Abstract
A corner protecting device of vacuum molded paper fiber wherein the device is molded onto a porous mold form, the mold form having valleys about twice the width of the material thickness when molded causing the material at the two sides of the valleys to merge and form columnar-like lands connected by rebounding arch-shaped material thus producing a complex resistance to crushing. Splitting is reduced by undulating tunnel configurations, bottom flanges and a dome shaped peak.
