  • Process for laminating plate packs, in particular transformer cores
    Patent number: 4831718
    Abstract: Positioning of the individual portions is no longer effected on the laminating station but on a positioning station which is arranged upstream of the laminating station. In the positioning station the individual portions of a layer are deposited and positioned by being pushed against each other. The finally positioned individual layer is then delivered as a closed unit to the laminating station and laminated to form a transformer core. The individual portions are stacked on a stacking station in such a way that they are already arranged in the correct relative position with respect to each other.
