ABSTRACT:
An improved roll support and spacing structure for packaging and handling of multi-layer stacks of rolls of web material. The structure is preferably an elongated molded pulp member. Rolls of web material fit into generally semi-cylindrical indentations in the roll support structure. The generally semi-cylindrical roll cushioning indentations are smooth and free of recesses, and thus substantially eliminate marking, denting and/or scratching associated with such recesses. The smooth, generally semi-cylindrical roll cushioning indentations are crowned to improve strength and reduce sagging during fabrication. Raised lands are located between the roll cushioning indentations. The resulting roll support structure provides the proper combination of strength and flexibility to appropriately cushion the rolls. The formed roll support structure also includes chamfered portions between the smooth crowned roll cushioning indentations and adjacent sidewalls to substantially eliminate markings associated with sidewall rigidity. Preferably, the roll support structure includes two substantially similar elongated members disposed in parallel across a longitudinal hinge. The longitudinal hinge preferably includes elongated formed openings located exclusively between selected aligned lands to facilitate bending and/or tearing along the hinge line.
