ABSTRACT:
Moulded fibre protectors for rectangular edges or corners of articles and having convergent ribbed and grooved walls contacting surfaces of the articles adjacent the edge or corner, the walls being joined by hollow ridges so that the walls of the article converge within channels inside the ridges, or within a convergence of the channels in the case of a corner protector, are improved by arranging the ribbing of the walls so that the hollow ridges adjacent the convergence of the walls are provided with maximum support by internal primary land portions on the protector walls which are uninterrupted by grooves formed on the inner surface of these walls. These primary land portions are divided from remaining land portions by primary grooves extending generally parallel to those edges of the protector walls remote from the convergence.
