Abstract: An apparatus (10) for assembling lamellar packages for electrical use in electric machines such as motors, generators, transformers, meters, ignition coils and similar electrical equipment by means of a bonding with mono- or bi-component glue, arranged outside or inside a shearing mould (30) and comprising means for applying a quantity of glue (33) on a lower surface (32) of a sheet (32) according to a pitch corresponding to the advancement pitch of said sheet (32), said means for applying a quantity of glue comprising means for withdrawing the glue from a container element and means for depositing said glue in simultaneous and synchronous movement with the advancement of the sheet (32) and shearing the laminations by means of a transmission (11).

Abstract: An apparatus (10) for the assembly of lamellar packs for electrical use in electric motor machines, generators, transformers, counters, ignition coils and similar electrical equipment by gluing, comprising a die-cutting station (12) for die-cutting a sheet (15) to define strips (15?) to be superimposed one on the other to define a lamellar pack and a station (14) for gluing—by means of glue—said strips (15?) sheared from said sheet (15) and comprising means for the discrete application of an amount of glue on a surface of the sheet (15) and with said means operating synchronously with the advancement of the sheet (15) in the die-cutting station (12).

Abstract: The laminar article for electrical use comprises a plurality of superposed first metal laminations fixed together. Each of the first laminations is provided with at least one fastener projecting from a first surface thereof and defining a recess in its opposite side. Each fastener of one lamination is arranged to fit into a recess of an adjacent lamination. The article presents second laminations interposed between at least two adjacent first laminations fixed together. The second laminations are provided with through apertures which are traversed by the fasteners 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.

Abstract: A device for constructing a laminated article, in particular for electrical use, having mutually superposed metal laminations provided with elements or clips for connecting the laminations together. The clips project from the surface of the laminations and are formed by deforming the laminations. The laminations include cavities, each arranged to house a clip, whereby the cavities and clips constitute coupling elements of male-female type. The clips are punched from a metal strip in a first station, die-cut and stacked in a second station and coupling cavities are formed in a third station which may be the same as the first station.

Abstract: A laminated article in particular for electrical use including mutually superposed metal laminations provided with elements or clips for connecting the laminations together. The clips project from a surface of the laminations and are formed by deforming the laminations. The laminations include cavities angularly spaced apart from the clips. Each cavity is arranged to receive a respective clip from an adjacent lamination such that the laminations are coupled together via the clips and cavities. The cavities and clips constitute separate coupling elements of male-female type. The cavities are preferably through cavities extending from one planar surface of the lamination to an opposed planar surface.
