Abstract
Abstract A member for protectively supporting and spacing a plurality of rolls of web material such as cellophane in a multi-layer stack is formed as an elongated bar. The bar has a plurality of spaced indentations along at least one elongated surface for receiving the rolls of the stack. The bar is formed with sufficient flexibility to permit a limited, relative movement among the rolls of the stack. This provides a high degree of protection to the rolls. At the same time, the bar has sufficient strength to prevent crushing of the stack. The bar may be formed of expanded polystyrene foam and, preferably, is formed to embrace the ends of the rolls for protective purposes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A structure for protectively supporting and spacing rolls of web material in a multi-layer stack, comprising an elongated bar of expanded foam material having a pair of opposed surfaces, a first of said surfaces having a plurality of spaced parallel generally semi-cylindrical indentations disposed to receive rolls of web material, the radius of each of said semi-cylindrical indentations being greater than the depth of said indentation, whereby the rolls will be snuggly retained within indentations in a pair of said bars and the bars will be out of contact with each other, said bar having a plurality of recesses located in the side portions of said indentations to provide a greater flexural cushioning by said bars when clamped to said rolls.
Claim 2
Dependent Claim
