Paperboard/corrugated board pallets and methods for manufacturing such pallets

摘要

A paperboard pallet having generally U-shaped, parallel runners with notches along the distal edges of their legs for receiving stringers. The runner legs diverge from the central web and are formed by a plurality of nested paperboard laminations, each having a central web and distal legs. The central webs are defined by spaced parallel scores spaced progressively more closely toward the interior. The stringers each comprise a multi-layered coil of paperboard sheet wound into a tube of triangular cross-section. The sides of the triangle are defined by scores to form fold lines, the scores of the more interior layers being more closely spaced than the scores of the more exterior layers. After scoring, the sheet is wound and bonded. A generally U-shaped saddle cap has a central web which extends between the opposite distal edges of the runner legs and has opposite legs which are bonded to the legs of the runner. A plurality of notches along the distal edges of the saddle caps have a width substantially equal to the width of the stringers and are spaced to register with the stringers.
