Abstract: An assembly for minimizing the springback of wire end portions of electrical wires that are arranged in seats of a ferromagnetic core when they are subjected to twisting, comprising a twisting apparatus which is provided with a fixed body on which a carousel is mounted so that it can rotate. The carousel comprises at least two bushings which are provided with respective channels which are substantially parallel to an axis of symmetry of the carousel, each channel defining at least one receptacle configured to partially accommodate at least one respective wire end portion of a wire that protrudes from a seat of a ferromagnetic core. The at least two bushings are configured to be made rotate in order to perform the twisting of the wire end portions of wires that protrude from the seats of the ferromagnetic core and are partially accommodated in the channels.

Abstract: A method urges a blank along an axial direction between a movable bending tool and a stationary counter-tool and, while the blank is being moved forwards, of moving the bending tool from a neutral position, in which the blank is not bent, to a working position, in which the blank is bent to the desired bending centerline radius, the working position being rotated with respect to the neutral position by a given angle of rotation depending on the desired bending centerline radius. The method further includes urging the blank between a pair of shoes upstream of the bending tool so as to make the deformation of the blank easier, and the step of moving the bending tool from the neutral position to the working position is carried out by controlling at least two degrees of freedom of the movement of the bending tool in the plane defined by the axial direction and by a transverse direction perpendicular to the axial direction.
