ABSTRACT:
A shipping pallet is constructed of multiple laminations of corrugated sheet material, with specific construction details providing advantages in strength and trueness of the completed pallet, and further advantages in the reduction of tooling and labor costs. The stringers or runners, deck boards, and top and bottom sheets may be sawn from stacks of plural laminations, thus precluding any requirement for costly dies and intensive labor. Asymmetrical corrugated sheets may be used, with one side having a different weight than the other. By laminating two such sheets together with like weighted sides in contact, the tendency of such sheets to curve or warp due to the difference in side thickness is substantially eliminated. Different orientations of the corrugations or flutes of the sheets during lamination and assembly of the pallet, provide advantages in strength for specific applications. The deck boards and stringers may be notched so as to interlock with one another, thus providing additional strength and durability. The pallet may be constructed of plural laminations of various corrugated sheet materials, such as paperboard or fiberboard, or plastic.
