Abstract (en)
[origin: EP0116749A2] An interior core protector (20) for protecting the interior (12) of a coil of material (10), e.g., coiled sheet steel, from damage is disclosed. The core protector (20) includes a pair of overlapping formed angular paperboard members (22, 24) each having a series of spaced die cuts (26) in one leg (22b, 24b) thereof permitting the angular members to be bent to conform to the inner diameter of the coil (10). The cuts (26) in one leg (22b) are offset from the cuts in the other leg (24b) such that when the protector (20) is bent for placement in the interior core (12) of the coil (10) and the width of the cuts (26) increases, a paperboard segment of one member (24b) nevertheless overlies the cut (26) in the other (22b) to provide protection for the material about the full circumference of the interior core (12).
