ABSTRACT:
An interior core protector for protecting the interior of a coil of material, e.g., coiled sheet steel, from damage is disclosed. The core protector includes a pair of overlapping formed angular paperboard members each having a series of spaced die cuts in one leg thereof permitting the angular members to be bent to conform to the inner diameter of the coil. The cuts in one leg are offset from the cuts in the other leg such that when the protector is bent for placement in the interior core of the coil and the width of the cuts increases, a paperboard segment of one member nevertheless overlies the cut in the other to provide protection for the material about the full circumference of the interior core. The core protector is characterized in part by economies of materials used, economic use of such materials, and economies of shipment.
