ABSTRACT:
A corrugated cardboard tube includes a tubular laminar structure of single-lined corrugated cardboard which includes a plurality of strips of single-lined corrugated cardboard spirally wound into a substantially cylindrical configuration to form corresponding single-lined corrugated cardboard layers overlapping and bonded with each other in a radial direction. Each of the strips of single-lined corrugated cardboard is composed of an elongated liner sheet and a corrugated sheet, having a plurality of parallel ridges and furrows, and being spirally turned in a direction perpendicular to the ridges. The corrugated cardboard tube is used as a load bearing member adapted to support a load acting in a direction axially of the corrugated cardboard tube. The corrugated cardboard tube may also be used as leg members of a pallet and, in such case, the corrugated cardboard tubes are bonded at their opposite annular ends to upper and lower tables to complete the pallet.
