  • Method of preparing transformer cores without waste
    Patent number: 5671526
    Abstract: Fast and economic process to prepare, without waste, E-I or U-I shaped transformer cores consisting of laminations (1, 2-9,10) that are directly stacked during blanking and are permanently jointed by punched zones (5,5'). Each free end of the E (1) or U (9) shaped laminations has a profile, snap-joint matching the profile (4,4') of the lamination in front of it (2,2) so as to permit their rigid fixing. The laminations are obtained from a steel strip (11) using a discontinuous feed cutting machine from one processing station to the next.
