ABSTRACT:
Apparatus is disclosed for scroll slitting metal webs into a serpentine wave shaped form having identically shaped sections spaced apart by a common center-to-center distance. The scroll slitting apparatus includes multiple sets of mating scroll slitting knives mounted upon rotatable arbors for slitting the metal webs into multiple strips having serpentine wave-shaped edge sections. The apparatus also includes a recoiler and a looping pit positioned between the scroll slitting knives and the recoiler. The looping pit permits slack to be placed in the strips between the stripping station and the rewind station such that the strips may all be spaced apart a distance slightly greater than the amplitude of the serpentine wave shaped edge placed on the strips, thereby enabling all the strips to be rewound onto a common arbor or shaft.
