发明名称 Interlocking roll support and spacing structure
摘要 A roll support and spacing member has parallel, connected and nestable first and second sections foldable upon a hinge to provide support structure in the middle of a stack of rolls. The roll support and spacing member has upwardly and downwardly facing, roll-engaging indentations with the sections being separable to provide top and bottom support pieces for engaging rolls in the stack. The sections are movable into superposed relationship with one another. The first and second sections have peripheral flanges located along opposed sides and opposed ends thereof and formed with cooperable interlocking structure positively retaining the sections together when the sections are placed in superposed relationship.
