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.

We claim: 1. In a roll support and spacing member having parallel, connected, nestable first and second sections foldable upon a hinge to provide support structure in the middle of a stack of rolls and having upwardly and downwardly facing, roll engaging indentations with the sections being selectively separable to provide top and bottom support pieces for engaging rolls in the stack, the sections being movable into superposed relationship with one another, the improvement wherein: the first and second sections have peripheral flanges located along opposed sides and opposed ends thereof and formed with cooperable, interlocking structure selectively engagable for positively retaining the sections together when the sections are placed in superposed relationship, wherein the interlocking structure is formed as a tab and notch arrangement that is selectively engagable and disengagable such that the tab and notch arrangement prevents separation of the first and second sections when engaged, wherein the tab and the notch have winged portions frictionally engagable and in overlapping relationship with one another and are provided on the opposed ends of the sections. 2. In a roll support and spacing member having parallel, connected, nestable first and second sections foldable upon a hinge to provide support structure in the middle of a stack of rolls and having 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 being movable into superposed relationship with one another, the improvement wherein: 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, wherein the interlocking structure is formed as a tab and notch arrangement, wherein the peripheral flanges are formed along their opposed sides with a plurality of engagable bosses for maintaining alignment between the sections when the sections are in superposed relationship. 3. The improvement of claim 2, wherein the bosses are located on opposed sides of the sections. 4. The improvement of claim 3, wherein some of the bosses are round in cross section and other of the bosses are polygonal in cross section. 5. A roll support and spacing member comprising: a first section having a pair of spaced end walls, a pair of spaced side walls, a pair of roll receiving indentations and a peripheral flange extending from the pair of end walls and the pair of side walls; a second section having a pair of spaced end walls, a pair of spaced side walls, a pair of roll receiving indentations and a peripheral flange extending from the pair of end walls and pair of side walls; a tab formed on the peripheral flange of the first section; and a notch formed on the peripheral flange of the second section, wherein when the first and second sections are folded along the hinge into a superposed position, the notch is selectively engagable with the tab to retain the tab for positively retaining the first and second sections in the superposed positions and preventing separation of the first and second sections, wherein the tab and notch each have winged portions to frictionally engage and overlap with each other. 6. A roll support and spacing member comprising: a first section having a pair of spaced end walls, a pair of spaced side walls, a pair of roll receiving indentations and a peripheral flange extending from the pair of end walls and the pair of side walls; a second section having a pair of spaced end walls, a pair of spaced side walls, a pair of roll receiving indentations and a peripheral flange extending from the pair of end walls and pair of side walls, wherein the first and second sections are foldably interconnected along a hinge formed between the peripheral flange of the first section and the peripheral flange of the second section; a tab formed on the peripheral flange of the first section; and a notch formed on the peripheral flange of the second section, wherein when the first and second sections are folded along the hinge into a superposed position, the notch retains the tab for positively retaining the first and second sections in the superposed positions, wherein the peripheral flange of the first section includes a plurality of first bosses and the peripheral flange of the second section includes a plurality of second bosses, wherein the first bosses receive the second bosses when the first and second sections are folded along the hinge and in the superposed position. 7. The roll support and spacing member of claim 6 wherein the first bosses are positioned adjacent to the side walls of the first section and the second bosses are positioned adjacent to the side walls of the second section. 8. An arrangement for supporting and stacking rolls of material in a multi-layer stack of multi-roll layers, each layer including pairs of rolls located in axial end-to-end orientation, the arrangement having roll support and spacing structure having first and second sections foldably interconnected along a hinge with each section having aligned roll-receiving indentations for receiving and supporting rolls so that upwardly facing indentations engage a bottom of an upper layer of rolls and downwardly facing indentations engage a top of a bottom layer of rolls, the sections being separable to provide top and bottom support pieces for engaging rolls in the stack, the sections being movable into superposed relationship with one another, wherein the sections have peripheral flanges along opposed sides and opposed ends thereof which flanges engage each other when the sections are in superposed relationship, the flanges being formed with cooperable interlocking tab and notch structure for positively retaining the sections locked together when in superposed relationship, the flanges further being formed with a plurality of bosses which are engagable with one another when the sections are in superposed relationship to maintain alignment of the sections. 9. A roll support and spacing member comprising: a first section having a pair of spaced end walls, a pair of spaced side walls, a pair of roll receiving indentations and a peripheral flange extending from the pair of end walls and the pair of side walls; a second section having a pair of spaced end walls, a pair of spaced side walls, a pair of roll receiving indentations and a peripheral flange extending from the pair of end walls and pair of side walls, wherein the first and second sections are foldably interconnected along a hinge formed between the peripheral flange of the first section and the peripheral flange of the second section; a tab formed on the peripheral flange of the first section adjacent to one of the end walls of the first section; and a notch formed on the peripheral flange of the second section adjacent to one of the end walls of the second section, wherein when the first and second sections are folded along the hinge into a superposed position, the tab is selectively engagable with the notch for positively retaining the first and second sections in the superposed positions and preventing pivoting separation of the first and second sections along the hinge, wherein the tab and notch each have winged portions to frictionally engage and overlap with each other.
