摘要： The laminar article (1) for electrical use comprises a plurality of superposed first metal laminations (2) fixed together. Each of the first laminations (2) is provided with at least one fastener (3, 3a, 3b) projecting from a first surface (4) thereof and defining a recess (5, 5b) in its opposite side. Each fastener (3, 3a, 3b) of one lamination (2) is arranged to fit into a recess (5, 5b) of an adjacent lamination. The article presents second laminations (9) interposed between at least two adjacent first laminations (2) fixed together. The second laminations (9) are provided with through apertures (10) which are traversed by the fasteners (3, 3a, 3b) which fix the adjacent first laminations together. The method consists of die-cutting a plurality of laminations from a metal sheet, rotating the die-cut laminations and superposing them, to then fix them together in predetermined manner. The laminations can be die-cut with a reference axis thereof rotated through a predetermined angle about a reference axis of the metal sheet, to limit the rotations to be imposed on the laminations during their mutual fixing.

摘要： A sheet metal blanking die assembly, comprising a lower part, an upper part and guide columns. The die assembly upper part and lower part present flat parallel mutually opposing horizontal portions. The lower flat portion is arranged to receive the sheet metal, the upper flat portion presenting a plurality of punches. On the flat lower portion, blanking recesses are present to receive the respective punches and at least one detachment die, below which a brake is present, said brake presenting a through cavity positioned coaxial to that of the detachment die. The brake presents a plurality of contact zones arranged to brake the fall of the individual laminations and possibly to enable the formation of a lamination pack. Means are provided to cool and/or to lubricate just the contact zones between the laminations or the lamination pack and the brake.
