ABSTRACT:
A structure for protectively supporting and spacing rolls of web material in a multi-layer stack. The structure includes an elongated member of expandable polystyrene material having a pair of opposed surfaces. A first of the surfaces has a plurality of spaced parallel generally semi-cylindrical indentations disposed to receive rolls of web material. The radius of each of the semi-cylindrical indentations being greater than the depth of the indentation so that the rolls will be snugly retained within indentations in a pair of members and the members will be out of contact with each other. The member has a plurality of cavities located on the lateral edge surfaces thereof extending transversely of the axis of the semi-cylindrical indentation to render the expanded foam material substantially uniformly thick throughout to enhance uniform curing thereof. The cavities extend only partially through the member and in the region located between adjacent recesses, and each of said cavities have side walls which extend parallel to the contour of the outer extremity of the member. Wall segments are provided in the indentations only along one lateral edge of the member.
