ABSTRACT:
A pallet has at least one board secured to a plurality of like elongated parallel stiffening ribs having flat upper sides secured to the board and lower sides formed with downwardly projecting and longitudinally spaced bumps. These ribs are each formed by filling into an upwardly open elongated mold of generally regular cross section a mass of coarse and fine particles and a binder in such a manner that the fine particles are concentrated in the lower portion of the mass and the coarse particles are concentrated in the upper portion of the mass. The mass is then compressed downwardly in the mold to a relatively great extent at several longitudinally spaced-apart locations and to a lesser extent therebetween to form upwardly projecting bumps or feet between these locations. The thus compressed mass is cured into a stiffening rib which is inverted and has the board secured to its planar upper surface opposite its feet.
