said workstations of said plurality of workstations (14, 16, 18, 20, 22, 24).
