Abstract (en)
A method for die-cutting from a metal strip (11) a succession of semi-finished pieces or blanks (10) which interpenetrate with one another, where said strip (11) is fed to a workstation comprising a die (14), which includes a first punch (17)-matrix (17A) assembly (15) and a second punch (18)-matrix (18A) assembly (16), which are set opposite to one another and move with respect to one another, operating in succession and alternately on said strip (11), which is moved in step-like fashion between them. The relative movement between said strip (11) and said assemblies (15, 16) in the course of die-cutting of a number of successive blanks is such as to ensure a significant saving in terms of material employed. <IMAGE>
