  • Patent number: 4899433
    Abstract: The method and apparatus for pickup of packets with a varying number of stamped laminations, for instance for stators of electrical machines, from a lamination stack (98) compressed under tension between clamping plates (24, 100) is so performed that the first packet half of laminations are always rotated by 180.degree. before the entire lamination packet is measured off and picked up. Therefore, two different stops (42, 44) are needed for measuring off the first half and then the entire lamination packet for each packet height. In order to dispense with the necessity of having to exchange, when changing the packet height, the one clamping plate which heretofore was designed with various stops, the lamination packets with a differing number of laminations are always mounted between the same clamping plates (24, 100) and supported together with the one clamping plate (24) on axially adjustable stops (42, 44). Consequently, the device features axially adjustable stop (42, 44).
