Abstract
This method of making packets of amorphous metal strip adapted to be wrapped about the arbor of a transformer-core-making machine comprises providing first and second composite strips, each comprising many thin layers of amorphous metal strip stacked in superposed relationship. The composite strips have leading ends that are located in initial positions (i) axially spaced from each other at the start of a packet-making operation and (ii) at opposite ends of a stacking zone where the packets are built up during a packet-making operation. The composite strips are cut to detach first sections of strip from the first composite strip and to detach second sections of strip from the second composite strip; and the detached sections are axially advanced forwardly of the respective composite strips from which they are detached into said stacking zone. The second sections are stacked in alternating relationship upon the first sections in the stacking zone.
