  • Patent number: 5577608
    Abstract: An improved protective cover for palletized materials and a method for constructing and using the same. The protective cover is formed from two members, each having a substantially "L" shaped cross section comprising two legs or margins which meet at an edge. Material is removed from a portion of one margin of each member forming a notch in that margin. A crease is formed in the opposite margin of each member adjacent the notch. The members are pivotally connected near their ends with connectors. The connected members pivot at the connections and fold at the creases to form a substantially rectangular protective cover to be placed over a palletized stack of materials.

  • Patent number: 4195732
    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.
