ABSTRACT:
A metal strip wound up in a coil on a feed spool is split by supporting the feed spool for rotation about a horizontal axis and passing the strip along a generally horizontal feed plane through a rotary-blade cutter and subdividing the strip at the cutter into a plurality of even substrips and a plurality of odd substrips interleaved with the even substrips. The even substrips are guided upward in an upper plane forming a small acute angle with the feed plane from the cutter to a respective even-strip windup spool and these even substrips are wound up on the even-strip windup spool. The odd substrips are guided downward in a lower plane forming a small acute angle with the feed plane from the cutter to a respective odd-strip windup spool and these odd substrips are wound up on the odd-strip windup spool. The cutter and the feed spool are rotated at substantially the same speed and both the windup spools are driven at a speed slightly greater than the speed of the cutter and feed spool to pull the substrips from the cutter and the strip from the feed spool. The positions of the spools are adjusted to maintain the planes in substantially the same orientation relative to one another.
