Abstract
Abstract A pallet of moldable material, such as high density polyethylene, is ideally suited for transporting yarn packages having tubular cores. The pallet includes top and bottom surfaces with a repeating pattern of nubs upstanding from the top surface and a repeating pattern of depressions in the bottom surface, the depression pattern tracking the nub pattern. The nubs are shaped and dimensioned to receive one end of the yarn package tube thereover, and flexed to provide maximum surface contact with the inside of the tube. The outer surface of the tube also is received within a recess in the top surface surrounding the nub. A number of yarn packages are assembled on a pallet, and an identical pallet is disposed on top of the yarn packages, the depressions in the bottom surface of the top pallet receiving ends of the yarn package cores. The top and bottom pallets cooperate with the yarn package cores to ensure a stable handling unit with very little lateral shifting of yarn packages, and any number of layers may be provided.
