Abstract
A tool is described which is particularly adapted for detaching by peeling sheet metal strip from a wound construct containing a plurality of coiled strips interconnected by intermittently spaced tabs that bridge the parting lines between adjacent strips. The tool is effective to fracture the tabs without distorting or marring the adjacent strip material.

A method of fracturing tabs for detaching strip from a wound construct of sheet metal web material in which adjacent strips are interconnected by frangible tabs intermittently spaced along the parting line between the facing edges of adjacent strips, comprising the steps of:
- (a) rotating said construct in the strip-uncoil direction;
- and
- (b) diverting out of the plane of the construct the edge of the object strip opposite the edge containing the tabs to be broken to impose on said strip internal stresses to be resisted at each successive tab by a reactive force of sufficient magnitude to fracture said tab.
In combination with a wound construct of sheet metal web material having a plurality of laterally spaced, longitudinally extending parting lines defining a plurality of laterally spaced coiled strips, said strips being interconnected in side-by-side relation by intermittently spaced tabs bridging the parting line between adjacent strips, means for detaching a strip from said construct by fracturing said interconnecting tabs sequentially along the length of an affected parting line, said means comprising:
- (a) means for rotating said construct in the strip-unwind direction;
- and
- (b) means for diverting the edge of the object strip opposite that containing said interconnecting tabs along a path of travel outwardly of that traversed by said interconnecting tabs.
