Abstract
Disclosed herein is a roll edge protector for packages of laminar material. The roll edge protector is preferably made of plastic, extruded in the shape of a channel and each section of the channel is cut to form two angular sections of edge protectors, each having scallops that are preferably identical to the other. The angular sections can be formed in indefinite lengths and stored or shipped in coils to be uncoiled and applied to the rolls of sheet material.
