ABSTRACT:
This method is practiced by first providing a plurality of spools of amorphous steel strip in each of which the strip is wound in single-layer thickness. Then, in a pre-spooling machine, the single-layer thickness strips are unwound from said plurality of spools and combined to form strip of multiple-layer thickness which is wound to form strip of multiple-layer thickness which is wound onto a plurality of master reels, on each of which the strip is wound in multiple-layer thickness. These master reels are then placed on a plurality of payoffs, and the multiple-layer thickness strip is unwound from these payoffs and combined into a composite strip that has a thickness in strip layers equal to the sum of the strip layers in the combined multiple-layer thickness strips. Then the composite strip is cut into a plurality of sections, or lengths, of composite strip, and with these sections a hollow core form is constructed, which form has a window about which the sections are wrapped.
