摘要： A method for assembling an amorphous metallic transformer core includes providing at least one coil of amorphous metallic strip, unwinding the amorphous metallic strip from the coil, utilizing a roll feed to transport the amorphous strip along a longitudinal direction through a shearing section, along a bridge plate, and into an accumulator roll, advancing a first end of the amorphous strip into the accumulator roll a predetermined distance, stopping the accumulator roll while the roll feed continues to feed the amorphous strip at a set speed, moving the bridge plate from a closed position to an open position, moving a deflector plate from a non-deflecting position to a deflecting position, continuing to operate the roll feed so that a first desired feed length of the amorphous strip is achieved, and shearing the amorphous strip at the first desired feed length to produce an amorphous strip comprising the desired feed length.

摘要： According to an exemplary embodiment, an apparatus for assembling an amorphous metallic transformer core from a plurality of amorphous metallic strip packets comprises an unwinding section comprising a plurality of uncoilers. Each of the plurality of uncoilers operated to unwind a coil comprising a single-ply continuous strip of a metallic material. A collection tray is configured to transport a composite metallic strip from the unwinding section, the composite metallic strip comprising a plurality of single ply metallic strips that are unwound from the plurality of uncoilers of the unwinding section. A shearing section operably coupled to the collection tray and configured to receive the composite metallic strip from the unwinding section, the shearing section configured to shear the composite metallic strip into a plurality of packets, the shearing section comprising an accumulator for holding the plurality of the packets of the composite metallic strips. A winding section is configured to receive the plurality of the packets of the composite metallic strips from the shearing section, the winding section forming a metallic transformer core from the plurality of packets of the composite metallic strips.
